As an engineer I finally got to take the training course our techs go through and experience how a tech uses the software which we (engineers) developed and maintain. It was eye-opening. One particular example relevant to this discussion is the old version of the equipment had physical potentiometers which the tech would adjust to get a desired meter reading. The new equipment has you just type a number into a textbox in a Windows program. BUT - it doesn't even provide a slider or up/down arrows, you have to play The Price Is Right inputting guessed over/under numbers until a measured output in a second text box matches a desired value. It's clear that when the transition was made from physical controls to software based controls, not enough thought was given to ergonomics and how it would be used by an actual human.
