When the strategist is running the planning workshop, which of the following is a great practice to encourage the client to upgrade to a larger engagement package?

Bring your sales rep into each workshop for them to explain the pricing of the other service packages.
Show them which action items on the wishlist could be implemented this cycle if they were to upgrade.
Walk through what you’ve built for other clients who have already made the upgrade.
As a group, read through a number of blogs which outline new best practices your team could incorporate if the client upgrades.
