Why do requirements need analysis?

Business analysis information needs to be further decomposed to understand the information from the following perspectives:

• To ensure that everything that might need to change to meet the business needs has been noted and documented
• Similarly, to ensure that everything that should stay the same to meet the business needs remains intact
• To identify any missing components that are not yet included or specified
• To remove any unnecessary components
• To decompose and document any constraints or assumptions that have an impact on the components under analysis

By performing an analysis of the business analysis information, the business analyst provides a basis for discussion to enable the team to reach a conclusion about potential solution options.
