Should we kill underperforming innovation projects sooner?
Yes, innovation projects should be stopped, reshaped or retested sooner when rapid tests show that their core assumptions do not hold. The goal is not to punish failure. It is to avoid spending more time and money defending an idea that is not becoming commercially viable.
A useful approach is to test ideas early, learn from what does not work and iterate towards a stronger option. This is intelligent failing: treating failed assumptions as useful information rather than a reason to hide the result. Teams still need space to imagine freely, but imagination needs action. A clear test-and-learn rhythm helps leaders make better decisions before an idea becomes an expensive commitment.
