Introduction to Agile Development 

Agile development has revolutionized the way software is built and delivered. It emphasizes flexibility, collaboration, and iterative development to deliver high-quality products. One key aspect of agile development is accurate estimation, which ensures that teams have a realistic understanding of the effort and time required to complete each task. Estimation poker, also known as planning poker, is a popular technique used in agile teams to improve the accuracy of estimations. By leveraging the collective wisdom of the team, estimation poker helps in making informed decisions and setting realistic expectations. 


The Importance of Accurate Estimation in Agile 

Accurate estimation is vital in agile development as it enables teams to plan and prioritize effectively. Correctly estimating tasks helps manage expectations and ensures timely delivery. It also facilitates efficient resource allocation, preventing team members from being overburdened or underutilized. Accurate estimation provides stakeholders with a clear understanding of project timelines and facilitates effective decision-making. Moreover, it fosters trust and transparency within the team and with external stakeholders. 

What is the Poker System in Agile? 

The poker system, also known as planning poker, is an estimation technique widely used in agile development. It is a collaborative and gamified approach that involves the entire team in estimating the effort required to complete a task. The poker system derives its name from the use of playing cards, which represent different levels of effort or complexity. By leveraging the collective knowledge and experience of the team, the poker system helps in arriving at a consensus on the estimated effort. 

What is Poker Method of Estimation? 

The poker method of estimation is a technique where each team member independently estimates the effort required for a task. The estimates are then revealed simultaneously, and any discrepancies or differences are discussed. Through this discussion, the team works towards a consensus estimate. This method ensures that one person’s bias or opinion does not dominate the estimation process. It encourages active participation and collaboration among team members, leading to more accurate estimations. 

Why is it Called Planning Poker? 

Planning poker gets its name from the use of playing cards during the estimation process. Each team member is given a set of cards with values corresponding to different levels of effort or complexity. The cards typically follow the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21, etc.) to represent increasing levels of effort. The use of cards adds an element of fun and gamification to the estimation process, making it engaging and interactive for the team. 

How Estimation Poker Works 

Estimation poker is a simple yet effective process that involves the entire team. Here’s how it works: 

1. The product owner or scrum master presents a user story or task to the team. 

2. Each team member independently selects a card from their deck to represent their estimate of effort or complexity. 

3. Once everyone has chosen a card, the estimates are revealed simultaneously. 

4. If there is a wide discrepancy in estimates, the team engages in a discussion to understand the different perspectives and factors influencing the estimates. 

5. After the discussion, the team re-estimates the task by selecting new cards. 

6. The team continues discussing and re-estimating until they reach a consensus estimate.

7. The final estimate is recorded and used for planning and prioritization.

What is Planning Poker Estimation Technique? 

Teams use the planning poker estimation technique, also known as estimation poker, as a collaborative approach in agile development to estimate the effort required for each task. It leverages the collective knowledge and experience of the team to arrive at a consensus estimate. The technique incorporates elements of gamification and encourages active participation from all team members. By using the Fibonacci scale, planning poker ensures that estimates are based on relative effort or complexity, rather than absolute values. 

What Metric is Used to Estimate with Planning Poker? 

Planning poker utilizes the Fibonacci scale as a metric to estimate the effort required for each task. Moreover, the Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones (1, 2, 3, 5, 8, 13, 21, etc.), serves as the basis. In planning poker, each number in the sequence corresponds to a playing card. Subsequently, team members select a card representing their estimate, and they reveal the cards together. The use of the Fibonacci scale allows for a non-linear progression of estimates, reflecting the inherent uncertainty and complexity of software development.

Benefits of Estimation Poker 

Estimation poker offers several benefits to agile teams. Firstly, it enhances accuracy by involving the entire team in the estimation process, leveraging collective knowledge and experience, resulting in more precise estimates. Additionally, accurate estimates facilitate efficient resource allocation, ensuring that team members are neither overburdened nor underutilized. Furthermore, estimation poker fosters transparency and trust within the team and with stakeholders by making the estimation process collaborative and inclusive. Moreover, accurate estimates empower teams to plan and prioritize effectively, ensuring they complete tasks on time and within budget. Lastly, the gamified nature of estimation poker engages team members and encourages collaboration, leading to a more productive and cohesive team.

Implementing Estimation Poker in Agile Teams 

To implement estimation poker in agile teams, it’s essential to follow these steps. Firstly, introduce the Concept by explaining the concept of estimation poker and its benefits to the team, ensuring that everyone understands the process and rules. Secondly, provide Training by conducting training sessions to familiarize team members with the estimation poker technique and the use of the Fibonacci scale. Next, create a Consensus by encouraging open discussion and collaboration during the estimation process to reach a consensus estimate. Furthermore, iterate and Improve the process continuously by evaluating and refining it based on feedback and lessons learned from previous estimations. Lastly, Promote Participation by ensuring that all team members actively participate in the estimation process and feel comfortable sharing their perspectives and insights.

What is the Fibonacci Scale in Planning Poker? 

The Fibonacci scale is a sequence of numbers where each number is the sum of the two preceding ones. In planning poker, the Fibonacci scale is used to represent increasing levels of effort or complexity. The scale typically starts with 1 and follows the sequence 1, 2, 3, 5, 8, 13, 21, and so on. Each number corresponds to a playing card used during the estimation process. The Fibonacci scale allows for a non-linear progression of estimates, reflecting the inherent uncertainty and variability in software development.
