Your writing is good, please keep at it. I think it would help a lot if you made it clearer when you're talking between root-cause-analysis for software, aviation, other things, or generically.

Also, your train-of-thought is pretty deep; bulleting runs out of steam and gets visually confusing, especially with the article table-of-contents on RHS, you're only using <50% of screen width. Suggest you need numbered/lettered lists and section headings and use the full screen width.
