a processor of a computer system generating a computer readable Rrequirements Traceability and Verification Matrix (RTVM);
said processor storing the RTVM in a computer readable storage device;
providing the RTVM as input to each of the BRR, SRR, and PDR, said RTVM depicting hierarchical relationships between the business requirements and the system requirements, said RTVM further depicting hierarchical relationships between the system requirements and the component requirements;
updating the RTVM with verification information relating to the business requirements, after the BRR exit criteria have been determined to be satisfied and before the step of developing system requirements has been initiated;
updating the RTVM with verification information relating to the system requirements, after the SRR exit criteria have been determined to be satisfied and before the step of developing component requirements has been initiated;
updating the RTVM with verification information relating to the component requirements, after the PDR exit criteria have been determined to be satisfied and before the steps of developing component designs and developing test plans have been initiated; and
updating the RTVM with verification information relating to the component designs and test plans, after the CDR exit criteria have been determined to be satisfied.

Abstract
A method for implementing a project for a customer. Business requirements are developed for the project and are reviewed for acceptability in accordance with Business Requirements Review (BRR) exit criteria. System requirements are developed for the project and are reviewed for acceptability in accordance with system requirements review (SRR) exit criteria. Component requirements are developed for the project and are reviewed for acceptability in accordance with Preliminary Design Review (PDR) exit criteria. The business requirements are decomposed into the system requirements. The system requirements are decomposed into the component requirements. A Requirements Traceability and Verification Matrix (RTVM) is generated when the business requirements are established. The RTVM is updated throughout the life of the project. The RTVM includes verification information relating to the business requirements, the system requirements, and the component requirements. The RTVM depicts hierarchical relationships between the business requirements, the system requirements, and the component requirements.
