You are project manager on a systems engineering project designed to last six years and to develop the next-generation corvette for use in military operations. You and your team recognize that requirements may change as new technologies, especially in sonar systems, are developed. You are concerned that these new technologies may lead to changes in the scope of your product, which then will affect the scope of your project. Therefore your requirements traceability matrix should include tracing requirements to all the following project elements EXCEPT—

a. Business needs

b. Product design

c. Product development

d. Project verification
