The document discusses the phases of a fixed-cost project, including pre-sale, planning, implementation, and finishing. In the pre-sale phase, it is important to understand customer needs, estimate the project scope and costs accurately accounting for risks and uncertainties. During planning, communication with the customer and a change request process should be defined. In implementation, risks are reviewed and any small changes or change requests are managed. Finally, acceptance criteria are confirmed, maintenance options discussed, and lessons learned captured. Using some Scrum practices like sprints and daily stand-ups can help manage fixed-cost projects.
