Software developers are passionate and creative people, which impacts their thinking when writing software code. Depending on the kind of software, developers should use different approaches in order to make final product of a good quality.
I identify 2 main kinds of software - framework and application.
Framework is a software that is supposed to be distributed as a component for other development teams, so that it helps them implement better applications.
Application is a software that is supposed to be distributed as a product to limited kind of audience, so that it helps them execute their business-related tasks.
Ironically, I referred to "application" when defining "framework". This might be understood as a fact that the framework would not have any purpose if not applications that are going to use it.
When working on a framework, we should think about different kinds of software developers that we are targeting. Obviously, we are solving only particular tasks, but we are providing numerous different ways to do the same thing. This could be achieved by providing extensibility (expecting abstractions to be injected) or by providing many kinds of overrides for different methods.
So, in short, we need to use our creativity at a maximum. If not, our framework will not be attractive or useful enough.
When working on an application, we are focusing on particular problem domain. Our time is paid by a company that does not need to have a large contingency of never-ending things. We are concentrated on delivering product and functionalities needed by the company or a customer.
When I used word "over-creative", I mean that we write large number of code lines that we think might be useful in the future (but not now). If we do so, we will introduce following problems:
To sum up: when developing an application, limit yourself to the domain you are working on - solve domain-specific problems. Allow framework developers solve everybody else's problems.
Think big, do little. (I can't figure out who is the author, but I like this quote)
