Read the article (Stage-Gate Idea to Launch Model Overview) . It explains the basic Stage-Gate innovation process used in product development. "Stage Gate" is a proprietary name/model for the generically labeled "phase-gate process." This article comes from Stage-Gate International, a consulting company. You should not expect a neutral, detached perspective from them. Their model has been widely used, enough that people often don't realize the difference between a generic phase-gate approach and their Stage-Gate model. Truth be told, there aren't many real differences except that their label is proprietary. Others have their own versions.

A traditional Stage-Gate process would be more effective in helping a company recognize and successfully implement which type of innovation as defined by Clayton Christensen, a sustaining innovation or a potentially disruptive innovation? Explain.
