Logically and linearly:

You give me the brief .

The detective work begins. I scurry off to my office, or camp out at yours,
for as long as it takes to become intimate with your business. I ask a lot
of questions, do a lot of interviews and bury myself in a mountain of information.

The writing process begins. I craft words, keeping in mind your objective, and your key audience.

The revisions process begins. Here's where you come in. After your feedback,
and some drafts to and fro, I go back to do the final tweaks.

Together, we can work wonders.
