There is a subtle difference between resolving an issue and fixing a problem.  If the issue has a solution, in essence it is settled.  That particular issue is finished.

On the other hand, the problem from which the issue arose is probably not solved.  In this case it is highly likely similar issues stemming from the base problem will contine to arise.

Applying Common Sense

Given fixing the problem will address reoccurrence, it clearly reduces work, re-work and associated costs and reputational impacts.

So, when you are presented with an issue, investigating to determine the problem (aka cause of the issue ) and then fixing it seems to be more logical than fixing related issues ad infinitum.

If it was so Easy

Typically most of us focus on the issue.  The most common question that springs to our mind is, “What is wrong? and How can I resolve it?”, not “Why is this happening?”.

There is of course a sense of urgency and it often seems the value of determining why an issue occured doesn’t outweigh the value of putting the issue to bed quickly.

If the issue reoccurs, (or a similar issue) odds are you won’t even recognize the relationship because you have not associated cause.

The sad part is just shifting the question from how to solve the issue, point in time, to how to fix it permanently is not difficult.  It is however not intuitive so often gets by passed.
