Week 1 Discussion Post- SDLC V model

In this week’s reading, one of the topics that caught my attention is the V-Shaped model of Software Development Lifecycle. This model is referred to  as verification and validation model. This model emphasizes and leverages the relationship between the development phases and the testing levels. In this model the most granular unit testing occurs right after the programs have been written. Following this model testing, happens to validate the detailed design. System testing relates to the architectural specification of the system.
The V-model lifecycle and phases has many advantages for the IT auditors. It significantly increases the IT auditors influence with formal procedures and guidelines that identify each phase of the business application life cycle  and helps increases the IT auditors involvement. This model eases the reporting aspect of the IT auditor. All of the phases in the model can be reviewed and independently report to the management about the desired objectives. Based on the IT auditors skills sets the auditors can identify selected parts of the system and get more involved in the technical aspects of the system. The auditors can provide evaluation of the methods and techniques utilized throughout the development phrases of the business application lifecycle from beginning to the end.
