A learner may follow a live demonstration and still forget a step later. That is normal. A good training resource is there for the moment they return to the task alone.
I try to make resources easy to scan. Begin with the task and the expected result. Put steps in the order they occur. Show a relevant example and explain common mistakes. If a decision can branch, make the options visible rather than burying them in a paragraph.
The format should match the task. A quick reference may be better than a long slide deck for a repeated process. A short practice exercise may be better for a decision that requires judgment. An instructor guide can help keep live teaching consistent without forcing every facilitator to read a script.
The practical test comes afterward: can a person find the answer and do the task without asking the same question again? If not, the resource is an invitation to revise the instruction.
