Failure to succeed at problem solving attempts however is under the control of individuals. Some reasons why a particular solution fails are
- No known solution
- Too expensive
- Too late
- Solutions backfire
Being too late to implement a problem solution is really a lack of vision and falls under failure to anticipate. If you have a good understanding of your process or system, then you shouldn't be caught with your pants down, unable to implement a solution in time.
Perhaps the most unforgivable reason for failure is solutions that backfire. By using the appropriate problem solving tools, in the right way, you will be able to implement solutions that will succeed. At the very least, you will be able to detect non-ideal solutions and design/fix the problems that occur. That is the heart of the DMAIC philosophy and the cycle of action. You must monitor any solution to insure it is (and continues to be) successful. Just because it worked the first time doesn't mean you can check it off your action item list and move on to the next problem. If that is happening, then I would suggest you are not truly a problem solver.
