Core element of the REFA Methodenlehre is the process orientated Labour Organization.

Expirations of enterprise are measured, analyzed, evaluated thereby and improved afterwards. The entire enterprise forms a unit, which must itself become conscious individual employees its role in the Produktionsablauf.

Also the work ergonomics plays an important role.

Time and motion study

A goal of this REFA method is the determination of standard times for processing steps, in order to reduce Ineffizienzen in such a way in the production process. For a certain processing step by stop watch the actually needed actual work time is determined concretely and the actual performance degree is judged at the same time the processing step accomplishing worker. The standard time results now from the multiplication from actual work time and actual performance-degree-lies the actual performance degree of the worker for example straight at 100%, then the standard time corresponds to the actual work time. If the actual performance degree is below 100%, then the standard time is smaller than actualwork time beside the traditional time and motion study gives it multi-moment studies, as well as systems pre-determined times (e.g. see MTM).

Further REFA methods are seized e.g. .die work-sampling, with this procedure by coincidence observations and fixed round course plans by the manufacturing all resulting activities and by means of statistic evaluation for example the allowance percentages be determined could. Depending upon required accuracy, a multi-moment study can be very lengthily, in individual cases is then a "Verteilzeitaufnahme" to be preferred.
