We relaunched our website in early 2022 and started to talk about Clean Code—a term you may have casually used or heard before but may not have synthesized or internalized its true essence. 

We have recently discussed What Clean Code is

In this post, I will discuss why Clean Code is important and its power. 

The world runs on code

Software is at the core of every organization and is used to operate its business. Companies realize that the DNA of their software—the source code—is what really matters. 

It is the most valuable asset of software. Source code not only directs how the application will behave but also how it will perform. Keeping this asset clean will prevent it from becoming a liability. 

 Why Clean Code?

Clean Code benefits developers and organizations and makes it easier to introduce changes to the codebase producing software that is secure, reliable, and maintainable. 

Value for developers (all maturity levels): 

  • Boosts development skills
    • Helps developers detect, understand, and resolve issues as they code.
    • They learn best practices and enhance their skills through their development journey, making them better developers in the process – regardless of their experience level or seniority.
  • Increases efficiency and productivity
    • Reduces continuous rework and long feedback cycles as developers are equipped to do a good job from the ground up. This results in greater productivity.
    • When consistent coding standards are adopted, developers become more efficient and are able to meet their delivery expectations with speed and precision. 
  • Creates a great work environment
    • Enables developers to do a good job on the code they write or change. When code is clean, changes are easier to implement.
    • When less time is required to be spent on remediating someone else’s code, more time is freed up to work on innovative and interesting projects, resulting in happy developers, who continue to take great pride in their work.

Value for organizations (of all sizes and maturity levels) 

  • Reduces reputational and business risk 
    • Ensures fewer security risks by enabling teams to proactively address issues before they reach production.
    • Significantly reduces the occurrence of unanticipated application downtimes and costs due to issues that may stem from bad code.

  • Lowers code-level technical debt
    • Gradually addresses the debt of the overall codebase without the need for a massive application overhaul and disruption. 
    • Contained tech debt leads to the increased lifespan of the application.

  • Increases software development velocity
    • Clean Code standards and streamlined flows improve DevOps velocity – promoting faster time-to-market.
    • When development efficiency improves, team productivity boosts, and talent is retained as teams are able to focus on interesting projects and innovation that drive business value

Imagine a World of Clean Code

Would things be any different if your application’s source code consistently followed high standards?  

Maintenance time and costs would be drastically reduced

Not only that, but technical debt would be non-existent and the need to remediate would be absent. Making any change to the application would be so much faster. Instead of constant re-work, developers could be spending more time on innovation and solving interesting and important problems.

Developers’ work environment would be better

As code follows best practices, imagine how easy and pleasant it would be to own this source. Collective code ownership would become the norm–generating emulation and collaboration between developers. 

Developers spend most of their time reading and writing code, and having this code clean would mean a significant upgrade to their work environment. 

Software longevity would noticeably increase

A clean codebase would make it easier to introduce changes in a clear, readable and understandable way. No more tangled or rigid code and no more fear or frustration around it. The ‘soft’ attribute of code can continue to support changes in business without the need for it to be replaced (which can be costly and disruptive for organizations). 

Risks at runtime would be reduced

Operational bugs as well as late security vulnerabilities would not crop up when software is ready for production. This would significantly reduce the risk surface for organizations. 

Clean Code provides benefits for every stakeholder.  

Concluding thoughts on Clean Code

Software is eating the world. 

Keeping your code clean creates a better development and operational environment for everyone. Source code is your key asset – build it clean, clean it as you code – avoid it from becoming a liability. 

The Clean Code movement has begun and Sonar is leading the way.
