A project to integrate hardware and software is in execution. The hardware requirements are well-defined with a detailed WBS. The software requirements, however, are vague and frequently change, forcing the team to develop the product incrementally with short feedback loops. The team is very frustrated by the frequency of changes and the chaos that it creates. How should the project manager respond?
a. Ignore the team's frustration and focus on the project goals
b. Eliminate the short feedback loops to allow more flexibility
c. Absorb the team's frustrations and demonstrate positivity
d. Institute a strict change control process for software development
