Fibonacci Scale Template

Estimate and assign points for tasks during a work sprint.

The Fibonacci scale is a series of numbers based on the Fibonacci sequence (0, 1, 2, 3, 5, 8, 13, 21, etc.). These numbers are used to estimate and agree upon the amount of effort required to complete a specific task. At the beginning of a sprint, a team will discuss the various tasks that need to be completed and assign points to each task based on the Fibonacci scale. 

About the Fibonacci Scale template

What is the Fibonacci Scale?

The Fibonacci sequence contains exponentially increasing numbers. That’s why agile teams have come to use the Fibonacci Scale for business. When managing a team, it’s often important to estimate how long it might take to complete a given task. More complex tasks are assigned more points, and smaller tasks are assigned fewer points. Managers can then review and prioritize tasks depending on their points. The Fibonacci Scale is used to assign those point values.

What is the significance of the numbers in the Fibonacci Scale?

The numbers in the Fibonacci Scale are based on the Fibonacci Sequence. In this sequence of numbers, each number is the summation of the two previous numbers. In the context of Scrum, the numbers represent the level of complexity and degree of difficulty involved in completing a task. For example, a task assigned “0” points would be very simple and quick to complete, a task assigned “1” point would be slightly more complex or time-consuming, and so on and so forth. Since the scrum approach generally works in one-week sprints, it’s unlikely that many tasks will be assigned “21.” 

Why use the Fibonacci Scale?

The Fibonacci Scale is a useful tool for a variety of reasons. For one, it’s exponential. When estimating how long it might take to complete a task, it’s much easier to estimate time for shorter tasks than to estimate time for longer tasks. An exponential scale reflects that growing uncertainty. As you move up the scale, the numbers become much larger very quickly.

Relatedly, the Fibonacci Scale forces your team to make a choice. For example, when estimating time for a complex task, you ask “is it an 8, 13, or 21?” and there is no in between. This is an intuitive anchoring mechanism that cuts down on debate and helps you make clear judgment calls.

Overall, the Fibonacci Scale is a powerful method to ensure that work is distributed evenly and can help ensure that everyone is accurate when estimating the work and time involved in a project. If your team uses this approach on an ongoing basis, you are likely to become more accurate and avoid overcommitting during each sprint.
