I manage a team who develop a Web-based CRM. We are trying to introduce a UX Designer to this project, but I don't know the best approach to do that. I have two proposals, and I'm leaning more towards the 2nd one.
In the first approach we have two product backlogs; the UX team will build all the mockups, studies and docs and deliver to the Dev Backlog. Only stories already mocked-up would be 'developable'. Then the product owner would prioritize the 1st and the 2nd backlogs. Not always the first task delivered by the 1st team would be developed first by the 2nd team.
We had only one backlog and the UX designer would be part of team, I think this approach it's more 'lean' and brings the UX to the vision of the sprint, he becomes more engaged to the goal. But... would create a little waterfall by sprint, where the developers would need to wait him decides the best visual approach would be used to the new feature.
What strategy do you think it's better? Do you have another proposal?
