The table of two values, Behaviour and Structure!

The table of two values, Behaviour and Structure!

Is it more important for the software system to work or is it more important to be easy to change? If you ask the business managers they will say work is more important, some developers also go along with this attitude but that’s the wrong attitude.

Why the wrong attitude?

  1. If you give me a program that works perfectly but impossible to change, it means it won’t work when the requirements change.
  2. If you give me a program that does not work but easy to change, it means I can make the change to make it work.

If you’re a programmer with the attitude (1.) then one day your system will reach to the point where the change will be impractical (cost of change will be unaffordably high).

Eisenhower Matrix

Eisenhower said, I have two kinds of problems, the urgent and the important, where the urgent are not important and the important is never urgent.

when it comes to software, The first value of software is behavior, is urgent but not always important. The second value is architecture, is important but never urgent. Of course, some things are not urgent and not important.

  1. Urgent and important
  2. Not urgent and important
  3. Urgent and not important
  4. Not urgent and not important.

Mistakes that business managers and developer make is to elevate items in position 3 to 1. It means they always fail to separate those features that are urgent but not important from those features that are really urgent and important and this failure leads to ignoring the important architecture of the system in favor of the unimportant features of the system.

So if you are a software developer, you are hired to maintain the quality and structure of the system and only you know the importance of the architecture.
