We're doing Agile development, and even though we are not going as strict as Scrum, we'd like to keep the sprint planning meeting so that the customer is able to prioritize on business values for each iteration and possibly some feedback.
That being said, having a product owner as the customer's proxy isn't really an option because the team is not big enough to separate roles like that.
At first glance I thought about talking the customer into assigning someone from his company on his behalf who'd act as his proxy, with enough power/permissions to make decitions and prioritize business values, so that we can go with the sprint planning meetings.
The customer's company isn't that big, I'd estimate a maximum of 15 - 20 employees.
Is there a better way to handle this, maybe a different perspective? How should I approach the customer and talk him into a solution?
