š AI adoption isnāt a tech problem. Itās a people problem.
Ā
Our team attended the Carahsoft GovExperience Summit yesterday to discuss the practical realities of scaling AI in the public sector.
Here are 4 mission-critical takeaways from the sessions:
1ļøā£ Adoption is the real hurdle. The hardest part of AI isnāt the code; itās culture. Convincing employees that AI is a tool to elevate their workānot replace itāis key.
2ļøā£ Map your bottlenecks. Before deploying new tech, identify your operational friction points. Course-correct early to pave a smooth path for AI integration.
3ļøā£ Reverse-engineer your mission. AI is useless if it delays or disrupts your core outcomes. Start with your mission goals and work backward to find the right tool.
4ļøā£ Robotics & AI are merging. The future of robotics is deeply tied to autonomous decision-making, shifting how we think about readiness and efficiency.
Ā
Special shoutout to the panels on āLeveraging AI to Enhance Efficiency and Readinessā and āThe Business of Government: Aligning Services to Mission Outcomesā for driving these crucial conversations.
