How to deal with Introvert or Extrovert Employee ? 5 step | Nominal group technique (NGT)

Say, you own a business and your team or staff consist of 6-8 employee. Psychologically, they all are recruited for same job or different job but their behavior differ from one another in many ways. 
Example being, one employee is frank, he/she love to express himself/herself or any thought. Another employee being introvert, they do have thought but they may speak or may not. Other employee may be shy, thinking, what would other think about me. While some, may put pressure on other employee with their thought. Really.. Yeah, many different behavior.

Step 3: The facilitator then requests an idea from each member in sequence. Each idea is recorded until ideas are exhausted. No discussion is allowed at this point.
Step 4: After the exhaustion of ideas, the clarification, support and evaluation of ideas is permitted. Comments on the ideas of others is encouraged
Step 5: Then Final Stage, Voting for best solution is then conducted. Several rounds of voting may be needed before a ‘best’ idea is found.
