Multi Moment Analysis (MMA) History
L.H.C. Tippett a British statistician is generally considered as a mental father of the multi-moment analysis. Since 1927 he was investigating in his “Snap reading method of making time studies”. He examined for example downtimes in a weaving mill with personal coincidental tours with paper and pencil and detected that a relatively small number of samples is sufficient in order to enter the actual downtimes within the organization with amazing accuracy.
C.L. Brisley discovered 1952 that multi-moment analysis are applicable not only for industrial investigations but also on the investigations of office activities.
