Defining the business need is the activity that Henry is asking Janet to complete. Defining the business need is the process of identifying and describing the problem or opportunity that the organization faces and how it aligns with the organizational goals and objectives. It helps to set the direction and scope for the rest of the business analysis activities and to justify the initiation of a project or an initiative. Defining the business need is part of the strategy analysis knowledge area in the CCBA certification12

Option A is incorrect because brainstorming the business need is not an activity, but a technique. Brainstorming is a technique that involves generating and evaluating new and original ideas to address a problem or an opportunity. It can be used as part of defining the business need, but it is not the same as defining the business need34

Option B is incorrect because creating a data diagram for the service is not an activity, but a deliverable. A data diagram is a graphical representation of the data and information that are relevant to the solution. It can be used as an output of defining the business need, but it is not the same as defining the business need.

Option D is incorrect because eliciting the requirements of the proposal is not an activity, but a process. Eliciting the requirements is the process of identifying and obtaining the information needed from the stakeholders and other sources to define and validate the requirements. It can be used as an input to defining the business need, but it is not the same as defining the business need.
