Proposed Analytic Framework for Student Relationship Management based on a Systematic Review of CRM Systems Literature

: Notwithstanding the research attention given to the importance and capability of the student relationship management strategy in higher education sustainability, there is no any systematic framework for implementation. This research as one of the preliminary studies has been undertaken to provide a structural framework of strategic practices for positioning this strategy at an operational level. In doing so, a methodological approach was implemented in two tiers. Firstly, a systematic review of the leading-edge literature on the customer relationship management systems was performed owing to the lack of signiﬁcant research on the topic, as well as the structure and nature of the concept. Then, the principal components factor analysis with varimax rotation, which is a method of exploratory factor analysis was used to ﬁnalize the research. The ﬁndings revealed an articulated structural framework with ﬁve hypotheses, which may partially or fully be applied to narrow the major gap in the current knowledge. The measurement scale has also been developed for simpliﬁcation in implementation of the application. Limitations and directions for future research were accordingly discussed. quest engines,


Introduction
The theme of student relationship management (SRM), which emerged from the customer relationship management (CRM) system, has established itself as a distinct identity for research over the last decade (See Table 1). Hilbert et al. [1] (p. 209) described it as "a fundamental strategic orientation of the entire academy aiming at the increase of student satisfaction and the creation of additional value for the students as well as for the academy". Ackerman and Schibrowsky [2] stressed the importance of SRM as "an institutional philosophy, which contributes a different view of the institution's interactions with students (p. 328)". They found the higher education future in shaping the sustainable relationships with students under this notion, which agrees with the standpoints of Rowley [3] and Seeman and O'Hara [4], who believe sustainability in the educational institutions depends on the ability to make paradigm shifts in the system, as well as the capability to construct the meaningful relationships with both current and potential students. Going through the literature, as summarized in Table 1, it is found that SRM constitutes a strategic orientation for maximizing the student value through meeting the students' needs, as well as for advancing the institutional sustainability through sustainable relationships development.

While the significance of implementing an effective SRM has been stressed in the educational institutions that are the academic powerhouse in creating the needed human capital to support sustainable development, there is insufficient empirical and theoretical research. To date, no previous studies have explicitly and systematically addressed a comprehensive framework/model of SRM. Surprisingly, it is in accord with the investigation of Hilbert [1], who concluded that a common model is still missing, highlighting the major gap regarding this missing link in the educational systems. Thus, an opportunity exists for innovative research. This study has attempted to make a valuable contribution theoretically and empirically, with the objective of providing a framework that positions SRM at an operational level.
To achieve this goal, this article has been designed as follows: Section 2 clarifies the research methodology to implementing the study's objective; Section 3 presents the theoretical framework obtained by a systematic review, indicating how the CRM system was adopted and applied for developing the SRM strategy. This leads to providing a hypothetical account; Section 4 reveals the results and findings obtained by the analyses according to the research methodology step by step; Section 5 describes an integrative discussion of the research results and findings; Section 6 provides a conceptual framework and hypotheses as well as the limitations for future research; and Section 7 outlines the final conclusions.

Research Methodology
This research is an exploratory research, as performed for a problem that has not more clearly been studied so far. From the exploratory objective viewpoint, it is descriptive and analytic. It begins with a systematic review of the literature at the first step and proceeds with an analytic approach to finalize the research at the second step. These steps discuss in more detail below.

Systematic Review
As mentioned earlier, the SRM strategy was emerged from the CRM system-moreover, no systematic efforts have been made to operationalize this strategic approach. Therefore, this step is aimed at clarifying the CRM concept and exploring its strategic practices. To do so, a systematic literature review has been performed for this investigation. This type of reviews is particularly useful for (a) conducting an in-depth analysis of the leading-edge research and integrating the result of research on emerging matters [14] and (b) evaluating and summarizing the existing studies that address a particular issue and providing a framework/background, so as to properly place new studies activities [15]. Two main actions for performing this review are taken out in this step of the research, as addressed below.

