Hard to give you an answer case by case.
Mainly, just keep in mind a few milestones,
• Be sure that the tension is grounded in day to day activity of the organization
• Try to express the tension trough this user story format:
"As <role>, I want <goal/desire> so that <benefit>."
• Ask for a tension driven starting proposal, even weird
• Rely in the governance process as a "grinder"
Perhaps could you attend to the next coach office hours session.
Hope that helps.
