Combat-Zone Process Engineering & High-Volume Turnarounds: Applying Lean Six Sigma Across Deployed Theaters and Commercial Networks

​In both hostile combat zones and peak commercial supply chains, operational bottlenecks constrain throughput, inflate operating costs, and directly threaten mission success. Whether resolving a 1,900-truck congestion backlog outside a forward operating base or processing millions of packages in a high-volume delivery station, standard management frameworks often collapse under extreme operational stress. Resolving severe distribution crises requires embedding continuous process engineering into high-stress environments, fusing high-velocity commercial logistics with rigid compliance, and building accountable leadership structures that deliver results under pressure.

​Featuring David J. Preston, former U.S. Army Senior Logistics Officer (Colonel / Battalion Commander) and former Senior Operations Manager at Amazon, this closed-door defense session provides a practical framework for operational turnarounds and process optimization. Drawing on his experience deploying Lean Six Sigma in active combat operations in Afghanistan and scaling high-volume commercial logistics at Amazon and DHL Express, David breaks down how defense and industry leaders can eliminate critical supply bottlenecks, merge commercial velocity with military rigor, and lead large teams under extreme conditions.
