Understand How it Works
George Smith, Manager, United States, Member
You should understand that D0, D1 and D2 all work together
The idea is that D0 has some information of the problem, basic information customer, parts defect codes and other information especially the emergency response action (era).
D1 starts the team, get at least a champion or 1 or 2 members.
As the problem definition gets traction in D2 and more detail and interim containment, the make up of the team will change in which case you can just circle back and update the team list.
The team make up and roles are continuously monitored to make sure the correct people are part of the problem solving team as the details and can emerge.
Remember this is not really a serial process
, it is a parallel/serial process.
