5. The conclusion from HF
􀀴 Super-human or common-human?
􀂃 30 years ago, this traditional perception has begun
to change:
􀀹 “ Human Errors” can not be eradicated;
􀀹 It must be expected; productive systems need to be “error
tolerance”.
􀀹 They must not rely upon 100% human performance;
develop Automation with man centered.
􀀹 We must build a “safety net” or a system

􀂾 5th percentile female to the 95th percentile male
􀂃 Design for the average
􀂾 A checkout counter
􀂃 Imperfect correlations between body dimensions
