It is essential for products to meet the needs of the market. At avarto Systems S4M they develop parts of it together with their clients. A year ago they took a bigger initiative involving innovative ways of cooperating: The customer owns his own backlog covering the business needs and three product owners on the product side own their respective product backlog. Based on a hierarchical alignment on strategic (quarterly), tactical (monthly) and daily alignment the client hands in his business needs and a joint team translates them on short notice to user stories and running software which is continuously deployed. 

The presentation or case study will focus on:
- set up of the organizations on the customer side and on the vendor side
- description of the overall end to end process coordinating 5 scrum teams.
- description of the process of UX design using a living style guide and multiple UX designers
- introduction of important artifacts like functional architecture, joint acceptance test cases

The speaker will share a few lessons learned on an agile cooperation model building a product albeit the client has only a limited market view. They would like to understand the experience from the audience to improve their model.
