Business is just a collection of processes.
The first step in creating a business process is gaining clarity of what the outcomes of the processes are.
The outcomes don’t change. You may change how you create the outcomes, or who will create the outcomes. Having clarity in the outcomes results from having clarity of your business as a whole.
Having clarity in the outcomes allows you to choose if you want to create those outcomes or whether you want to have someone else create them. Clarity is the first step in designing a business.
