Constraint
Official Definition:
A limitation that the project must work within (e.g., fixed deadline, budget or resources).
Layman’s Definition:
Constraints are the “must not cross” lines for the project — things like deadlines, budgets or rules that can’t be broken.
Examples:
• Construction: Must complete bridge works before the school year starts.
• Tech: Project must use existing IT systems due to licensing limits.
• Healthcare: Only £300,000 is available in this financial year.
When to Use:
Constraints must be identified when planning the project and reviewed regularly to make sure they’re not being breached.
