Integrate Diagnostic Engineering into Overall Product Development Process

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

Integrate Test and Diagnostic Tools via ATML

While the creating of exceptional diagnostic savvy in the eXpress model is unmatched throughout industry, the natural next objective would be to somehow transfer that diagnostic savvy:

  • To an on-board reasoning or Integrated Health Management capability in a vehicle;
  • To critical equipment in an operational environment directly or through an API;
  • In the field on a portable device to step up the Guided Troubleshooting game, or;
  • In a Test Engineering or production application in concert with any capable ATE.

Facilitating All Levels of Design Architecture

The eXpress Diagnostics Model is effective for all levels of the design architecture and can be expanded or enriched to facilitate the Diagnostic Design or the Sustainment objectives at any time.
The approach for initiating towards the goal of achieving diagnostic effectiveness for any design begins with identifying where we are in the design development or design support lifecycles, while also considering the diagnostic or sustainment requirements or objectives. The eXpress model captures and extends diagnostic expertise regardless of where we are in the design or sustainment lifecycles and for any sustainment implementation.

Data Interoperability

In the Design Development paradigm, eXpress has a robust and unique capability that permits it to exchange component attributes, functionality and testing data effectively through its robust and unmatched diagnostic design data capture, organizing and structuring capabilities.

Once captured in eXpress, many lower level designs can be fully brought right into the test environment from the design. Whether this is a capability that is suited for the lab environment to work with common Automatic Test Equipment or later in the field to maximize operational objectives, ISDD leverage data interoperability for test and far beyond!

Diagnostic Preparedness for AIA/ASD- S5000F

Dismissing the Benefit of being Diagnostically Proactive?

In viewing various applicable portions of the detail of the proposed IEEE S500F as it currently exists in the public domain, it is still unclear if any data structure is planned to be significantly robust to support the diagnostic engineering activities involved during the collaborative design development lifecycle for large, multi-organizationally Integrated Systems. To dismiss this proactive approach to designing for sustainment in the design development lifecycle can be an unfortunate lost opportunity to establish a collaborative approach to establishing the diagnostic integrity baseline for any complex system or equipment.

Incorporate Multiple Technologies into a Single System Assessment

Many of the ideas and concepts regarding the targeting of an “agile” maintenance strategy for System or the System of Systems (SoS) begin with the formalizing of a unified approach to collectively capture the functionality of the participating designs into a robust integrated systems’ design development and process. But this design development process must be able to fully assess not solely the top-down functional allocation Systems’ Design and Sustainment Requirements (Operational Availability, etc.) but also be fully positioned to assess and validate the functional and failure cause (root cause) propagation from the bottom-up.
