Requirements management Inception Identify stakeholders “who else do you think I should talk to?” Recognize multiple points of view Work toward collaboration The first questions Who is behind the request for this work? Who will use the solution? What will be the economic benefit of a successful solution Is there another source for the solution that you need? Eliciting Requirements meetings are .
