My high-level current state framework consists of Why -> Who -> How – > What
Why
Why is the current state the way it is? What are the high-level business requirements that are driving the current state?
Who
Who is involved in the current state and what roles do they play.
How
How is the current state performed? What are the processes? What are the preconditions for processes? What roles fulfill the processes? What resources are required for the processes to be carried out?
What
What is produced by the current state? What assets are created? What data is created?
Understanding the current state is the baseline for moving forward.
