1. Before we start: What is a process? Let's get back to basics by defining processes first. A process is a series of actions or steps repeated in a progression from a defined or recognized 'start' to a defined or recognized 'finish'. The purpose of a process is to establish and maintain a commonly understood flow that allows a task to be completed efficiently and consistently.
