Employer Branding as a Talent Management Tool: A Systematic Literature Revision

: The aim of this paper is to present a systematic literature revision (SLR) that shows the relationship between the concept of employer branding (EB) and talent management (TM). Based on the EB model proposed by Backhaus and Tikoo in 2004, and the macro-contingent model for talent management introduced in 2019 by King and Vaiman, we intend both to analyse the theory correlating the EB concept and TM, and to identify TM dimensions that are reﬂected on the EB concept. A systematic literature revision was carried out using the Preferred Reporting Items for Systematic Reviews (PRISMA) protocol in order to identify and sum up the most relevant studies of the last 10 years concerning these topics. Findings show that scientiﬁc literature on the subject grew considerably in the last four years, reﬂecting the rising concern over the creation of an employer brand at the organisational level. EB explores talent attraction and retention particularly, though, unexpectedly, is also becoming a concept explored by nations to attract a qualiﬁed workforce. Analysing selected articles, we may conclude that EB is clearly considered as a tool within the largest process of talent management.


Introduction
The market paradigms in existence have suffered a radical change since the 1980s following the changes in the economic paradigm due to the evolution from an industrial economy to a knowledge economy [1].Consumers have become more demanding, and that rapidly resulted in shorter and shorter product and process life cycles.Markets that were, until that point, part of more or less stable economies suffered the impact of globalisation, and 'turbulence, disorder and unstable balance became the main features of the new competitive landscapes' [2] (p.17).
This background of fast changes and the global economy leveraged by technological evolution provided an unprecedented focus on the importance of people possessing knowledge within organisations.Attraction and retention of talent by organisations became consequently more and more strategic and vital to organisational success and sustainability.As mentioned by Michaels, Handfield-Jones, and Axelrod, [3] the biggest organisational competitive advantage is the ability of the organisation to develop and maintain (i.e., manage) talent both in turbulent and stable times.The search for tools capable of managing talent has assumed great relevance over the last decade.EB has emerged as one of the most complete tools based on the culture and reputation of each organisation.
EB provides employer value proposition (EVP) and emerges as a differentiation tool, as well as an identification and employees' commitment mechanism [4] towards each organisation: 'the employers' brand role and impact rise to a new relevance within talent and employees 'careers management' [5].Therefore, the present research aims to show evidence of the importance of the EB concept to talent management, especially as a tool Figure 1.Talent management macro adaptive approach.Source: King and Vaiman (2019) [13].

Employer Branding
EB is not a new concept; back in 1996, Ambler and Barrow [14] (p.8) described the employer brand as the 'functional, economical and psychological package given by a job matching the employer company'.Nevertheless, the concept has been growing to a more relevant role concerning talent management [5].The designers of the first EB model (see Figure 2), Backhaus and Tikoo [15] point out three vital assets to create the employer brand: organisational culture, organisational identity, and differentiating value proposition.(2004).Source: Backhaus and Tikoo (2004) [15].
With the conceptualisation of this model, the authors intend to make the comprehension of the dynamics associated with the concept easier, as well as the importance of the narrow relationship between marketing and human resources to the implementation of an EB process.
Since the expression 'war for talent' was created by Mckinsey-one of the most important human resources consulting companies in the world-in 1997, EB processes have

With the conceptualisation of this model, the authors intend to make the comprehension of the dynamics associated with the concept easier, as well as the importance of the narrow relationship between marketing and human resources to the implementation of an EB process.
Since the expression 'war for talent' was created by Mckinsey-one of the most important human resources consulting companies in the world-in 1997, EB processes have assumed a central role in organisational strategy because organisations realised that they would have to fight this 'war' on the following years if they wanted to attract and retain the talents relevant to their sustainability.Although brands and branding are not a recent topic, organisations are now applying the concepts to new management areas [16].Branding, according to Kotler and Lee [17] (p.215), is 'the identity developing process of an intended brand'.EB is the expression used to refer to the applicability of brand elements to human resources management.Sullivan [18] advocates that EB expresses the notion that designates a company as a good environment to execute functions.
It is of the utmost importance to clarify the concept and systematise its models due to the relevance the concept has been developing over the years, and because the introduction of EB within the organisation is becoming more and more a necessity and no longer an option.Therefore, one of the goals of the present systematic literature revision is the clarification of the concept and its dimensions.

