FACE 3.1 Enhancements: What Could Possibly Go Wrong?


The Future Airborne Capability Environment (FACE™) approach is a government-and-industry-developed software standard and business strategy. It satisfies the DoD Modular Open Systems Approach (MOSA) principles with the aim of enabling the reuse of capability-based software components across different hardware computing environments. Adherence to any such standard comes with overhead, especially when there is a new version to grasp.

This 60-minute Webinar introduces the principles of the FACE standard by drawing on the expertise of a FACE Verification Authority, a defense systems OEM, and a Tier 1 provider of a FACE-compliant RTOS. The three presenters examine v3.1 of the standard, the significance of changes to specific user cases, and real-life experiences to help highlight what to expect.

They also discuss the importance of compliance and conformance as defined by the Open Group, as well as the possible degrees of subtle mismatch through the blurring of boundaries between what is defined by a specification and what is implemented in practice. In addition, they explain the significance of the FACE standard to defense suppliers both now and into the future, referencing other, more familiar API standards for comparison including ARINC and POSIX.

The presentation concludes by defining the steps needed to create a conformant software product, highlighting the role that automation can play in making that process as unobtrusive and efficient as possible.

An audience Q&A follows the technical presentation.
