To spread agile approaches across an enterprise, companies either can scale lean-agile practices vertically within a business unit or horizontally across business units. Vertical scaling within a business unit calls for adopting lean and agile practices using proven frameworks. Scaling methods such as the Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Disciplined Agile Delivery (DaD) are all well-established examples of frameworks that companies can follow to promote and propagate lean-agile practices and methods. For example, a retailer could first adopt agile for its portfolio of merchandising products in a particular value stream (the steps required to make goods for available for sale, and then sell them). Next, it would adopt agile methods and practices for supply chain products related to the same value stream.
