Fibonacci series values are commonly used in Poker Planning because they effectively represent the inherent uncertainty in estimating larger tasks. The sequence (0, 1, 2, 3, 5, 8, 13, …) illustrates how the precision of estimates decreases as Task complexity increases. This scaling factor acknowledges the reality that predicting the effort required for more complex items is inherently more difficult and prone to greater variability.
Using the Fibonacci sequence helps teams manage expectations around the accuracy of their estimates. It serves as a reminder that smaller tasks can be estimated with more precision, while larger tasks carry more significant uncertainty. This approach encourages teams to break down large tasks into smaller, more manageable pieces, facilitating better planning and reducing the risks associated with vague or overly optimistic estimates.
