Human Factors — Why Competent People Make the Wrong Call

Topic: DP Watchkeeping · Sub-topic: Human Factors  ·  Level: DPO / Senior DPO  ·  Read time: 9 min

1. What / Why / How

A senior DPO who has run the same routine operation dozens of times without incident may skip a check that would normally warrant a look — not through carelessness, but through normalisation of deviance combined with experience bias. Repeated exposure without incident can quietly erode the standard of vigilance applied to a genuine anomaly.

2. Recognition / Risk / But

The real risk isn't a knowledge gap — it's that an experienced DPO's confidence can make a skipped check less visible and harder to challenge than an obvious gap would be. But: this pattern is genuinely difficult to self-correct by simply “deciding to be more careful,” because the erosion happens gradually, reinforced by a track record of nothing going wrong.

3. Now / What next / Decision / Why

Correcting it requires either an external prompt (a colleague, a structured habit, a deliberate routine) or genuine self-awareness. A junior colleague noticing something wasn't checked needs a working environment where raising a technical observation is expected and welcomed, regardless of relative seniority.
