High-velocity IT culture and behaviour
What this domain tests
This domain tests the behaviours that make speed sustainable: safety culture, Lean culture, quality culture and ethics, plus the leadership behaviours that reinforce them.
Core concepts
- Safety culture: people surface errors, near misses and bad news without fear of punishment, so problems are fixed before customers find them. It rests on psychological safety and is expressed through blameless post-incident reviews that ask "what in the system allowed this?" rather than "who did it?". Safety culture is not risk-blindness: accountability for actions remains, blame for honest error does not.
- Lean culture: respect for people plus continuous improvement (kaizen). Two habits matter for the exam - go and see (genchi genbutsu: decide from observed reality, not reports) and stop the line (anyone may halt a failing build or release, as on the andon cord).
- Quality culture: quality is built in, not inspected in at the end; teams do not knowingly hand off defects or technical debt without a recorded decision.
- Ethics: HVIT raises questions about data use, automated decisions and workforce impact. Ethical review belongs in the decision, not only in the legal department's retrospective.
- Leadership behaviours: make work visible, model the behaviours, and measure what reinforces them (flow, defect escape rate, time to restore) rather than only utilisation.
Worked example
A release causes a two-hour outage. A blame-oriented manager asks, "Who deployed this?" An HVIT leader runs a blameless review: the pipeline had no canary step and tests did not cover the failing path. Actions are systemic - add progressive rollout and a missing test - and the engineer who deployed becomes the person most willing to raise the next warning early.
Traps that cost marks
- Reading "safety culture" as the absence of accountability.
- Reading "Lean" as headcount reduction rather than flow and continuous improvement.
- Delegating ethics to compliance after the design decision is made.
