Written By: Subrata Guha

1.0 Objective
DQS has conducted an integrated assessment combining ISO 9001, ISO 20000-1, ISO 27001, CMMI-DEV and CMMI-SVC. This case study explains the approach used and benefits derived from this method. All data used in this document are indicative. Actual data could not be shared to protect the confidentiality of the customer.


Integrating CMMI SVC and ISO 20000-1

The Capability Maturity Model® Integration for Services (CMMI-SVC) is a collection of best practices for service providers.  It provides a five level maturity framework for process improvement. Service provider organizations follow this model as a road map for process improvement.  This model is part of the CMMI product suite developed by the Software Engineering Institute (SEISM). SEI has also provided a standard method for process appraisal known as SCAMPISM– Standard CMMI Appraisal Method for Process Improvement.

ISO/IEC 20000-1 is an international standard for Information Technology Service Management. This standard provides specifications for a Service Management System. IT Service providers may adopt this standard for improving IT service management and obtain certification under the ISO certification scheme.

Given these two options, organizations may be wondering how they can benefit from the positive attributes of both. Director of IT Services at UL DQS, Subrata Guha, has developed a new white paper that outlines the similarities, differences and benefits of these two documents, as well as, how organizations may choose to implement an integrated approach.
