Skipping governance and evaluation design for regulated or high-stakes use cases
Without explicit safety, policy, and evaluation controls, conversational behavior can become harder to manage once deployed. Deloitte, Capgemini, and IBM Consulting deliver governance and monitoring practices designed to control conversational risk and quality drift.
Launching without a plan for knowledge grounding and ongoing knowledge lifecycle updates
Conversation accuracy depends on disciplined knowledge grounding and data readiness, which can degrade when content is not curated and updated. Infosys and NTT DATA emphasize operational monitoring and knowledge lifecycle support, while Deloitte pairs retrieval-focused approaches with evaluation and monitoring practices.
Expecting lightweight timelines for complex integrations and cross-stakeholder alignment
Heavy enterprise integration and governance requirements extend delivery cycles because orchestration, change management, and evaluation need stakeholder input. Globant, Accenture, Deloitte, and Capgemini all align with enterprise delivery scale, while teams trying to move too fast often encounter process-heavy scoping needs.
