GAMBUSEGap Analysis Methodology for Business Service Engineering.

GAMBUSE consists of six different stages:

1. Creating meta-model instances for the as-is and to-be business process;

2. Identification and scoping of to-be functional fragments;

3. Distilling business services from the to-be process model;

4. Detecting and assessing the reusability of as-is systems;

5. Service Realization and Reusability strategy;

6. Creating Business Service Blueprints.
