Team members anonymously estimate story sizes in several rounds, with feedback and discussion between each round. As the group shares knowledge and narrows the range of estimates, the resulting consensus tends to be more accurate than individual estimates. The method highlights differing perspectives and leverages group wisdom. It focuses on overcoming estimation biases, encourages input from all team members, and fosters better understanding of requirements by identifying risks and unidentified activities.
Guide to Wideband Delphi
Why it is important: Wideband Delphi is important because it improves estimation accuracy by leveraging the collective wisdom of the team. It mitigates the risk of under or over-estimation, which are common challenges in project management, particularly in agile environments.
What it is: Wideband Delphi is an estimation technique used in project management. It is an expert judgement method that includes a team of experts that make estimates anonymously. It is based on the Delphi estimation Technique but uses a wider communication band for feedback.
How it works: Wideband Delphi works by iterating estimation sessions. The team of experts provide estimates, and then they discuss the estimates. Any variations in estimates are studied and adjusted in further rounds until a consensus is reached or the variations are reasonably minimal.
Exam Tips on Answering Questions on Wideband Delphi: When answering questions about Wideband Delphi in an exam, it is important to highlight that the estimates are done anonymously to prevent influence, mention the iterative nature of the process until consensus and always clarify that it is a form of expert judgement.
