How is the approach Take-Action?

• Evaluate systems for
• Which systems are old and/or costly to maintain?
• Develop recommendations on how to move forward
  are rectify
• Opportunities to tie systems together more
  effectively.
• Identify systems that need to talk but dont
• Identify business process issues that are not
  currently addressed.
• Opportunities to centralize information assets.
• Improve reporting, security and data integrity.
• Evaluate systems capabilities for supporting
  strategic goals and objectives
• Evaluate against end and intermediate strategic
  outcomes and measures
• Deliver short and longer-term recommendations
  that can be acted upon
• Which systems would need to be consolidated.
• Which systems would benefit from shared
  application services.
• Potential investment proposals that may need to
  be considered now.
• Comprehensive views of how the IT systems support
  the lines of business.

Take-Action Approach to Enterprise Architecture
Four Phases
1. Establish Methodology for Defining
Modernization Blueprint.
Modernization blueprints a related set of
tactical and strategic modernization
recommendations.
2. Determine Scope of Assessment and Collect Data
4. Develop Tactical and Strategic Modernization
Blueprints
Department Enterprise Architecture Repository (DEA
R)
3. Assess Alignment With FEA and DOI Architectures
The Department Enterprise Architecture Repository
(or DEAR) will be the system of record for
critical EA information.

2. Determine Scope of Assessment and Collect Data
Field Data Collection Templates are used to
collect the systems data
System Architecture Template
These data collection templates 1) standardize
the data collected about systems, and 2) ensure
uniform modeling of the systems across system
groupings.

3. Assess Alignment with FEA and DOI
Architectures - Process
Systems are assessed against established criteria
and are then classified
Extent to which the system complies with
current Security requirements and extent of
progress through the CA process.

Data Architecture

• Degree of architectural compliance with the
  Target Architecture.
• Extent to which system design requirements are
  defined and documented
• Extent to which systems interfaces are defined
  and documented
• Extent to which high-level design or operational
  concepts are defined.

• Systems capability for supporting associated
  Strategic goals and objectives as defined in DOI
  Strategic Plan.
• Extent of stakeholders feedback for accomplishing
  performance measures associated with strategic
  goals, objectives and performance measures.
• Lack of functional overlap with other systems as
  defined by DOI BRM.
• System incorporates re-engineered/streamlined
  business processes (workflow) in an automated
  fashion that supporting DOI Strategic goals and
  objectives.

• Existence and documentation of data standards
  and Protocols
• Relative maturity and accessibility of system's
  data storage and access methods
• Relative overlap with data stored in other
  Interior systems .

• Extent of maximum use of shared, existing
  infrastructure components and services
• Extent of compliance with Technology Reference
  Model standards, protocols and best practices.

elements and their relationship to assessment
criteria facilitates line of sight analyses.
Popkin SA is used to model the relationship
between inputs, outputs, and outcomes. Model

Assessment Quadrants
Migration (Integrate) Systems with relatively
high business fit and relatively low technology
fit where it is cost effective to upgrade the
technology architecture/infrastructure to adhere
to the TRM and conceptual TAA.
Target Systems with relatively high business
and technology fit.
Legacy - Systems still required by DOI that
should be considered for integration with other
systems or consolidation with target systems.
The systems being consolidated will essentially
be retired. These systems have relatively low
business (e.g., alignment with DOI Strategic
plan, CRV, CAP, process and data maturity) and/or
technology fit (e.g., alignment with TRM,
Conceptual TAA, etc.)
Migration (Consolidate/Retire) Systems with
relatively high technology fit however, the
business fit is relatively low. These systems
should be examined for possible retirement and/or
consolidation of required functionality and data
into Target Systems.

4. Develop Tactical and Strategic Modernization
Blueprints
Modernization blueprints (tactical and strategic
modernization recommendations) are produced and
should be managed in parallel.

Conclusion

• Structured Enterprise Architecture Process
• Phase 1 Establish vision
• Phase 2 Critical to limit scope and constrain
  data collection
• Phase 3 Assess to develop relative scores
  against Target
• Phase 4 Develop recommendations that can be
  implemented now and in a coordinated fashion to
  address the future
• Addresses Enterprise Architecture both from a
  top-down strategic approach and a bottom-up
  tactical approach
• Strategic approach makes mission alignment IT
  recommendations
• Tactical approach makes systems improvement
  recommendations that move systems incrementally
  toward target architecture and can be implemented
  with operations and maintenance budget dollars
• Business owners prioritize recommendations for
  implementation consistent with project management
  governance processes
• Recommend this process be used to develop
  modernization blueprints across the DOI
