According to the PMBOK® Guide, Tailoring is a necessary element of project management because every project is unique; not every process, tool, technique, input, or output identified in the standard is required on every project.

Definition: Tailoring is the deliberate adaptation of the selected project management processes, inputs, tools, techniques, outputs, and life cycle phases to create a management approach that is appropriate for the specific project environment and the work at hand.

The Project Manager ' s Role: The project manager, in collaboration with the project team, sponsor, or organizational governance, is responsible for tailoring. They must decide what is necessary to manage the project effectively without adding unnecessary " bureaucracy " or " overhead. "

Factors for Tailoring: When tailoring, the project manager considers:

Project size and complexity.

Organizational culture and governance.

Stakeholder needs.

Regulatory and safety requirements.

The project’s physical location.

D. Adjustment of the respective influences...: This describes the management of the Triple Constraint (Scope, Schedule, Cost/Quality). While related to decision-making, it does not define the systemic " tailoring " of the project management methodology itself.
