Fibonacci Sequence
The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1. It's often used in Agile estimation for its ability to represent the increasing complexity and effort of tasks. Tasks are estimated using values from the sequence, with each number indicating a relative size or effort, reflecting the natural growth observed in many processes.
Cards sequence: 0, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.
How to Use Fibonacci Sequence in Agile Planning
To use the Fibonacci sequence in Agile planning, begin by presenting the team with a task to estimate. Each team member privately selects a card from the Fibonacci sequence that they feel best represents the effort required for the task. After all team members have chosen their cards, the cards are revealed simultaneously. Any discrepancies in estimations are discussed openly, aiming for consensus. Repeat the process until estimates converge, ensuring accurate planning and task prioritization.
Examples of Tasks Estimated with Fibonacci Sequence
Examples of tasks suitable for estimation using the Fibonacci sequence include software development tasks like implementing user stories, testing new features, or fixing bugs. Design projects such as creating wireframes or conducting usability testing can also benefit from using Fibonacci numbers to gauge effort and complexity.
