Responding to Regulations Confidently and Efficiently
Marek Matejka, Meta
Regulatory requirements, particularly those mandating user setting changes, frequently pose a significant challenge due to their volume and potential impact, if implemented incorrectly. This talk presents a tried-and-tested process and engineering framework developed at Meta to respond to these regulations both confidently and efficiently. We detail the multi-step approach, beginning with critical cross-functional (XFN) alignment to define scope and setting values. We then provide an overview of the core framework, which drastically reduces implementation time—achieving code-completeness for setting-related requirements within a single working day. Finally, we discuss the complete lifecycle, emphasizing mechanisms for a confident launch, and, crucially, ongoing compliance. We explore the use of the Swiss Cheese Model for high assurance, robust monitoring, and solutions for complex edge cases such as conflicting regulations or regulatory overlap. This framework is a blueprint for scaling effective and trustworthy regulatory responses that others can adopt and build on top of.
