Understanding Key Decision Making Tools: Brainstorming, Multivoting, and Nominal Group Technique
Decision making tools like brainstorming, multivoting, and the Nominal Group Technique (NGT) are fundamentals that every Certified Six Sigma Yellow Belt must understand and apply. These tools enhance team involvement, foster idea generation, and ensure that decisions are well-informed and consensus-driven—core principles aligned with Six Sigma’s DMAIC methodology.
Brainstorming is a popular technique used to generate a wide range of ideas from all team members without immediate critique or evaluation. This encourages creative thinking, allowing teams to explore many possibilities when identifying causes of problems or potential process improvements. It’s typically the first step in a decision-making process because of its inclusiveness and openness.
Multivoting helps in narrowing down ideas when a team is overwhelmed by too many options generated during brainstorming. It is a democratic and systematic way to prioritize ideas by having team members vote on their preferred options. This streamlines decision-making by focusing resources and attention on the most supported ideas.
The Nominal Group Technique (NGT) combines the benefits of brainstorming and voting but adds a structured process to avoid common pitfalls like dominance by vocal members or groupthink. In NGT, individuals first generate ideas silently, then present them to the group in a round-robin fashion, followed by discussion and prioritization through secret voting. This technique ensures balanced participation and results in a collective agreement on high-priority actions.
All three tools are vital topics in the CSSYB exam topics because they are practical, widely used in DMAIC projects, and critical to effective team-based problem solving.
Real-life example from Six Sigma Yellow Belt practice
Imagine you are a Certified Six Sigma Yellow Belt supporting a DMAIC project aimed at reducing customer wait times in a call center. Your team is tasked with identifying potential root causes of delays and must decide which causes to explore first.
First, you facilitate a brainstorming session where every team member, including frontline staff and supervisors, throws out all ideas—anything from technical issues with phone systems to staffing shortages. No criticism is allowed, encouraging even the less confident members to speak up.
After generating over 20 potential causes, the team uses multivoting to rank these ideas. Each team member gets a set number of votes and selects the causes they believe are most impactful. This quickly highlights the most critical areas for analysis.
Finally, to ensure no voices were overlooked and that priority decisions are well-balanced, you introduce the Nominal Group Technique. Each member writes down additional insights silently, then shares them sequentially. After further discussion, a private vote confirms which causes the team will address immediately. This structured approach reduces bias, makes decision-making transparent, and helps you move confidently into the Measure phase of DMAIC.

Question 2: How does multivoting help a Six Sigma team after brainstorming?
- A) It eliminates the least popular ideas by group debate
- B) It uses a structured silent writing phase to generate ideas
- C) It prioritizes ideas by allowing team members to vote for their favorites

Correct answer: C
Explanation: Multivoting is a democratic method that helps teams focus on the most relevant ideas by letting members vote on which ideas they feel are most important, thus streamlining the decision-making process.
Question 3: What distinguishes the Nominal Group Technique (NGT) from regular brainstorming?
- A) NGT eliminates all group discussion phases
- B) NGT includes silent idea generation, round-robin sharing, and secret voting
- C) NGT allows only managers to contribute ideas
- D) NGT uses technology for idea collection
Correct answer: B
