There are many times in an engagement when a business analyst has to create organization.
This could be organizing requirements, test cases, test results, client feedback, etcetera.
When there are many items to be organized, the lack of organization could potentially lead to a significant increase in effort required.
If requirements are not organized, requirements and approval may start going in circles.
If testing is not organized, the effort required to complete testing can grow exponentially.
If client feedback is not organized, change management may increase in effort.
Understanding and awareness are powerful tools that are fed by organized information.
