A naive reorganization of people from monolithic, role-based, large teams into small, multidisciplinary teams aligned to value streams without attention to how the technical architecture landscape will also evolve will lead to suboptimal improvements at best. At worst, the reorganization adds another layer of coordination and dependency management. The new teams could be working with an application architecture in which features require changes across a number of components and demand coordination with other value streams, slowing lead time and reducing flow efficiency.
