2. Brainstorming Five to fifteen individuals
Discussion leader restates problem and reiterates rules of discussion
Individuals suggest ideas
Evaluate ideas at conclusion of discussion
Useful for new ideas / deadlock
Drawback: relies on willingness to speak up

4. Useful in systematic approach and large numbers of ideas
Six individuals
Useful in systematic approach and large numbers of ideas
Drawback: isolation, no group synergy

5. Suggestions are regrouped and returned to panelists
Resultant response list is reordered and evaluated
Expert panel generates starting points
Delphi Model
Suggestions are regrouped and returned to panelists
Polling process
Useful in situations where future of process is of concern
Drawback: relies on high response rate

6. Problem is presented to a small group
Group familiarizes itself with the problem
Synetics
Also utilizes variations such as randomly choosing words from a dictionary and forcing a fit
Analogies of terms are examined and relationships forced
Useful when problem to be solved has an analogy and group is willing to explore bizarre trains of thought

7. Class Design Example
Right to left heart shunt that needs to be closed – minimally invasive technology.
When doing catheterization, need to go with the flow…
Cannon droops when rapidly fired.
Need to get a ladder through a small space and up in an alleyway.
