10.3.1.5 Data Reference Model
The DRM is a framework to promote the common identification, sharing, and use
of data across the enterprise. DRM provides for the standardization of data struc-
ture, categorization, and exchange.
Structure
promotes a common format to data
from its basic representation (e.g., ASCII) to the bundling of data elements. A com-
mon data structure is necessary if some parts of the enterprise are to find, receive,
and use the data from other parts of the enterprise. Data
categorization
describes
the general business purpose for the data, or the business context. Data
exchange
describes the bundling or packaging of data for transfer between business units or
business nodes. Effective data exchange depends on structure and categorization.

Alignment with FEA RMs
Effective alignment of IA
2
with FEA integrates risk management into the FEA
artifacts. The use of IA
2
will provide you with raw data for a risk management nar-
rative. In brief, IA
2
provides a framework that includes six IA
2
views and nine IA
core principles; this alone provides a matrix of 54 distinct perspectives from which
to identify and manage risk. The Organizational Context Framework (OCF) pro-
vides six organizational layers, each with a distinct interest in IA. The ELCM has
ten phases, each with distinct activity to support the life cycle of the capability,
service, or product. The IA
2
LoS provides 12 steps from business requirements to
O&M. A matrix of IA
2
views and OCF offers 36 distinct content perspectives. A
matrix of IA
2
views and ELCM offers 60 granular perspectives on IA throughout
the life cycle. Appendix B
provides templates for these and other matrices that will
support the integration of IA into enterprise architecture.
Which matrices apply? That is up to you. Ask yourself what the problem at hand
requires. Because this is a chapter on enterprise architecture, the applicable ELCM
phase is likely to be
architect
. he IA
2
views and IA core principle matrix apply
throughout IA integration to EA. The IA
2
LoS steps are likely business require-
ments, IA architecture, and CONOPS. Use the appropriate matrices to prompt
questions and record answers regarding risk and how to address that risk for each
element in the FEA reference models.

Alignment with PRM
PRM attempts to measure business value; integration of IA captures how to mea-
sure the business value of IA in terms of business risk management.
The process of developing a PRM includes decomposing the [enterprise | busi-
ness unit | program | project | solution | system] into FEA measurement areas,
categories, groupings, and measurement indicators. These are the
success measures
that indicate the solution is performing to expectations. With regard to IA, ask the
following questions:
