Once you've been around in this software business for long enough you see the same articles written over and over again... there will always be articles about estimating software, yet there is no solution to this problem.

Anyhow, it doesn't matter. Software devs are the lowest cog, they don't get to extend the delivery date. All the layers above - management, marketing, sales etc need a date to work to to deliver their work, and they generate the $$$. No-one cares if the software is low quality, as long as it is delivered. Dev team can do further updates to bug fix after delivery. The end.

It is what we seem to call the 'unknown unknown'. Basically something popped up that was not planned for and now you need to research/fix/qa and shove that in. Even our 'known' bits are always underestimated. Because many people are hopeful and willing to 'try harder'.

Heck I personally just did this. I scoped out a story. Then realized I had underestimated it because there was at least 2 tech stacks in the thing I had not used much. So I had to basically drop what I was going to do and figure out some PoC on that. THEN I could write my code.
