How to Run the Agent Development Lifecycle (ADLC) in Production

Shipping an AI agent is easy. Keeping it reliable after launch is hard. The ADLC walks you through Intent, Build, Evaluate, Deploy, Observe, then back around.

Trajectory Eval: Catch Agent Bugs Output Scoring Misses

Final-output scoring misses 20-40% of agent regressions. Trajectory evaluation scores every step an agent takes -- tool calls, reasoning decisions, order of operations -- and catches the bugs that output-only evals can't see.

Your Agent Has Observability. It Doesn't Have Measurement.

89% of AI teams added observability. 52% added evals. But only 31% can say whether their agent is getting better or worse. Here's the difference between watching your agent and actually measuring it.

AI Agent KPIs: What to Measure Before You Ship

Only 31% of teams have a measurement framework for their AI agents. Here's how to define task completion rate, escalation rate, cost per outcome, and CSAT delta before your first production interaction.

How to Eval Agents When There's No Right Answer

Most eval methods assume you know the correct response. CX agents rarely have one. Here's how to score agent quality with criteria-based rubrics and LLM-as-judge, no labeled ground truth required.

Stop Using SWE-Bench to Pick Your CX Model

SWE-Bench scores 85% or 23% depending on the harness, and neither measures customer experience. Why tau-bench, tau2-bench, and pass^k matter for CX agents.

Every Conversation Is an Experiment You Didn't Run

Your agent already ran the A/B test you're scoping. Here's how to read the results in your logs with propensity matching, synthetic control, and diff-in-diff.

Is AI Better Than Your Humans? Score Both on One Rubric

Most teams can't say whether AI beats humans because they score them differently. One rubric, run on both, sliced by segment, gives you an honest answer.

How Much Testing Is Enough for Your AI Agent?

Code coverage doesn't apply to AI agents. Here's a framework for thinking about evaluation coverage: how many scenarios you need, what distribution to target, and how to know when you've tested enough.

Is monitoring your AI agent actually enough?

Research shows 83% of agent teams track capability metrics but only 30% evaluate real outcomes. Here's how to close the gap with multi-turn scenario testing.

Your Agent Completed the Task. It Also Forgot 87% of What It Knew.

Task completion hides a silent failure: agents forget 87% of stored knowledge under complexity. New research reveals why standard evals miss this entirely.

74% of Production Agents Still Rely on Human Evaluation

A survey of 306 practitioners reveals most production agents are far simpler than expected. The eval gap isn't a tooling problem. It's a trust problem.
