Explanation:

The differences among the three method of group decision making are:

INTERACTING GROUP: Enables team members or group to interact between each other thereby having an unstructed discussion of the problem in other to create solution. The group propose solution by actively debating about what the best decision making is.

DELPHI GROUP: Allows team members that are not physically in the same location to make decision about ideas or issues by using surveys to develop a final solution.

NOMINAL GROUP : Members or team do not discuss the issue and solution verbally. The group uses a written process to develop ideas in other to solve the problem.
