Looking at the software industry as it stands, it would accurate to assume that most working in it don't know what technical excellence is; software maintainability is seemingly non-existent, and technical debt often rampant. If you look at the distribution of cost associated to a software project you will see that 80% of costs are accumulated after a project's initial release. This would mean that software maintainability is a crucial element of any sort of technical excellence.
But if you ask a developer what they are doing to increase their software's maintainability, you probably won't get the answer you're looking for.
This is because software maintainability is not often central to any computer science curriculum or professional development environment. It has not been until recently that the industry is beginning to see the value in writing maintainable code.
If you read through most our posts on the site you will see a trend when speaking about the consequences of technical debt. The more technical debt you have in your software the harder it is to keep your system running smoothly and the more difficult it is to make changes to it in order to keep up to customer and industry demands. Technical debt is directly at odds with software maintainability.
So how do you deal with this?
The author of this post boils it down to writing CLEAN code.
This aren't the only factors you need to pay attention too when writing code, but they are the most recognizable and easiest to understand. Again, if you go through our previous posts you will see persistent mentions of these qualities: specifically encapsulating code so that problematic sections won't be tethered to the whole product and inhibit progress in the future. Ultimately, the name of the game is building software with high code quality standards so that you can always meet the needs of the user and adapt to future demands.
