Common mistakes when buying generative ai consulting
A frequent mistake is selecting a provider based on governance rhetoric without matching governance artifacts to how engineers will ship and operate the system. KPMG and Accenture both tie governance to evaluation and rollout workflows, while other providers can shift depth toward partner platform buildout.
Another mistake is assuming tool calling and orchestration can be handled as an afterthought once the model is integrated. Tata Consultancy Services emphasizes controlled execution paths, and Boston Consulting Group defines evaluation gates and risk controls across the lifecycle, which prevents later rewrites when production constraints surface.
Choosing a governance-led engagement without specifying how approval workflows map to evaluation and rollout artifacts
Demand control mapping deliverables like KPMG provides so approval workflows connect to model evaluation and operational rollout artifacts. If the plan stays at an executive level like McKinsey & Company’s adoption operating model, specify who implements the rollout artifacts.
Treating tool calling as integration work that can be completed after production governance is finalized
Tata Consultancy Services ties tool calling and orchestration to controlled execution paths, so it is safer for enterprises with internal service dependencies. Accenture builds guardrails around prompt evaluation, red teaming, and human-in-the-loop review, which reduces the risk of uncontrolled execution.
Underestimating the client-side data and governance engagement needed for production RAG
EPAM Systems requires disciplined data and governance engagement for production rollouts and can increase client-side workload for evaluation and acceptance criteria. Capgemini can feel heavy for small teams without platform support, especially when RAG and ingestion work needs detailed client-owned data pipeline work.
Assuming an engagement focused on program governance includes developer-first API automation depth
Boston Consulting Group can package documentation artifacts for program governance that may be program-oriented rather than developer-first APIs. Validate automation and API surface expectations against provider delivery depth using demonstrations tied to tool calling buildouts.
