Human Factors

Operational targets are defined in advance Procedures establish acceptable bounds Compliance is measured against specification Deviation is recorded and retained Inputs are screened for irregularity Outputs are sampled for consistency Variance is tracked over time Trend lines remain stable The model reflects expected use Training reduces unpredictable range Interfaces constrain available options Redundancy compensates for lapse Mitigation is pre-allocated Thresholds are calibrated to tolerance Escalation paths are documented Recovery intervals are specified Adjustment is incremental Observed behaviour aligns with projection Drift remains within margin The model reflects expected use Error is treated as patterned response Pattern is incorporated into revision Revision updates the baseline The baseline defines performance Capacity accounts for fluctuation Fluctuation informs allocation Allocation redistributes exposure Exposure remains acceptable No element operates in isolation Interaction is assumed in design The model reflects expected use The user operates within constraint Constraint defines available action Action conforms to environment Environment is constructed Tolerance includes behavioural range Range includes foreseeable lapse Lapse is factored into capacity Capacity is built accordingly All variables are integrated System conditions are satisfied The model reflects expected use
