What is a great software design?

I know everyone has their own opinion about what a great software design really is. For me, it’s rather very simple and be summarized in one sentence:

“A great software design can easily be changed in the future.”

In all of my designs, this is my primary goal in any architecture. Be very, very, careful of any library, frameworks, etc. you are thinking about adding. Do not add accidental complexity to your system because it saved you a few lines of code. Do not do it. Keep it simple before you start adding dependencies in your code. You will own this dependency for a long time.

If you are starting a greenfield project, start simple and stay simple until you have no choice and add additional complexity. Resist the temptation of adding this “cool” library or framework.

So, remember, “A great software design can easily be changed in the future.” Stick to your software architecture and stay disciplined and avoid feature-creep in the design. Don’t cut corners and let the team members know that it is important to keep the design simple.

There is enough complexity to deal with because you are creating software. Concentrate on the Ubiquitous Language. Make sure you see that language in your code.

Well, enough rambling, just wanted to write down some thoughts and to remind myself as well.