Designing the Review Protocol
The protocol is a crucial part of any systematic review [15]. To design a review protocol for this study, a quality assessment checklist according to Kitchenham [15] was applied to assess the individual studies published in the ISI Web of Knowledge and Scopus databases from 2000 to 2017. Accordingly, the checklist involves the following questions: (1) Does the article clearly specify the methodological approach? (2) Is the methodological approach relevant to the problem under study? (3) Does the article properly perform the analysis? If the article fulfills the quality criteria, then it is eligible to include in this review.

Selecting the Articles
Three main stages for selecting the articles have been implemented in this study as follows: The first stage involves a systematic search for studies associated with CRM from 2000 to 2017. The ISI Web of Knowledge and Scopus databases have been employed as the quest engines, for various keywords including "customer relationship management", "CRM", "successful CRM", "CRM models", "CRM critical success factors", "CRM strategic practices", and "CRM scale development".
The second stage begins by focusing on journal publications: the conference papers, editorial material, book review, meeting abstract, correction, retracted publication, book chapter, and reprint were excluded. Next, searches were administered in the publishers' databases including Elsevier, Taylor & Francis, Emerald, Springer, Sage, and Wiley. The search has also eliminated the studies that were not available for download or not written in English.
Finally, the authors have individually studied the full text to take the papers into consideration. The articles that did not discuss CRM from a practical/operational point of view were also excluded from the review. This restriction has secured the concentration on the theoretical-empirical publications associated with the issue. As a result, 20 remaining articles were taken into account for further analyses. These 20 papers that meet the assessment criteria were particularly studied as a critical appraisal of the content, which was outlined in Section 3. The outcome of this appraisal has briefly been described in Table 2. Table 2. Literature comparison against the customer relationship management (CRM)'s strategic practices, with the addition of the objective(s) of each analyzed study.

Analytic Approach
This step is aimed at measuring the exploratory variables, assessing the reliability of measurement scales, and forming a smaller number of coherent subscales with a minimum loss of information, defining the fundamental structure among the variables assumed. In doing so, the exploratory factor analysis (EFA), which is a method of factor analysis, is employed. Three main actions for implementing this method are taken out in this step of research, as explained in the following parts.

Designing the Exploratory Survey
To design a EFA, two basic questions should be addressed [36]: (1) What variables are involved? and (2) what is the desired sample size to measure the variables? The first question has been addressed based on a review of the state-of-the-art literature on the CRM system owing to (1) the lack of significant research on the topic and (2) the structure and nature of SRM. Therefore, to create the initial variables relating to the SRM strategy, the authors examined the significant checklists of the articles relevant to the CRM system that were commonly applied by researchers. This exploratory review was in pursuit of the notion that CRM success is predicated on addressing the main ones in the four core domains, as described in Section 3. Consequently, 36 variables were identified and modified according to the variable-based checklist of Garrido-Moreno and Padilla-Meléndez [25], who have explicitly and systematically addressed the developed scale of leading articles, particularly [21], to develop their checklist. These variables, along with the respondents' answers on them have been presented in Figure A1.
In operational and managerial studies, the non-probabilistic convenience sampling can be employed to obtain primary data concerning the specific issues such as collecting opinions of respective customers with respect to a new design of a product or service. This technique of sampling has widely been applied, and its sample collection process is continued until the expected sample size is met [37]. Due to varied rules of thumb, there is a lack of consensus on the sample size necessary to utilize EFA [36,38,39]. Hair et al. [36] recommended that the minimum absolute sample size should generally be 50 observations, and preferably it needs to be 100 or larger in implementing EFA. Moreover, Sin e al. [21] and Nejati and Nejati [40] have approved their exploratory survey on data obtained from a study with 150 and 125 samples, respectively. Therefore, in this study, in order to examine the initial variables and to reveal its factorial structure, 151 samples were totally collected from the local and international students of the Universiti Teknologi Malaysia (UTM, Johor Bahru, Malaysia), that is a top-ranking research university in Malaysia. There are a variety of ways, settings, and sources to collect data in the survey research, which has had a significant history and contribution to advancing the scientific knowledge. Questionnaires are considered to be the main method to collect data in such research [37].
Once the variables and sampling are specified, the correlation matrix can be assessed to apply EFA to recognize an underlying structure of relationships. In this regard, the decisions must be produced regarding (1) the selection of a factor method for extracting the factors and (2) the specification of a factor matrix for revealing the underlying structure of the data [36].

