The Product Support Business Case Analysis (BCA) Guidebook was signed and released by the Principal Deputy Assistant Secretary of Defense for Logistics and Materiel Readiness (L&MR) in April 2011. The BCA Guidebook is in response to the 2009 Weapon Systems Acquisition Report Product Assessment Team (WSAR-PSA) report recommendation to clarify and codify policies and procedures pertaining to the use of analytical tools, including BCAs, in the life cycle product support decision making process. In addition, the DoD Product Support BCA Guidebook supports Dr. Carter's November 2010 memorandum "Better Buying Power" by providing thorough financial and non-financial analysis to decision makers so that they can make more informed, affordable choices. The BCA Guidebook provides its users a standardized BCA process and is meant to be introductory in nature.
