Assessment is needed for construction. The better the assessment the better the construction. This also means assessment of Human performance and potential errors in new systems. |
|
Assessing work-places is comparably easy. Often simple rearrangements make products easier to handle. Simple methods and low effort may already lead to enhanced products. |

For quantitative assessment, we need models to classify the observations or to develop a predictive method. Models and classifications can be simple or complex. We use models and classifications in any second of our life - for walking and eating as well as as for flying to the moon. |

A golden ergonomic law: Strive for compatibility. However,do not make compatible what has to be distingished by a user. Sometimes controls have to be made incompatible in order to reduce Human errors. |

Assessing individuals is not useful for system-design. Abstraction is necessary in order to keep predictions valid enough for the user group of a system. Abstraction needs valid data and well constructed scales. |
|
Assessment of hazards is challenging but essential for health and safety. Human Reliability Assessment methods were developed for that. Have a look at the CAHR method and links to find out more. |
||
Assessment usually comprises the average performance of user-groups. Incidents show that individuals and individual decisions are not well reflected in old assessment methods. New assessment methods therefore take the context of human actions into account. |
|
That's what we want: an efficient and never failing system. The interaction of equipment and humans is often not treated well enough. The connectionism assessment is overcoming this deficiency and achieving high reliability. |