Methods
Conceptualisation and reflection on talent management and EB concepts lead to the question that guides this research: Which dimensions of talent management are reflected in the EB concept?
The proliferation of academic studies and the speed of concepts evolution in recent years demand a systemic approach to access and aggregate these research results to grasp a coherent and integrated sum of investigation results.This supports the choice of a systematic literature revision (SLR) according to the protocol currently accepted by the scientific community.
Bryman [19] lists the following steps to perform an SLR: (a) defining the revision goal and scope; (b) researching studies relevant to the revision scope and aim; (c) analysing and subsequently summarising the results of each study.
We believe that three specific goals operationalise the investigative question mentioned above: (1) analysing the most important studies that link the two concepts, EB and TM, in the last decade; (2) identifying the EB dimensions introduced in those studies; (3) comparing dimensions that emerge from our research with the TM model based on a macro-contingent approach presented in 2019, which includes both macro and micro levels.

Strategy and Research Sources
This research follows the guiding lines of the Preferred Reporting Items for Systematic Reviews (PRISMA) protocol, a development regarding the QUOROM protocol [20] whose aim is to guarantee that systematic revisions are conducted in a complete, clear, and replicable way [21].In August 2009, the PRISMA protocol introduced the PRISMA Statement [20] that clarified several phases of this type of research (see Figure 3).All the mentioned phases were accurately followed in our research, as was a checklist whose aim is the identification of all the items to be included in this type of literature revision.These items were an essential guide to investigators and formed a road map of the present study.
In the present study, data were collected using the B-On website.B-On is a research tool for scientific data that provides simultaneous research in several data resources managed by the Portuguese Consortium B-On, working as a browser that helps to consult the most reputable databases and those with higher impact on the academic and scientific communities.We chose Web of Science (WoS) and Scopus as sources to the most relevant editors-Emerald, Wiley, Elsevier, MDPI, or Sage.The scope and reach of the selected sources allowed us to find credible results and suitable data concerning the proposed systematic revision.In the present study, data were collected using the B-On website.B-On is a researc tool for scientific data that provides simultaneous research in several data resources man aged by the Portuguese Consortium B-On, working as a browser that helps to consult th most reputable databases and those with higher impact on the academic and scientifi communities.We chose Web of Science (WoS) and Scopus as sources to the most relevan editors-Emerald, Wiley, Elsevier, MDPI, or Sage.The scope and reach of the selecte sources allowed us to find credible results and suitable data concerning the proposed sys tematic revision.

Collected Data Analysis
The collected data were submitted to two distinctive analyses, as carried out lately for authors on RSL analyses [22].This method seems to be adequate to achieve relevant conclusions in this kind of research.First, a bibliometric analysis was conducted; its metric results were analysed and interpreted-publication year, sources, quotation number, or countries where research in this study was performed.Second, a content analysis was performed; as intended, the aim was to identify the dimension of EB focused on studies that link EB to TM so that we could conclude about the TM dimensions that reflected EB.

Publication Date
During the first half of the decade in the study, only around 2 articles per year were published (see Figure 5).From 2015 onwards, an annual growth of publications concerning the subject becomes clear, except in 2019.The most prolific year for publications concerning the connection between EB and talent management was 2020-17 articles.Overall, 17% of the scientific production analysed is from 2016 to 2020.Comparing 2018 and 2020 it is clear that the interest in the subject has unequivocally risen in the last 3 years, matching the perception of the growing importance of the subject in the academic arena; dealings of the organisational world have penetrated scientific discussion.

Countries
The included articles were published in 22 countries (see Figure 7).India stands out with a third of all publications: 20 published articles.Worthy of mention is the fact that the African continent only provided 7 articles (slightly above 10%), and 2 of those were published in Mauritius, an eastern African archipelago with a population of less than a million and a half.On the other hand, the Asian continent shows a contribution close to 47% with 28 articles.The second most expressive value is not a country but scientific multinational collaboration; with 10 published articles, it represents about 17% of the total.From the total of 9 published articles on the European continent, a third were published in Portugal.

Citations
In terms of citations, 1166 are present in the total 60 articles under analysis (see Figure 8), in plain terms, an average of 19.43 citations per article.However, a more detailed analysis reveals that both the mode and the median correspond to the interval 0-50.Therefore, we know that most articles contain relatively few citations per article, but 6 articles contain more than 50 citations; this means that 10% of the total published articles contain more than 50 citations.In this case, both mode and median tend to be more reliable because extreme values do not affect them, unlike the mean which is very permeable to this influence.The article with the highest number of citations is also the oldest one, 'Employer Branding and its Influence on Managers' published in the European Journal of Marketing from the Emerald Group Publishing.Next, with 174 citations, the article 'Six Principles of Effective Global Talent Management', published in the MIT Sloan Management Review in 2012.

