The papers were savage, Parliament was in an uproar, and the War Office responded by sending nurses and supplies. In March a sanitary commission finally inspected the hospital. It had been built over a blocked sewer, and a dead horse was in the pipe feeding the water supply. They pulled the horse out and flushed the sewers. The death rate fell off a cliff. Then Florence, who was referred to as ,Lady with the Lamp, went home and did the part almost no one remembers. She sat down with William Farr and a team of clerks at the General Register Office and dug the deaths out of records nobody had assembled. Annual mortality in the East ran near 23%. Wounds accounted for 3 points of it. Disease accounted for more than 18. Compare that to a man the same age back in England died at roughly 1% a year. She put the whole argument on one page as a diagram you could read at a glance. In 1858 they elected her the first woman fellow of the Royal Statistical Society. In 1963 a sociologist named William Bruce Cameron wrote the line everyone now credits to Einstein, and he wrote it as a complaint about people who draw charts instead of thinking. Not everything that can be counted counts, and not everything that counts can be counted. He named two problems. Numbers that don't matter, and things that matter but resist counting. He skipped a third, and the third can that cost you money too. Numbers that matter, already sitting in your system, that nobody has connected to each other. The death rate at the military hospital was the third kind. The deaths were recorded. The hospital setup and design was known as well. Few looked at them together. Here's the third kind on you can see tomorrow morning. Water and sewer runs $2,400 over budget. It lands on the variance report as a line item. Somebody types "increased usage" in the comment field and the meeting moves on. Meanwhile the submeter on unit 118 has been reading four times the property average for eleven weeks. Same software. Two logins apart. No report in the building connects them. That $2,400 is a flapper valve. And because nobody found it, it goes into next year's budget as a permanently higher baseline. You just funded the toilet forever. A problem with no answer gets solved. A problem with the wrong answer never does.
