Which trio is commonly referred to as the triple constraints in project management?

• A. Scope, Time, Cost
• B. Scope, Time, Resources
• C. Time, Cost, Quality
• D. Cost, Schedule, Resources

Answer: (A)

In project management, three interconnected factors drive how a project is planned and delivered: the scope of work, the time available (schedule), and the budget (cost). These form the triple constraints because changing one inevitably impacts the others. For example, expanding the scope adds more work, which usually requires more time and higher cost; shortening the schedule often means either sacrificing scope or spending more to accelerate work; and reducing the budget can force you to scale back scope or extend the timeline. So, the trio referred to as the triple constraints is scope, time (schedule), and cost (budget). Other elements like resources or quality matter in project outcomes, but they are not the classic three constraints.