References by Article
Concerning references, the mode is in the interval of 60-80; almost a third of the articles are on this interval (see Figure 9).Only 1 article presents more than 200 references, and 6 others reveal up to 20 references.Considering references values between 40 and 100, 43 articles were found, which means that these values accommodate most of the studies' references choice to develop their research.We conclude concomitantly that the scientific production itself is fueling new research, but no other inference can be made regarding this selection of articles.This suggests that the quality of the studies is beyond the references upon which the authors based their research.

Content Analysis
In order to address the objectives of the present study, a content analysis of the selected articles was performed (see Table 2) concerning two aspects-on the one hand focusing on the main conclusions, and on the other hand, identifying the EB dimensions focused on each study.

Article Title Main Conclusions EB Dimensions Mostly Explored (D)
'Employer branding and its influence on managers' [25] Results highlight the importance of EB although likewise suggesting its management complexity because none of the aspects reveals dominant influence over the relevant results from the employer perspective; the authors conclude that the area within the organisation that should be responsible for EB is unable to be defined.

D: EB Strategy
'Employees' commitment to brands in the service sector: Luxury hotel chains in Thailand' [26] This study explores EB variables as an explanation for workers' commitment to their organisations and defines those that are directly connected with said commitment.

D: Workers Retention
'Is there a bigger and better future for employer branding?Facing up to innovation, corporate reputations, and wicked problems in SHRM' [27] Three research EB areas can aggregate significant value, and convey important implications to HR practices: Focus on authenticity and on EB.Local and employer's brand's privilege.Focus on the EB role in social capital development.

D: Workers Attraction|Retention 'Rebranding employment branding:
Establishing a new research agenda to explore the attributes, antecedents, and consequences of workers' employment brand knowledge' [28] Organisational attraction measures usually combine attitudinal measures (i.e., affection towards an organisation), intentional measures (i.e., the intention to find a job), and behavioural measures (accepting a job).

D: Workers Attraction 'Six Principles of Effective Global Talent
Management' [29] The article presents six key principles in which successful companies focus to manage talent: alignment with strategy; internal consistency; cultural management; management involvement; balance between global and local needs; and distinctive EB strategies.

D: Workers Attraction|Retention
'Industry branding: attracting talent to weaker profile industries' [30] Research suggests that most of the students who took part in the study consider economical and developmental factors and other benefits more important.Interesting and innovative projects in which state-of-the-art technology can be used are also considered relevant.

D: Workers Attraction 'How to attract applicants in the Atlantic
versus the Asia-Pacific region?A cross-national analysis on China, India, Germany, and Hungary' [31] Comparing students (future applicants) from the four countries being analysed (China, India, Hungary, and Germany), the authors concluded that concerning organisational climate and career prospects the level of importance is similar to all.The balance between professional and personal life is rather important in India and Germany, though much less in Hungary.Functional contents are more appealing for German students but show almost no influence over the Hungarian.

D: Workers Attraction
'Recruiting gen yers through social media: Insights from the Italian labour market' [32] Research findings reveal the 'limited' popularity of social channels/networks as a recruitment tool among the Y Generation.These channels though offer attraction and involvement opportunities among younger generations.

D: Workers Attraction
'What do best employer surveys reveal about employer branding and intention to apply?' [33] Several organisations invest more and more in research about better employees in order to establish themselves as optimal work environments, hence attracting bigger and better talents.Results suggest that the companies that took part consistently or recently in these research efforts obtain a significantly stronger intention of a bigger number of applications.

Article Title Main Conclusions EB Dimensions Mostly Explored (D)
'Leveraging employer branding, performance management and human resource development to enhance employee retention' [34] This article defends that, from the talent point of view, the biggest winners in the emergent economic environment are the organisations providing positive EB, performance management strategies that help employees to develop knowledge, able to maximise their potential, and innovative approaches to design and implementation of HRD strategies.

