FAQs

Focus on proven delivery, not strategy alone. Check quantified results, relevant industry experience, and technical team depth. Review commercial models for accountability.

2. What differentiates AI consulting firms from AI implementation partners?

Consulting firms focus on strategy and roadmaps, while implementation partners deliver production systems and integrations. Enterprise outcomes depend on execution depth, so firms combining both capabilities drive better results.

Typical programs run 6–24 months. Initial pilots take weeks, while full rollout requires phased deployment and integration.
