pg 151, Babok v3, The structure of the business analysis information is also an information
architecture. This type of architecture is defined as part of the task Plan Business
Analysis Information Management (p. 42). The information architecture is a
component of the requirements architecture because it describes how all of the
business analysis information for a change relates. It defines relationships for
types of information such as requirements, designs, types of models, and
elicitation results. Understanding this type of information structure helps to
ensure that the full set of requirements is complete by verifying the relationships
are complete. It is useful to start defining this architecture before setting up
infrastructure such as requirements life cycle management tools, architecture
management software, or document repositories.
