The deliverable is the most important factor that decides the success of a project. Hence, it is very important for a consultant to have a clear definition of the deliverable. A clear list of deliverables helps the consultant decide many more things, which can directly or indirectly impact the overall project delivery.

Requirement gathering helps the consultant get a fair idea about what needs to be delivered to the client. It may not be possible to have crystal clear deliverables in first attempt of every project, but continuous requirement gathering helps you to get closer to the desired deliverables. This also helps the clients to refine their requirements in such a way that they get maximum output from the project.
