3.2. The Components’ Importance Level
3.3. Correlation between PSS Components
3.4. The Sustainability-Related Components
4. Discussion
5. Conclusions
- The elaborated PSS component can explain, based on previous research and customer perspectives, the way that PSS constituents play an essential role in the value-creation process. This means that attention in the development of PSS can be focused on developing and managing these components effectively and efficiently.
- The importance of the PSS components presented in Table 9 and Figure 2 can be utilized to consider which component of the PSS development to start with. The level of importance was calculated based on the customers’ perspectives so that PSS development is carried out in line with customer priorities.
- Correlation analysis between components helps determine the impact of the development of one component on other components so that anticipatory and efficient actions can be taken.
- Component analysis related to sustainability aspects can be used for the development of sustainable PSS that is component-based and convergent so that the efforts made are practical and efficient.

No | Type of PSS | Properties |
---|---|---|
1 | Type 1: Product-Oriented | The firm sells the product and provides the necessary services for its use. |
The firm provides guidance or consultation on how to use or the most effective way to use the products it sells. | ||
2 | Type 2: Use-Oriented | Ownership of the product rests with the firm, not the customer. The firm is responsible for carrying out maintenance, repair, and control. The customer, also known as the lessee, pays a regular fee for using the product. However, the leaser has unrestricted access or use rights to the leased product. |
The customer does not have unlimited access or use rights to the product. Meanwhile, product ownership and responsibility for maintenance, repair, and control are still with the firm. | ||
Multiple partners are gathered in one location, and the product is simultaneously utilized. | ||
The customer no longer purchases the product but instead pays a fee based on the product’s output and level of use. | ||
3 | Type 3: Result-Oriented | The firm’s tasks are delegated to third parties through outsourcing contracts, but the quality of the work is still monitored using performance indicators. |
The firm conveys results, which can be in the form of products or services, to clients. |
