Description
Indicators

Note 1: Following are presented the definitions found for the construct in the used references, together with the theory/model.
Note 2: The same construct can be present in more than one theory/model.
Note 3: If the construct was not proposed in the original theory/model, it is identified as "Additional to theory/model".

Definition: The desired characteristics of the information system itself which produces the information.

Theory/model: DeLone and McLean
Reference: (DeLone & McLean, 1992)

Note 1: This list contains all the indicators (measuring variables) as defined by the authors when proposing/using/applying a theory/model in a context. It also includes the scales used to measure the variables.
Note 2: Some of the indicators are context-dependent.
Note 3: The same construct can be present in more than one theory/model.
