Model Based Engineering of Specifications by Retrenching Partial Requirements
In conventional model oriented formal refinement, the abstract model is supposed to capture all the properties of interest in the system, in an as clutter-free as possible a manner. Subsequently, the refinement process guides development inexorably towards a faithful implementation. However refinement says nothing about how to obtain the abstract model in the first place. In reality developers experiment with prototype models and their refinements until a workable arrangement is discovered. Retrenchment is a formal technique intended to capture some of the informal approach to a refinable abstract model in a formal manner that will integrate with refinement. This is in order that the benefits of a formal approach can migrate further up the development hierarchy. After a presentation of the basic ideas of retrenchment, a simple telephone system feature interaction case study is given to illustrate how retrenchment can relate incompatible partial models to a more definitive consolidated model during the development of the contracted specification.

Abstract
In conventional model oriented formal refinement, the abstract model is supposed to capture all the properties of interest in the system, in an as clutter-free as possible a manner. Subsequently, the refinement process guides development inexorably towards a faithful implementation. However refinement says nothing about how to obtain the abstract model in the first place. In reality developers experiment with prototype models and their refinements until a workable arrangement is discovered. Retrenchment is a formal technique intended to capture some of the informal approach to a refinable abstract model in a formal manner that will integrate with refinement. This is in order that the benefits of a formal approach can migrate further up the development hierarchy. After a presentation of the basic ideas of retrenchment, a simple telephone system feature interaction case study is given to illustrate how retrenchment can relate incompatible partial models to a more definitive consolidated model during the development of the contracted specification.
