Assess/Optimize Diagnostic Capability of New and Legacy Systems

Calculation of Standard Testability Metrics

Since DSI is the original pioneer of the need for Testability as an integral component of the design development process for the US Department of Defense, and has mentored William Keiner, author of the first Testability Standard (MIL-STD 2165) prior to its acceptance in 1981, we have continued to lead industry in this purpose.

Advanced Testability and Diagnostic Metrics

As the eXpress models are integrated into the system, the design must be able to detect the failures within the context of an integrated diagnostic model, which is a woeful inadequacy of most every other testability analysis. As the models are integrated more “test” constraints become apparent due to the integrated system posing new testing accessibility restrictions. This alone, may significantly degrade the usability of test points that were previously accessible when the design is independent from the other integrated designs.

Simulation-based Assessments

As an integrated component of Integrated System Diagnostic Design (ISDD), we can reuse our existing Integrated Systems’ (fielded product) eXpress models in the companion Operational Support Simulation tool, “STAGE”.
