Which of the following is NOT one of the 6 services identified in the Business...

The Business Analysis Service Framework (BASF) identifies six core services provided by a business analyst. These services span the lifecycle of a business change initiative and focus on analysis and enablement activities. The six services are: Situation Investigation and Problem Analysis, Feasibility Assessment and Business Case Development, Business Process Improvement, Requirements Definition, Requirements Management, and Business Change Deployment. The service Solution design and development (which involves the technical building of the IT system) is a distinct project activity typically performed by solution architects and developers and, while the BA collaborates with them closely, it is not one of the core Business Analysis services as defined in the BASF.
