How to Handle Bugs Working In An Agile Environment?

 

This article highlights the strategies implemented to handle bugs and issues in an agile environment. You will learn different ways to manage bugs without affecting product delivery timelines and cost.

 

Delivering high-quality software isn’t easy when you have strict timelines and delivery cost. You need to maintain the quality by trading off it with time or budget. This tradeoff is depicted by an old rule called the Iron-triangle rule. According to this rule, the scope, cost, and time are interrelated factors for software development and critical to decide the quality of software.

How to manage bugs in agile methodology?

 

Agile methodology is about releasing frequent sprints that can quickly accommodate changes if any. Agile has a flexible scope defined in the product backlog. Scrum backlog has listed changes in the requirements to meet the new technology changes. Agile also requires higher customer involvement to check and validate the latest iterations.

 

There are two different approaches to fix bugs in an agile methodology.

 

  1. Classification of bugs 

 

It starts with understanding the severity level of bugs in the product.When a bug is identified in the system, the first step is to determine its criticality. It will give developers an idea about the impact it can cause to the entire product development. Testers also find the defect trends to track the nature and probability of bugs reappearing in the system.

 

The classification method of bugs varies in different organizations. There are five types of severity levels, such as:

 

Severity 1: Any bug that stops the user from performing the essential functions of the application, also it can leak their information to the outside world.

 

Severity 2: Any bug that affects the operational function of the application, and there are no solutions is available to overcome the error.

 

Severity 3: Any bug which affects the operational function of the application and there are acceptable alternatives available to fix it.

Severity 4: Any bug which causes inconvenience to the user and affects the functionality of the application.

 

Severity 5: All other errors.

 

There are four severity levels- critical, high, medium, low, or trivial in many organizations. A crash in-game has low criticality in comparison to any error in the flight control software code.

Another essential feature of fixing bugs is their priority. Prioritizing critical bugs can fix more bugs in less time-saving time and effort of developers. In agile methodology, low criticality bugs are often scheduled to fix in the end when time is available. Testers also use bug reporting software to log bugs and track their status. A tool also improves teams’ efficiency and collaboration on bug-fixing. 

 

Risk-based testing helps in finding and setting priority to bugs to ensure critical bugs are fixed first. A matrix is used to depict the impact and probability of the bugs. Testers often create this matrix to understand the severity levels and thus define the priority levels to the bugs.

 

2) Developing Bug-free Software

 

This strategy is implemented when the product is still in its development phase. Any error detected in the development stage is not a bug. If the error is able to pass to the production stage, then it becomes a bug. In agile methodology, new features are delivered fast, continuous development cycles for fast product deployment to end-user. The team requires continuous delivery to keep up the quality of the product. Agile releases a prototype or minimum viable product in the market to get quick feedback from the client. It helps in evaluating how each release can map to user expectations which can be taken as feedback to improvise the development process.

 

This approach also emphasizes on using test-driven development that has a unit test to verify code and its functionality. An automated test can also be used to test the build for faster feedback on the potential issues in the release.

 

Conclusion

 

In agile projects,  bugs are fixed before production. Agile teams also use collaborative tools to recognize defects and to mitigate them quickly. It reduces the teams’ effort to bring high-quality software to market.
