To be ‘innovations’ new ideas have to be acted upon. They have to implemented.   To be successful in turn that implementation has to be effective, and to be effective it should be based on a strategy. While not all successful innovators have based the implementation of their ideas on a written plan of action, it is highly recommended because unless an individual has the rare gift of a perfect memory and an uncluttered life it can be difficult to remember the detail of a plan and crucially to assess where one is in its implementation.
