You can either Start a Checklist now - or Schedule it to be Started for you later.
Work comes from all kinds of situations. The triggers are either reactive or proactive.
1. Reactive: We are responding to a situation due to circumstance or event.
In this case we pull the process to us.
This is when we Start a Checklist.
2. Proactive: We have planned a course of action or a discipline we set in advance.
In this case we push the process to us.
This is when we Schedule a Checklist.
