Use when comparing very differently-titled roles for compensation banding, leveling, or organizational design — score each role's inherent Know-How (knowledge, skills, experience required), Problem Solving (complexity and freedom of thinking, scored as a percentage of Know-How), and Accountability (freedom to act and magnitude of impact), because job titles and informal seniority perceptions vary inconsistently across departments and don't provide a comparable basis on their own.
Use when many people request your scarce time, mentorship, or expertise and you cannot evaluate their genuine commitment level from a conversation alone — require a specific, costly, objectively verifiable unit of self-directed output (a set number of completed attempts) before engaging, because genuine commitment is what a conversation cannot reliably reveal but a completed, verifiable body of work can.
Use when deciding how to allocate a manager's or leader's limited time across competing activities — before defaulting to whatever is most urgent, estimate each candidate activity's leverage (how many people's output it affects, for how long, and whether it requires your specific position), because a manager's actual output is the output of the organization under their influence, not their own individual task completion.

Measure LCP, CLS, and INP on real user data, then trace each metric to its root cause using DevTools before optimizing.
Adopted by: Google uses Core Web Vitals as a ranking signal in Google Search (confirmed May 2021); Chrome, Edge, and Firefox report CWV metrics; Cloudflare, Vercel, and Netlify expose CWV dashboards in their analytics products
Impact: Google's CrUX data shows pages passing all Core Web Vitals thresholds have 24% fewer abandonment events; BBC found a 10% improvement in LCP correlated with a 1% increase in additional page views
Why best: Core Web Vitals measure what users experience, not what the server reports. A fast server response with a slow LCP means users still perceive the page as slow. Lab measurements (Lighthouse) show potential; field measurements (CrUX, RUM) show reality. Always diagnose with field data first.
fetchpriority="high", no preload)LCP diagnosis: LCP element is a hero image. Waterfall shows it is discovered late (not in HTML, injected by JS). Fix: move image to HTML <img> with fetchpriority="high". LCP drops from 4.2s to 1.8s.
