- Involved team: Mainly engineering and manufacturing; however, include Marketing and Finance as needed. Various suppliers and consultants may be involved.
- If the product can reasonably meet the requirements, estimated costs, reproducibility and time frame (i.e. the business case is still acceptable), then use the detailed PRS as the 'input' to the next phase. During the later prototyping stage the product will be compared to this specification to ensure that the product has been correctly design and implemented. This is called Product Verification.
- Product-level, technical creativity takes place in this stage.
- If the business case is not acceptable, then the design requirements must be modified to create an acceptable product or the project can be scrapped (incurring moderate losses). Also, the project can safely be stalled at this point in case, for example, funds are not yet available to proceed to the next phase or some technology or science needs to be developed or validated (usually a separate R&D project). This phase may need to be repeated if funding is re-negotiated.
