Problem
Senior associates were using ChatGPT on personal accounts to draft client memos and run document review. Leadership wanted them to keep the productivity but lose the data-exposure risk.
Delivered
Four-week cohort. Week 1: prompt engineering on the firm's enterprise-tier tool. Week 2: data classification + redaction patterns + privileged-data handling. Week 3: Word + Outlook + Excel automation patterns. Week 4: each associate shipped a prompt library covering five of their highest-frequency tasks.
Outcome
Capstone deliverables: 25 prompt libraries, each averaging 38 templates. Average self-reported time saved per associate per week: 4-6 hours. Zero incidents in the post-cohort 30-day window.
