Best Demonstrated Practice(BDP)

 This post introduces a conceptual model for identifying and scaling best demonstrated practices(BDP) within an organization. By analyzing distribution differences between practices, the framework reveals which methods consistently outperform others. The model supports strategic decision-making by guiding expansion actions that spread effective approaches across teams and systems. Each entity is defined to support clarity, comparability, and practical implementation.

Entity Name	Description
Practice	A defined method or approach used within an organization or system.
Best Demonstrated Practice	A proven and exemplary method that consistently delivers superior results and serves as a benchmark for others.
Other Practice	Alternative methods that may vary in effectiveness or applicability depending on context.
Distribution Difference Analysis	The process of comparing practices to identify meaningful variation in outcomes, quality, or applicability.
Expansion Action	A strategic initiative to scale and disseminate best practices across the organization or system.

By formalizing the evaluation of practices through distribution difference analysis, this model empowers organizations to recognize excellence and replicate it systematically. Best demonstrated practices are not just isolated successes—they become scalable assets when paired with thoughtful expansion strategies.
