I will outline the process we went through in DES to develop and implement (from producing catalogs to writing the papers) a combined '3x2pt' analysis of weak lensing and galaxy clustering with our first year data set. The expectation of how this would happen two years ago and the reality provide a series of lessons for planning future analyses and organizing work in large collaborations. Despite challenges and complete changes in the analysis, data, and management along the way, we were able to successfully bring together the work of dozens of DES scientists to produce over 250 pages of simultaneous results split across more than a dozen papers supporting a 'key' cosmology analysis of weak lensing and large-scale structure. With other visitors from DES, we can discuss some of the ways we went about organizing and implementing this project and what lessons we have learned.
