This is one of the most important phases of the business analysis process. It is
absolutely critical that the business analyst gathers the business requirements
accurately before defining a software solution.
To effectively gather requirements, the business analyst must assess the type of
the project, the people involved and the volume of information required.
Some of the techniques that he can use are:
Interviews with stakeholders
Facilitated information gathering sessions
Surveys and questionnaires
Observation of stakeholders performing their tasks
Study of existing systems and documentation
Gathering requirements is an iterative process. In addition to identifying the requirements,
the business analyst also needs to prioritize them to ensure that the most critical
issues are addressed first.
