Principle 11 - Data Purposeful collection.

A given set of data should be collected once, from the source, and only if there is a business need for the data.

Note: The source is the person or reference that is able to confirm the data as fact.


Data will become more accurate if Penn collects it once, from the source and only when needed. Cost can be reduced by eliminating unnecessary or duplicate collection of data.


  • Careful planning and coordination are necessary to ensure that data is collected by those who will maintain its accuracy.
  • A database of record must be identified for data; applications should retrieve the data from that database rather than collect it again.
  • Applications should be developed which allow data entry by the source (allowing, for example, a student to change his or her address)..
  • Criteria need to be established to assist in determining which data is appropriate to collect.
