The Estimates of Future Observations Report provides estimates of future observations for specified data elements. As with the Historical Observation and the Growth Rate Reports, you define the structure of this report using the Profile and Trending Analysis control screen (see Figure 5-6). Figure 5-3 shows a sample Estimates of Future Observations Report.

Figure 5-3. Estimates of Future Observations Report
The following information is shown:
SYSID: The SYSID specified by the SYSID control
parameter.
ZONE: The ZONE specified by the LVL control
parameter.
The number of estimated future observations is determined by
a control parameter you specify on the Profile and Trending
Analysis control screen. For each estimated future
observation, the following data elements appear in the report
columns:
MONTH: The MONTH and YEAR of the historical
observation. If you specify the WEEKS time-
span when the Capacity Planning database file
is created, the title of this column is WEEK
ENDING and the week ending dates appear in the
report. If you specify the DAYS timespan when
the Capacity Planning database file is created,
the title of this column is DAY ENDING and the
day ending dates appear in the report.
NOTE: If you specified DAYNAME as the secondary
summarization level then these dates will be
seven days apart. Otherwise, the Capacity
Planner will generate one observation per day.
You can specify the remaining columns of the report through
the control parameters on the Profile and Trending Analysis
control screen. For example, the first column of the report
shown in Figure 5-3 contains the following information:
CHANNEL 1 The future estimates of the average monthly
BUSY (%): values for channel 1 utilization. To calculate
these values, repetitively apply the growth
rate you specified to the final observation for
the variable. For channel 1 busy, the
estimated value of 9.0% for September 1998
corresponds to a 4.4% growth of the August 1998
value, 8.6% (taken from the historical report
shown in Figure 5-1).
These reports are intended to provide simple sense of
direction estimates for future values. These estimates are
not statistically based forecasts, but provide estimates
based on historical growth rates.
