Target State ArchitectureTSA Presented by Dawn Michels Enterprise Information Architect Andersen Corporation Feb 15, 2006 For Dama Minnesota
What is a TSA? • A TSA (Target State Architecture) is a tool or method for the IT and Business functions of a company to work in concert to insure that business needs are addressed using the capabilities of IT most effectively. • In addition it is written in terms that resonates with the business and is validated and approved by key stakeholders of both parts of the organization.
Our approach was to… • Assess • Understand and assess key business strategies and business unit plans • Evaluate current business models, high level-gaps between business process and technology offerings • Identify IT organizational implications • Organize • Develop principles and values • Develop specific list of architectures • Document • Identify specific opportunities & pain points • Document current and target states of specific architectures • Prioritize • Prioritize business needs/intersection with IT capabilities • List specific initiatives that would move us in the right direction
Who Participated • Executive Leadership • Business Management • Sr. IT Management • Enterprise Architects • Business/IT Liaisons
Assess • The Enterprise architecture team reviewed business strategies and work plans after they were crafted by the business units • Next they identified what technical capabilities were required to support these strategies • Gathered the known supporting applications • Identified where IT organizational implications might be experienced
Organize • A core team of Architects and Sr. Management (both business and IT) developed a core list of principles and value statements between both organizations • Gathered list of known supporting applications • Identified where IT organizational implications might be experienced do to potential change
Document • Created a list of business, information, solution and technical architectures • Documented pain points, opportunities and current business activities • Created graphical representations where appropriate – illustrating current state • Validated with key business liaisons • Identifying scope of effort • Resources & costs estimates • Iterative steps / roadmap to achieve Target State
Prioritize • Provided an overall synopsis to business of requirements as well as sampling of TSA’s • Asked business to prioritize which capabilities were most important to them, and which would coincide best with expected work activities this year • Applied these needs to our own resource and staff planning • Reviewed with business and secured support from them as well as shared resources.

Prioritize and define transition state Identify Current State Assess what the business needs Identify Target State So what is in a TSA Document? • Objectives • Opportunities • Gaps • Key Issues & Performance – Current State • Key Requirements – Target State • 3-5 Year Recommendation – Transition State
Keep it simple – 1-2 pages each Opportunities Objectives GAPS Current State (Picture if Possible) Target State Transition Process
Time for a break • Come back for a live example
<< Business or I.T. Name of Process > Target State Architecture
Outline • Name of Process Architecture Objectives • Name of Process Architecture Opportunities • Name of Process Architecture Gaps • Key Issues & Performance – Current State • Key Requirements – Name of Process Target • 3-Year Recommendation – Transition State
Name of Process TSA Objectives • Bullet 1 • The bullets on this page are to emphasize the business or technology challenges you are trying to impact • Bullet 2 • Should be specific, in business terms and measurable • Bullet 3
Name of Process Architecture Opportunities • The items on this slide should be specific projects / Initiatives coming up that would afford a change to your environment • Bullet 2 • Bullet 3 • etc
Key Issues & Performance current state • List of specific current business pains and performance
Key Requirements (Specific examples of requirements) target state Ex: • Reduce number of originating sources • Define information authority / stewardship • Cease proliferation of new data streams • Explore methods to support corporate Information library.
