and suppliers so that quality solutions are delivered more quickly at a lower cost with the most appropriate
technology. Often, teams must coordinate the functions, manage the risks, and handle
information flow as part of a complex relationship with other organizations. CMMI-ACQ provides
guidance for this type of challenge.
CMMI for Services (CMMI-SVC). The CMMI-SVC model was the first real extension to the
CMMI Framework. A model addressing service establishment and delivery was created because
the demand for process improvement in services continues to grow (services constitute more than
80 percent of the U.S. and global economy) and stakeholders approached the SEI requesting a
model for services. The model covers the activities required to establish, deliver, and manage services.
It incorporates work by several service organizations and draws on concepts and practices
from other service-focused standards and models, including Information Technology Infrastructure
Library (ITIL); ISO/IEC 20000: Information Technology—Service Management; Control
Objectives for Information and related Technology (CobiT); and Information Technology Services
Capability Maturity Model (ITSCMM).
The Consequence: CMMI Models Are Used Effectively Worldwide
CMMI models are being used by small and large organizations alike in a variety of industries, including
electronics, health services, finance, government, insurance, and transportation [CMMI
Institute 2013]. Adopting organizations include Boeing, General Motors, JP Morgan, Bosch, and
many others in North America, Europe, Asia, Australia, and South America. Adoption statistics
show the worldwide impact:
More than 400 organizations are authorized to deliver training and appraisals.
More than 150,000 professionals have completed the Introduction to CMMI course.
CMMI appraisals have been reported from 74 countries, and an estimated 2.4 million people
work in organizations that have had at least one appraisal since April 2002.
Integration has provided organizations with a number of advantages, including linkage of management
and engineering activities to business objectives; the visibility of the product life cycle
and engineering activities to ensure that the product or service meets customer expectations; leveraging
from additional areas of best practice (measurement, risk management, and supplier management);
robust high-maturity practices; the visibility of additional organizational functions critical
to their products and services; and coupling with relevant ISO standards [CMMI 2004]. In
addition, organizations can more easily pursue enterprise-wide process improvement because each
CMMI model in the product suite is designed to be used in concert with other CMMI models.
The SEI Contribution
The success of the CMMI project resulted from the contribution of a number of teams from industry,
government, and the SEI that worked together to evolve the legacy CMM frameworks into the
CMMI framework. The SEI provided the leadership and architectural vision and acted as the
steward organization, providing a source of sustainment and continuing support for the adoption,
improvement, and evolution of the CMMI product suite. The SEI also worked to ensure the qual-
