Questions & Answers

Q: What is the Iron Triangle in project management?

The Iron Triangle is a concept that represents the trade-offs between time, cost, and quality in project management. It helps project managers understand the constraints they face when making decisions.

Q: How are the three corners of the Iron Triangle defined?

The three corners of the Iron Triangle are time/schedule, cost/budget/resources, and quality/functionality. These factors are interconnected and influence each other in project planning and execution.

Q: Why is the Iron Triangle also known as the Triangle of Balance?

The Iron Triangle is often referred to as the Triangle of Balance because once the time, cost, and quality/functionality corners are locked together, they create a balanced plan. Changing one corner requires adjustments to maintain balance.

Q: How does the Iron Triangle constrain project managers?

The Iron Triangle imposes constraints on project managers because changing one corner, such as increasing quality, requires adjustments in at least one other corner, such as increased cost or longer time. The trade-offs need to be carefully managed.

Summary & Key Takeaways

• The Iron Triangle is a representation of the competing pressures to produce the best results quickly and at minimum cost.

• The three corners of the Iron Triangle are time/schedule, cost/budget/resources, and quality/functionality.

• Once the three corners are locked together, changing one corner requires adjusting at least one other.
