This has existed for a lot longer than computers.
Relevance - the data being used must apply directly to the
decision being made
Timely - data must be efficient and must be provided in a timely
manner
Thorough - the data must be complete
Characteristics of Quality Data
Accurate - data should be captured only once, where possible
and should be captured as close to the point of activity as
possible.
Reliable - data should reflect stable and consistent data
