VxWorks LSJ Redacted_Page_3.jpg

This appears to be a section of a Justification and Approval (J&A) document explaining why VxWorks software from Wind River Systems must be procured on a sole-source basis. The document outlines why alternative solutions were not feasible, citing that configuring other software would require unacceptable costs and resources for re-engineering. It emphasizes that the original equipment manufacturer VX Software is imperative for compatibility with existing systems and workbench tools.

The document provides a detailed cost breakdown of potential duplication costs if an alternative solution were pursued, though the specific dollar amounts are redacted. Key cost categories include proposal costs, rework system requirements, hardware changes, system architecture redesign, software architecture redesign, development, and testing/qualification. The document notes that technical data packages for full and open competition are not available due to VxWorks being proprietary to Wind River Systems. The file concludes with a partially completed section about publicizing contract actions under FAR Part 13, referencing FAR 5.101 and 5.203 requirements. The document is dated February 2017.
