The document discusses the 'iron triangle' of project management, which highlights the constraints of scope, time, quality, and cost in project execution. It emphasizes the trade-offs involved when adjusting one element affects the others, particularly in relation to client expectations and team skills. Additionally, it outlines the need for compromise and prioritization of project features, while addressing the risks associated with internal and external changes over time.

- 2. 2 Iron Triangle Constraints Scope TimeQuality The Iron Triangle relates constraints in a Project between:
- 3. 3 Iron Triangle Constraints Scope TimeQuality The Iron Triangle relates constraints in a Project between: The common use place Cost here, but we will use Quality We can measure cost easily but to measure quality is really harder But because we can’t measure quality we can’t drop it A larger scope will need more time If we have limited time we will reduce Scope o lessen Quality

- 5. 5 Iron Triangle Scope TimeQuality Cost Expectations Skills The constraints relates nodes by triangles sides Constraints S Q T Moving along this side we can favor Quality or Time, and all depends on expectations our client have Expectations to high, high quality demanded that will need more Time (more Money) No Time: We can lessen Scope or we can lessen Quality, (or both), (or try to reason with Client) 1
