Having worked previously as a software project manager, you were pleased to be appointed as the project manager for a new systems integration project designed to replace the existing air traffic control system in your country.

Using such a matrix helps to ensure that each requirement—

a. Adds quality and supports the organization’s quality policy

b. Adds business value as it links to business and project objectives

c. Sets forth the level of service, performance, safety, security, and compliance

d. Shows the impact to other organizational areas and to entities outside of the performing organization
