Role of BA in the system development life cycle

Role of BA in the system development life cycle

The BA plays a central role in the system development life cycle (SDLC). In general terms, the SDLC contains well-defined phases which are executed by the project team:

• A business idea or request,
• Feasibility (business case)
• Planning (business requirements, functional requirements)
• Delivery (Coding, execution of activities)
• Testing (test cases, unit testing, integration testing, user acceptance testing)
• Implementation (roll out of the idea or request)
• Close out (documentation, post implementation review)

This is also known as project methodology. A version of the SDLC is part of many different Project Methodologies such as RAD, SDM, Rational Unified Process.

The BA will provide different services during the SDLC:

• Assisting with the Business case
• High level feasibility
• Gathering of the requirements
• Designing and/or reviewing test cases
• Processing change requests
• Tracing the requirements during implementation (traceability matrix).
• Manage scope
• Acceptance, Installation, deployment
