Enterprise information system modeling for continuous improvement

A three-phase information system analysis and design methodology is being used to continuously improve enterprise information systems as part of a six-step annual business improvement process. Following senior management's strategic decisions on next year's product and/or service portfolio content, interacting financial, management, engineering, and quality improvement processes are analyzed to determine their output product and/or service quality and timeliness. Concurrently, facilities, equipment, and personnel resources required for individual processes are inspected for possible immediate or future improvement. Throughout these analyses minimum essential information (MEI) requirements are derived using the Object Transformation Process Model (OTPM). Individual OTPM models are linked to help identify all pertinent data sources, information destinations, and timing requirements. The linked OTPM models are mapped onto an Embedded Computer System (ECS) model that defines a physical architecture for improving telecommunication paths between all humans, machines and embedded computers that are component parts of the integrated processes. This approach yields comprehensive information system logical and physical architectural models that can recursively guide high-leverage enterprise-wide improvement projects over succeeding fiscal years.
