You aren’t struggling to innovate due to lack of ideas. You probably have a database of hundreds (if not thousands) of ideas that you could commercialize. The dilemma is which of these multitude of ideas should you and your team actually pursue?
To answer this question, you need need a scientific, repeatable framework to understand which ideas have merit.
Bosch circular saw example. Segment of the market with underserved needs. Identified 12 features of a product that would directly address these needs. Had the team tried to innovate in the dark, what are the chances they would have created that product? Almost certainly 0% probability. However, once the needs were identified how long did it take them to design a product to meet the need? Only a few hours.
Flip innovation on its head – forget about solutions, start with needs, and come up with innovative ways to solve customer problems.
