How do I turn problems I find into fixes that make sense?

You are good at finding what's wrong. Turning that into a fix people can actually use is a separate skill, and it is the one that makes your work count. Spotting the problem is the diagnosis; recommending the fix is the treatment, and the treatment is what changes anything. A good recommendation is not just the technically correct answer. It fits the real constraints: the budget, the people, the time they actually have. The best fix on paper is worthless if no one can afford it or carry it out. So ask not only what would solve this, but what this particular place could realistically do. Next time you flag a problem, force yourself to write the fix in one plain sentence, plus what it would take to do it. If it's too big or vague to act on, break it into the first step someone could take Monday. You will find that a small, doable fix beats a perfect one nobody moves on.
