“…To address the research needs identified, a new approach for modularisation of PSS is being developed and presented in the next section. The approach is based on the Life Phases Modularisation according to Blees et al (2010), which has been validated and continuously improved in a number of research projects (Krause et al, 2014;Greve et al, 2020). The Life Phase Modularisation combines technicalfunctional and product-strategic aspects for modularisation and enables the module requirements from different life phases to be included in the development of the module structure.…”

“…The Life Phase Modularisation combines technicalfunctional and product-strategic aspects for modularisation and enables the module requirements from different life phases to be included in the development of the module structure. A unique feature of Life Phases Modularisation is the Module Process Chart (MPC), which supports the identification of conflicts and contradictions between the module requirements of the individual life phases (Krause et al, 2014;Greve et al, 2020). So far, however, only tangible products have been modularised.…”

Product Service Systems (PSS) are increasingly important for companies. They enable a multitude of advantages, including the ability to offer customers even more individual customised solutions. However, PSS can also cause negative effects for companies. For example, PSS increase the complexity within companies. In order to cope with this complexity, the modularisation of PSS is frequently suggested in literature. However, existing approaches for modularisation only consider functional reasons for module composition and neglect the product-strategic aspects. This paper introduces a new approach for the modularisation of PSS, which combines functional and product-strategic aspects into one approach. To achieve this, a separate modular structure is developed for each life phase. Following this, these are harmonised across all life phases. This enables the advantages of the modular PSS structure to be used in all life phases. A PSS family of laser processing machines is used to illustrate the new developed approach.

“…Furthermore, these data are composed differently within the timeline of the in Figure 1 displayed modularization approach as well as within the individual methods used within the method steps as well, especially when it comes to the Life Phases After having analyzed the status quo, the PSS architecture undergoes the first step described by the Design for Variety [3] according to Kipp and Krause, where the complete architecture is strategically altered on its component level in order to enable the second step, which is the actual modularization itself. Within the Integrated PKT-Approach, the architecture is modularized for each life phase from Product Development to Recycling individually, leading to individual and therefore in some aspects differing modular concepts for each of these life phases [2,22,23]. In the following step, these differences are solved by an interactive discussion of the corresponding interdisciplinary expert team from each life phase.…”

“…This represents the second special feature of the approach. The representation in the MPC makes it possible to compare the modular structures of individual life phases with each other and to identify critical points and resolve conflicts [22,23,26] as shown in Figure 3. The network diagrams of the individual life phases are combined in the next step of the life phases modularization for PSS to form a so-called Module Process Chart (MPC).…”

Within emerging markets, ensuring the competitiveness of manufacturing companies is crucial to their success. The integration of new business possibilities, such as Product-Service-Systems (PSS) can provide one suitable solution. Especially within the architecture development process, large amounts of interconnected data and data types need to be processed and versioned. This leads to a significant lack of data consistency and continuity along the development process of modular PSS architectures. This lack of consistency and continuity leads to a process being prone to errors, representing a significant negative impact onto the company’s value-added stream. We provide one possible solution to these issues by presenting a PSS architecture modularization approach based upon the modularization methods of the Integrated PKT-Approach. Using concepts of Model-Based Systems Engineering (MBSE) for modelling these architectures, automated and dynamic analyses of the architecture for the iteration and harmonization of the PSS architecture under development are enabled. The at first generically described approach is further detailed in the second part of this contribution by applying it to an industry case study for mobile laser welding systems. As a result, a clear support for the visualization of architecture iteration aspects as well as for the enhancement of data consistency and continuity is given.
