3.3.3.2.1 Problem Description

 
The following chart represents the workloads that were
defined to the model:
 
 
      WORKLOAD            PERFORMANCE GROUPS AND/OR PERIODS
====================    =====================================
 1 - Period 1 TSO       Performance Group 2 Period 1
 2 - Period 2 TSO       Performance Group 2 Period 2
 3 - Period 3 TSO       Performance Group 2 Period 3
 4 - Period 4 TSO       Performance Group 2 Period 4
 5 - Period 5 TSO       Performance Group 2 Period 5
 6 - Development TSO    Performance Group 7
 7 - JES                Performance Group 62
 8 - Overhead           All Other Performance Groups
 
Although the analytic model was validated for the period
selected, there are still two other questions that must be
answered:
 
o  Is the selected day representative of the same time
   periods on other days?
 
o  How can the workload transaction arrival rates be expected
   to grow in the future?
 
A resource element file was used to collect 12 weeks of data
from ZONE 1 (Monday through Friday prime shift) for the
workload.  You can compare these values to the transaction
counts reported for the modeled interval to see if the
modeled interval is similar to the historical data. (Later in
this document, we show how you can use the workload
forecasting program to estimate the future values of the
workload transaction arrival rates.)
