Re: Whatever happened to measuring output?
Measuring output was never a thing.
Let me tell you about a little experience I had way back in the early 1990s. I had finished my licence in accounting at that point, and was looking to a future of bookkeeping (thank God that didn't work out). My future wife (at the time) had a friend who managed a gym. He was interested in putting his accounting on a computer (yes, in those days it was a question). He asked me if I would agree to go with him to evaluate some accounting products. I agreed readily.
We ended up in a (for the time) savvy business shop, waiting for a demo of a certain accounting product that shall remain nameless lest I get a lawsuit. There were six people there, representing at least three prospective customers. Reminder : these were the days where a 486DX was the height of technology, and Windows was version 3.11.
We got a demo all right. About 15 minutes of showing how to enter invoices and other fascinating accounting stuff (yes, that is satirical). Then we got about 95 minutes of how you could configure the software to record and document how often the users hit the keyboard, how often they made mistakes, how quickly they completed the entry of a record.
In the early 90s. When computers had, at most, 1MB of RAM and 33Mhz of CPU power.
I leave it to the reader to guess just what todays' accounting packages can do - as far as going full Big Brother on the employees is concerned. From that experience I learned that actually doing the accounting is a secondary, if not tertiary, objective as far as accounting software is concerned. The primary objective is clearly detecting who the slackers are.
YMMV, but I'm glad I ended up as a programmer.
