Unformatted text preview: During the two week period of the third phase of the field experiment, it
was observed that this audit was completed fully every day by cell members.
The effect of management intervention can be short lived The fourth phase of the study removed the automatic continual display via the monitor in the Oil Room. It was observed during
this time frame that waste levels increased to about second phase levels. Average waste was still
about 9% lower than what was observed during the control period, but, as with the second phase of
the study, the difference was statistically insignificant from control. Although it was hypothesized
that waste levels would rise, the abruptness of the rise was nevertheless surprising given the impact
of management intervention in the previous phase of the experiment. It is unclear what happened
during this time period to the audits because field observations were unable to be made due to time
constraints. However, based on their impact during the third phase, it is likely that the audits were
