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.
