PMI-CPMAI highlights transparency and explainability as core aspects of responsible AI. Transparency requires that stakeholders can understand how and why an AI system reaches its outputs, including underlying logic, features used, limitations, and assumptions. Explainability practices include documenting model design choices, data lineage, performance metrics, and decision rules in a way that is meaningful to technical and non-technical audiences.

PMI’s guidance on responsible AI and governance stresses the need to capture and maintain thorough documentation of AI decision-making processes throughout the lifecycle. This documentation typically covers: model architecture, training data characteristics, feature importance, decision thresholds, known failure modes, conditions under which performance degrades, and interpretability artifacts (e.g., example explanations, model cards, or similar summaries). It serves as the primary mechanism for meeting transparency requirements and supporting audits, risk review, and stakeholder communication.

While data quality, ethical guidelines, and feedback mechanisms are all important, they address different aspects (reliability, values, and continuous improvement). The activity that directly ensures transparency and explainability requirements are met is documenting the decision-making process of the AI model.
