Explanation
A plan-driven approach to business analysis is a methodology that focuses on minimizing up-front uncertainty and ensuring that the solution is fully defined before implementation begins in order to maximize control and minimize risk. This approach tends to be preferred in situations where requirements are stable and clear, and where changes are costly and disruptive. Therefore, changes in the plan-driven approach are generally avoided unless they are genuinely necessary to address a significant issue or opportunity. Changes in the plan-driven approach require formal approval and documentation, and may affect the scope, schedule, budget, and quality of the project. Changes in the plan-driven approach should be carefully analyzed and justified before being implemented123.
