Twice is a (reasonable) minimum.
- smt88 8y agoI've found that under-promising and over-delivering requires me to quadruple my best estimate. Unfortunately, lots of us bid against people who over-promise. By the time the project is obviously behind schedule, it's too late, and the client can't switch to someone else.
- Deganta 8y agoI see the 90% rule as a recursive function: First we get 90% of the whole work in the first iteration, then 90% of the remaining code (now we are 99% complete), then 99.9% and so on. The iteration is stopped when the software has enough features and an acceptable level of bugs to be considered complete. What complete is depends entirely on the field of the software. For a proof of concept software we can stop after the first iteration, but for a safety critical software we might need 3, 4, or even more itarions.
- squirrelicus 8y agoI like this, it rings true in my experience.
- maxxxxx 8y agoTo be honest from my experience usually it’s a factor of five to get to full completion.
