Group decision making is an assessment process of multiple alternatives with an expected outcome in the form of future actions resolution. These can be used to generate, classify and prioritize requirements for the project.
There are multiple methods of reaching a group decision, for example:
• Unanimity. Everyone agrees on a single course of action.
• Majority. Support from more than 50% of the members of the group.
• Consensus. The majority defines a course of action, but the minority agrees to accept it.
• Plurality. The largest block in a group decides even if a majority is not achieved.
• Dictatorship. One individual makes the decision for the group.
Almost any of the decision methods described previously can be applied to the group techniques potentially used in the requirements gathering process.
