The Fibonacci scale is a set of exponentially rising numbers that may be used to estimate the amount of work necessary to finish a job or execute a user narrative. To prioritize work for the next sprint, agile teams review forthcoming tasks and give points to each one using the Fibonacci scale. Complex jobs get more Agile narrative points, whilst lesser tasks receive fewer. In Agile, Fibonacci provides teams and project managers with a practical manner to approach story point estimations. The amount, complexity, and work required to finish a user narrative are represented by tale points.

**What is the Fibonacci Sequence ?**

The Fibonacci scale is a set of numbers that increase exponentially in order to estimate the work necessary to finish a job or execute a user narrative.

To prioritise work for the next sprint, agile teams review forthcoming tasks and give points to each one using the Fibonacci scale. Complex jobs get more Agile narrative points, whilst simpler tasks receive fewer.

Based on the Fibonacci sequence, the Fibonacci scale consists of numbers that sum up the two previous integers, beginning with 0 and 1. The Fibonacci sequence is composed of the numbers 0, 1, 2, 3, 5, 8, 13, 21, 34, 55, and 89.

**Why is the Fibonacci sequence used in Agile?**

The Fibonacci sequence may be found in nature and in many different areas. It has been used to explain plant development, estimate population expansion, model viral outbreaks, and forecast financial market behaviour. But how does this relate to Agile planning?

Essentially, Fibonacci in Agile provides teams and project managers with a reasonable manner to approach story point estimations.

The quantity, complexity, and work required to finish a user narrative are represented by tale points. Each narrative point is assigned a number from the Fibonacci sequence. The greater the number, the more difficult the plot point and the greater the work required to fulfil it.

**How Does Fibonacci Agile Estimation Work in Practice?**

There are various methods for calculating tale sizes in points. Typically, the product owner or manager gets together with the team to estimate user stories using the procedures outlined below:

1- Each team member assesses the magnitude of the work using the Fibonacci scale.

2- All team members share their figures at the same time to prevent being affected by each other’s estimations

3- They evaluate the revealed data together until they reach an agreement on each assignment and user narrative.

4- Each user tale is then assigned to a bucket that corresponds to a position in the Fibonacci sequence.

The team performs these procedures for all user stories and outstanding tasks to be added to the product backlog.

The planning poker approach is another popular way for Agile teams to estimate story points. This method entails distributing card decks with numbers in the Fibonacci sequence. The product owner or manager distributes a deck of cards to each team, and the estimation process begins with an overview of a user story.

The group discusses the narrative, asking clarifying questions. After that, they choose a card to symbolise their estimate and set it face down on the table.

Team members hands over their cards at the request of the product owner. If everyone chooses the same number of cards, that number becomes the estimate, and the team goes on to the next story. If the figures disagree, individuals whose estimates are much higher or lower are asked to defend their choices until everyone reaches an agreement.

**Can you use a modified Fibonacci scale?**

As long as the modified Fibonacci sequence rises by more than 60%, the exercise will likely provide comparable outcomes as the traditional Fibonacci series. The 60% limit is derived from Weber’s law of visible differences, which states that humans are more likely to notice the difference between two things with considerably different weights than two with just a tiny weight difference.

You may use a modified Fibonacci sequence that begins with a number other than 0 or 1. You may also start at 0 and 1 and double each number, for example, 1, 2, 4, 8, 16, 32.

Whatever modification approach you use, make sure that your team’s conversations are focused on accurately analysing each user narrative and not on the changed Fibonacci sequence.

**What are the benefits of applying the Fibonacci scale in Agile?**

The Fibonacci scale is useful in Agile contexts for various reasons. Its exponentially growing nature makes it easier to distinguish between basic and complicated jobs, allowing teams to make sound decisions. Other advantages of using Fibonacci in Agile include:

**1. Fostering cooperation in cross-functional teams:** Fibonacci estimating methodologies necessitate that team members contribute their opinions, experiences, and knowledge to the implementation of forthcoming user stories. This improves the accuracy, collaboration, and realism of the project estimating process. To estimate the time necessary to construct a new landing page, for example, you will need the involvement of your UX, design, development, and content teams.

**2. Creating a scale for comparing user story points:** Fibonacci estimating methods give a reliable method for determining how much weight each user narrative carries. Because of the Fibonacci sequence’s exponential nature, teams can easily comprehend what the allotted numbers signify and how difficult it may be to execute a certain assignment. A 0 or 1 indicates that the plot point is basic and can be finished quickly. An 8 or 13, on the other hand, indicates that the plot point is more difficult and may take weeks to complete.

**3. Improving the accuracy of estimates in project planning:** Using the Fibonacci scale in Agile settings allows team members and project managers to fairly assess the work necessary to accomplish each job in a sprint cycle. This results in more precise estimations throughout the project planning phase.

**4. Increasing team involvement and engagement:** Using the Fibonacci scale ensures that work is effectively dispersed within and across teams. By soliciting team members’ thoughts throughout the sprint planning stage, you can guarantee that everyone is on board with the planned timescales and ready to collaborate to see the project through to completion. If you apply this method on a regular basis, you will improve your forecasting accuracy and prevent overcommitting throughout each sprint cycle.

**What are the challenges of applying the Fibonacci scale in Agile?**

The disadvantages of employing the Fibonacci scale in Agile are minor in comparison to the benefits.

For others, employing a Fibonacci-based narrative point system might be perplexing – the growing sequence of numbers can go against our brain’s regular preferred method of counting and calculating.

When employing Fibonacci, it is recognised that the figure in the series grows in proportion to the task’s uncertainty and complexity. When a job is given a high number in the sequence, it might become too complicated to make any type of correct assumption about it. Using a different technique may make estimating complexity in this kind of circumstance simpler.
