|Introduction to Basic I-TRIZ|
Brainstorming, set forth in the 1950s by Alex Osborn, is governed by the following rules:
These rules are based on the notion that every person in the brainstorming group, and every idea generated, has equal worth.
Classical Brainstorming Drawback
Today, we know that brainstorming often falls short of expectations, yielding only a small number of mostly low-quality ideas. (A typical brainstorming session produces 10-15 wild ideas and 1-2 valuable ones.) The ineffectiveness of classical brainstorming can be illustrated by Pareto's law: Participants have fun and actively generate ideas for the first 20% of the session. The rest of the session is spent "squeezing" ideas out of the participants, who become bored and even irritated at having to withhold their opinions.
Ideation Brainstorming Process
The Ideation Brainstorming process integrates the brainstorming environment with a guided problem-solving method. I-TRIZ software acts as the "facilitator," providing a change of focus in the form of Tasks, as well as Directions and Operators that guide the problem-solver to the area of the solution space where the best solutions are likely to reside.
