Developing your own system

To develop your own system, it should now be clear that you need to:

  1. Break everything up in to, at most, ten areas.
  2. Break those areas up in to, at most, ten categories.
  3. Assign numbers to those areas and categories.
  4. Start creating items and assigning Johnny.Decimal IDs.
  5. Track your numbers somewhere.

It’s not much more complicated than that.


Advice: don’t rush the process

I’ve done this a lot now and the best piece of advice I can give is: take your time.

When you start a new system—let’s say you start a new job—you don’t know what you don’t know. It takes time to recognise patterns and understand the scope of the task at hand.

If you rush in, you’ll create categories that are too broad or narrow. You’ll mis-categorise things. You’ll end up having to change it later, which is possible, but a pain.

Think on it for a week

I believe you should think on any new Johnny.Decimal system for at least a week.

This thing will be with you for a long time; don’t rush it.

Use sticky notes

During this week, write everything that might be a category on a sticky note. Use many sticky notes.

Move them around on the table until they naturally create their own areas.

Leave room to grow

After almost 3 years managing a complex IT project, I had used about 30 categories across 7 areas. Don’t create areas and categories for the sake of it.
