A study of the activities of 27 machine operators during their
eight-hours shifts has been conducted, and proportions of time spend in the
following categories:
rll{
A: high-quality production,
B: low-quality production,
C: machine setting,
D: machine repair,

Of particular interest are any insights which such data might give of relationships
between productive and nonproductive parts of such shifts. All compositions sum up
one except for rounding error.References
