What is CMMI and in Which Areas is it Applied?

Firms aim to deliver their products and services better, faster, and with a more competitive pricing policy. In the high-technology environment of the twenty-first century, almost all organizations must cope with the production of increasingly complex products and services. Today, the development of all components of a complex product or service by a single organization leads to the implementation of highly intricate business processes. When organizations lack the ability to manage and control this complex development and maintenance process, they can experience significant disruptions.

The problems encountered are related to the organizational structure, which requires an integrated approach. The proper management of assets directly impacts business success. Fundamentally, organizations, especially if they are R&D centers, must adapt the way they manage development activities—a part of achieving their business objectives—to changing conditions in order to sustain their existence.

In this context, various standardization-based bodies worldwide offer maturity models, standards, methodologies, and guidelines that can help organizations improve their business processes. However, most existing improvement approaches focus on a specific part of the business. They fail to provide a systematic approach to the problems faced by most organizations. These models, focusing only on improving one area of the business, have unfortunately continued to sustain the existing flawed processes and barriers within organizations.

What is CMMI?

The development of CMMI began in 1986 at the request of the U.S. Department of Defense, led by the Software Engineering Institute at Carnegie Mellon University. Over time, it has become an industry standard in areas such as business process evaluation and improvement. As of 2016, it is managed by the CMMI Institute, which was acquired by ISACA.

CMMI was created to bring together various business maturity models into a single comprehensive framework. It originated based on the Software CMM model developed between 1987 and 1997 and continued to be updated with CMMI Version 1.1 in 2002, Version 1.2 in 2006, and Version 1.3 in 2010. With the release of CMMI V2.0 in March 2018, its scope and development norms were updated to meet the needs of the modern era.

CMMI is fundamentally a process improvement and structuring model that offers the opportunity to avoid or eliminate flawed processes and the barriers that arise during development and production steps. It is one of the most effective models for addressing development activities applied to products and services. It covers activities throughout the production and lifecycle, from the initial concept through design, production, and delivery, to post-sales support. It focuses on structuring the business processes necessary to build and sustain the total product.

CMMI is a broad process improvement model designed for a comprehensive scope, containing detailed components, process steps, and guidelines, with ongoing academic studies conducted within the institute. Therefore, it is quite difficult to cover the topic in a single article. To form a clearer picture in our minds, we will continue to explore CMMI from a broad perspective in different articles.

What are the CMMI Types and in Which Areas are they Applied?

CMMI types are a set of customized norms designed to cater to organizations operating in different sectors. They enable them to manage and improve their business processes more efficiently and effectively. Each CMMI type offers specific process areas and practices, defining the necessary operational steps for organizations to achieve their goals. These types consist of four main categories, with each category covering different business lines:

• CMMI for Development (CMMI-DEV)
• CMMI for Services (CMMI-SVC)
• CMMI for Acquisition (CMMI-ACQ)
• CMMI for People (CMMI-PC)

CMMI for Development (CMMI-DEV)

CMMI-DEV focuses on improving software, hardware, system, and product development processes. It concentrates on advancing developments through more effective and efficient processes throughout their lifecycle. The model covers all development processes from the design of products and services to their delivery. Requirements gathering, design, production, integration, testing, and maintenance stages are also part of this process improvement practice.

Software development companies, firms conducting R&D projects, product development teams, and organizations operating in engineering fields aim to improve their processes using CMMI-DEV.

CMMI-DEV offers certifications for process improvement in various areas. These certifications include:

Software Development

Covers certifications for improving processes related to the management, design, coding, testing, and maintenance of software projects.

Hardware Development

Includes certifications covering processes from the design of hardware products to their production and integration.

System Development

Contains process-oriented certifications for improving the development, integration, and maintenance of complex systems.

Product Development

Provides certifications for development processes covering the lifecycle of physical products. It aims for improvement in processes from the prototype stage to final product delivery.

CMMI-DEV certifications in these areas help organizations make their development processes more effective and efficient. In the production of card-based and biometric access control and security systems, Ones Technology is the only company to have received CMMI Level 3 certification under both the software and hardware categories of CMMI-DEV for its developments on BioAffix. The most important factor behind this success is its unique process improvement procedures implemented within the scope of models like CMMI. You can get an idea of the process improvement steps applied by Ones Technology by reviewing the blog article titled “CMMI Process Improvement Guide in the BioAffix Example.”

CMMI for Services (CMMI-SVC)

CMMI-SVC centers on objectives such as increasing quality, ensuring manageability, and improving processes in service-based business lines. The primary goal is for service providers to offer higher quality service to customers. Processes such as service planning, management, and delivery are addressed within this model. It focuses on topics like customer relations, management of service agreements, service continuity, and operational success. IT service providers, customer support units, consulting firms, public services, and other service-based organizations benefit from CMMI-SVC to make their service processes more effective.

Similar to CMMI-DEV, CMMI-SVC offers certifications for various business lines within the scope of process improvement. These certifications include:

IT Services

Includes certifications related to information technology service management, IT support processes, and the effective management of IT infrastructure.

Customer Support and Call Centers

Offers certifications for improving customer service, call center management, complaint management, and support processes.

Consulting Services

CMMI for Acquisition (CMMI-ACQ)

CMMI-ACQ concentrates on improvements related to the acquisition processes of products and services. It encompasses a series of improvement processes aimed at making procurement in supply chains more strategic and efficient. It offers a wide range of improvement strategies, from acquisition planning and supplier relations to contract management and quality control processes. By aiming for strategic acquisition decisions and risk minimization, it provides organizations with advantages such as cost-effectiveness, crisis management, budget control, and savings. Public institutions, private companies, and organizations where supplier relations are critical, such as the defense industry, aim to improve their procurement processes using the CMMI-ACQ model.

CMMI-ACQ is a model developed to improve acquisition and procurement processes. It includes certifications for areas covering supply chain management and product and service acquisition processes in various sectors. The certification areas addressed by CMMI-ACQ are:

Product and Service Acquisition

Includes certifications for organizations on planning, managing, and optimizing their product and service procurement processes. Contract management, quality audits, and supplier evaluation are within this scope.

Supply Chain Management

Covers the processes of procuring materials, products, components, and services. It offers certifications for monitoring supplier performance, contract management, and improving logistics processes.
