Abstract
The development and manufacturing of high-precision micro-mechatronic systems (MMS) is a challenging task, and the high demand for individualized products complicates the engineering design process (EDP) in particular. The established EDP for MMS is not designed for individualized products. This article gives an overview of the challenges (critical factors) in product development and manufacturing of individualized MMS (iMMS), a novel definition of iMMS, and describes a new qualitative methodology in order to tailor an EDP based on use cases, so-called “Tailored EDP-Methodology” (TEDP-Methodology). This TEDP-Methodology allows creating use-case-based product groups through the abstraction of the use cases and evaluating the requirements, which is essential to tailor or develop a new EDP. For the development of this new approach, a literature review and qualitative content analysis are prefaced. The TEDP-Methodology is critically examined and validated with a real case study for the development and manufacturing of an iMMS. This study shows critical points within the EDP. It shows fields of action for innovative tools to support the development process of iMMS and requirements for different product groups within iMMS. This article has both theoretical and practical implications.

This is the reason why each use case has to be attributed to a different product group, and no group of use cases within the same product group has emerged from this study
Summary
This section shall highlight the relevance of MMS and/or iMMS and explain its suitable technologies and the necessity for new methodological approaches for iMMS (Section 1.1). Micro-mechatronic systems (MMS) are key enabling technologies for the development of smart products, such as intelligent telephones, intelligent sensors for machines and plants or micro robots. These only represent a very small selection of such applications [4]. The increasing demand for individualization poses great challenges to the engineering of MMS, as the entire MMS manufacturing process is based on the concept of large-scale production [7]. To ensure cost-efficient and individualized MID production, one approach is to redesign established process chains and use digital process chains such as additive manufacturing technologies [14]. To meet the requirements such as time, cost and quality, development methods and adapted development processes can help achieve the requirements
