DOD Space Acquisitions: Including Users Early and Often in Software Development Could Benefit Programs, Report to Congressional Committees [open pdf - 65KB]
"Senate and House reports accompanying the National Defense Authorization Act for Fiscal Year 2017 contained provisions for GAO [Government Accountability Office] to review challenges in software-intensive DOD space programs. This report addresses, among other things, (1) the extent to which these programs have involved users; and (2) what softwarespecific management challenges, if any, programs faced. To do this work, GAO reviewed four major space defense programs with cost growth or schedule delays caused, in part, by software. GAO reviewed applicable statutes and DOD policies and guidance that identified four characteristics of effective user engagement. GAO reviewed program documentation; and interviewed program officials, contractors, and space systems users. GAO also analyzed program metrics, test and evaluation reports, and external program assessments."
