Scaling Agile has been the topic of conversation for years, has been achieved for years as well yet rarely documented and socialized. In 2009, while leading an Agile transformation in the parent company at the same time standing up new Scrum teams in their startup subsidiary Ben realized that Scrum should or at least would in his case be the foundational framework for scaling Agile.
Keeping it simple with a collection of small, manageable, functional teams vertically sliced into portfolios, programs and projects to help mitigate the risk of loosing site of the goals and/or objectives of the organization while keeping true to the Agile principals Ben will show you how he and his team scaled Agile multiple times throughout multiple enterprise international organizations, using Scrum as the foundational framework complimented with Lean, Deming, XP and Kanban.
Something important to know is you must use TDD and/or BDD with a continuous integration environment as well as feature/code prefixes and vertical slicing.
