Other questions may occur to you, and that's fine, but answering these should get you started. Reviewing these answers when you review your procedure will make sure your original assumptions are still valid. You should review your procedures annually, even semi-annually if there's lots of new technology or people being introduced. These workshops can be run in a day, and the resulting procedure can be reviewed and signed off within a week. That's not much investment necessary for a smooth operation.
Good people are good value.
A good person, skilled, experienced, full of common sense instead of foolish pride, is worth more than any technology. You can always buy technology because it lies around on shelves and in warehouses. Good people don't grow on trees, aren't manufactured, and can't be cloned in a test-tube. You can't buy good people. The smartest investment an organisation can make is to identify its good people and reward them.
