A comparative study of six stage‐gate approaches to product development

Some companies to aid the product development process have implemented a stage‐gate framework, as a high‐level representation of the activities required. Such a framework allows the development process to be closely monitored and controlled, using stages of work and review gates. Six different companies have been examined to show the variations in representation. Each approach was compared to a generic four‐staged framework. Companies which are organised mainly in cross‐functional teams adhere strongly to the four stages, namely a low‐phased approach. However, companies organised with a strong functional structure tend to have more phases and gates within each stage, i.e. a high‐phased approach. These additional phases tend to be placed late in the product development process rather than at the start where their effect would be greater. A generic representation of the product development process applicable to various organisations and industrial sectors, provides an architecture for carrying out any business process improvement project.
