Creative workflow
Creative workflow or design process, are a set of rules that each designers hold, much like a set of predefined actions. I see some designers searching the web for the "perfect for all" design workflow. In reality, unless you are the exact copy as another person, you won't find the perfect cure. And i'm not here to tell you how I create, but I can tell you how I came to a set of my own workflow:

It is the same simple concept of drawing an egg ~ when I studied the foundations of drawing from grade level, we were taught to draw nothing but eggs in different shades & angles. To first copy, then create. If we can't copy & understand the basic forms of an egg, how can we use that form to create.
Devour books, interviews on other successful creatives, remember their names, learn their workflow ~ keep only the best, then throw away those doesn't comply to us, our budget, our personally, our way of creative thinking. Repeat this process steadily, over the years, it is through this process of elimination & constant learning, we improve & enforce our own set of design workflow. This skill is not taught in any school nor explained in any single book.
