Book excerpt: A broad consensus exists that weapon system problems are serious, but efforts at reform have had limited impact. Last year, it was reported that DoD's portfolio of weapon programs experienced cost growth of $295 billion from first estimates, were delayed by an average of 21 months, and delivered fewer quantities and capabilities to the war-fighter than originally planned. This testimony describes the systemic problems that contribute to the cost, schedule, and performance problems in weapon system programs, recent actions that DoD has taken to address these problems, proposed reform legislation that has recently been introduced, and additional steps needed to improve future performance of acquisition programs.
