Have one source of truth. For example, don't duplicate a procedure to separate out training content. Make use of the training notes, attachments, training objectives, and quiz functionality in AcceleratorKMS. We recommend that you only use a separate training content type when content is solely intended for training purposes.
If you do decide to create some content in AcceleratorKMS that is only for training, consider using a different style sheet and content type. That way, training content appears noticeably different to users and shows up separately in a content search. And if you have a need to track the creation or modification of training content, consider creating a separate workflow for that type of content.
