This document discusses improving quality when partnering with customers. It describes a case study where phase 1 of a project went poorly, experiencing delays, cost overruns, and defects due to incomplete requirements and lack of transparency. Phase 2 applied lessons learned with improved requirements gathering, testing processes, and communication. These changes strengthened the partnership and led to on-time delivery with few defects. The key is being open about challenges, willing to modify processes, understanding the client's metrics and culture, and having oversight to avoid getting lost in details.
