Too Long; Didn't Read
Estimating IT projects is a pain. When I started my path and tried to estimate my time spent while being a developer, I always underestimated things. Every time there would appear a job I didn’t account for. Colleagues told me to multiply my estimates by 2, 3, the number Pi. Only it didn’t help to increase the estimation accuracy, just added other problems. For example, when I had to explain where the high numbers came from.
