Lol, I remember being in a billable environment and making so much shit up. Reading emails? Billed to project Y. Bathroom break? Billed to project X. Politely listening to my boss gab? Billed to project Z.
Now that I manage my own team I let them abuse the Other time entry. I only expect 70-80% billable anyways, which lines up with studies on productivity. Anybody expecting 100% productivity is an idiot and anybody reporting 100% productivity is a liar.
I only care about coarse grained time tracking on my team. I estimate to the quarter day at the smallest, if any task is smaller than that, it shouldn't be a separate WBS item. After all, my end-of-year bean-counter statistics are all based on person days anyways, and I'm not a consultant, so why would I care about tracking to the 15 minute increment?
This would have been amazing for when I lived in a small town in the subarctic. My truck was always useful for things like dump runs or picking up lumber etc. But the town was 20 km end-to-end so I would rarely drive more than 10 km at a time. Of course you'd need a second car or truck for longer trips, but everybody has more than one car in a rural area anyways.
Completely flips the environmental option that many chose where you drive a Prius to work and a truck long haul, to the other way around.
