Though refactoring can be beneficial for business, it should be done carefully. There are instances when refactoring can be significant and when it should be avoided. In this article, we have mentioned how to deal with refactoring in Scrum. Continue reading!
When Should a Code be Refactored?
You have to understand the fact that every business is about generating value. Let’s face it, nothing is done for fun in the business environment. Through Scrum, you can improve the quality of your work and increase productivity.
Adding New Features
A product that is labeled as done should not have any technical debt. In case you think by adding a new feature the current code will be impacted, then it should be refactored. It is advised to include the cost of refactoring on the Backlog. It is even crucial to explain this to your Product Owner.
This is an important thing to do because its Product Owners responsibility to prioritize the items. It will be up to the Product Owner to decide whether it is worth it or not. However, this should not be a long-term strategy as it will kill the team speed.
Sometimes, developers don’t have much time, and they end up writing harmful codes. This gives rise of bugs; fixing the bugs might take too much time and effort. There are chances the problem of bugs might be Code Smell. So, it is better to refactor the code before you fix the bugs.
If unhealthy patterns such as duplicate code, large classes, tight coupling, or long methods are detected, you must refactor the code.
When Refactoring Should Be Avoided?
There are times when refactoring might not be a good option as it might do more damage than good. Here are some situations when code should not be refactored.
- When a new development is being planned, and the deadline of the existing project is near.
- If the code is stable
- In case you don’t have the time to test the refactored code, then it must be avoided. This is because it can create bugs.
- When the cost of refactoring is higher than rewriting code from scratch.
- Delayed refactoring should be avoided as it can create a huge mess. This might even be challenging to refactor the code. So, it advised refactoring the code as soon as possible.
Goals of Refactoring
The primary purpose of refactoring is to make it easy to maintain and enhance in the future. Through refactoring, you can get rid of future defects, bad coding is appropriately restricted, and the code size is decreased.
Hence, code refactoring is a beautiful way to remove code smells. This will help in making programs run faster, enhancing the design of the software, finding bugs, and making it easy to understand the code. So, depending on the situation, the code is refactored.
