Operating at the Edge of the Envelope
summary
A near‑miss on a glacial rappel illustrates how human teams operate at the edge of the envelope: surprise is normal, failures cluster at shifting boundaries and near‑misses erode the margin of manoeuvre until something breaks. Uses Rasmussen’s model to map cost/schedule pressures against a line of technical failure, draws on 30+ years of cognitive systems engineering, embedded SRE fieldwork (summer placements) and a consortium (including Salesforce and New Relic) producing qualitative reports on rebound, robustness, graceful extensibility and sustained adaptability.
