So when Scrum teams come up with a story point estimate (usually via planning poker ), they use FIbonacci numbers for those estimates. The use of the Fibonacci sequence in Agile development, particularly in the context of creating user stories and estimating their complexity, is a common practice. For example, project managers can easily estimate the user story in 1h, 2h, 4h, 1day, 2day, 4days, 8days, and many more.
