Brainstorming Techniques for Group and Individual Idea Generation

PMBOK v8 Definition

Brainstorming is a technique used to gather data and solutions or ideas from stakeholders, subject matter experts, and team members. It is conducted in a group environment led by a facilitator and comprises two parts: idea generation and analysis. Brainstorming techniques include brain-netting (virtual brainstorming using digital collaboration platforms), individual brainstorming (free writing, word association, spiderwebs), mind mapping, reverse brainstorming, round-robin, starbursting, and SWOT analysis.

Why It Matters for the Exam

Brainstorming appears frequently on the PMI exam in questions about data gathering techniques, stakeholder engagement, and risk identification. You will see it tested in situational questions where the project manager needs to generate creative solutions, identify risks, or engage team members in problem-solving-often asking you to select the correct brainstorming variant for a specific scenario.

Key Points to Remember (for the exam)

• Two Parts of Brainstorming: Idea generation (first) and analysis (second)-never skip the analysis phase.
• Facilitator Required: Group brainstorming must be led by a facilitator; individual brainstorming does not require one.
• Brain-Netting: Virtual brainstorming using digital collaboration platforms; allows anonymous idea sharing.
• Individual Brainstorming Techniques: Free writing (time-based, ignore grammar/spelling), word association (create word lists related to topic), spiderwebs (visual note-taking diagramming thought processes).
• Reverse Brainstorming: Team creates ideas about how to make a problem worse instead of solving it-helps identify root causes.
• Round-Robin: Everyone on the team takes a turn to generate and develop ideas-ensures equal participation.
• Starbursting: Creates a list of questions from six angles: who, what, when, where, why, and how.

Typical PMI Exam Example

A project manager is facilitating a risk identification workshop with stakeholders who are hesitant to share ideas openly. The team is distributed across three time zones. Which brainstorming technique should the project manager use? Answer: Brain-netting (virtual brainstorming with anonymous idea sharing).

PMI Exam Traps

• Trap: Confusing brainstorming with mind mapping → Reality: Brainstorming generates ideas; mind mapping consolidates ideas created through individual brainstorming sessions into a single map.
• Trap: Thinking brainstorming is only a group activity → Reality: Individual brainstorming (free writing, word association, spiderwebs) is also a valid technique.
• Trap: Believing reverse brainstorming solves the problem directly → Reality: Reverse brainstorming makes the problem worse to identify root causes-it does not produce solutions directly.
• Trap: Confusing round-robin with starbursting → Reality: Round-robin gives each person a turn to generate ideas; starbursting creates questions (who, what, when, where, why, how) about an idea.
