I agree with most of things on this article with and additional caveat: estimates are also a function of who is going to do the work. If I have a team of 5 offshore devs who need hand holding, 2 seniors who are very skilled, and two mid level or juniors, how long something will take, what directions will be given, and even the best approach to choose can vary wildly depending on which subset of the team is going to be working on it. On top of all the other problems with estimates. This variance has degrees, but particularly when there are high-skilled on shore engineers and low skilled offshore ones, it leads to problems, and companies will begin to make it worse as they get more cost sensitive without understanding that the different groups of engineers aren't perfectly fungible.
And how many other parallel work streams are going. So many times I’ve estimated something to be “5” and it’s gone into my queue. Then people are wondering why it’s not done after “5” estimation units have passed and I’ve got “10” points worth of more high priority tasks and fires at every moment of my career
Excellent example why anything else than work hours is pointless to estimate in.
