This is the correct viewpoint (in my opinion, of course). There are many ways that lead to a solution, some are better, some are worse, some are faster, some much slower. Different tools and different strokes for different folks and if it works for you then more power to you. That doesn't mean you get to discard everybody for whom it does not work in exactly the same way.

I think a big mistake junior managers make is that they think that their nominal subordinates should solve problems the way that they would solve them, without recognizing that there are multiple valid paths and that it doesn't so much matter which path is chosen as long as the problem is solved on time and within the allocated budget.
