Procedures and instructions can have a critical role to play for some tasks in some circumstances, but we do not seem to be very good at making sure they perform their main role, which is supporting competent people.
Whilst there is a lot of guidance about writing procedures, it tends to be focussed on format only with little about the content. I have generated a checklist that aims to assess the more important issues. Also, I have created a simple template to give some ideas of how procedures can be written. The key message is that the way the procedure is described is the most important factor, keeping it as simple as possible.
