CMMI in Software Engineering

CMMI in Software Engineering

CMMI in Software Engineering  Originally created for the U.S. Department of Defense to assess the quality and capability of their software contractors, CMMI in Software Engineering models have expanded beyond software engineering to help any organization in any

industry build, improve, and measure their capabilities and improve performance.

For over 25 years, high-performing organizations around the world have achieved demonstrable, sustainable business results with CMMI.

Descriptive Practices Focused on Improvement

CMMI best practices focus on what needs to be done to improve performance and align operations to business goals. Designed to be understandable, accessible, flexible, and integrate with other methodologies such as agile, CMMI models help organizations understand their current level of capability and performance and offer a guide to optimize business results.

What is CMMI

The Capability Maturity Model Integration (CMMI) is a process and behavioral model cmmi in software engineering helps organizations streamline process improvement and encourage productive, efficient behaviors that decrease risks in software, product and service development.

The CMMI was developed by the Software Engineering Institute at Carnegie Mellon University as a process improvement tool for projects, divisions or organizations.

The CMMI starts with an appraisal process that evaluates three specific areas: process and service development, service establishment and management, and product and service acquisition. It’s designed to help improve performance by providing businesses with everything they need to consistently develop better products and services.

Why CMMI in Software Engineering

  • Due to a process model;
  • Behavioural model. Businesses
  • To tackle the logistics of improving performance by developing measurable benchmarks;
  • Create a structure for encouraging productive, efficient behavior throughout the organization.

CMMI Maturity Levels

The CMMI model breaks down organizational maturity into five levels. For businesses that embrace CMMI, the goal is to raise the organization up to Level 5, the “optimizing” maturity level. Once businesses reach this level, they aren’t done with the CMMI. Instead, they focus on maintenance and regular improvements.  

CMMI’s five Maturity Levels are:


Processes are viewed as unpredictable and reactive. At this stage, “work gets completed but it’s often delayed and over budget.” This is the worst stage a business can find itself in — an unpredictable environment that increases risk and inefficiency.


There’s a level of project management achieved. Projects are “planned, performed, measured and controlled” at this level, but there are still a lot of issues to address.


At this stage, organizations are more proactive than reactive. There’s a set of “organization-wide standards” to “provide guidance across projects, programs and portfolios.” Businesses understand their shortcomings, how to address them and what the goal is for improvement.

Quantitatively managed:

This stage is more measured and controlled. The organization is working off quantitative data to determine predictable processes that align with stakeholder needs. The business is ahead of risks, with more data-driven insight into process deficiencies.


Here, an organization’s processes are stable and flexible. At this final stage, an organization will be in constant state of improving and responding to changes or other opportunities. The organization is stable, which allows for more “agility and innovation,” in a predictable environment.

Once organizations hit Levels 4 and 5, they are considered high maturity, where they are “continuously evolving, adapting and growing to meet the needs of stakeholders and customers.” That is the goal of the CMMI: To create reliable environments, where products, services and departments are proactive, efficient and productive.

What benefits CMMI can bring to business:

  • Increased customer satisfaction
  • Improved success with landing and retaining new clients
  • Better productivity and efficiency, which will create more profits
  • Decreased risk

Latest Version:

CMMI V2.0 helps organizations quickly understand their current level of capability and performance in the context of their own business objectives and compared to similar organizations.

Designed to optimize business performance in an ever-changing global landscape, the CMMI V2.0 model is a proven set of global best practices that enables organizations to build and benchmark the key capabilities that address the most common business challenges, including:

  • Ensuring Quality
  • Engineering & Developing Products
  • Delivering & Managing Services
  • Selecting & Managing Suppliers
  • Planning & Managing Work
  • Managing Business Resilience
  • Managing the Workforce
  • Supporting Implementation
  • Sustaining Habit & Persistence
  • Improving Performance

CMMI is applicable to

CMMI has been adopted by government organizations and across many industries (e.g., software, finance, manufacturing, services).

SSAE 18 Assessment:

It is required for the service organizations performing outsourcing services which affect financial statements of their client.

If you are an organization providing below mentioned services, you may be asked to provide a SSAE 18 type 11 audit report signed by CPA registered in US.