Selecting a Factor Method and Specifying a Factor Matrix
In the available literature, the principal components factor analysis, also known as component analysis with VARIMAX rotation has widely been used [18,19,21,25,28,31,40,41], which is in accord with the reviews of Conway and Huffcutt [38] and Plonsky and Gonulal [39] on the topic. The main advantage of this method is to consider the total variance and determines factors that include small proportions of unique variance. The varimax rotational approach maximizes the aggregate of required loadings variances of the factor matrix. It is fundamentally simple and appears to provide a clearer division of the factors. In general, this method has successfully been demonstrated as an analytical approach to getting an orthogonal rotation of factors [36]. Therefore, this study has taken into account this type of method to generate a fundamental structural framework. To do so, SPSS software has been employed.

Testing Reliability and Validity
Factorability and adequacy of sampling are examined through Bartlett's test of Sphericity (BTS) and the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy. These tests are particularly advised when the participant-to-variable ratio is smaller than 5:1 [42]. The BTS should be significant at the 0.05 significance level, and the KMO index that varies between 0 to 1 with minimal adequacy as 0.5 was considered suitable for a good EFA [36,42].
The criteria most commonly applied to distinguish the total factor number for extraction are: (1) the percentage of contribution to the total variance, the principal factor should exceed 20% in the valid scales; (2) eigenvalues-each factor should be greater than one; and (3) scree test-a test to optimum the number of factors that should be extracted [36,43]. Furthermore, following the criteria set by Heir et al. [36], factor loadings exceed 0.45 are regarded significant according to the sample size.
Finally, the internal consistency coefficient, also known as the reliability coefficient (Cronbach's Alpha) is calculated to assess the consistency of the entire scale. It should be more than 0.6 in the exploratory survey [36,40,41,43].

Theoretical Framework
In the early 2000s, the concept of CRM with a distinct identity was constituted to be a customer-centric relational managerial approach. According to the descriptive classification of Zablah et al. [44], CRM is described in the available literature as a (1) process [18,19,21,30], aiming at establishing the relational flows and developing the process of creating and sustaining a fully profitable portfolio of relationships with the customers; (2) strategy [16,19,[21][22][23]25,[32][33][34]45], aiming at embedding the customer satisfaction-retention-loyalty chain to develop sustainable relationships with the customers that are (potentially) valuable; (3) philosophy [44], aiming at achieving customer centricity for the organizational sustainability; (4) capability [29], aiming at developing the organizational knowledge and capability to construct the sustainable relationships with the respective customers toward business excellence; and/or (5) technological tool [17,24], aiming at mingling marketing, sales, and knowledge-capable systems to create partnerships.
Many benefits of implementing a successful CRM have been identified across the literature. Croteau and Li [16] highlighted the CRM benefits in enabling products and services customization, providing a "one-to-one" experience of customers, improving efficiency and effectiveness of sales force, and enabling customized marketing plan for each customer. Reinartz et al. [18] enumerated the benefits in improving pricing, enabling segmentation according to customer economic value, and improving resource allocation to accounts. The most complete enumeration of these benefits was stated by Richards and Jones [46], who highlighted seven core benefits as CRM value drivers including (1) improvement of the ability to target profitable customers; (2) integration of offerings throughout channels; (3) improvement of the efficiency and effectiveness of sales force; (4) individualization of marketing information; (5) customization of products and services; (6) improvement of customer service efficiency and effectiveness; and (7) improvement of pricing. Practically, it is found the organizations that encompass advanced customer relationship strategies have successfully established a state-of-the-art CRM system, for example, MBNA Europe has implemented CRM through marketing the apt products to the apt customers and there was an annual profits increase of 75% since 1995, Wells Fargo with implementing a successful CRM has drastically experienced customer satisfaction, and/or Amazon that has been achieved to a high prosperity by its customer proposition as well as CRM training for the employees [45].
Khodakarami and Chan [47] elaborated the types of CRM systems by drawing on [48][49][50][51][52][53] research. These systems have mainly been fallen into three classes including operational CRM systems, which utilizes for automating the CRM processes and improving their efficiency and productivity; analytical CRM systems, which utilizes for analyzing the customer data and knowledge; and collaborative CRM systems, which utilizes for managing and integrating the channels of communication and customer touchpoints. The point at issue is how to implement. According to Sin et al. [21], a more comprehensive theory/conceptualization that contributes new outlooks and appends to the available system of knowledge can be created through the appropriate replications, extensions, and generalizations. The present research has systematically recognized and reviewed a certain amount of these replicative and creative studies, as summarized in Table 2. It is found that the development of CRM system is largely being addressed through integrating and balancing of the main factors based on the principles and ideals that (1) reflect CRM as a multi-dimensional strategic application and (2) involve three critical dimensions, that is, technology, people, and process. There has been a developing frame of the literature that reveals the importance of four critical factors for successful implementation ( Table 2). It is believed that an integrated and balanced approach to these tangible strategic practices paves the way for implementing a CRM system effectively. According to Garrido-Moreno and Padilla-Meléndez [25], they should be analyzed and improved in each case and structure to investigate the structural integrity. These strategic practices have been discussed in detail below, so as to provide a hypothetical account. Moreover, the authors have presented an imaginable and/or graphic model, as shown in Figure 1, which indicates a holistic perspective of the CRM system in accord with the aforementioned principles and ideals. It may help to the conceptual richness that is complicated to express explicitly and succinctly with terms.