D: Workers Retention

'Employees or Consumers?The role of competing identities in individuals' evaluations of corporate reputation' [34] In well-established market economies, individuals tend to reveal very distinct identities as workers and consumers; according to the chosen identity, individuals evaluate differently the reputation of organisations.On the other hand, in transitional countries, the consumer's identity prevails over the worker's identity.Therefore, applicants to a job tend to 'follow' their consumer's values when forming judgements about the companies' values.

Conclusions
The first goal of the present study was to analyse the scientific literature of the last ten years indexed to the two most reputed databases in the scientific arena-WoS and SCOPUS-regarding talent management and EB themes, using bibliometric indicators, and content analysis.
This analysis provided a broader understanding that, although the EB process is not clearly structured, some stages can be identified as common [24] and serve as indicators that bring light to the concept according to the most successful companies in practice.Authors suggest that EB is in fact a reformulation of the long-term used notion of 'internal or HR marketing' and still lacks a lot of innovation [16].On the contrary, though the majority of findings point out that this is a simplistic approach because the concept has become extraordinarily important to organisational success, encompassing the employer brand proposed value and fundamental dimensions to employees' attraction and retention such as affective commitment [4], rewards strategies [70], commitment expectations [26], reputation [68], or employees' development [49].
While exploring the selected articles, we clearly understood the connection between talent management and EB; there are studies defending that organisational talents management is strongly related to EB perception [70] and that a positive employer brand is essential to attract and retain the best talents, conferring a competitive advantage to organisations [50], considering that HR employees believe in a strong connection between EB and talent strategic management [45].
Concerning our second goal-identify EB dimensions explored by the authors-we identified four main EB dimensions among the selected articles: employees' attraction (18 articles), employees' retention (16 articles), simultaneous employees' attraction and retention (17 articles), EB strategies (models, conceptual, analytical frames, 7 articles), and national EB (2 articles).Regarding the latter, the articles surprisingly establish an analogy between organisational EB and the way countries should apply the concept to nations in order to attract a qualified workforce.This shows how attraction and retention of talents have become major EB concerns; talent attraction alone is analysed in approximately onethird of the selected articles, a fact that underlines the notion that this is a tool used by organisations to enhance their attractability in the market; therefore, securing a talent pool grants them a quality of choice at the moment of selection.
The strength of the connection between the keywords analysed with VOSviewer also shows that EB is directly linked with recruitment, and talent management is connected with EB through strategy.This strongly reaffirms that EB is a tool included in the broader process of talent management regarding the promotion of the EB power of attraction enhancement.
Concerning the last goal of the study-identifying talent management dimensions contained within the concept of EB-from the analysis of the talent management model present in Figure 1, we conclude that some intra-organisational talent management dimensions are always explored by EB, having employee's attraction and retention in mind: recruitment and selection, engagement and retention, and rewards.We unexpectedly found out that EB is also starting to provoke impact at the macro (extra-organisational) level of the same model due to the creation of national EB.We were able to answer the question that guided this SLR and conclude that talent management is much broader than anticipated because of the dimensions that do not concern EB, but on the other hand, EB is a powerful tool to achieve talent management goals, as it addresses key dimensions of talent management.
It is in our opinion worth noting, considering the digital revolution we are living in today, that despite more recent years being those that clearly concentrate the largest scientific production in this field of research (70% of the selected articles range from 2016 to 2020), only four articles directly mention digital resources as a privileged mean of disseminating and reinforcing EB strategies.From a certain perspective, this can be interpreted as a gap that prevents the dialogue between organisations and the diverse generations nowadays in the market, some already born in the digital era.Gregorka, Silva, and Silva [24] defend that the EB process and its consequences have not yet been fully studied, despite the common use of the concept in the past 20 years.Many cited authors likewise refer to the need for innovation and larger consistency regarding the concept.Therefore, we conclude that though unquestionably being a major theme, the organisational world still has at present a long road ahead of it to improve the knowledge and definition of EB models and strategies that would enable the organisations to make better use of this tool on their 'war for talent'.
By providing a summary of the most relevant literature of the past decade and exploring its findings, the present study contributes overall to the continued scientific effort of knowledge enhancement in this field of study.The obtained results bear important guidelines to both academics and managers linked to talent management, suggesting new pathways for further investigation to shape the concept of EB more consistently and to clarify which are the truly relevant dimensions to build a positive and distinctive employer brand.
As with any other research, we have encountered limitations, especially concerning the non-compliance of some selected articles with language criteria and, above all, with the fact that many were not directly related with the subject though presenting the defined keywords because they focused on details not relevant for our research.
