CMMI, short for Capability Maturity Model Integration, is an elaborate version of CMM with the addition of an integration module. Earlier, it was challenging to integrate the other three modules in a specific discipline, so the experts started using an upgraded version known as CMMI. The fundamental objectives of CMMI are: Meeting all the end-user requirements and expectations Creating value that sounds impressive to the investors of stakeholders Support market growth Enhancing the quality of the products or software system under question Improved market reputation that comes with excellent product development and delivery. CMMI Maturity Levels This model categorizes the maturity level of an organization into five levels. The aim of the team is to raise the business to level five and then focus on the maintenance part. Maturity Level 1: Initial At an initial level, processes are ad hoc and chaotic and usually do not have a stable environment. Organizations do create products and services but often exceed their budget and deadlines. They have a tendency to over-commit and meet expectations by abandoning the process. Maturity Level 2: Managed The organizations with second-level maturity are a bit managed. They create plans and ensure that they stick to their standards even in times of crisis. The management checks the progress and the workflow every now and then, ensuring that all their clients are satisfied with the product or services they get. Maturity Level 3: Defined The next level of maturity that an organization gains is when it covers the aspects of levels two and three. They have detailed process descriptions and procedures that their teams would follow to meet the user requirements. Another difference is that, at maturity level three, the processes get managed proactively with a thorough understanding of the interrelation between the test strategies. Maturity Level 4: Quantitatively Managed After the organization have met the maturity of level 2, 3, and 4, it reaches a quantitatively managed position. They use all the quantitative aspects as a reference to pre-determine the process performance and plan things accordingly. A better idea of the process and its outcomes ensure negligible chances of failure. Maturity Level 5: Optimizing It is the highest level of maturity and the organizations who have achieved it focus on continuously improving the process performance. They use incremental and innovative technical improvements to maintain and upgrade their existing products and services. After the business reaches the highest level of maturity, the only task left is to maintain and entertain the modification requests.
