The A Posteriori Difference
A Posteriori leadership remains in the government and/or active in the procurement profession locally and nationally. This allows our work on procurement policies to be informed by not just the theory of procurement or the statute but the real-life challenges for implementation, and compliance management. Our final products are operational in the real day-to-day practices of the profession, in addition to compliant with all laws and regulations.

We excel at understanding government requirements and how to successfully navigate them.

For Other Stakeholders
Procurement expertise is often niche and travels with long-time employees who retire or change roles.
