New Product Development Process - Deployment (Launch) Stage
The final stage of the New Product Development Process, the Deployment or Launch stage, includes the remaining steps required for full general release of the product. This stage includes ramp up to volume production, marketing and launch plan implementation, distribution and support.

The post launch review should take place at least three to six months following the initial release of the product. In the post launch review, the overall product performance should be accessed as well as the level of customer acceptance/satisfaction with the product. Significant product issues should be covered as well as potential product enhancements. Lastly, there should be a review of the process in general, and any recommendations for corrective actions.
At the completion of the post launch review, formal responsibility for the product is passed from the program core team to the functional departments. A product manager will generally remain responsible for life cycle management responsibilities for the product.
