Part 1: What is Coincidence Analysis? · Module 1
The mystery of the 100 facilities
Why Does CNA Exist?
You supervise 100 health facilities. A handful keep missing children, quarter after quarter, no matter what you try. The question that keeps you up at night is simple: why does coverage stay low in these places?
Most of us answer that question by rounding up the usual suspect. "It's the training." Or "it's the fridge." We pick one lever, pull it, and wait for coverage to climb. Then it doesn't, and we're baffled, because on paper that facility had the training. The trouble is that low coverage rarely has one cause sitting alone in a room. It usually shows up when a few things go wrong at the same time , and a facility can survive one weak spot but not a particular combination of them.
