One of the reasons IT systems become complicated is the tendency to use computers to do things that humans should do and to use humans to do the things that computers should do.
You’d think this would be the one thing we as an industry would get right, but the truth is that more often than not the industry gets it precisely wrong. Humans should only do what only humans can do. Computers should only do what only computers should do.
Of course, there is that gray area where there are tasks that both computers and humans can do. What then? I have to give that answer a resounding “it depends” answer… Don’t be afraid to think for yourself.