Knowledge Management
Knowledge management (KM) is mostly considered as a plan for directing the organization toward its goals [54]. Therefore, it is outlined as the process of recognizing, using, sharing, and managing knowledge to help the company enter into a competition [55]. Rastogi [56] describes KM as a systematic comprehensive process to fulfill organizational aims through creating, sharing, developing and employment of knowledge by members of a community. The viewpoints on knowledge given by Alavi and Leidner [57] clearly hypothesize this idea. In perspective of knowledge as (1) a state of mind, KM focuses on improving individual's learning and understanding by providing information; (2) an object, KM focuses on developing and managing the knowledge stocks; (3) a process, KM concentrates on the knowledge flows and process of acquiring, diffusing, and applying knowledge; (4) an access to information, KM concentrates on systematic access to and information retrieval; and (5) a capability, KM is concerning constructing core competencies and realizing strategic know-how [57].
There are many evidences of the positive influence of KM on CRM success, and, consequently, the organizational performance internally and externally [16,17,[19][20][21][23][24][25][26][27][29][30][31][32][33][34][35]. From a viewpoint of CRM, knowledge can be regarded as the experiential learning for the sake of excellence [21]. Converting information into knowledge could be used to improve new products and services as well as to design communication plans for attracting customers and constructing the long-lasting relationship with them [16].
Following this viewpoint, KM capability is described as the ability of a company which involves capturing, handling and supplying products and services information for the customer. Therefore, there is an increase in customer response and the decisions are made fast with respect to the reliable information [25]. However, KM is emerging as a key concept and frequently reported as an antecedent of innovation. Hence, when implementing CRM, a decisive role will be given to KM which makes a change in the organizational vision. Consequently, learning and innovation occur in a great deal within the organization to succeed.
Knowledge management and its initiatives in the KM-capable CRM system are largely regarded as a process involving the key facets, as follows: (a) knowledge acquisition, that is a professional procedure through which the existing information is used to learn new knowledge; (b) knowledge application, that involves the business procedures in enabling an organization to access knowledge easily through effective storage and retrieval mechanisms; and (c) knowledge diffusion, that is described as the business procedures that share knowledge among all people joining in process events. In general, according to [25], CRM and KM initiatives are aimed at delivering a continuous improvement for the sake of the customers. This would contribute to build up better relationships with the customers, increase their approval and accomplish business excellence.

