According to the BABOK® Guide, the plan business analysis activities process is the process of defining the tasks, dependencies, effort, and schedule for the business analysis work. The four inputs to this process are:
Stakeholder list, roles, and responsibilities: This input provides information about the stakeholders who are involved in or affected by the business analysis work, their roles and responsibilities, their communication preferences, and their availability.
Organizational process assets: This input provides information about the policies, procedures, standards, guidelines, and templates that are relevant to the business analysis work, such as the project management methodology, the business analysis methodology, the requirements management plan, and the change management plan.
Business analysis approach: This input provides information about the selected method and level of detail for performing the business analysis work, such as the plan-driven, change-driven, or hybrid approach, and the level of abstraction, formality, and rigor of the requirements and designs.
Business analysis performance assessment: This input provides information about the current state and desired state of the business analysis performance, such as the strengths, weaknesses, opportunities, and threats of the business analysis work, the performance indicators and measures, and the improvement actions and recommendations.
A list of identified risks is not an input to the plan business analysis activities process, but rather an output of the identify risks process, which is a sub-process of the plan business analysis approach process. A list of identified risks provides information about the potential threats or uncertainties that could affect the business analysis work, such as the assumptions, constraints, dependencies, issues, and changes.
