Logging work is beyond important. In my company, we also write a lot of scripts so it’s very helpful to keep documentation on how to use each script. We also have to keep track of certain things we tested and how we tested them. We have to keep a detailed record in case someone new joins the project/team they would be able to pick it up quickly. One time I was instructed to perform tests on a certain design study. I kept a record of all the tests I ran and what the purpose of each test was (basically what was going on in my mind when I ran the test). I was later on asked to provide a powerpoint brief explaining the whole process and the logic behind it. Without the logging I did for the 10 or 15 tests performed, I would’ve been completely lost when working on the powerpoint. I would’ve also not been able to communicate my findings clearly and retracing my steps would’ve been almost impossible.
