With SAFe, a major lean objective is to maximize customer value by achieving the shortest sustainable lead-time while maintaining the highest possible quality products and services. But to fully realize this vision, you need to leverage more than just planning in your SAFe implementation. You need to take a systems approach and optimize the flow of work across your entire value stream.
While SAFe does integrate DevOps to accelerate value delivery to the customer, it does not completely bridge DevOps and planning processes or manage inter-team dependencies. To take a systems approach to SAFe from idea to delivery, you need Value Stream Management to unify your value stream toolchains.
