I just had a similar experience moving into my new flat this year (including the builder forgetting to drill the hole for the power plug). With absolutely no disrespect to the author, because I also learned this the hard way, I'll say that a little bit of BDUF would maybe have saved some time. It was my third iteration or so (sprint?) before I decided to just walk through the entire job step by step and see what other tools I would need and what else might go wrong. I can't just pop down to Lowe's or Home Depot in Singapore, after all.
This especially hits home because my current feature ticket ("Oh, yeah, it looks easy, a couple of days") was under-specified, and what specification there was had flaws. Two weeks later....
For this you have to know upfront that it will be a "big job"... In my case, after the second trip to the hardware store, I still thought that it's just a bad luck, instead of a "serious job". Ended up going several more times of course.
