I was thinking about writing a question along the lines of "What strategies are there for creating X?" where "X" would be a specific type of puzzle. The problem of course is that as is, that type of question is almost certainly too broad. To make it more suitable, I'd almost certainly have to narrow the scope of the question down.
Possibilities that come to mind:
Narrow it down to "What strategies are there for creating X given restriction Y?".
A good restriction can make this type of question much more manageable, but not all restrictions result in a suitable question. For example, while "What strategies should I use for creating checkmate puzzles" is narrower than "What strategies should I use for creating chess puzzles", the question itself is still too broad.
Narrow down to "What strategies are there for <certain aspect> of creating X?"
Probably more feasible, especially when you can break down the creation process into discrete parts. Like the former, I can see multiple different questions about X, each with a specific aspect, but that's probably a good thing.
The reason why I'm not currently satisfied with what I've come up with is that it could potentially become a question that's primarily opinion-based.
Is that just a line that I'm going to have to constantly watch, or is there an alternative way of presenting puzzle creation questions that doesn't have the same pitfalls?
