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.
