## 4 Discussion  
The primary goal of this work was to find a way to help designers improve the manufacturability of their designs on RMS with an emphasis on micro-assembled, non-PCB products. Methods found in literature lacked several important aspects. The conceptual design as introduced by the SAPB is only part-centric and does not include processing issues. Therefore, it does not solve the \"over the wall\" problem of conceptual design. Other TDDs try to overcome those issues by adding more improved methods, but do not link them to the special needs of RMS and also do not show the ways that an implementation can happen. Methods based on the datum flow chain show little interest in an easy-to-use designer integration, only optimize the assembly sequence, and do not find possible machine configurations. OPM is useful to describe an assembly task, but lacks proper ways to be automated. MtM techniques can work around this issue, and with CPN, a method for RMS description exists. Still, modeling a product with objects and processes is not as accessible as modeling an assembly sequence. Beyond that, the OPM techniques do not include methods to work with non-determined product descriptions by the designer and do not give instructions on how to reach RMS solutions that fit the needs of process engineers and management. With the presented method and its implementation, an easy-to-use software tool could be introduced, with which designers could model simplified assembly sequences of their designs before the construction has been done. Designers obtain live feedback with which machine configurations of the selected RMS their assembly sequence model can be realized. Together with process engineers and the management, they can decide which machine configurations should be targeted. By this selection, a collection of properties for processes and components is set that can act as a combined working frame for a concurrent development of a product and process. This helps to avoid costly redesigns in the later product development phases and can be seen as a kind of dynamic guideline system. By setting targeted machine configurations, the utilization of RMS can be fostered, which decreases the investment risk of RMS. The basic requirement for a successful implementation is powerful and well defined databases. With the machine and the assembly database, the presented method showed the ways such databases could be generated. To prove the feasibility of the introduced method and the proposed implementation, PlaTooMA was developed as a use case. With a web based application and a state-of-the-art user interface that followed modern design principles, it had a low entry barrier and great accessibility. Following the method, relevant procedure types could be detected. With a selection of those procedures, fitting properties for components and processes were found. Constraint matrices for both property types were introduced that helped to exclude unsuitable procedure types and thereby helped designers

Several future improvements of the method, implementation, and use case are possible. No standardized modeling languages were used to describe the assembly sequence, the machine configurations, or the feature based description of machine parts and operations for the databases. This need not to be a disadvantage in every case. Especially the assembly sequence modeling benefited from being tailored to designer needs, had no strong ties to other systems, and may not be able to support the same degree of freedom, while still providing an automated analysis. However, describing machine parts and their features is often necessary for various situations and applications. With a standardized description or modeling language, the machine configurations would be reusable.
