Planning always helps. You may know what you're doing, but others may not. Tell everybody what you're going to do before you do it, to avoid wasting time. If you're not sure yet, then build a prototype to help you decide. Approach the administration framework as if it were a development task. Make a list of things you don't know yet, and work through them one by one.
This is deliberately a very short recipe. Everybody has their own way of doing things, and it's very important not to be too prescriptive about how to do things. If you already have a plan, great! If you don't, think about what you need to do, make a checklist, and then do it.
