Purpose, Process, and Monitoring Framework (PPM)


In February of 2022, the National Fair Housing Alliance (NFHA) released a new structure for auditing algorithmic systems called Purpose Process and Monitoring (PPM) that captures the life cycle of a model — pre-development, development, and post-development, including monitoring. This framework provides an approach for evaluating internal controls and mitigating risks that may be inherent in algorithmic systems and harm consumers.

A Framework for Ensuring AI Fairness

PPM Framework

The PPM framework enables:

  • Regulators
  • Businesses
  • Researchers
  • Civil Rights Groups

To conduct a critical analysis of an algorithmic system to identify its assumptions and limitations and produce appropriate recommendations to mitigate consumer fairness and privacy risks.

Virtual Briefing: “A New Algorithm Auditing Approach: The PPM Framework”

On Tuesday, March 22, 2022, the authors of the new PPM (Purpose, Process, and Monitoring) auditing framework along with leaders in algorithmic fairness hosted a Virtual Briefing on the National Fair Housing Alliance’s (NFHA’s) new PPM framework. This virtual briefing provided an overview of each stage of the PPM Framework, along with sections on the “Basics of AI and Machine Learning,” “The Landscape of AI Auditing,” and “AI Auditing as a Requirement for Fair Housing” to ensure the PPM framework is accessible and understandable to all.
