QMS and CMMI in software company

Answer:

QMS or ISO 9001 has the same requirements for every industry and it is applicable to any industry as well. QMS for software companies deffer from QMS in other industries only in sense that software companies has different processes than other industries and those processes must be aligned with ISO 9001.

Capability Maturity Model Integration (CMMI) is a process improvement training and appraisal program and service administered and marketed by Carnegie Mellon University (CMU) and required by many DoD and U.S. Government contracts, especially in software development. CMU claims CMMI can be used to guide process improvement across a project, division, or an entire organization. CMMI defines the following maturity levels for processes: Initial, Managed and Defined. Currently supported is CMMI Version 1.3. CMMI is registered in the U.S. Patent and Trademark Office by CMU.

CMMI currently addresses three areas of interest:
- Product and service development — CMMI for Development (CMMI-DEV),
- Service establishment, management, — CMMI for Services (CMMI-SVC), and
- Product and service acquisition — CMMI for Acquisition (CMMI-ACQ).

CMMI was developed by a group of experts from industry, government, and the Software Engineering Institute (SEI) at CMU. CMMI models provide guidance for developing or improving processes that meet the business goals of an organization. A CMMI model may also be used as a framework for appraising the process maturity of the organization.
