Even during ramp-up phases technical product changes are inevitable. Swift and spontaneous reaction is therefore required for meeting the set market entry date. At the same time, risk estimation of different solution alternatives is needed to evaluate the effects of product changes on product and processes. In this context unstructured procedures observed in practice lead to unsatisfactory solutions and unforeseeable effects. This dilemma of product change management has been countered with the development of PMEA (Product Change Mode and Effect Analysis) and its combination with TRIZ (Theory of Inventive Problem Solving).
