The framework is made up of 15 quality dimensions, grouped into four quality categories – Intrinsic, Representational, Contextual,  and  Accessibility. 

Subsequent research on this framework has found that it works very well in identifying and solving information quality issues and that its underlying methodology (information categories and dimensions) is robust and applicable to real-life situations.

Applying Wang & Strong’s information quality categories and dimensions to document quality, we get the following definitions:

Intrinsic DQ (IDQ)

The information in the documentation must have quality in its own right. This category is made up of the following dimensions:

• • Accurate: The information in the documentation is correct, reliable, and certified free of error.
  • Believable: The information in the documentation is true, real, and credible.
  • Objective: The information in the documentation is unbiased (unprejudiced) and impartial.
  • Reputable: The information in the documentation is trusted or highly regarded in terms of its source or content.

Representational DQ (RDQ)

The information in the documentation must be well represented. This category is made up of the following dimensions:

• • Concise: The information in the documentation is compactly represented without being overwhelming (that is, complete and to the point).
  • Consistent: The information in the documentation is always presented in the same format and is compatible with previous data.
  • Easy to understand: The information in the documentation is clear, without ambiguity, and easily comprehended.
  • Interpretable: The information in the documentation is in an appropriate language and units, and the definitions are clear.

Contextual DQ (CDQ)

The information in the documentation must be considered within the context of the task at hand. This category is made up of the following dimensions:

• • The appropriate amount: The quantity or volume of the available information in the documentation is appropriate.
  • Complete: The information in the documentation is of sufficient breadth, depth, and scope for the task at hand.
  • Relevant: The information in the documentation is applicable and helpful for the task at hand.
  • Timely: The age of the information in the documentation is appropriate for the task at hand.
  • Valuable: The information in the documentation is beneficial and provides advantages from its use.

Accessibility DQ (ADQ)

The information in the documentation must be easy to retrieve. This category is made up of the following dimensions:

• • Accessible: The information in the documentation is available or easily and quickly retrievable.
  • Secure: Access to the information in the documentation can be restricted, and hence, kept secure.
