I would suggest you look into one of the Thinking Process tools from the TOC body of knowledge. The Transition Tree is a tool conceived in order to give clear instructions, and therefore to develop those instructions.
We start realizing that "as long as we don’t know how to verbalize our intuition, the only thing we can delegate is our confusion." The Transition Tree answers the common questions that we usually ask ourselves when a task is assigned to us.
Why are you asking me to do step X ?
When do I do step X ?
When do I know I have successfully completed a step so I can move to the next step ?
What is the objective we’re trying to achieve ?
What is the objective of each step ?
Why do step X before step Y ?
How do I know when I have finished ?
Why do you claim that step X will achieve its purpose ?
The Transition Tree is typically built in the formo of a logical cause-and-effect tree that contains the following elements:
The need for the action
The action itself
The explanation for why the action will fulfill the need
The result of the action
Why the next step is needed
There is more information on the Transition Tree at this link to a description of the Thinking Processes or this link on how the Thinking Processes are used to deal with resistance to change.
In a project management context, the Transistion Tree is also very useful for developing sets of activities/tasks where the exact process is currently unknown or where the close following of those tasks is necessary to assure successful completion of the effort.
