Get the work you're delegating explained back to you
You’ve been thinking deeply about some work but you don’t have the capacity to do it all by yourself. So you are creating documentation for others to do the work from. In this situation remembering others haven’t done the same deep thinking as you is important for avoiding ambiguity.
Get the people doing the work to explain back to you their understanding of what you’re trying to achieve together. It’s likely there will be some gaps and things they haven’t got yet. The earlier you can catch this the cheaper it is to get everyone back on the same page.
