Today, weβre diving into the concept of severity in bug management. What does severity mean in this context?
I think it relates to how serious a bug is?
Exactly! Severity measures the technical impact of a bug on the application. For example, a critical bug might cause the app to crash. Can you think of any scenarios where this could happen?
Maybe if thereβs an error in the code during login?
Great example! An app crashing on login is classified as a critical severity issue. Remember, severity ranges from critical to trivial. Letβs recap: Critical issues halt functions, while trivial ones are minor annoyances.
Understanding Priority

Now, letβs switch gears to priority. How is priority different from severity?
Isn't priority about how quickly we should fix an issue based on business needs?
Exactly! Priority tells us how urgently a defect needs to be fixed. For instance, a high priority issue must be addressed before release. Can anyone give an example of low priority?
A typo on a webpage? It looks unprofessional but doesnβt break anything.
Thatβs perfect! The typo might be trivial in severity, but itβs a low priority issue. Remember, a bug can be high severity but low priority based on the context.
Applying Severity and Priority

Letβs consider a few examples. If an app crashes when users submit a form without filling it out, how would you classify that in terms of severity and priority?
That sounds like a critical severity because it crashes the app!
And it might be high priority since users might hit that issue frequently.
Correct! Now, what if we had a layout issue that incorrectly aligns buttons but doesn't affect functionality?
That would probably be minor severity and low priority.
Right again! This exercise helps prioritize our focus on resolving defects efficiently.
Introduction & Overview

Quick Overview
Standard
Understanding severity versus priority is crucial in defect management. Severity assesses the technical impact of a bug, while priority determines the business urgency for fixing it. This section provides examples of critical, major, minor, and trivial severity, alongside high, medium, and low priority classifications.
Detailed
Priority Examples
In defect management, understanding the difference between severity and priority is essential for effective bug tracking and resolution. Severity refers to how significantly a defect affects the operation of the software, varying from critical to trivial impacts. On the other hand, priority indicates how urgently a defect needs to be fixed from a business perspective, which can also vary.
Severity Classifications:
- Critical: Issues that cause the application to crash or lead to system failure (e.g., app crashes on login).
- Major: Significant problems that affect functionality but do not crash the application (e.g., wrong calculation in invoice total).
- Minor: Lesser issues that donβt severely affect the application (e.g., UI alignment issues).
- Trivial: Minor defects that are cosmetic and can be tolerated for a period (e.g., typo in footer text).
Priority Classifications:
- High: Critical issues that must be addressed before release (e.g., fix required before launch).
- Medium: Important but can wait for the next sprint (can be scheduled in the next sprint).
- Low: Cosmetic improvements or issues that can be deferred (fix can wait for a future release).
Understanding these classifications allows teams to triage and efficiently allocate resources for resolutions. Careful consideration of the severity and priority of defects ensures that the most impactful problems are addressed promptly.

Detailed Explanation
The first example of priority is categorized as High Priority. This indicates that the fix for the defect is crucial and needs to be addressed immediately before the software is released. High priority defects could impact the functionality of the software or its ability to work correctly for end-users.
Examples & Analogies
Imagine you are running a restaurant, and the plumbing breaks. You cannot serve customers or keep the kitchen running efficiently until it is fixed. This situation is similar to a software issue that must be resolved before a product launch.

Detailed Explanation
The second example of priority is Medium Priority. This means that while the defect is important, it does not require an immediate fix and can be addressed in the next development cycle or sprint. It is still significant but can wait without causing major disruptions.
Examples & Analogies
Think of this like a minor leak in your roof. Itβs not an emergency and does not cause immediate problems, but if left unattended, it could lead to bigger issues down the line.

Detailed Explanation
The final example is of Low Priority. A low priority issue is typically a cosmetic or trivial concern that does not affect the core functionality of the software. These issues can be scheduled for future releases and are the least urgent among the defect categories.
Examples & Analogies
This is akin to having a small scratch on a car's body. It's noticeable, but it doesnβt affect the car's performance. Getting it fixed can wait until you're ready for a general maintenance check or when you have time.
