When you choose to take a workshop-based co-creation approach, a good first step is the "Initiate" workshop:

Step 1: Download the agenda for running your initating session (incl. PPT)

Step 2: Prepare for the workshop working with the the goals section and the limits section of the organizational structure kit, including three tools to

• Develop principles (Tool 1)
• Derive implications of your strategy (Tool 2)
• Define scope and boundaries of your org design work (Tool 3)

Step 3: For overall project planning, check out the process guide for running organization projects.
