Two programs have been developed for facilitating data collection on a portable computer. These are based on two established techniques of work study, Activity Sampling and Time Study. The integral micro-cassette drive is used to store the data in sequential files. The data are later transferred to a larger memory micro-computer for analysis. Alternatively the data may be stored on audio-cassette or transferred directly to a printer.

Analysis of the data requires the coalescence of the data collected with both the Activity Sampling and Time Study programs. It is usual to combine both these techniques on any one study. It is also possible to combine data collected, on any one site, over a period of days or even weeks. The analysis of the data falls into two distinct parts, total basic times and site factors. Basic times have been found to be constant from site to site. Site factors allow for the variation in actual times between sites, and are a measure of the motivation of the operatives and the effectiveness of the management. Both basic times and site factors are used in the determination of planning times.
