| Good article. Tech writer for too many years here: I agree with the 4 doc model. It boosts a proven structure for individual pieces of a doc set. DITA formalizes this with its topic, concept, and task, and reference topics. You see another form of it in man pages. And I agree with the FTA, it's often overkill or just plain unsuitable. If you're stuck with writing anything from a readme to an aircraft maintenance library, then you can make your content engaging and useful by just making sure that it's correct, clear, concise, consistent, and cohesive. Above all it should be compassionate[1]. Check off those 7 C's and your doc will be appreciated. The 4 doc model is just one option to get you there. [1] https://egopontem.com/blog/7cs |
