Our HR team was drowning in repetitive inquiries, spending over 15 hours per week answering the same questions about benefits, PTO policies, and employee handbook items. Employees often waited for responses, which created frustration and prevented our HR team from focusing on strategic initiatives that could drive real organizational impact. I led the design and implementation of an AI-powered Ask-HR agent using Claude, integrated directly into Slack where employees already communicated. Working closely with our Head of IT & Security, I connected the agent to our knowledge base and established a governance framework to ensure accuracy and appropriateness. The most critical challenge was tuning the system to provide reliable answers while intelligently escalating sensitive questions that weren't suitable for a public Slack channel. I piloted the tool with a small group, continuously refined the prompts based on real interactions, and then rolled it out company-wide with ongoing monitoring and adjustments. Within the first month, the agent handled ~80% of routine questions and saved the HR team 8-10 hours per week. Employees loved the instant answers and appreciated no longer needing to hunt through our Notion employee resource center or policy documents. The agent even became a helpful resource for HR team members handling escalated questions. The impact was visible to our entire executive and leadership teams, who saw measurable improvements in both team efficiency and employee satisfaction scores.
