Ok, but why is it easier? Who is it easier for? The devs deciding how to estimate their work? The scrum guy rolling up completed tickets?
Having been from team to team where estimates were a measure of effort, to a measure of time spent in days to measure of necessity, I don't quite grok why this system is easier or better than using sequential numbers any more than I grok what "estimates" should even mean-it varies as much between teams as the term "devops engineer" does.
So why Fibonacci? Is it just "because Fibonacci"? Wouldn't it be better to identify why some types of decision trees take longer to climb than other on your team and orient your work estimation along those lines?
Consider same for a linear estimate. 2 will say 4 days, 1 will say 5 days, 2 will say 6 day, and 1 will say 8 days. How do you come to a conclusion now, it surely needs more debate, to determine if it is 4 or 5 or 6 or 7 or 8.
If you do not like Fibonacci you can use powers of 2. Like 1, 2, 4, 8, 16, or you can form your own sequence with numbers sufficiently apart. Since Fibonacci standardized it we just use it. -Alexander Jayaraj