Organizational Elements
This factor (OE) is aspects of doing with the organizational structure, human resource management, and resource allocation [19,21,25,27]. It is considered implementing the CRM system necessitates changes in the way an organization is organized as well as in its business processes [21], highlighting the need for a model that includes the variables measuring the significance and consequence of these organizational factors on CRM success. According to Garrido-Moreno and Padilla-Meléndez [25], the implementation of the successful CRM requires redesigning the organizations and reorienting the value chain toward the demand. Therefore, so as to succeed in implementing CRM that depends on building the appropriate synergy between the technological tools, processes, and people [21,25], the aspects of this factor require being transformed into the organizations.
Mendoza [22] pointed out the human factors are critically important in this context. It is critical in organizations due to the relationship of humanity with the complex processes and the high-level systems as well as the inter-human relations, which has had a determinative function in implementing any organizational strategy. Hence, the factor of employees' involvement that concentrates on providing training, motivations, and opportunities has specifically been determined in implementing the CRM system. Additionally, it includes a direct impact on the impressive performance of the organization's culture, which plays a pivotal role in knowledge management [25]. Based on Reinartz et al. [18], if organization embeds the importance of CRM-based activities in their employees, the organizational structural change to expedite these activities and engage the employees will be more likely.

CRM Technology
An increasing number of the literature, as outlined in Table 2, signified that the CRM technological tools should be taken into account as a fundamental factor in performing the concept. Sin et al. [21] emphasize how the CRM software systems are important for organizations to provide a customized service with higher quality, but at the lower cost. Most of the customer-based activities would not be possible without an appropriate system [18,19]. Consequently, it is believed that establishing the right technology can be leveraged to succeed.
Garrido-Moreno and Padilla-Melendez [25] argues that the CRM technological systems contribute numerous benefits to organizations including providing a customer single view, managing the customer relationships in a comprehensive way regardless of the communication channel applied, and improving the efficiency and effectiveness of the processes defined in relationships with customers. Yim et al. [19] believe CRM technology assists organizations in collecting, sharing and analyzing information from customers, developing communication quality about customers, and configuring the tailored products for customers. It also expedites the customer cross-referencing within divisions of an organization for greater sales initiatives. Nonetheless, the review of literature revealed that organizations should not consider the technology as an only enabler of its CRM; should take account of it as a necessary but not sufficient condition. According to Cambra-Fierro [34], technology is not all for CRM success.

Customer Orientation
The clarification of the role of customer orientation (CO), which has explicitly been described by Narver and Slater [58], as "the sufficient understanding of one's target customers to be able to create superior value for them continuously (p. 21)", in the modern CRM and progressed organizations has evolved over the last two decades. It encompasses the degree to which a company stresses meeting the customer wants and needs for its service quality [59]. Bentum and Stone [60] argued that CO is a type of organizational culture, which must be part of the organizations' implicit assumptions. There are many empirical evidences that reveal this factor as a critical importance of business excellence [27].
Following the investigation of Narver and Slater [58], Garrido-Moreno and Padilla-Melendez [25] assumed that CO demonstrates having an adequate understanding of the customers to be able to give them greater added-value as well as establishing the customer at the center of organization's activities to develop long-lasting relationships. Therefore, organizations should take into account the necessity of having a holistic view of this orientation in their visions. A company that is actively oriented toward the customer can improve the organizational performance in the ever-competing global market by reason of the cultural excellence, which lead to improving employee understanding of the customers. Consequently, CO has been considered to be an indispensable prerequisite to succeed in CRM implementation.

Results
This section is performed through the procedure with the research methodology step by step, as presented in detail in Section 2. Accordingly, the detailed analyses and findings on the steps outlined in the research methodology are reported in the ensuing segments.

Results of the Systematic Review
A systematic literature review was conducted to identify and align the strategic practices of the CRM system, and, consequently, to develop a framework of the SRM strategy that is an emerging field of inquiry. Table 2 shows the results of this systematic review against the CRM's strategic practices. Twenty theoretical-empirical articles could be classified according to the following practices: (a) CRM technology and organizational elements, considered by all of the articles; (b) knowledge management, considered by 17 articles; and (c) customer orientation, considered by 14 articles. Additionally, Table 2 describes the objective(s) of each analyzed study. Accordingly, the results revealed the importance of four critical factors to the CRM success, which were applied as starting points to develop our survey. In pursuit of the aim, the studies by Sin et al. [21] and Garrido-Moreno and Padilla-Meléndez [25] were found noteworthy among others, helping the authors to develop the survey questions/the variable-based checklist.

