A flow process chart is used to study an operation
in detail, so each step is listed regardless of its
importance. Information on direction, distance
traveled, and method of movement may be used for
determining materials handling options. Unit times
may be useful data if individual items, such as pots
and plants for transplanting, are being processed.
Total times, such as greenhouse growing time for
different cultivars or species, may be important.
Data gathered should include labor, machine and
space use, utilities, grade factors, environment,
and any other information that will contribute to
understanding and improving the operation.
