Sales Department to Production Department

In order to start the first phase of a project (whether that is UX, Visual Design, Development, etc), these are the steps that should happen between the sales department and production department.

Have we been informed who the DRI will be, and made sure they have a todo in Basecamp HQ to complete the project start procedure?
Have we had an internal kickoff with the Head of Production and DRI?
Have we made sure the DRI has access to the Hubspot lead for the deal?
Have we made sure the DRI has reviewed and absorbed the SOW?
Have we set up a kickoff call between the team and the client?
Is the DRI ready to brief the team and get started?

After the project is handed off to the DRI, the DRI should run the procedure. At that point, the project will be underway.
