Before going live, top teams run the AI system in parallel with existing workflows, processing real production traffic without exposing the output. This "shadow mode" provides an honest accuracy benchmark on unfiltered data and is treated as a non-negotiable step to de-risk the launch.

Unlike traditional software where problems are solved by debugging code, improving AI systems is an organic process. Getting from an 80% effective prototype to a 99% production-ready system requires a new development loop focused on collecting user feedback and signals to retrain the model.

To ensure AI reliability, Salesforce builds environments that mimic enterprise CRM workflows, not game worlds. They use synthetic data and introduce corner cases like background noise, accents, or conflicting user requests to find and fix agent failure points before deployment, closing the "reality gap."

Teams often mistakenly debate between using offline evals or online production monitoring. This is a false choice. Evals are crucial for testing against known failure modes before deployment. Production monitoring is essential for discovering new, unexpected failure patterns from real user interactions. Both are required for a robust feedback loop.

Treating AI evaluation like a final exam is a mistake. For critical enterprise systems, evaluations should be embedded at every step of an agent's workflow (e.g., after planning, before action). This is akin to unit testing in classic software development and is essential for building trustworthy, production-ready agents.

The non-deterministic nature of agentic AI makes traditional pass/fail testing insufficient. Businesses must adopt a multi-dimensional scorecard for every interaction, evaluating metrics like compliance, factual accuracy, latency, and intent recognition, not just task completion.

To make its AI agents robust enough for production, Sierra runs thousands of simulated conversations before every release. These "AI testing AI" scenarios model everything from angry customers to background noise and different languages, allowing flaws to be found internally before customers experience them.

Treating AI evaluation as a single, pre-launch check is a mistake. Model behavior drifts due to fine-tuning, infrastructure changes, and shifts in user queries. Production AI systems demand a continuous evaluation pipeline integrated into the deployment lifecycle to catch regressions and ensure ongoing reliability.

To get the best results from an AI agent, provide it with a mechanism to verify its own output. For coding, this means letting it run tests or see a rendered webpage. This feedback loop is crucial, like allowing a painter to see their canvas instead of working blindfolded.
