Influence the Design for DFT

The Pioneering of DFT

Testability, as a concept, was created in 1964 based on a concept formulated by Ralph A. De Paul Jr. during the prior decade, then formally authored by William Keiner, certified by the U.S Congress, and published as MIL-STD-2165. This was before acronyms such as Designing-for-Testability (DFT), Design-for-Test (DfT), or Design-to-Test (DTT) were established to describe specific segmented activities within the fully intended scope of designing for testability. The objective was to influence the design so that it could be used for testing, any and all testing and, concurrently, to influence the design for effective sustainment, or as DSI terms it, Design-for-Sustainment (DFS).

Design For Test-Design For Testability (DFT)

Designing for test, testability, sustainment, etc. must be a multiple disciplinary-inclusive process without design domain barriers. The activity must coexist as an efficient and exhaustive approach that always has an eye on the sustainment objectives and thereby contributes to the forming of a byproduct knowledge-base.

ISDD – Realizing Interdisciplinary Value

As systems continue to increase in both size and complexity, the ability to drill down and find the failure root causes continues to be a growing challenge. Many of the traditional methods to compute low-level reliability or maintainability statistics in complex designs and bring this data to the system level to address system requirements conformance is becoming increasingly costly and challenging.
