Designing processes - EMC Community Network

Creating the Data Model
should occur. You also have to choose the activities in which to collect this data. Consider the
following when determining which SDT and package attributes to monitor:
1. If an attribute’s value does not change from one activity to another, then only monitor the attribute
once rather than for each step in the process. If you monitor this attribute in several locations,
then you are capturing meaningless rows of data that are needlessly filling up the audit trail and
BAM database.
2. Do not collect process data unless you absolutely must and if you need process data only once, you
may want to collect it at the end of the process.
3. If attribute values change during a process and you want to monitor this change, then select to
monitor the attributes within the activities that generate the change. However, reports that rely on
business data aggregation may be inaccurate. For example, if the order is entered for three widgets
in Activity A but is later changed to nine widgets in Activity B, then the correct number is nine.
But if you record both numbers, then you will compute six as an average value, which is incorrect.
