Actually, it still needs a lot of practice. When someone else can complete a project independently, then he must have a whole set of processes;

If you want to be such a person now, I suggest you master the scheme, design concept, tools (software) and so on in your mind to improve your communication and business ability; Every detail should be done to the extreme, all work is the same thing, when others admire, then you will succeed; Here I recommend a ppt with a soft design scheme that I found on the Internet. It is downloadable (enough for me) and has a lot of designer experience. I hope it can really help you.
