Scope, schedule and cost are the three main constraints that government agencies often have in project implementation. Scope defines the goals, deliverables, and requirements of the project. Schedule defines the timeline, milestones, and dependencies of the project. Cost defines the budget, resources, and risks of the project. These three constraints are also known as the project management triangle or the triple constraint.
