To execute a project successfully, the project manager MUST balance which three competing factors?

Project management principles emphasize balancing scope, time, and cost, often referred to as the project management “triple constraint” or “iron triangle.”

Scope defines the work required to complete the project successfully, including deliverables, system specifications, and operational objectives.

Time represents the project schedule and deadlines for completing tasks, phases, or milestones.

Cost encompasses budgetary limits, including labor, materials, equipment, and contingencies.

A project manager must continuously monitor and adjust these factors to ensure that changes in one area do not negatively impact the others. For example, expanding scope without adjusting time or cost can jeopardize project success. This approach aligns with PSP guidance for security system projects, where maintaining balance among scope, schedule, and budget is critical to delivering an effective and operationally viable security system.
