Abstract

Capability maturity model integration (CMMI) is a process improvement methodology employed in software industries for process appraisal. The success of CMMI in software engineering is the inspiration behind this interdisciplinary investigation to find how suitable CMMI is in the manufacturing sector. One of the critical process areas of CMMI, known as 'organisational process focus (OPF)', is selected for the study considering the need for process improvements in the growth of the manufacturing industry. The sub-systems, key performance areas and performance objectives associated with the process area are identified based on which a conceptual model of CMMI is designed. The suitability of CMMI is tested in the industry under study by measuring its effectiveness index using the systems approach. The effectiveness index (EI) indicates how well an organisation realises the benefits of CMMI in terms of output derived at various hierarchical levels.
