Easy to manage due to the rigidity of the model – each phase has specific

Works well for smaller projects where requirement are very well understood

Top risk of the project

ID Top risk

1 We are behind schedule, and people are not spending enough time and dependencies are not defined. We don't finish on time everything that we have planned

2 Lack of human resources while doing projects.

3 There are lots of uncertainties in estimates; Estimates might be too large, and people might not work enough hours, or people spent more time than necessary.
