TBF people often try to work under the assumption that the problems businesses solve can be squashed into the same mold too. In my anecdotal experience assuming this and assuming that everyone works the same way is correlated, so much so I assumed without thinking that they have the same cause.
@robryk that's a fair point, I will think about that!
A particular example of same-mold thinking I was thinking of was wanting a metric for "how well a given problem is solved right now" and expecting it to be slowly varying over time, which ignores problems where any partial solutions are worthless or nearly worthless.
Yes.
What makes no sense is to expect a good solution that takes a long time to implement to increase the metric gradually while it's being developed/deployed.
Such assumptions lead people to create metric that measure progress of a solution instead of state of the issue, which causes (a) people to declare success when the "progress" metric reaches some threshold lower than 100% (b) fixation on a particular solution.
