Which project management approach may be appropriate for fixed requirements and timelines?

The Waterfall project management approach is particularly suited for fixed requirements and timelines. This methodology operates under a linear and sequential model where each phase must be completed before the next one begins. In scenarios where the project requirements are well-defined and unlikely to change, the Waterfall approach allows project managers to plan, schedule, and execute tasks with a clear understanding of the deliverables at every stage.

One of the primary advantages of Waterfall is its structured nature, which includes distinct phases such as requirements gathering, design, implementation, verification, and maintenance. This structure enables project teams to adhere to fixed timelines and budgets since there is less room for deviation once the project scope is defined. Consequently, if changes are required after the planning phase, it can lead to extended timelines and increased costs, making it less ideal for projects where flexibility is essential.

In contrast, other methodologies like Agile and Scrum emphasize adaptability to change and iterative progress, which might not align well with a project that requires fixed parameters. Lean Six Sigma, while effective in process improvement and efficiency, is more focused on minimizing waste and improving quality rather than strictly adhering to predetermined requirements and timelines.
