Delphi Estimation in the context of Crystal
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:
Round-robin Feedback: Each expert provides an estimate independently in a structured round-robin manner.
Discussion and Iteration: Experts discuss the estimates and reasoning behind them, iterating on the estimates until a consensus is reached.
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.
