Numerous repeated studies have confirmed that less than 25% of software development projects ever meet their objectives and goals. Extensive research has shown that these time and cost overruns can be easily avoided, because the processes that produce high quality software on time, and on budget, are well-known.

Designed to minimize the high frequency of failures in outsourced software development projects, the CMMI model has been introduced around the world to assess a vendor's ability to complete developmental projects within a specified budget and timeframe. CMMI is a process improvement approach that provides organizations with the essential elements of effective processes that ultimately improve their performance.

Capability Maturity Model (CMM) is a means of ranking organisations' IT processes. This model has been employed by many companies to measure and improve their software and system development processes.

The CMMI process gives an organization all of the latest best practices for software and service development and its continuing maintenance. CMMI models improve best practices of previous models. It does so by enabling the following methodologies:

1. management and engineering activities are linked much more closely to their business objectives.
2. scope and visibility of product life cycle are expanded to make sure that the software development always meets client expectations through improved activities.
3. measurement, risk management, and supplier management incorporate lessons from additional areas of best practice.
4. more robust high-maturity practices are implemented.
5. additional organizational functions are addressed which are critical to an organization's products and services.
6. compliance with relevant ISO standards which embodies closer control.
