This was tested in 2018 when Rocket Mortgage used a Scaled Agile model to organize 2,000 of their 26,000 team members into teams, and the teams into collections of "release trains" centered around business value streams. The Client Marketing Release Train then took the Scaled Agile model that all release trains were implementing and layered Scaled Scrum with Dev.Ops practices on top of it. By doing so, they reduced the average feature cycle time from 83.7 days to 11.6 days and increased feature delivery by 721% with higher quality. Here we describe the tools and techniques they used to deliver more than twice the value at half the cost.10 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalAgile and Lean: Organizations, Products and Developmentleanperformancesafescrumscrum@scaletext10.24251/HICSS.2022.881
