KIN has often recommended, and used, the 'destructive testing' approach to achieving change - taking an idea and finding as many ways as possible to ensure the desired outcome is not achieved. As well as being much more fun than trying to find 'the right solution', this allows effective mitigations to be developed.
I highly recommend this article in McKinsey Quarterly 'Battle Test Your Innovation Strategy' which suggests using 'war-gaming' as an alternative approach to innovation development. This is similar to the destructive testing technique, but helps in scenario planning and may aid the development of alternative ideas or the canning of non-viable ones.
