Zusammenfassung der Ressource
Quality of Information
- RELEVANT
- Information needs to be related to its
intended use.
- Asking for yearly sales and getting
monthly sales: cannot pinpoint
which month was most profitable
and why.
- UP-TO-DATE
- Information that has been obtained
recently is most up-to-date.
- Outdated info can lead to things like bills being sent to the wrong address.
- COMPLETE
- Data must not have any gaps and
should cover everything needed.
- Promising items delivered next day, while not
knowing the item is out of stock.
- CORRECTLY TARGETED
- Information needs to be targeted at the person who is going
to use it.
- Don't ask a vegetarian about their meat eating habits, or a motorbike driver
about car driving.
- UNDERSTANDABLE
- The meaning of any information
should be clear to the user and any
codes should be explained.
- Complex data in tables should be
converted into graphs or charts.
- HAS USER CONFIDENCE
- The user must not have any doubt in the system they use.
- The system may tell them there are more of a
product in stock than there actually is. This
causes the user to doubt the system in the
future.
- ACCURACY
- Correct, truthful and has no errors
- The wrong postcode would prevent the delivery of items
