In strategic projects, which best describes the triple constraints of scope, time, and cost?

• A. Time defines horizon and urgency.
• B. Cost defines resource limitations.
• C. Scope defines breadth of the initiative; time defines horizon and urgency; cost defines resource limitations.
• D. Scope defines urgency; time defines resource limitations; cost defines market demand.

Answer: (C)

The main idea here is how the three constraints—scope, time, and cost—define what a project can deliver and how it’s delivered. Scope defines the breadth of the work—the features, deliverables, and boundaries of what’s included. Time sets the project’s horizon and urgency—the schedule, deadlines, and pace of progress. Cost represents the resources available—the budget and other financial limits that constrain what can be done.

The correct description matches each constraint to its actual role: scope determines what will be delivered, time determines how long it will take and how urgent the delivery is, and cost determines how much resources you can spend. In strategic projects, these stay tied together: expanding scope usually requires more time and/or more money, while shortening time or cutting cost often forces a reduced scope or additional resources.

The other options fall short because they fixate on only one aspect or mix up the roles—for example, treating time as the sole horizon, or cost as the sole resource, or misattributing urgency and market demand.
