Engineering Discipline
Does the provider treat AI as part of a broader software system with proper testing, monitoring, and deployment practices?
Business Alignment
Can the provider translate business goals into AI solutions with measurable outcomes?
Long-Term Support
AI systems evolve over time. Strong providers support monitoring, retraining, and continuous improvement.
