A manual production line was examined for effects of 2 different mater
ial flow policies and 3 different goal-setting policies. The line used
a push system, where workers work at their own pace(assuming availabl
e work) and pass work to the next station as soon as the work is compl
eted, and a pull system, where workers pass work only when the next wo
rker needs it. Three different goal-setting policies involved no speci
fied goals, individual goals, or group goals confounded with monetary
incentives and feedback. Measurements were taken from unobtrusive vide
otaping and worker questionnaires. Analyses indicated productivity inc
reased approximately 25% when group goals were matched to a pull polic
y (compared to a push policy with no specified goals). Other results r
elating to productivity and job satisfaction are discussed.
