The Enterprise AI Buyer's Guide
A practical guide to choosing what to build, what to buy, who to trust, what AI implementation should cost, and what production readiness actually requires.
Executive summary
What executives should know before funding enterprise AI
- 01
Start with the business workflow, not the model.
Define the outcome, process and measurable success condition before selecting technology.
- 02
Integration complexity often drives cost more than model selection.
Enterprise data, identity, APIs, security and workflow integration usually determine the real implementation effort.
- 03
Production readiness requires more than a successful pilot.
Evaluation, observability, security, governance, failure handling and operational ownership must be designed from the start.
- 04
Choose a partner based on what they have actually shipped.
Evaluate the real delivery team, engineering depth, production evidence, governance capability and handover approach.
Decision framework · 05 decisions
Start with the five decisions enterprise AI buyers need to make
What should we actually implement?
Separate business value from AI experimentation. Define the workflow, outcome and measurable success condition before selecting a model or vendor.
Read: AI implementation servicesShould we build, buy or use a hybrid?
Buy commodity capabilities. Build where proprietary data, differentiated workflows, integration depth or control matter.
Read: build vs. buy AIWhat should implementation cost?
Cost is driven primarily by data access, integration surface, security and compliance requirements and production scope — not by model tokens alone.
Read: AI implementation costHow do we choose an AI implementation partner?
Evaluate production evidence, the seniority of the actual delivery team, engineering depth, governance and security capability, and handover.
Read: how to choose an AI implementation partnerWhat does production readiness require?
Architecture, data access, identity, integrations, evaluation, observability, security, governance, failure handling and operational ownership.
Read: what production-ready AI requiresSourcing decision
Build where differentiation matters. Buy where capability is already commoditized.
The decision is not primarily about cost. Buy where the capability is commodity, the vendor market is mature and the workflow can adapt to the product. Build where proprietary data, a differentiated workflow, integration depth or control over the roadmap decide the outcome. Most enterprises land on a hybrid, and the useful discipline is keeping the seam replaceable so either side of the decision can change later without a rewrite.
Buy
Best when
- Capability is mature
- Workflow can adapt to software
- Differentiation is low
- Implementation speed matters most
Build
Best when
- Proprietary data matters
- Workflow is strategically differentiated
- Deep integration is required
- Control and ownership are important
Hybrid
Best when
- Commodity capabilities can be purchased
- Differentiated workflows require custom engineering
- Enterprise control must be retained around the core system
Implementation economics
Integration complexity usually drives cost more than model selection
Proof of Value
- — Typically 4–8 weeks
- — Fixed scope
- — One prioritized use case
- — Real enterprise data where appropriate
- — A working system
- — Evaluation and security review
Production Implementation
- — Deeper integrations
- — Production security
- — Observability
- — Reliability
- — Governance
- — Operational handover
Cost depends far more on data access, the integration surface and compliance scope than on which model you select. Two engagements using the same model can have materially different implementation costs because their data, integration and compliance environments are different.
Primary cost drivers
- 01Data access and quality
- 02Number of enterprise integrations
- 03Security and identity requirements
- 04Regulatory and compliance requirements
- 05Evaluation complexity
- 06Production reliability requirements
- 07User and workflow complexity
- 08Operating model and handover

Partner evaluation
Evaluate the delivery team, not just the pitch
Production evidence
What has the firm actually shipped?
Engineering depth
Can they handle data, APIs, RAG, agents, integration and production reliability?
Security and governance
How are identity, sensitive data, evaluation and auditability handled?
Delivery team seniority
Who actually architects and builds the system?
Ownership and handover
Who owns the code, architecture and resulting IP?
Operating model
What happens after the system reaches production?
Ask to see the system, not just the slide deck.

What to ask before signing an AI engagement
- 01What measurable business outcome defines success?
- 02What will be working at the end of the first phase?
- 03Who will actually be on the delivery team?
- 04Which enterprise systems and data sources need integration?
- 05How will model quality be evaluated?
- 06How will security, identity and sensitive data be handled?
- 07What happens when the model or workflow fails?
- 08How will the system be monitored after deployment?
- 09Who owns the code, architecture and resulting IP?
- 10What does handover to the internal team look like?
AI partner models compared
Provider types are not ranked — each fits a different mandate.
Large strategy / transformation consultancy
Best suited to broad organizational transformation, stakeholder alignment, enterprise change programs and multi-workstream initiatives.
Global systems integrator
Best suited to large platform programs, complex enterprise estates and significant implementation capacity requirements.
Specialist AI engineering firm
Best suited to organizations that need senior practitioners to design, build and ship a focused production system alongside internal engineering teams.
Production readiness
Production AI is a system, not a model.
- 01Business outcome
- 02Enterprise data
- 03Model / Agent
- 04Enterprise integrations
- 05Identity + permissions
- 06Evaluation
- 07Security + governance
- 08Observability
- 09Production operations
The model is only one component. Production AI depends on the system engineered around it.
Where to start
Enterprise AI Proof of Value
