Hi @Jason_JB Thanks for your questions. For this particular contest, your reasoning is correct. We are looking for integration stories across different Adobe Experience Cloud solutions, so it could be Workfront Fusion with Adobe Experience Manager, Target, Marketo Engage, etc.
I believe the customer definition in this contest is a bit broader than that. It can be anyone that uses Adobe Experience Cloud solutions in tandem with each other, so it could a system admin, practitioner, consultant, partner, or a similar role. Sharing an integration story that is primarily for an internal audience is also fine (assuming your compliance teams are open to sharing this information). In your example, you could demonstrate the efficiency improvements after optimizing your Workfront workflows for transparency.
Let me know if you have any other questions.
