Requirements definition helps define the product in terms of functionality, features, and cost. It also helps to match the customer's needs with the expected customer benefits. This phase is an important part of our process and insures that we deliver a product that our customer wants.
Some of the critical product parameters defined during this phase include:
Physical characteristics and appearance
Application and user interface features
Cost and packaging
Regulatory / environmental approvals
Once the critical parameters are defined, we can perform a feasibility study to see how the concept can work in practice and be transformed into a specific product prototype. The feasibility study helps to evaluate the product concept, identify problems/concerns, and reduce risks.
