We have many examples of customers taking a process-driven approach to implementation and getting huge benefits.
Here are some success stories. These are some quotes from clients from our days at Nimbus in 2001-2011. Nimbus is a business analysis / process mapping app. The examples are all in the public domain and are all systems implementation related. None are Salesforce, because back then Salesforce implementations weren’t as established or complex in the Fortune500 which was our target market.
However, our own internal implementation of Salesforce was a Salesforce Case Study. Roll the clock forward to 2016 and Salesforce implementations are as big and risky as the examples below. So now the approach is totally relevant.
