Relativity & Story Sizing

In the realm of Agile development, accurate estimation is crucial for project success. As we dive into the fascinating world of story sizing, an interesting parallel emerges between the theory of relativity and the agile practice of estimating.

Let's explore how Einstein's theory of relativity aligns with story sizing.

What is Relativity:

Albert Einstein's theory of relativity revolutionized our comprehension of space, time, and gravity. It revealed that measurements of these dimensions are not absolute, but rather depend on the observer's frame of reference. It prompts us to question the concept of absolutes and embrace the concept of relativity.

" IN THEORY, THEORY & PRACTISE ARE THE SAME. IN PRACTICE, THEY ARE NOT" - Albert Einstein

Embracing Relativity in Story Sizing

Within Agile methodologies, story sizing serves as a pivotal technique to estimate the effort required to complete user stories. Applying the principles of relativity to story sizing introduces a powerful perspective that can enhance our Agile practices.

Relative Estimation

Like relativity, story sizing involves relative estimation. Instead of fixating on absolute measures, Agile teams assign story points based on the relative complexity, effort, and risk associated with each user story. This allows for a more contextualized understanding of the work at hand.

Frame of Reference

Relativity acknowledges that observations are shaped by the observer's frame of reference. Similarly, story sizing recognizes that each team member brings a unique perspective, knowledge, and expertise. By embracing these varied viewpoints, Agile teams can collaboratively determine story sizes and foster a shared understanding.

Iterative Adaptation

Relativity emphasizes the iterative refinement of observations based on new insights. Similarly, story sizing in Agile is an iterative process. As teams progress through sprints and gain more information, they adapt their estimations, fostering continuous improvement and accuracy.

Benefits of Relativity in Story Sizing

• Collaborative Decision-Making: Relativity encourages Agile teams to engage in collaborative discussions during story sizing sessions. The value of estimation lies in the discussions. By leveraging the collective knowledge of team members, estimations become more accurate, leading to better planning and resource allocation.
• Flexibility and Adaptability: Relativity provides Agile teams with the flexibility to adjust story sizes based on changing project dynamics, evolving requirements, and new information. This adaptability enables teams to respond effectively to shifts in priorities and optimize their work. In principle we have our definition of 1 and all other stories are relative to the 1. Changes made to the definition/ understanding of 1, course correct the teams estimates.
• Continuous Learning: Embracing relativity in story sizing fosters a culture of continuous learning. By reassessing estimations and comparing them with actual effort expended, teams gain valuable insights to refine their future estimations, improving accuracy over time.

By acknowledging the relativity of estimation, embracing diverse perspectives, and constantly adapting our understanding, we empower our teams to achieve greater accuracy, collaboration, and adaptability progressively.
