OMT Object Model
9.1 Process Model of Context
This model gives an overview of the context in which to place the technique of Object Diagram. This context is an iterative one. After each step in the procedure you have to look if the models you made before are still correct. If they are not correct you have to go back to an earlier stage. In this way the models refine after each step.
In this model only the most important input/output streams are modelled. We also assume that in every task the products of the preceding tasks are available.
