Quality of Information

Quality of Information

1. 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.

2. 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     • Outdated info can lead to things like bills being sent to the wrong address.

3. 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.

4. 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.

5. 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.

6. 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.

7. ACCURACY

   • Correct, truthful and has no errors
     • The wrong postcode would prevent the delivery of items
