In a world of Mass Customization, the role of change management cannot be denied. In the early days of manufacturing, each product often was an individual with individual blueprint. Consequently, a faulty design only had effect on few units. Nowadays, each problematic design (for example an electronic component) may cause problems to several different products, and the number of affected units may vary from tens to millions. The problems must therefore be processed efficiently to prevent waste – and Engineering Change Management (ECM) is one of the most important tools for that. Manufacturing companies handle a large number of engineering change requests every year. The number of ECRs produced varies as it depends, among other factors, on company size, product complexity and the extent of ECM use. The studies [1] [2] have shown that with complex products, the number of ECRs processed yearly may rise to thousands. A large number of ECRs leads to considerable amount of work: For each request, a separate document must be created, the document needs to be linked to related information, and then the document needs to be processed. If the evaluators decide that the request should advance further, the problem described in the ECR needs to be fixed. The actual re-design work will cause changes to documents that need to be delivered to all stakeholders (purchasing, manufacturing, spare parts, sub-contractors, etc.) The changes also sometimes start a “snowball effect” [3] of changes to surrounding parts/modules – and sometimes even to other products, hence increasing the work load even more.
