6. The Waterfall Model -Pros
Simple, manageable and easy to understand
Fits to common project management practices(milestones, deliverables etc.)
Focus on requirements and design at beginning, save money and time at the end
Can be suitable for short projects(some weeks)
Can be suitable for "stable" projects, where requirements do not change
Focus on documents, saves knowledge which can be reused by other people.
Widely used, e.g. US Department of Defense
Can be suitable for fixed-price contracts

7. The Waterfall Model -Cons
Software requirements change, hard to sign-off on a SRS.
Early commitment. Changes at the end, large impact.
Feed back is needed to understand a phase. E.g. implementation is needed to understand some design.
Difficult to estimate time and cost for the phases.
Handling risks are not part of the model. Pushes the risks forward.
