What Yagni Is?

Often developer debates a lot about what YAGNI is actually. Writing any new piece of code bind developer’s hand in the name of YAGNI.

I have worked in both product base company and service based company.I personally feel that YAGNI is more appreciated in the service based company, as in product based any extra feature is helpful.

People back YAGNI by saying “You don’t wipe before you shit.”.So true.We should not increase the scope of the problem as it may open the gates of new bugs.So YAGNI tells us “don’t write any extra/new code unless it is actually required”.

I agree with the last quoted statement.But should we bind our hands in implementing the requirement in a fashion that it should always be open for extensibility, or to write any functionality in a more generic way so that it can be reused any time in near future?

So, what my definition of YAGNI is: – Always write the code in the scope of the current requirement, but don’t cry out YAGNI if you want to solve it in the generic or extensible way.The code should close for modification but open for extensibility.

Try to solve problems in generic ways, that can be used in future.
