i made a minor mistake in a calculation that altered some indicator on 4 records, but they were very big records. they got moved from one classification to another so it was not the end of the world. i fixed the calculation but it took a few hours to resync all the data and the users were grumpy. but i took decisive action to stop work for 2-4 hours and fixed the problem. that’s the action of a leader and i wonder if they’ll recognize it or if they’ll focus on the inevitable mistake. i guess the problem with making every data system look magical is that one mistake can get blown up into a big deal. i don’t expect that to happen, but i plan for the worst. all systems should have buffers, especially "efficient" ones.
