Final answer:
The step 'Problem resolution and follow up' is NOT a part of the nominal group technique in brainstorming, as it focuses on idea generation and prioritizing solutions. The correct answer is option c.
Step-by-step explanation:
The step that is NOT a key part of the nominal group technique (NGT) in brainstorming is 'c. Problem resolution and follow up'. Nominal group technique, a structured form of brainstorming, is a process consisting mainly of the following steps: 'a. Individual idea generation', 'b. Problem identification and definition', 'd. Solution generation', and 'e. Decision making'.
These steps ensure a systematic approach to idea generation and decision making. The process does not typically include a formal problem resolution and follow up as part of its immediate procedure, as NGT focuses primarily on the generation and prioritization of solutions.
Steps such as resolution and follow-up are generally parts of the implementation phase that occurs after the brainstorming and decision-making process.
