As a nontrivial bonus, the structure and discipline impressed on the systems-development process can greatly reduce the defects upon delivery rate. Setting standards and using a common approach improves a company's ability to measure performance and status in a meaningful way. A methodology engages both business management and IT management. All these benefits result in better-quality systems developed in a standard manner, which ultimately results in lower maintenance costs. Implementing a methodology provides many benefits.
Companies can reduce the cycle time for the delivery of systems.
Standard processes, tools, and techniques accelerate the process because the learning curve is reduced for both experienced personnel and entry-level new hires. Methodologies can also slash costs. Consistent methods help IT departments spread scarce resources that can be shared across projects. This can even result in the reduction of the number of people that need to be hired. Methodologies reduce failures, rework, and confusion over what to do next.
