      Theory: Engineers are never “done” getting better at time estimation. As soon as you get “better”, you’re asked to estimate bigger, more complex, more ambiguous projects, and you have to level up all over again.

      I have three measure: 1/ done before tomorrow ; 2/ looks like something I already did in less than a week, so something like that ; 3/ not the least idea, do you want that we play dices together to fill your columns?

      for compsci, a professor told us that it was absurd to ask estimates to dev: our work is by essence to automate things. Either the thing is already automated, and you don't need an estimate anymore. Or it's a new thing to automate, and you don't know yet how it can be done :)

      This is an idea I've been trying to promote for years, partly as justification for my inability to estimate well, and partly because I believe it's true. Automation makes the familiar trivially and quickly repeatable, and what work remains to be done is completely unknown.

      Slight dissent from me. Perhaps I'm naive, but I suspect this attitude is only tenable because our industry is relatively young. *Many* apps reimplement the same functionality, in spite of OSS. Meanwhile, we discredit the novelty/ingenuity required in traditional engineering.

      I think my statement took the examples to the extremes by suggesting that tasks that have been done before could be done instantaneously, whereas tasks that are new are completely inestimable. The reality is surely more of a continuum.

      I think most experienced programmers have a reasonable feeling for incidental complexity of tasks and can estimate within some non-shocking tolerance. But accidental complexity is a crap shoot and it overwhelms everything else once your system reaches a certain size.

      Like I go to change the oil which should take ten minutes, but when I take the cap off the windows shatter and the wheels turn into squares. At a certain point something like that happens more often than not. I had a 2-week task turn into 18 months once. :shrug:

          Which is to say, in my experience novelty tends to be less of a factor than hidden complexity.

          I often have the experience that the prep that I find I need to do in order to do something is 10x the cost of the thing, but then it ends up paying off by making 9 other things trivial. And if I know about all 10 things up front, there’s a bulk discount on the prep.

          I strongly believe source code visualization, reporting and exploration tools will make prep much much cheaper especially when you have rich type systems. That & the same but at runtime will guaranteed make software cheaper faster and more fun.
