I'm writing a new policy on the use of our document management system and I'm having a bit of a hard time arranging it. Some sections are quite short and others are fairly lengthy with a lot of subsections. The problem I'm having is whether I should just simply label them in sections like 1, 2, 3, and so on or whether I should get into organizing it into subsections like 3.1.a, 3.1.b, etc.
Does anyone know if there's a guideline on how to set documents of this nature up?