Results of the Analytic Approach
EFA was performed to reveal the current structure of SRM with 36 determined variables and subsequently create a structural framework of the developed scale. In doing so, the principal component factor analysis was employed to analyze the received scores from the responses provided by the 151 respondents, who were studying and requesting the service education in the Universiti Teknologi Malaysia (UTM, Johor Bahru, Malaysia). The demographic profile of the participants was conducted according to Nejati and Nejati [40], which is as follows: In terms of gender, 70 of them (46.4%) were female, 81 of them (53.6%) were male. In terms of age group, 57.6% were below 25 years of age, 39.1% were 26 to 35 years, and 3.3% were 36 to 45 years. Both local and international students were engaged; 95 of them (62.9%) were international and 56 of them (37.1%) were local. According to the higher education level, 28.5% of the total respondents had undergone bachelor's degree, 53% of the total respondents had undergone Master's degree, and 18.5% of the total respondents had undergone PhD study. Based on period of study in the current university, 27.8% had less than 1 years, 44.4% had 1 to 2 years, 21.9% had 2 to 3 years, 4.6% had 3 to 4 years, and 1.3% had more than 4 years' experience in their careers.
A five-point Likert scale on a continuum from 1 (strongly disagree) to 5 (strongly agree) was implemented to measure the variables, as shown in Figure A1. The overall reliability coefficient (α) of the survey was equal to 0.95, which is an appropriate consideration. The responses on the identified variables have clearly been illustrated in Figure A1. Table A1 displays the correlation matrix for the 36 variables of SRM strategy. Analysis of the correlation matrix shows that most of the correlations have been significant at 0.01 level, which reveals a sufficient basis for advancing an empirical investigation of sufficiency for EFA on a general basis as well as for each variable. The BTS and KMO tests were also performed to ensure adequacy of sampling and evaluate the data factorability. In this study, the BTS found to be significant at p < 0.001 and the KMO index was equal to 0.922, indicating the data is fitting for implementation of EFA.
Next, the percentage of contribution to the total variance, eigenvalues, and scree plot-the criteria most commonly applied to distinguish the total factor number for extraction-were taken into consideration. Initially, the EFA on the SRM variables extracted seven factors with the total variance 60.755% and eigenvalues greater than 1.0. The scree plot demonstrated that six factors were steeply descended and then levelled off, indicating the data should be analyzed for six factors. Hence, six of seven factors were extracted by one variable per each factor with a loading exceeding 0.45. Ten variables-V4, V8, V9, V15, V22, V23, V24, V25, V27, and V32-were accordingly excluded due to lack of the specified threshold. Consequently, 26 out of 36 initial variables were methodically retained in this survey, with factor loadings higher than 0.45. The overall reliability coefficient (α) of the variables was calculated at 0.938, which is considered significant. These developed variables have distinctly formed six factors with the total variance explained 63.190%, as follows:

•
The first factor with eigenvalue 10.326 involved seven variables including V2, V26, V3, V1, V5, V16, and V28 with significant loadings 0.681, 0.661, 0.639, 0.631, 0.596, 0.572, and 0.527 respectively, which are considered appropriate. The variance proportion explained by this primary factor was estimated 39.714% of the total variance, indicating the attendance of one principal factor at the internal consistency of the factorial structure of SRM strategy. According to the common characteristics of the loaded variables, this factor focused on recognizing and acquiring domain knowledge about an application. Thus, this factor was named "Knowledge Acquisition and Application (KAA)". The reliability of the KAA's construct through the internal consistency coefficient (α) using SPSS was calculated at 0.855, which is significant. Consequently, the examinations proved the validity of this articulated seven-variable construct.

