Case Studies

Each of these started as one kind of problem: work that broke down between two teams, in a different industry each time. The method was the same every time. Follow single pieces of work from start to finish, check that the reported gap is even real, and fix the handoffs before automating anything.

The numbers come from each client's own before-and-after reporting, not a formal study. That difference matters, so it is noted here rather than hidden.

Standardizing Operations Across Multiple Clinic Locations

A pain management practice expanding to several locations had each site running a locally evolved version of the same process, with costs rising and patient experience diverging. Standardizing the handoffs between scheduling, intake, and billing while leaving genuinely local decisions local achieved a 25% cost reduction without a drop in experience scores.

Rebuilding a Staffing Pipeline Around Retention Rather Than Speed

A medical staffing company measured recruiters on time-to-place, which quietly selected for candidates who accepted quickly rather than those who stayed. Reweighting the process around twelve-month retention, with screening automation handling the mechanical filtering, produced 90% retention and 50% faster placements at the same time.

When Customer Service and Inventory Are the Same Problem

A medical supply distributor treated slow support and frequent stockouts as two separate failures and proposed two hires. Tracing a month of tickets showed a single root cause: stock state was not observable at the moment a customer asked about it. Response time fell from 24 hours to 2, stockouts from 30% to 5%, operating costs by 30%. Neither hire was made.

Coordinating a Campaign Across Fifteen Countries Without Flattening It

Global WASH campaigns for UNICEF showed unexplained performance variance between regions. The assumption was that weaker regions needed better assets. The actual gap was structural: regional teams were making good adaptation decisions that had no route back into planning. Engagement rose 35% and reach 40% once a return path existed.
