Personally, I think through writing. My first draft is what I write to help me understand a problem or an idea. That's good for me, but not so good for you. Useful writing addresses someone else's need. The questions are "who is your audience?", and "What do they need to know from you?" Writing for other people is communication. What are you intending to communicate? Technique, as illustrated in this article, serves that intention.

Cole Nussbaumer Knaflic's book "Storytelling with Data" is a good book on technical communication. TLDR: it's a process, and it's not about you, it's about them.