•
The second factor with eigenvalue 1.475 involved six variables including V35, V36, V31, V33, V34, and V20 with significant loadings 0.738, 0.651, 0.624, 0.617, 0.504 and 0.482, respectively. The variance proportion explained by this factor was estimated 5.672% of the total variance. According to the common characteristics of the loaded variables, this factor focused on having the right technology to facilitate various activities involved in student relationships. Thus, this factor was named "SRM Technology (SRMT)". The reliability coefficient of SRMT's construct was calculated at 0.857.

Discussion
The results of this research are categorized into two tiers according to a well-defined methodological approach based on the project purpose-providing a framework that positions SRM at an operational level.
Firstly, due to the lack of significant research on the SRM strategy as well as the structure and nature of the concept, a systematic review has been performed to examine the nature of CRM system and present its strategic practices based on a holistic perspective which reflects a co-creation process to achieve a maximum of value across the lifecycle of relationship. It is essential to ensure that the SRM's knowledge develops into a cumulative manner as an emerging field of inquiry. The findings revealed that CRM is a multi-dimensional system, involving three critical dimensions including technology, people, and process. This is important because CRM technology is often incorrectly equated with CRM, and a key reason for CRM failure is viewing CRM as a technology initiative [18,21]. In this regard, the findings highlight the importance of four strategic practices: knowledge management (KM), organizational elements (OE), CRM technology (CRMT), and customer orientation (CO). It is believed that an integrated and balanced approach to these tangible practices paves the way for implementing a CRM system successfully. A summary of this review has been shown in Table 2, where the main studies in this field were characterized against the CRM's strategic practices. In addition, a holistic perspective of the CRM system based on the principles and ideals has been illustrated (Figure 1), which would contribute to the conceptual richness. Consequently, the outcomes of this systematic review were applied as starting points to develop the exploratory survey.
Secondly, an analytic approach has been implemented to developing the SRM strategy based on a student-as-customer perspective, which reveals an integrated framework to operationalization. In doing so, the principal components factor analysis with varimax rotation-a method of exploratory factor analysis-was used to measure the exploratory variables, assess the reliability of measurement scales, form a smaller number of coherent subscales with a minimum loss of information, and, consequently, to provide a structural framework among the variables assumed. In this regard, a three-step instrument development process was generated: (1) identification of variables associated with SRM and development of variables pool; (2) An exploratory study on 151 students to measure the identified variables to improve the content and reveal the factorial structure; .051 respectively. It may seem that some of the variability is unaccounted for, however, 63.190% explained variability was considered as sufficient explanation of variance. The overall reliability of the structure was also measured with a reliability coefficient (α) equaling 0.938. Accordingly, the internal consistency and reliability of the structure of SRM strategy were statistically and analytically approved. The analyses indicated that there were strong relationships among the recognized factors throughout the model. This is in accord with References [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], who have theoretically hypothesized there are significant relationships between the strategic practices ( Table 2) and CRM results/success. Empirically, Yim et al. [19] indicated these four critical dimensions significantly influence CRM results. Sin et al. [20] proved that there is a strong correlation between four key practices. They have consequently developed a reliable and valid scale for measuring the practices. Following the investigation of Sin et al. [21], which were frequently applied by the researchers, Garrido-Moreno and Padilla-Meléndez [25] have systematically found positive influences in CRM success of all factors (KM, OE, CRMT, CO). Also, Garrido-Moreno and Padilla-Meléndez [25] demonstrated that the factor of CRM experience positively affects CRM results. Abdullateef and Salleh [27] by mainly drawing on [19,21] research among others, showed the factors of KM and CRMT are significant and influential. In general terms, Padilla-Meléndez and Garrido-Moreno [32] observed that all key factors positively affect CRM implementation success. Moreover, Croteau and Li [16] argued that CRM success is significantly determined by OE and KM supported by CRMT. Notably, the assertion of Croteau and Li [16] has been supported by the findings of Love et al. [23], stressing that CRM system is much more than technological innovations and is not solely technology-driven.
The findings highlight that SRM strategy could meaningfully be linked to the strategic practices of the CRM system, arguing that the CRM system is internally consistent and reliable for interpreting and developing the SRM strategy in higher education institutions. Therefore, based on the content of the factors analyzed by this investigation, a conceptual framework according to the systematic literature review is provided in detail in the next section. This framework would contribute a helpful reference to narrow the major gap in the current knowledge of SRM strategy.

