Priority
Order of priority should decide for you. This needs to be assessed and ordered with regard to the elements crucial to your business, starting at the entry point; at the top. Anything else that is not mentioned as a Critical Function moves to the bottom. Do add notes or instructions for each functionality and references to your Standard Operating Procedures (SOP) manual; who to refer to when something goes wrong. Make sure you test these elements regularly.

By maintaining an order of priority your staff can act independently to address the component problems associated with your business functionality. This is an advantage, as it will save managers time and leave staff with a reference point that they can always turn to.
