The reason they survive is that each one feels too small to bother fixing. Five minutes here, ten there. But run the math across a team across a month and it is days of work spent on tasks that add nothing.
You do not need to automate all hundred at once. You need to find the ten that repeat the most and start there. Frequency is what turns a tiny task into a real cost, so frequency is where you get the biggest return.
We think of these as the jobs a team should never touch. Map them, automate the worst offenders, and put the time back into work that actually moves the business. The list is long, but the wins are simple and they stack up fast.
