The business analysis approach is the methodology and process that will be used to conduct business analysis activities and deliver business analysis outputs. The business analysis approach can be either plan-driven or change-driven, depending on the nature and context of the project. A plan-driven approach is a predictive methodology that follows a sequential and structured process, where the requirements and the solution are fully defined before implementation begins. A change-driven approach is an adaptive methodology that follows an iterative and flexible process, where the requirements and the solution are continuously refined and validated through feedback and collaboration1
The primary inputs to the business analysis approach are:
Organizational process assets: These are the policies, procedures, standards, templates, and tools that are available within the organization and that can influence the selection and execution of the business analysis approach. For example, the organization may have a preferred or mandated methodology, a set of best practices, or a repository of historical data that can guide the business analysis activities2
Expert judgement: This is the knowledge and experience of subject matter experts who can provide guidance and recommendations on the most suitable business analysis approach for the project. For example, the experts may include senior business analysts, project managers, stakeholders, or external consultants who have expertise in the domain, the industry, the technology, or the methodology3
Business need: This is the problem or opportunity that the project aims to address. It defines the gap between the current and desired states of the organization and its capabilities. The business need can influence the choice of the business analysis approach based on factors such as the urgency, complexity, uncertainty, and value of the need4
Penalty of not seizing the opportunity: This is the potential loss or risk that the organization may incur if the project fails to deliver the expected benefits or outcomes. It reflects the importance and priority of the project for the organization and its stakeholders. The penalty of not seizing the opportunity can influence the choice of the business analysis approach based on factors such as the scope, quality, cost, and time of the project.