Conceptual Framework and Hypotheses
Based on the results and analyses of this study, a conceptual framework according to the research objective is presented in Figure 2, which links the SRM results and the four strategic practices. Accordingly, the following hypotheses have been formulated:  Also, the framework ( Figure 2) demonstrates potential correlations among the four strategic practices. In other words, in addition to the above four hypotheses, another hypothesis is developed to explore the relationship among the four strategic practices, namely: Hypothesis 5 (H5). The strategic practices are interrelated and there is a strong relation between them.
Following the conceptual framework, the measurement scale has been reformatted and proposed that can be applied by researchers and the educational decision makers to measure the SRM's strategic practices, and, consequently, to assess the structural framework. This proposed scale has been shown in Table A2. The repetitive and innovative investigations are needed to confirm and develop the structure's integrity.

Limitations and Further Research
This research as one of the preliminary studies is undertaken to create a conceptual model of SRM strategy. In this regard, the research findings, which have been indicative rather than conclusive, are subject to the limitations that suggest directions to further research. Although it is endeavored to encompass the critical aspects of SRM by thoroughly reviewing the state-of-the-art literature on the CRM system, there may be other critical factors which should be taken into account. It may include the mediators that should be examined. In some cases, including new items and/or excluding original items may be needed. This research has paved the way for a more detailed exploration through providing a systematic literature review as briefly presented in Table 2. The analyzed studies in this table would be useful to explore more insights into probable causation.

Conclusions
The research for this article has been built upon the discussion regarding student relationship management, so as to develop the concept with a distinct identity. Going through the literature on the topic, as briefly described in this study (Table 1), it is observed that SRM was emerged from the customer relationship management system-moreover, no systematic efforts have been made to operationalize this strategic approach. There is a need for innovative research. Following this aim, the research objective was determined in providing a framework that positions SRM at an operational level.
In doing so, a methodological approach was implemented in two tiers. The first tier has theoretically revealed the results of a systematic literature review on CRM system based on a holistic perspective. This kind of review has proven to be useful for addressing a framework to appropriately constitute new research activities on emerging issues. The main investigations in this field were characterized against the CRM's strategic practices (Table 2). Next, a hypothetical account of the practices was presented. Moreover, a graphic perspective that may advance the field was illustrated (Figure 1). The second tier has empirically revealed the results of an exploratory factor analysis on a variable-based checklist obtained by the aforementioned tier. This type of analysis has proven useful for creating a fundamental structural framework. The outcomes of this analysis verified an articulated structural model with five critical factors including knowledge management, SRM technology, student orientation, employees' involvement, and SRM results. The findings argued that the CRM system has internally been consistent and reliable for interpreting and developing the SRM strategy in the educational institutions, highlighting that SRM strategy could positively be linked to the strategic practices of the CRM system. Consequently, a conceptual framework of SRM with five hypotheses has clearly been proposed (Figure 2), which may partially or fully be applied to narrow the major gap in the current knowledge of the SRM strategy. Additionally, the measurement scale was developed for simplification in implementation of the application (Table A2). Limitations and directions associated with the framework for further research were also discussed.
In general, this study shows an up-to-date investigation in the current area and involves both theoretical and practical insights. Notwithstanding the research attention given to the importance and capability of SRM, so far there has been no any systematic framework for implementation. This research as one of the preliminary studies was undertaken to propose a systematic framework of strategic practices based on the principles and ideals, which reflect SRM as a multi-dimensional strategic approach and encompass three critical dimensions including technology, people and process. Proposed conceptual framework may strengthen the cutting-edge research for the sake of developing the successful SRM system. It may also constitute a guide for decision makers in higher education systems toward implementation of an effective SRM. Moreover, it may complement the research on advancing the institutional sustainability, which is subject of growing interest in various educational establishments.
