The document discusses the need for systems to be designed to enable change. It notes that many aspects of a system can change, including code, configuration, data, models and more. The presenter advocates designing systems with change in mind using a change-oriented architecture. Specifically, the document recommends externalizing data and policies from code, creating reusable services, and using a business rules management system to help govern and implement changes in a controlled manner. It acknowledges that no single technology can address all change-related challenges but that a BRMS can assist with many aspects of managing changes.
