Engineering Change Management Concepts for Systems Modeling
Conrad E. Bock, Allison Barnard Feeney
A significant cost of manufactured systems arises in changing system specifications after they have been built and delivered to customers. This might be due to errors in the original specifications, feedback from customers, competition from other producers, or new ideas for product improvement. It involves revisiting decisions and tasks that were considered completed, including modifying engineering specifications produced by these activities. This paper reviews engineering change management to understand the demands it places on system models and modeling languages, in particular the Systems Modeling Language.
