TEAMS (Testability Engineering and Maintenance Software)

TEAMS provides a method to model the structure and failure behavior of a product at any level (system, unit, module, and component). The TEAMS model analysis outputs include: Testability Figures of Merit (TFOM), fault detection/isolation metrics, undetected fault reports, fault isolation ambiguity reports, detailed test strategy trees, mission reliability calculations, and Failure Mode Effects and Criticality (FMECA) reports.

The ability to model and predict the "failure behavior" and resultant effect on the system is first and foremost in the development of fail-safe, fault tolerant, and effective diagnostic/prognostic capability. The engineer must be able to see how the system will fail and then determine how to address the failure.

Qualtech has developed a complete solution for Integrated Diagnostics (ID) that addresses all the facets of Design for Safety, Testability (DFT), Reliability Analysis, Failure Modes, Effects and Criticality Analysis (FMECA), and maintenance. Design for Safety, Reliability, Testability and minimizing the life-cycle cost of a complex system requires a well-coordinated effort involving people of different expertise. In effect, the model is the means by which people document and convey their understanding of the system, as it relates to their fields of expertise. Qualtech has develop a modeling methodology that is simple and intuitive enough so that people of various disciplines can understand and relate to it, yet powerful enough to be used during the entire life-cycle of a system.
