Interesting information on Delphi Technique

 

The Delphi Technique is a structured and systematic method for gathering and information from a group of experts or stakeholders to reach a consensus or make predictions about complex or uncertain issues. This can be used during requirements gathering, risk management etc. It is interesting to know about the two variations of Delphi technique.

➡ Delphi Technique

1️⃣ A way to reach a consensus of experts on a subject, experts on the subject participate in this technique anonymously
2️⃣ A facilitator uses a questionnaire to solicit ideas about the important points related to the subject
3️⃣ The responses are summarized and are then recirculated to the experts for further comments
4️⃣ Consensus may be reached in a few rounds of this process. This helps reduce bias in the data and keep any one person away from having undue influence on the outcome

➡ Wideband Delphi

1️⃣ Wideband Delphi is a variation of the Delphi estimating method where subject matter experts complete multiple rounds of producing estimates individually, with a project team discussion after each round, until a consensus is achieved
2️⃣ For Wideband Delphi, those who created the highest and lowest estimates explain their rationale, following which everyone estimates
3️⃣ The process repeats until convergence is achieved
4️⃣ Planning Poker is a variation of Wideband Delphi
