Group decision-making techniques
“Group Decision-Making Techniques” is a tool/technique for the process “Collect Requirements”.
A group decision-making technique is an assessment process having multiple alternatives with an expected outcome in the form of future actions. These techniques can be used to generate, classify, and prioritize product requirements.
There are various methods of reaching a group decision, such as: – Unanimity. A decision that is reached whereby everyone agrees on a single course of action. One way to reach unanimity is the Delphi technique, in which a selected group of experts answers questionnaires and provides feedback regarding the responses from each round of requirements gathering. The responses
are only available to the facilitator to maintain anonymity.
– Majority. A decision that is reached with support obtained from more than 50 % of the members of the group. Having a group size with an uneven number of participants can ensure that a decision will be
reached, rather than resulting in a tie.
– Plurality. A decision that is reached whereby the largest block in a group decides, even if a majority is
not achieved. This method is generally used when the number of options nominated is more than two.
– Dictatorship. In this method, one individual makes the decision for the group.
All of these group decision-making techniques can be applied to the group creativity techniques used in the Collect Requirements process.
“Group Decision-Making Techniques” is a tool/technique for the process “Validate Scope”.

“Group Decision-Making Techniques” is a tool/technique for the process “Estimate Activity Durations”.
Team-based approaches, such as brainstorming, the Delphi or nominal group techniques, are useful for engaging team members to improve estimate accuracy and commitment to the emerging estimates. By involving a structured group of people who are close to the technical execution of work in the estimation process, additional information is gained and more accurate estimates obtained. Additionally, when people are involved in the estimation process, their commitment towards meeting the resulting estimates increases.
