2. A Take-Action Approach to Enterprise Architecture was developed and deployed at the BLM that can be effectively adapted for the Department. BLM Enterprise Architecture - Target Application Architecture (TAA) Transition Plan Assessment Actions (Enhancements,Efficiencies, Strategies) Vision Current Architecture Target Architecture 3. How was the approach Take-Action?
4. Take-Action Approach to Enterprise Architecture Four Phases 1. Establish Conceptual Vision of Target Architecture 2. Determine Scope of Assessment and Collect Data 3. Assess Alignment With FEA and DOI Architectures 4. Develop Tactical and Strategic Modernization Blueprints Department Enterprise Architecture Repository (DEAR) The Department Enterprise Architecture Repository (or DEAR) will be the system of record for critical EA information. Modernization blueprints a related set of tactical and strategic modernization recommendations. 5. 1. Establish Conceptual Vision of Target Architecture - Process Sample Conceptual Target Application Architecture FEA-PMO Guidance Technical Standards Industry Best Practices Document Target Architecture DEAR 6. 1. Establish Conceptual Vision of Target Architecture - Criteria Business Assessment CriteriaData Assessment CriteriaTechnology Assessment CriteriaService Assessment CriteriaThe criteria is derived from the target state and is used to assess how well a system aligns with the target state. Target Architecture DEAR 7. Initial efforts are focused on the 1,000 foot and the 10,000 foot levels for sets of related systems, then moved to the 30,000 foot level and higher for larger groupings of systems.

Determine Scope of Assessment and Collect Data Field Data Collection Templates are used to collect the systems data These data collection templates: 1) standardize the data collected about systems, and2) ensure uniform modeling of the systems across system groupings.

The modeling of DOI enterprise architecture 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 queries and analyses support the assessment process Systems are assessed against established criteria and are then classified DEAR 11. Our analysis template is reuseable and ensures uniform analysis across system groupings The System Grouping Analysis Template Analysis and Assessment Introduction Worksheet Provides background, takes user throughassessment step by step with automated links torelated information at summary and detailed levels DEAR 12. Well-defined criteria for assessing alignment Templates for uniform system scoring Visualization of assessment results The System Grouping Analysis Template Criteria, Scoring Against Criteria, and Visualization of System Scoring Results 13. 4.
