5.6.3 JES Spool


Profile and Trending Analysis was used to estimate three
future monthly observations of the print load for the JES
work stations introduced in Section 3.3.3.3.  The long-term
rate of change is used to develop these estimates.  Figure
5-12 shows the control parameters used to define the study
and Figure 5-13 provides the Historical Observations, Growth
Rate, and Future Estimates Reports.

This case study shows how significantly the final monthly,
weekly or daily value may influence growth rate estimates. As
shown in Figure 5-13, the final monthly observations for all
of the remote stations are significantly lower in September
than in any previous month.  This resulted in calculations of
significant negative long- and short-term growth rates for
each of these remotes.
