99% of the time we assess what's happening in our life and make our plans using common sense but occasionally it's helpful to structure our thinking.
Domainal mapping is a tool I've found useful on several occasions. It allows you to understand a range of influences (often relationships) associated with a particular role in work or life and get a sense of perspective, as well as perhaps to identify some useful actions to help you progress.
I've used it most when I've either been feeling strain from change at work or I've been at some other turning point in my life. Google "domainal mapping" and you'll find a few articles about the technique, mostly focused on using it in very worky roles, but I tend to find that when I have decisions to make I need to consider what's going on outside work as well as within it. Mapping work and non-work "domains" alongside each other gives me a useful sense of perspective: "No wonder I'm stressed, look at all the crazy stuff going on!", or, "Hang on, I'm preoccupied with finishing that report and I really have other things to worry about - things that are more fixable.".
