Today, let's discuss what a defect is. A defect is essentially a bug or error in a software application that deviates from expected behavior. Can anyone provide an example of what a defect might look like?
An example might be when I click the submit button, but nothing happens.
Or when an application crashes unexpectedly!
Exactly! Those are great examples. Remember, defects can result from features not functioning, poorly implemented requirements, or even mismatches between UI and expectations. Letβs keep these in mind as we explore further.

Can anyone think of situations when you should report a defect?
If a feature is supposed to work but doesn't, it should be reported.
Also, if there's a performance issue, like slow loading times, that should be reported too.
Correct! Factors like functionality failures, UI discrepancies, and performance issues are critical triggers for reporting defects. Always be on the lookout for these conditions. How can we track these defects once we've identified them?

Defect Reporting
Defect Reporting is a vital process in software development that involves documenting and communicating issues identified during the testing phase. A defect, also known as a bug, is a deviation from the expected behavior of the software as defined by its requirements or acceptance criteria.
What is a Defect?
A defect arises when there is a failure in the software to meet its predefined requirements or operational expectations. This can include scenarios where features do not function as intended, requirements are poorly implemented, user interface elements are inconsistent with user expectations, or performance issues arise.
When to Report a Defect?
Defects should be reported in several situations, including but not limited to:
- A feature does not function as expected.
- An implemented requirement does not match the specifications.
- User interface discrepancies from user story expectations.
- Any issues regarding performance, security, or usability.
To document these defects effectively, itβs crucial to use a defect report template that includes fields such as:
- Defect ID
- Summary
- Description
- Severity
- Priority
- Environment
- Screenshot
- Status
- Reported By
In addition, the role of Business Analysts (BAs) in defect reporting encompasses raising defects found during user acceptance testing (UAT), clarifying misunderstood requirements during defect triage, and engaging in retesting once fixes are applied.
By adhering to structured documentation and prompt communication, teams can ensure that defects are resolved efficiently, ultimately leading to higher software quality.

A defect (or bug) is a deviation from the expected behavior of the system, as defined by the requirements or acceptance criteria.
Detailed Explanation
A defect refers to any situation where the software does not work as intended based on the specifications provided. This could mean a feature does not behave as expected, or there is an error in how a requirement has been implemented. It's essential to understand that defects are not limited to just malfunctioning features; they can also include issues with performance, security, or usability that deviate from what was planned.
Examples & Analogies
Think of a recipe for a cake where it says to bake for 30 minutes. If the cake is burned because it was left in for too long, that's a defect. Just like in software, where expected behavior (cake baking time) should match the actual behavior (burnt cake).

β A feature doesn't work as intended
β A requirement is incorrectly implemented
β Thereβs a mismatch between UI and user story expectations
β Performance, security, or usability issues are found
Detailed Explanation
Reporting defects should occur at specific times during the software testing process. A defect should be reported when a feature fails to function as expected, when a requirement does not align with what was implemented, or when discrepancies arise between the user interface and user expectations. Additionally, any issues that may affect the software's performance, security, or accessibility should be reported to ensure a seamless user experience.
Examples & Analogies
Imagine you order a burger without pickles, but it arrives with extra pickles. This is a direct representation of a mismatch in expectations and reality. Just like food orders, software needs to meet user expectations and requirements; any divergence is something that needs reporting.
Defect Report Template (Fields)

Field Description
Defect ID Unique identifier
Summary Short title of the issue
Description Detailed steps to reproduce
Severity Impact on functionality (High, Medium, Low)
Priority Business urgency (P1 - Critical, P2 - Moderate, etc.)
Environment Where the issue occurred (Staging, Prod, etc.)
Screenshot Visual evidence if applicable
Status Open, Assigned, Fixed, Retested, Closed, etc.
Reported By Name of the person raising the defect
Detailed Explanation
A defect report contains several key pieces of information that help in identifying and resolving the issue effectively. These include a unique identifier for tracking the defect, a brief summary for quick reference, and a detailed description of how to reproduce the defect. The severity and priority fields assess how critical the defect is to the business and the current environment it was found in. Screenshots can aid in illustrating the defect, while the status indicates where the defect is in the resolution process.
Examples & Analogies
Consider a customer complaint form at a restaurant. It includes sections for the complainant's name, a brief description of the issue, the urgency of the complaint, and the current status of resolution. This structure helps ensure that the management can quickly identify and resolve issues, similar to how a defect report helps programmers fix bugs in software.

Detailed Explanation
In this example defect report, we can see how the fields are filled out to provide clarity on a specific issue within the software. The summary describes the problem succinctly, and the severity and priority help determine how quickly it needs to be addressed. The steps to reproduce the defect are crucial for developers as they provide a clear pathway to replicate and investigate the issue. The expected vs. actual results help in understanding what went wrong.
Examples & Analogies
Picture a tech support ticket, where you detail the problem you're experiencing with your internet connection. You provide your location, the type of router, and describe the exact issue. This kind of detail allows the technician to replicate the problem swiftly and effectively, much like a well-structured defect report does for software developers.
BAβs Role in Defect Reporting

β Raise defects found during UAT or requirement validation
β Clarify misunderstood requirements during defect triage
β Retest or support test case updates after fix is applied
Detailed Explanation
Business Analysts (BAs) play a crucial role in the defect reporting process. They are responsible for identifying and reporting defects during User Acceptance Testing (UAT) or while verifying requirements. BAs also help clarify any misunderstood requirements during discussions about defects, which is known as defect triage. After a defect is fixed, BAs may need to retest the functionality to confirm that the issue has been resolved, ensuring that the software now meets business expectations.
Examples & Analogies
Think of the BA as the liaison between a client (the end-user) and the engineers (developers). If a client complains that their new house has a leaky roof, the BA investigates this issue by talking to the client and reviewing construction plans. Once the builders fix the roof, the BA double-checks to ensure the problem is resolved, just as they would in software testing.
