Integration maturity metrics: Development of an integration readiness level

In order to optimize the process of complex system integration, it is necessary to first improve the management of the process. This can be accomplished through the use of a generally understood metric. One such metric is Technology Readiness Level (TRL), which is used to determine technology maturity, but does not address integration maturity. Integration Maturity Metric (IMM) requirements are developed through review of aerospace and defense related literature. These requirements are applied to currently existing integration maturity metrics, and the proposed Integration Readiness Level (IRL). IRL is then refined to fully meet these requirements, and applied to three aerospace case studies, along with the other identified metrics, to compare and contrast the results obtained.
