Another common pitfall is assuming governance covers only access to the model endpoint. Accenture, Capgemini, IBM Consulting, and PwC emphasize RBAC plus audit logs tied to orchestration changes, and missing that linkage creates audit gaps during prompt and retrieval configuration updates.
Treating prompts as the only interface and skipping data-model contracts
Require schema alignment between prompts, retrieval artifacts, and downstream application inputs to prevent contract mismatch. Thoughtworks and PwC deliver schema-first structured output pipelines, while organizations relying on prompt-only interfaces often face downstream integration rework.
Evaluating governance without auditing orchestration changes
Ask whether audit logs capture changes to prompts, connectors, retrieval configuration, and workflow orchestration, not just user authentication. Capgemini ties audit log controls to LLM orchestration changes and access policies, and Accenture ties RBAC governance to audit log practices for controlled operations.
Assuming automation exists without a documented API and provisioning workflow
Require a named automation and API surface for provisioning, config, orchestration, and evaluation loops. Thoughtworks, IBM Consulting, and PwC define automation around model gateways, evaluation harnesses, and orchestration hooks, while Google Cloud Professional Services uses documented Cloud APIs for provisioning and orchestration.
Under-scoping environment separation for sandbox and production
Demand repeatable provisioning workflows and sandbox validation steps that match governance rules across environments.
