Core insight: not all signals are equal—your agent's performance and ROI hinge on allocating a deliberate signal budget that balances marginal value, cost, and operational friction. This briefing gives executives a tight framework: (1) measure marginal value of incremental signals, (2) classify signal costs across acquisition, labeling, latency, and governance, and (3) select operational levers (instrumentation, sampling, synthetic features) that maximize decision value per dollar. You'll get a three-step 90-day mini-audit to set or reset a signal budget, a short worked example (lead qualification agent), and clear acceptance criteria to know when to invest more signal vs. stop. Designed for leaders deciding where to direct scarce data, engineering, and attention resources so agentic projects scale with predictable value instead of noise.
