Bad code can have a significant impact on the growth and success of a software product. In fact, bad code can be so detrimental that it can lead to the downfall of entire companies. For example, in the late 80s, a company wrote a popular app that was used by many professionals. However, as the company added more features, the code became increasingly worse, leading to longer release cycles, more bugs, and increased load times. Frustrated users eventually stopped using the app, and the company went out of business shortly after.
Similarly, in 2018, a major airline experienced a system outage that led to the cancellation of thousands of flights and cost the company millions of dollars. The root cause of the outage was traced back to bad code that had been written years earlier and had not been properly maintained. These examples demonstrate the importance of writing clean, maintainable code and the consequences of neglecting code quality. By prioritizing clean code practices, companies can avoid costly mistakes and ensure the long-term success of their software products. So let's look at the attributes clean code should have:
- Clean code is easily readable and understandable.
- Clean code is simple and direct with minimal complexity.
- Clean code has consistent formatting with indentation, spacing, and line breaks.
- Clean code uses meaningful names for variables and functions.
- Clean code includes proper comments and documentation.
- Clean code handles errors gracefully and according to an articulated strategy.
- Clean code avoids redundant logic and unnecessary intricacies.
- Clean code is organized into modular components or functions that perform a single, well-defined task.
- Clean code follows the single responsibility principle.
- Clean code is written in a way that other developers can easily modify and extend.
- Writing clean code significantly decreases defects, leading to a more stable product.
- Following clean code principles throughout a project gives it a unified, coherent feel.
- Clean code saves time by minimizing the need for re-coding.
- Clean code promotes modularization, breaking tasks into simpler, manageable components.
- Maintenance is easier with clean code due to its clarity and structure.
- "Clean code always looks like it was written by someone who cares." - Michael Feathers
- "The logic should be straightforward to make it hard for bugs to hide, the dependencies minimal to ease maintenance, error handling complete according to an articulated strategy, and performance close to optimal so as not to tempt people to make the code messy with unprincipled optimizations." - Bjarne Stroustrup
At Girmairi, we understand the importance of having software developers who can write clean code. Our software developers periodically go through assignments typically coming from books, documentation, or research papers. We also have an evaluation process that scores employees based on their knowledge growth. By providing our employees with the tools and resources they need to improve their skills, we can ensure that they are equipped to develop code that is rigorous, accurate, formal, and detailed. We make sure our software developers are fully prepared to face the challenges that come every day with the development process.
