Illumination StudiesIllumination Studies
The The firstfirst illumination study was illumination study was made in three departmentsmade in three departments
The illumination level in each The illumination level in each department was increased at department was increased at stated intervalsstated intervals
Puzzling resultsPuzzling results– Increased production did not Increased production did not
correspond with increased lightingcorrespond with increased lighting– Reduced production did not Reduced production did not
correspond with reduced lightingcorrespond with reduced lighting

The The secondsecond illumination study illumination study utilized a test group and a control utilized a test group and a control group.group.
Illumination intensities were varied Illumination intensities were varied in the test group and compared to in the test group and compared to the control group.the control group.
Both groups showed increases in Both groups showed increases in production rates that were not only production rates that were not only substantial but also nearly identical.substantial but also nearly identical.

¨ Examined effects of group piecework pay system on productivity
¨ Workers under piecework system should produce as much as possible¨ Scientific management assumes that people are
motivated only by money
¨ Result: Production less than maximum¨ Conclusion: Social pressure caused workers to
produce at group-norm level
