IDEA: Do not toss out ideas: review all submitted suggestions/ideas a second time with a different review group.

Do not discard ideas just because they fail the first evaluation committee. Try interviewing the person who submitted the idea because it may have been written poorly but still retains a great concept or idea for the company. If it is rejected by the first evaluation committee, the people on that first group are good at certain things but may not be creative.  Not all people understand the potential and promise of new ideas and concepts.  Keep the rejected suggestions your employees, vendors and visitors contributed and give them to a second group of people with different backgrounds (i.e. QC, engineering, marketing, sales representatives). Let them consider the ideas again and rethink further options.  If you must, hold them for a few months and then throw them back in front of another evaluation group.
