Brainstroming works best with people of varied specialties for less complicated products according to Stylianos Kavadias and Svenja C. Sommer journal of the Institute for Operations Research and the Management Sciences (INFORMS).
When developing highly technical products specialists working in private or in collaborative 'nominal' groups work best.
The study "The Effects of Problem Structure and Team Diversity on Brainstorming Effectiveness" HEC Paris.
From the 1950’s a a lot has been written about successful brainstorming sessions, However, social psychology researchers have long insisted that brainstorming groups perform worse than an equal number of isolated individuals.
The present study tried to bridge the lack of consensus.
The study concluded that that nominal groups perform better in specialized problems, even when the factors that affect the solution quality have greater problem complexity.
However, inn cross-functional problems, the brainstorming group exploits the competence diversity of its participants to attain better solutions.
