Technical Note 3 continues the research on CARISMA with the topic Analysis of the Process Chain for Cabin Conversions, undertaken within a Completion Center. Based on the original research structure, defined in the research implementation, several topics were added and others were considered with special attention. The analysis focused rather on the analysis of the current capabilities of ELAN, while the vision Completion Center presented secondary importance. Two basic directions were investigated: First, the process chain identified in TN 1 was analyzed using Dependency and Structure Modeling tools, such as Design Structure Matrix. This delivered the optimal sequence of the processes within the process chain. In the same time it allowed the selection of the most important ones. Second, a case study approach was used to identify the required input information when cabin conversions are planned for non-Airbus customers. In order to perform this investigation, the available engineering input information sources were identified. This topic presented special interest for ELAN. The results confirmed that small conversions can currently be conducted at ELAN with the available resources.
