Understanding Modular Open Systems Approach and Why it Matters for DoD

How is the Department of Defense faring with incorporating Modular Open Systems Architecture (MOSA) into its technology development processes? Recent legislation requires acquisition programs to implement a MOSA to the maximum extent practicable. Anne McDonough, Assistant Director at the Government Accountability Office (GAO), joins the podcast to describe what MOSA is, who owns the MOSA approach on a program, and what the benefits and risks are as well as how policy can affect implementation. In this episode, Anne covers a recent GAO report that evaluates the extent to which DoD is able to implement MOSA in its programs.
