In a deep dive into the Department of Defense's budgeting process, researchers Jeff Kojac and Olivia Letts unpack the intricacies of the Planning, Programming, Budgeting, and Execution (PPBE) process. Kojac highlights how this decades-old system is heavily influenced by Congress, which complicates decision-making. Letts stresses that understanding PPBE is critical for stakeholders across the defense industrial base, yet few grasp its complexity. Together, they advocate for essential reforms to enhance adaptability in defense budgeting to meet modern challenges.
