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.
Is there a strategist in place?
Has the strategist recruited a PM to help?
Has the PM completed the project start procedure?
Have we had an internal kickoff?
Have we made sure the Strategist has access to the Hubspot lead for the deal?
Have we made sure the Strategist and PM have reviewed and absorbed the SOW?
Have we set up a kickoff call between the team and the client?
Are the Strategist and PM ready to brief the team and get started?
