Keep it simple, lay out the tasks, group them together, set the delivery dates.
Don’t give into the chaos of everything being everywhere all the time.
Don’t give into the chaos that others have and worry about what could, might, or should be.
Work the problem, and deliver the problem, one task at a time.
Your job might not have originally been part of bringing them online and refocusing the team, but now it is. You can either join the fray or the lead.
