The more able you

23、 are to focus on a specific attribute, the more likely you are to think flexibly and discover alternative ideas.How To1.State your challenge2.Analyze the challenge and list as many attributes as you can3.Take each attribute, one at a time, and try thinking of ways to change or improve it. Ask “How e

To find a solution, he listed the attributes of a fish including:Lives under waterHas gills and finsConstantly moves to escape predatorsCold-bloodedChanges color out of waterHe looked at each attribute separately, trying to find ideas to

26、solve his problem. Finally he hit upon the solution: He put a small shark in the tank with the fish. The fish kept moving to escape being eaten and retained their vitality and thus their fresh flavor. Considering the attribute of predators enabled him to find his solution.18More Involved Creativity

30、to Better SolutionsIn order to get better solutions, we will follow these steps: Generate Criteria Weight Criteria Evaluate IdeasThe tool we will use for this is the Solution Prioritization Matrix.SolutionABCD0.21.250.31.650.6EasyQuickTechHi Impact CustomersSUM2.63.02.42.719.88.258.44.81013.7543.61.

As a starting point, here is a checklist of common criteria used to evaluate proposed changes or solutions.Which root causes are attacked, and to what extent?

32、What is the cost?What are the potential benefits?How easy will this be to implement?What are the potential problems?How easy will it be to prevent or remedy side effects?27Weighting the CriteriaNot all criteria are created equalYou need to decide which criteria are most important for your projectOne

33、 approach for developing weights is to have team members vote28How to Weight CriteriaUse consensus or a “multivoting” approach to narrow the list of criteria to 10 or fewerRank the remaining criteriaCriteriaA.
