Abstract

This thesis explores the use of the Stage-Gate model and its evolution to keep up with its competitors. Stage-gate has its origins in phased project planning developed by NASA. In the 1980s Dr. Robert G. Cooper believed that there was a need for a more dynamic process for new product development and thus the Stage-Gate model was born. Feedback gathered from adopters has allowed the model to evolved by adapting to criticism of older versions. The model has also evolved by observing best practices of top performers and adopting those practices into new generations. The second part covers the adoption of Stage-Gate practices in medical and the military industry. These industries are heavily regulated to ensure safety and security respectively. From the look into these fields, it becomes apparent that the product development in both fields has adopted the use of modern Stage-Gate practices such as feedback loops and iterative design. This literature review concludes by discussing how the Stage-Gate process is evolving in the military and medical industries at different rates due to the fields differences. Ending with talking on the future of Stage-Gate and the possibility of incorporating artificial intelligence into the workflow.
