I like to ask my colleagues often, brainstorm a bit with them etc when solving problems. Usually after pondering the issue a bit I get an idea of what a good solution would be, but often I can get valuable input from my coworkers.

Maybe I've missed an important corner case. Maybe my coworker has worked on something similar or relevant and has some code or technique I could use. Maybe I've been overthinking it and a stop-gap is better until we can make a more informed decision.

Sometimes just a tweak can make a significant difference, other times I end up going a completely different route.

I'll also email or phone customers if I sense a X/Y problem, or if I don't fully get their feature request or bug description. I'm not a domain expert and it's good to have context.

All in all, indeed it's usually a good idea to not jump straight into it. Mull it over, talk a bit with someone.
