A Posteriori was founded in 2016 by organizational management professional and Chief Procurement Officer Sean Carroll. The name “A Posteriori” was selected to represent the true role of a management consultant, reflecting the obligation to base decisions and guidance on observations and experience, eliminating assumptions and symptoms, and in favor of a focus on addressing true root causes. The principals of A Posteriori have experience designing and implementing procurement processes at utilities, K-12, higher education, Counties, Towns, Villages, law enforcement, emergency management, and statewide political subdivisions in commodities, services technology, and construction contracting spaces. A Posteriori brings expertise in social equity program management, sustainability, and resiliency efforts, piggybacking, cooperative purchasing, omnibus and specific legislative activity related to procurement, agile and waterfall methodologies, as well as design-bid-build, design-build, and public-private partnership methodologies. This includes regulation and rule-making processes at local and state government levels. In the private sector, the principals have also been involved with national telecom advocacy, small business strategic planning, vendor preparedness to respond to solicitations, and local, regional, and statewide campaigns for issues and individuals. In 2024 alone, A Posteriori LLC and founder Sean Carroll have trained over 1500 individuals, and elected leaders on efficient, effective and ethical public procurement and countless businesses on eliminating barriers to participation and expanding opportunities in the public process. The design and execution of these instructional and educational opportunities are critical to the strategic role of procurement people, processes and platforms.
