The BABOK Knowledge Areas define categories of related information and tasks that a business analyst must understand and apply.

Knowledge areas do not necessarily represent, or need to align with, phases of a project.  There is no specific order in which tasks from various knowledge areas must be performed by the business analyst, as long as the necessary inputs for each task have been completed and are available.  The seven knowledge areas are:

1. Business Analysis Planning and Monitoring
   
2. Elicitation
   
3. Enterprise Analysis
   
4. Requirements Analysis
   
5. Solution Assessment and Validation
   
6. Requirements Management and Communication
   
7. Underlying Competencies
