Measure this by extracting a sample of data from a source data store,
mapping its meaning to a downstream target data store that the data has
been propagated to or has been created independently, to compare if they
match. To do this, you must know the object that the attributes describe,
and the semantic meaning of the data values. You map that to the target
data store and compare or translate to evaluate if the data is semantically
equivalent.
This can be tested with electronic tests if you are able to map cleanly
the semantics of the data in the two data stores. For example, Gender
code of M = Male and F = Female maps to data store 2 as 1 = Male and
2 = Female.
Step P2.3: Identify Information Value Circle
This process identifies all Activities of the life cycle from the originating cre-
ate process to delivery to all Information Consumers, both internally and
externally.
Objective of Step P2.3
To determine all business processes and applications, and all Information Producer
roles that create or update information along with process interdependencies,
processes that retrieve and present the Information, and Knowledge Worker
(Information Consumer) roles that apply it. This is to identify points where
defects may be introduced and where data Equivalence must be controlled. It also
identifies where process failure will o
