Capability Maturity Model Integration (CMMI) helps firms to integrate process improvement, supporting a productive, effective culture that reduces the vulnerabilities in software, product, and service development. Let’s learn more about CMMI in software engineering as a process improvement tool.
What is CMMI in Software Engineering?
CMMI is a process and behavioural model that assists firms in streamlining the process improvement and supporting productive, efficient behaviours that reduce vulnerabilities in software, service, and product development.
The Software Engineering Institute at Carnegie Mellon University developed CMMI as a process improvement tool for projects, divisions, or entities. The DoD and US government contributed to its development, which is a common need for software development projects. CMMI is currently managed by the CMMI Institute, which was bought by ISACA in 2016.
CMMI Model
The CMMI is developed to improve performance by continuously offering businesses everything required to create improved products and services. However, the CMMI is not just a process model but a behavioral one. Organisations can utilise CMMI to monitor the logistics of improving performance by creating measurable benchmarks. However, CMMI can also contribute to developing a structure for nurturing productive, effective behaviour across the organisation.
Evolution of CMMI in Software Engineering
CMMI was created to merge several business maturity models into a single approach. It was invented from the software CMM model between 1987 and 1997. CMMI version 1.1 was launched in 2002, followed by version 1.2 in 2006 and version 1.3 in 2010. Then the V1.3 version was replaced by V2.0 in 2018.
The model was altered to software engineering in its initial design as a software CMM. As the CMMI versions became more abstract and generalised, it was applied to software, hardware, and service development across different industries. The launch of V2.0 streamlined the process. The CMMI previously covered three main interest areas, including product and service development, product and service acquisition, and service establishment. However, later, these have been combined into a single mode.
Every CMMI iteration seeks to be convenient for businesses to comprehend and use than the past version. Each model is developed to be less expensive and easier to implement or deploy. This promotes businesses to emphasise quality over quantity by creating benchmarks for vetting vendors and providers. This also influences the firms to identify and resolve the problems in the process and reduce the risk. It aims to establish a culture that supports the CMMI model.
CMMI Maturiy Levels
The CMMI model divides organisational maturity into five divisions. The organisations that embrace the model aim to increase the organisation level up to 5. After reaching this level, they are not over the CMMI. Instead, they emphasise maintenance and frequent upgrades.
The five levels are:
Maturity Level 0
In this level, the work may remain incomplete. The business may fail to set the goals and processes or fail to address the organisational needs.
Maturity Level 1
The processes are seen as uncertain and reactive. In this level, the work is completed but delayed and faces a budget overrun. This is the extreme level where the business can see itself in an uncertain environment which increases risks and inefficiencies.
Maturity Level 2
In this level, the project management is achieved. The projects are planned, conducted, and evaluated at this level. However, several issues remain prevalent at this level.
Maturity Level 3
This level allows the organisations to remain proactive instead of reactive. There is a set of standards that guides throughout the projects, programs, and portfolios. The businesses acknowledge their shortcomings and try to overcome them.
Maturity Level 4
In this level, the projects are measured and controlled. The firm is using quantitative data to determine predictable processes that comply with the needs of the stakeholders. The business can manage the risks with data-driven insights into the process vulnerabilities.
Maturity Level 5
The processes are steady and flexible in the organisation. In this stage, the organisation can be in a constant state of enhancing and reacting to the evolutions and other opportunities. The organisation is stable, which enables it to become more agile and innovative in a certain environment.
After reaching levels 4 and 5, the organisations can enter into the high maturity level where they are continuously changing, adapting, and growing to address the needs of stakeholders and consumers. Thus, the objective of CMMI is to develop reliable environments, where the products, services, and units are proactive, productive, and efficient.
CMMI Capability Levels
CMMI has some capability levels utilised to praise the performance of the organisation and process enhancement, as it includes an individual practice area highlighted in the CMMI model. It can streamline the process and performance improvemen,t and every level depends on the previous.
Here are the capability levels:
Capability Level 0
In this stage, the performance remains inconsistent
Capability Level 1
In this stage, the organisations begin to address performance problems in a particular practice area. However, there is no comprehensive set of practices.
Capability Level 2
Progress can be found in this level and there is a comprehensive set of practices that address improvement areas.
Capability Level 3
There is an emphasis on accomplishing project and organisational performance objectives and there is a comprehensive set of standards to deal with the projects.
CMMI in Software Engineering- Certifications
CMMI certifications are given directly through the CMMI institute that certifies people, instructors, practitioners, and appraisers. The CMMI institute offers these programs:
CMMI Associate
CMMI Associate Certification shows your dedication and capabilities to performance improvement. The certification certifies that you have the required skills and expertise to implement the CMMI model in the business.
CMMI Professional
CMMI professional is another certification level which shows your ability to use the CMMI model within an organisational structure through strategies for performance, team mentoring, organisational change management, and nurturing an environment of improvement.
Certified CMMI Lead Appraiser
Being a certified appraise, you will be eligible to appraise the entities to determine their capability and maturity level.
Certified CMMI Instructor
The certificate holders of CMMI Instructor receive the benefit the lead instructional courses on CMMI. You only need a subsidising firm that is licensed to use the CMMI model.
Concluding Thoughts
In a nutshell, it can be said that CMMI in software engineering is an effective model to improve processes while supporting an efficient culture that prevents risks in product, software, and service development. Hence, the gain the skills and knowledge on how to apply this model, you should enrol yourself in these certifications.
