Compare Agile and Waterfall Project Delivery for a Specific Context

You are choosing how to run a project and the agile-or-waterfall question is more religious war than help. This defines each approach plainly and weighs them against the realities of your situation, from someone who has watched both succeed and fail. For a working project manager who wants a decision, not a manifesto.

<context>
