Delphi Estimation in Crystal

Delphi Estimation is a technique used in Agile development, specifically in Crystal methodologies, to estimate the effort required for a project or task. It involves gathering input from a group of experts or stakeholders to reach a consensus on the estimated effort needed for a particular work item.

How it works:

1. Round-robin Feedback: Each expert provides an estimate independently in a structured round-robin manner.

2. Discussion and Iteration: Experts discuss the estimates and reasoning behind them, iterating on the estimates until a consensus is reached.

3. Consolidation: A final estimate is agreed upon by the group, often being an average or median of the individual estimates.

Advantages:

• Diverse Input: Involving multiple experts provides a range of perspectives and insights.
• Consensus Building: Helps in reaching a more accurate and well-rounded estimate through discussion and collaboration.
