The Project Sponsor is like the General fighting against the status quo. Customer and vendor-side troops support you. They join hands to win against their common enemy – the status quo.
So, you must stay close to customer and vendor teams and strategise the battle against the Status quo. But, don’t worry, you are not the only leader. You are supported by the Commanders of each business division (Finance, Warehouse). You also have Commanders on the vendor side providing expert knowledge and support.
The role of the Project Sponsor is quite straightforward. Now think and act like a General to fight the battle against the status quo!
Good luck!
