Defining requirements is the first step in product development. Requirements should originate from the customer, be allocated throughout the design and provide the basis for test verification. We have expertise in refining customer needs into achievable, verifiable and unambiguous requirements for government, military and commercial products. We have performed requirements analysis as part of our own product development and have also provided it as a service to customers' efforts. In each case, our aim is to ensure that requirements are identified, tracked and verified as early as possible in the development cycle to minimize the potential for rework.
