Agile development methodologies have been widely employed in the software industry, where they have been found to yield positive results. But can these new methods, with their new tools such as sprints, scrums, burndown charts, and backlogs, really be integrated with the traditional and popular Stage-Gate approach and then applied to physical products? Initial but limited evidence suggests yes: Larger IT firms have already integrated Agile and Stage-Gate and gained the benefits of both approaches; and most recently, a handful of manufacturing firms have employed this Agile-Stage-Gate hybrid model for physical new products. And if recent evidence can be trusted, this new approach promises to be the most significant change to our thinking about how new-product development should be done since the introduction of today's popular gating systems 30 years ago.
