All of the effort that went into collecting the information was for nought, because the outcome was always the same. That was collection with a flowchart, but without two or more distinct outcomes.
A second example would be search engine logs. Nobody wanted to make decisions on them, but "we could always trawl them for data later." A decade on, this had never occurred. That was collection with no flow chart. Offloading the logs, parsing them out, making the data available, week after week, month after month, year after year. Wasted effort.
So part of it is "don't waste effort," but the other part is, if there is decent information to collect, you should be doing something with it.
