Using Blueprint for Established Application

Hi, we (my client and team) are looking for some examples and deep dive into how existing clients with established case types, tasks, etc are using 
Blueprint. Blueprint today? 
We understand the net new implementation use case but are in need of examples how it applies to adding on to existing work done. 

Thanks!

@kuchj1 - We employed the below approach it worked out for us.
