The primary role of business modelling is mostly during inception stage and elaboration stages of project and it fades during the construction and transitioning stage. It is mostly to do with analytical aspects of business combined with technical mapping of the application or software solution.

●      Domain and User variation − Developing a business model will frequently reveal areas of disagreement or confusion between stakeholders. The Business Analyst will need to document the following variations in the as-is model.

●      Multiple work units perform the same function − Document the variances in the AS-IS model. This may be different divisions or geographies.

●      Multiples users perform the same work − Different stakeholders may do similar work differently. The variation may be the result of different skill sets and approaches of different business units or the result of differing needs of external stakeholders serviced by the enterprise. Document the variances in the AS-IS model.

●      Resolution Mechanism − The Business Analyst should document whether the ToBe solution will accommodate the inconsistencies in the current business model or whether the solution will require standardization. Stakeholders need to determine which approach to follow. The To-Be model will reflect their decision.
