discuss how the Sprint Backlog can be changed without endangering the Sprint Goal.

It consists of the tasks to be accomplished within a particular sprint, derived from the product backlog items selected for that Sprint. Unquestionably, the Sprint Backlog is mutable. The Sprint Goal, however, is not. The Sprint Goal defines the objective that is met through the implementation of the product backlog. The alteration of the Sprint Backlog should not be detrimental to the Sprint Goal. This article sheds light on how amendments in the Sprint Backlog can be executed without posing a risk to the Sprint Goal.

1. Understanding the Distinction Between Sprint Goal and Sprint Backlog

It’s important to understand the distinction between Sprint Goal and Sprint Backlog to grasp how changes in the latter will not necessarily affect the former. The Sprint Goal is the overarching objective which the team must fulfill by the end of the Sprint. On the other hand, Sprint Backlog is the list of tasks the team decides to work on in a given Sprint to realize the Sprint Goal.

Let’s assume the Sprint Goal is to “improve the website’s user interface.” The related tasks for this goal in the Sprint Backlog could be “redesigning the homepage,” “enhancing the site navigation,” or “optimizing the checkout process.”

2. Changing Tasks in a Sprint Backlog

Modification to the Sprint Backlog is a part of the Scrum methodology. This is changing the tasks, which can be ordinary and necessary. New found requirements stemming from the development process, ignored requirements, or change in the project approach can be the reasons for modification.

An example would be, considering the Sprint Goal mentioned above, if you realize a task like ‘redesigning the contact us page’ is pivotal to improving the user interface, it can be added to the Sprint Backlog. This addition doesn’t risk the Sprint Goal but supports it.

3. Ensuring Changes Don’t Threaten the Sprint Goal

Balancing adaptability and stability is the key. Changes in the Sprint Backlog should not result in entirely new Sprint Goals or compromise the ability of the Scrum Team to deliver a potentially releasable increment. When considering changes to the Sprint Backlog, they should be in alignment with the Sprint Goal.

Going back to our example, adding a task to the Sprint Backlog namely, ‘developing a new feature for the application’, may endanger achieving the Sprint Goal as it isn’t connected to improving the website’s user interface. Therefore, it’s essential to scrutinize every change and ensure it contributes towards the achievement of the Sprint Goal.

4. Use Emergent Strategy

Embracing an emergent strategy permits us to react to changes in the project environment without risking the overarching Sprint Goal. It helps in refining the scope and ordering of the backlog, and involves constant reassessment and adaptation based on the current understanding of the project.

As a Scrum Team, you may start with a clear vision of how to improve the user interface. But as development progresses, you may realize some tasks are more or less important, and new ones emerge. In that case, you apply your emergent strategy—keeping the Sprint Goal the same—to modify the Sprint Backlog.

In conclusion, Sprint Backlog changes and Scrum principles are not mutually exclusive.

The goal is to maintain the purpose of the Sprint Goal with nuance and awareness of the malleability of the Sprint Backlog. The Scrum team needs to be aware of the ever-changing demands and circumstances and must have the ability to adapt to these changes without compromising the ultimate Sprint Goal.
