What is the best way to get a C$-$suite sponsor if one is not readily available?

There is no need to get a C$-$suite sponsor; lean six sigma is easy enough to do with just middle managers.

Go to social media and pressure your CEO into sponsoring your initiative.

Invite shareholders to put pressure on the C$-$suite to support your initiative.

Run a great pilot project to give you the story and the numbers to sell lean six sigma.
