5 Best Practices of Software Engineering in 2021

Thanks to the science and art of programming, today, we can use various devices and programs that simplify our life, make them more convenient and help solve everyday problems.

In this article, we’ll look at the best guidelines for adopting the best practices of the software development industry.

Why is best practice in software development a hot topic?

Software developers understand that standardized coding conventions help keep code up-to-date and valuable for customers, prospective developers, and coders themselves. Any experienced programmer spends most of their time reading code, not writing it. 

You are more likely to work on existing code than to write something from scratch. Therefore, your code must be easy for other engineers to understand.

Best Practices of Software Engineering in 2021

1. Good code readability

All dedicated software developers know that the most important thing is always writing code that will be easy for others to understand. Writing highly optimized math routines or building complex libraries is relatively easy. Writing 200 lines of code that another software engineer can immediately understand is more challenging.

When you come back for a code update, it will make your life much easier. In addition, the debugging process should be smoother for you or for other engineers who need to edit your work.

2. Development methodologies

You cannot create large projects with large amounts of data in chaos. It is better if you have a methodology. One can argue about what it should be, but it is not a matter of dispute.

There are those, for example, who genuinely believe that we cannot create good software without the flexibility of agile methods. Others put agile aside because it is too capricious and arbitrary.

Statista reports that around 36% of respondents mentioned utilize DevOps methodologies and approaches during software development in 2021. DevOps stands for combing IT operations and software development.

It aims to provide continuous delivery by shortening the systems development cycle while ensuring high software quality. Reasons for choosing this method are faster time to market, security, code quality, and improved communication and collaboration among developers.

3. Code refactoring

Refactoring is about improving the structure of your code without changing its actual functionality. If you have multiple blocks of code that do similar things, converting them into a single function is helpful. It will allow you to simplify your code. And if you want to change the way that features works, you (or any other engineer) only need to update one feature, not a few.

Forbes writes that more experienced developers understand what a complete rewrite involves and how difficult it will be. Usually, more experienced engineers are encouraged to refactor because they know that even using scraps is better than starting from scratch.

4. Version control

Version control refers to a software development framework that tracks all changes and synchronizes them with the main file stored on a remote server. Using version control in a professional project gives the advantages of not losing the written code, having convenient access to the software for all developers, and introducing functions without affecting the work of other programmers. Professional software development company like MLSDev also has strict version control when developing its products.

5. DRY principle

Don’t repeat yourself DRY – aims to reduce repetition and duplication in the software development process. It is accomplished by replacing repetitions with abstractions or by grouping code into functions.

If your code executes the same instruction in 6 different places, it can be a real problem even for experienced engineers. It is much better to create a single function that executes the statement once and will refer to that function whenever needed.

Some Extra General Tips

Assign appropriate names to all functions, variables, and methods because it makes your code simpler, understandable, and easy to debug.

Always use the developer’s common or native language for names and descriptive texts. Avoid abbreviations whenever possible to reduce ambiguity.

Use consistent indentation and alignment when formatting your code for better readability.

Conclusion

The techniques described will help you code more efficiently, but they will also increase the awareness of the software development community about responsible coding. These simple steps will put you on the same footing as the best developers and coding masters. And they will also make you real professionals in their field!
