Feedback mechanism
Data generat
or
Data use
1. Data control and validation versus reference
2. Evaluation versus requirements
3. Improvements versus technology
1. automatically? part of control, automatic pre-validation & control
2. Manually by the operator *3. R&D project

choice
1 data & warning, rather automatically, the easy way
e.g. on-line via desktop
2 data & application, manually, help yourselfe.g. by XLS macro
