Key principles in software development

The great things survive despite of time, so do key software principles.

In development process, these principles give the instructions to build a high-quality product in a limited time by using resources efficiently. Both individuals and big-size teams can apply them.

DRY - Don’t Repeat yourself

Every small pieces of knowledge may only occur exactly once in your entire system.

A small piece of knowledge must have a single, unambiguous, authoritative representation within a system.

Keep the followings in mind to achieve DRYness.

KISS - Keep It Simple stupid

It is not just applied to software world. It is all about simplicity.

In software development, there are many people involved in the conceptual process, who do not have the technical expertise to make a reliable cost-benefit analysis. Hence, they don’t see the problem. Double-check the requirements whether they are really stripped down to the essence that the client needs. Take the time to discuss critical points and explain why other solutions might be more suitable.

Finally, try to think out-of-the box if a task looks complicated to you. If someone is explaining to you his requirements, and you are thinking that it’ll be tough and complex to implement, you are right under almost any circumstances.

YAGNI - You Aren’t Gonna Need it

If it is not in the concept, it is not in the core.

YAGNI asks you to reduce the number of components.


All of them strives for a simple solution and reduces complexity by different approaches.
