Our old system works, so why should we bother with code refactoring?

Your old system might still be functional, but refactoring isn't about fixing what's broken. It means making what's good even better and preventing future problems. Unrefactored code leads to higher maintenance costs, slower performance, difficulty adding new features, and a generally frustrating experience for both your team (especially when you hire new people) and your users.

Refactoring helps you avoid these headaches, improve your application's agility, and ensure it can adapt to future business needs without constant struggle.

How long does a typical code refactoring project take?

The duration of a code refactoring project depends on a few key factors:

  • Size and complexity of your existing codebase
  • Specific goals you have for the refactoring (are we just cleaning up, or also improving performance drastically?)
  • Technologies involved

Because every project is unique, we always start with a thorough code audit to understand your specific situation. Once we have that clear picture, we give you a detailed timeline and a clear estimate.

Will refactoring disrupt our daily business operations?

Our approach to code refactoring is designed to be as non-intrusive as possible. We work with your team to plan the refactoring process, often breaking it down into manageable phases. We utilize best practices for testing and deployment to ensure that any changes are validated before being integrated into your live environment.

Our aim is to conduct the refactoring in a way that allows your core business operations to continue, with planned downtime minimized and communicated well in advance.

What kind of results can we realistically expect after code refactoring?

You can expect significant improvements across several areas. Firstly, your application should become more performant and scalable, meaning it can handle more users and traffic efficiently. Secondly, you'll likely experience reduced development and maintenance costs because the code will be easier to understand and work with. This also leads to faster development of new features, as technical debt is cleared away.

You'll also see an improved user experience due to fewer bugs, better responsiveness, and a more consistent application. So, refactoring makes your software more robust, agile, and ready for future growth.
