The Triangle of Project Execution

Scope, Timeline, and Resources

This triangle represents the core trade-offs in any project. You’ve likely heard the phrase: “You can pick two, but you can’t have all three.” It’s true—these three elements form a delicate balance.

1. Scope: What will be done? Scope defines the project’s size, goals, and deliverables. Expanding scope increases complexity and often demands more time or resources.

2. Timeline: When will it be done? Deadlines drive urgency but come with constraints. Shorter timelines may compromise scope or demand additional resources.

3. Resources: What’s available to get it done? Resources include budget, people, and tools. Limited resources require sacrifices in scope or timeline.

The triangle teaches us a simple truth: you can’t maximize all three simultaneously. Prioritize two, and the third must flex. Understanding this balance helps manage expectations, allocate effort, and deliver successful outcomes.
