Forrester blog has a post on Invention, innovation, and product management that is defeinity worth the read.
Innovation is a messy, difficult, strenuous, and time consuming process. With a good product manager, there are opportunities to be the voice of the customer during the iterations that can greatly improve the chances that a compelling product will emerge:
- Develop target customers
- Increase/decrease scope
- Fine tune feature requirements/priorities
- Gather feedback/support from key internal/external decision makers
One the flip side, when it is time to pull the plug, product managers can help make the call before its too late (as in, too much time/money/reputation has been invested).
