Memo Motion Study
Memo-motion or time-lapse studies is a method of working study for longer continuous work processes with the help of an appropriate camera. The method was developed in 1946 by Marvin E. Mundel at Purdue University . Initially, the need to save film material for a study for Life magazine about the preparation of various dishes in a kitchen was the motive for this approach. Once started, Mundel systematically developed it further.
Mundel published the method together with the rest of the repertoire of scientific management in his textbook Systematic Motion and time study in 1947 . Another systematic study on the possibilities of memo-motion showed advantages over the other common methods for time studies in the following situations :
- Repetitive individual work,
- Area studies, i.e. studies on a work or machine area,
- Group work studies,
- Distribution time recordings as well
- Work dimensioning.
As a very versatile method of working study, the memo-motion study gained some importance in the USA. In England, and especially on the European continent and the other industrialized countries, the reception was muted. Apparently there was first great difficulty in getting suitable cameras at all, then there was resistance to filming in general. Nowadays, the memo motion could experience a comeback, because on the one hand more and more jobs are being created for which the method is suitable and on the other hand most modern cameras are suitable for them.
