Extending Information System Integrability Index with CMM Model. A Preliminary Proposal

Development and maintenance of information systems often face integration and re-factoring challenges; therefore diminishing similar difficulties is stressed within this paper. Research was based on literature review of several integrability parameters, describing an information system, where the goal was finding optimal specifications that need to be met to build an integration friendly information system. As a result, a model of parameter groups, which should be included in development, was composed and we named it integrability index. Also a comparison between the index and the Capability Maturity Model was preformed and parallels between them were searched for. Both models are significant to information system improvement and indirectly to business processes they support.
