Not really, it depends on the tool. I wrote a lot of tooling at my last job: ISTR there were about 15 people when I started and a bit over 30 when I left five years later.

For example one tool took about 3 weeks to get to a usable state but it sped up a production task that previously took one person 15 minutes to the same task being done in parallel over 5 units and taking a total of 3 minutes and still only required one person. At our typical sales volumes, it was a no-brainer: my time was paid for by the end of the next month.

In pretty much any small manufacturing/processing shop there are lots of little wins like this.
