The Build Standard

Six pillars that define how we build AI-powered products — effective, reliable, secure, and designed to improve over time.

Not every AI product needs to be perfect on day one. But every product benefits from asking the right questions early. The Build Standard defines what "good" looks like — so teams can make informed tradeoffs instead of discovering problems in production.

Pillar 1

Product Clarity

Every AI product must solve a real, validated problem with a tightly defined scope and measurable success criteria.

Key questions

? Is this solving a problem someone actually has — or a problem we assume they have?
? Can we describe the first useful version in one sentence?
? What does success look like in numbers, not opinions?
? What is explicitly out of scope for version one?

Best practices

Validate the problem with real users before writing code.
Define success criteria that are measurable and time-bound.
Scope the first version to the smallest thing that delivers value.
Document what the product does not do — scope boundaries prevent drift.
Map the user journey before the system architecture.

Pillar 2

AI Effectiveness

AI should meaningfully improve the outcome. If a simpler solution works, use that instead.

Key questions

? Is AI actually improving the outcome, or adding complexity for its own sake?
? How do we measure whether the AI component is working well?
? What happens when the model gets it wrong?
? Could a rule-based system achieve 80% of the value at 20% of the cost?

Best practices

Choose models based on task fit, not hype — smaller models often outperform larger ones for focused tasks.
Build evaluation harnesses that measure accuracy, relevance, and failure rates on representative inputs.
Design graceful degradation — the product should remain useful when AI confidence is low.
Use human-in-the-loop patterns for high-stakes decisions.
Separate AI behavior from business logic so each can be improved independently.

Pillar 3

Reliability & Trust

Users must be able to depend on the system in production. Consistency and predictability matter more than peak performance.

Key questions

? Can users predict what the system will do in a given situation?
? How quickly do we know when something is broken?
? What is our recovery path when the AI produces bad output?
? Are we monitoring the right signals — not just uptime, but output quality?

Best practices

Monitor AI output quality continuously, not just system health.
Build circuit breakers that fall back to safe defaults when quality degrades.
Log inputs, outputs, and decisions for debugging and improvement.
Set latency budgets — users notice when AI makes things slower.
Test with adversarial and edge-case inputs, not just happy paths.

Pillar 4

Security & Data Governance

Data must be handled responsibly. AI systems introduce new attack surfaces and privacy considerations that require deliberate design.

Key questions

? What data does the AI system have access to, and is that the minimum necessary?
? How do we prevent sensitive information from leaking through model outputs?
? Who can see what the system produces, and is that appropriate?
? Are we compliant with relevant data handling requirements?

Best practices

Apply least-privilege access to all data the AI system touches.
Implement input and output guardrails to prevent prompt injection and data exfiltration.
Minimize PII in training data, prompts, and logs.
Maintain audit trails for AI decisions that affect users or business outcomes.
Separate customer data boundaries — no cross-tenant leakage in multi-tenant systems.

Pillar 5

Operational Excellence

The system must be maintainable, debuggable, and cost-efficient over time — not just at launch.

Key questions

? Can someone who didn't build this system debug it at 2am?
? Do we know what this system costs to run, and is that sustainable?
? Can we deploy changes safely and roll them back quickly?
? Are decisions documented so future teams understand why things work this way?

Best practices

Automate deployments with rollback capability.
Track AI costs per feature, per user, per request — not just in aggregate.
Implement smart cost controls: caching, model routing, token budgets.
Write runbooks for common failure modes.
Maintain a decision log that captures why architectural choices were made.

Pillar 6

Adaptability

AI capabilities change rapidly. Systems must be designed to absorb improvements without full rebuilds.

Key questions

? Can we swap the underlying model without rewriting the product?
? How do we evaluate whether a new model or technique is actually better for our use case?
? Are prompts and AI configuration managed separately from application code?
? Can we A/B test AI behavior changes safely?

Best practices

Build model-agnostic abstractions — never hard-code to a single provider.
Separate prompts, system instructions, and AI config from application logic.
Maintain evaluation datasets that let you benchmark new models against current performance.
Use feature flags to roll out AI behavior changes incrementally.
Design for the capability curve — build systems that get better as the underlying AI improves.
