When you read something, all of it is right there on the page or screen. 100% of the art is present and can be evaluated, analyzed, and understood.

This is not true of most other things in this world, including other types of art. In other art forms the artifice can and often does conceal the structure, but with writing it never does.

Of course, even with writing, what you don't see is the process that was used to achieve the finished product: edits, deletions, false starts, things thrown away entirely, etc.

But the effect and the way that words were used to create that effect are all in front of you.

The thing with a writing process is that you need to develop one. How do you write? How do you start? How do you edit? Who helps you? What are your sources of inspiration?
