Case Study — Technology Leadership
Engineering Metrics Deep Dive
Four metrics, 22 consecutive months of exact data, one plain-language review — built for a CEO audience, not an engineering standup. Reliability, quality, throughput and cycle time, charted month by month rather than smoothed into a before/after. Hover, focus or drag any chart for the exact figure; zoom in with the strip under each one.
