data analysis steps

As someone who never worked in such business, I already know the steps to do the analysis but I am not always full aware of what to be included in my solution, for example I might fotget to put a client filter on my dashboard. 

is there a way to check how valiable  and useful my analysis without consulting others, or this is something people develope at work.

I want to also know if someone like you can do a perfect analysis and dashboard even in unrelated fields of your study.

thanks.
