Spiral Development makes Stage-Gate® a much more adaptable development process, one that is particularly well-suited to innovative new products, and one that adapts to changing, uncertain market conditions. Build in the concept of spiral or agile development, allowing project teams to move rapidly to a finalized product design through a series of “build-test-feedback-and-revise” iterations. Customers or users really don’t know what they want until they see it, especially in case of very innovative products. So get something in front of the user, fast – something the customer can see, feel, touch, and respond to.
