Why is tailoring in a project necessary?

Tailoring is necessary because requirements evolve and change throughout the project lifecycle, requiring the project manager to adapt methodologies, processes, and tools to remain aligned with current project needs. A static approach cannot adequately address the shifting demands of a project environment, making continuous tailoring essential for effective delivery.

The requirement to produce an artifact is a project deliverable consideration, not a reason tailoring itself is necessary across a project.

The need for a specific tool or technique is a situational decision within a process, not the foundational reason why tailoring as a discipline is necessary.

While project uniqueness is often cited as a context for tailoring, the question identifies changing requirements as the primary driver that makes ongoing tailoring within a project necessary.
