Information is always available to and usable by the individuals, groups or processes that need to use it.

If data is not easily accessible users may decide to make their own copies. This is a security risk, as the more copies of data there are, the harder the data is to protect.

Organisations should have a culture of checking and reporting when data is an accurate. EG. A teacher contacting a parent to find that the telephone number is out of use, should inform the schools data manager.

Organisations should have a planned pattern of data maintenance where they check the data. Possibly by sending a contact their information and asking them to confirm if it is correct.

Inaccurate data can lead to conclusions based on false information or time being wasted and phone calls to numbers that no longer exist.
