The triple constraint in project management refers to the three interdependent variables that limit a project: scope, time, and cost.

The triple constraint in project management refers to the three interdependent variables that limit a project: scope, time, and cost.

• Scope defines the features and functions of the project's deliverables.
• Time refers to the schedule for completing the project.
• Cost is the budget allocated for the project.

These three elements are interconnected; a change in one will inevitably affect the other two. For example, increasing the project scope (more features) will likely increase both the time and cost required. Similarly, reducing the project's timeline might necessitate reducing the scope or increasing the cost to expedite work.
