Diligent Consulting

What Diligent Consulting does

Diligent Consulting Inc. is a privately held, Service Disabled Veteran Owned Small Business (SDVOSB) founded in 2001 in San Antonio, Texas by David Cerminaro (a disabled veteran and retired Air Force officer) and Doug Klaymeier. The firm provides federal IT services — primarily software development, legacy application modernization, cybersecurity, and ERP/logistics systems support — to the U.S. Department of Defense, with a heavy concentration in U.S. Air Force commands, supplemented by work for DISA, DLA, DOT, and AFMRA. Its delivery framework centers on the proprietary Evolution Solution SM methodology, a three-tier (Level I assessment, Level II revitalization, Level III cloud transformation) approach that integrates EvolveWare's Intellisys Platform for automated legacy code metadata extraction and reportedly reduces modernization time and cost by 40-60% while automating up to 90% of system analysis. Diligent also sustains and modernizes mission-critical custom applications such as eBOSS (Air Force Personnel Center), CDSAR, FAPNet, ACPS, KDSS/CMS, TMT, FROID, and cryptologic software (KG-3X family, VACM), and supports MROi/MROi+ depot maintenance ERP work on Oracle eBS/cMRO.

Diligent's business model is a B2G professional services model. Revenue is generated via multi-year task orders under four primary prime contract vehicles — GSA MAS (GS-35F-0475R), OASIS SB Pool 3 SB (47QRAD20D3159), DISA ENCORE III (HC1028-18-D-0039 via Team CSI JV with Indigenous Technologies), and NETCENTS-2 (FA8771-12-D-1003, ordering period ended) — supplemented by subcontractor positions on larger IDIQ vehicles held by Accenture Federal Services, Obsidian Global, Invictus JV/Oasys International, Integrated Computer Solutions, and Command Cyber. Pricing is contract-based: GSA MAS via published price list across SIN codes for HACS, IT Professional Services, Cloud Computing, and Order-Level Materials; DISA ENCORE III via 116 fixed-price labor categories; managed services priced annually based on client employee-base and infrastructure. The company holds CMMI-DEV Maturity Level 3 (continuously since 2006, reappraised July 2022) and ISO 9001:2015 certifications at its San Antonio headquarters, which is required for many federal set-aside procurements. Operations span a San Antonio, TX headquarters, a Dayton, OH Logistics Directorate, and operational support at the Pentagon and Raven Rock Mountain Complex under DISA IIMS-ITSS, with global performance reach via DISA ENCORE III.
