To identify the requirements and to define the objectives in process chain evaluation, a special procedure is followed. Firstly 17 interviews were carried out in different departments along the complete product life cycle. The interviews were used to filter out the requirements of the MTU in general and of the different departments in detail. From this, about 65 requirements could be generated. Then all specified requirements were transformed into formulated objectives. In defining these objectives, the “SMART-rule” was applied. The results of the objective definition were 38 formulated objectives. To make this quantity manageable the objectives were prioritised, followed by a classification.

The following two diagrams illustrate the surveyed requirements and derived objectives and their characteristics.
