2 Project Strategy Meeting 22 nd April 2008 Enterprise Architecture International Dr Christopher J Harding Senior VP, Sales

3 Situation We have been engaged by TB Fabrications Ltd to develop an Enterprise Architecture Vision based on SOA We hope that this will lead to a full architecture development contract We will use TOGAF The Vision that we produce will be as described in TOGAF Phase A It will be presented to TB s Board and Architecture Team 22 April,

4 Objectives Scope the work required to develop Vision and Full architecture By taking a first pass through phases B, C, D. 22 April,

5 Agenda Background Inputs from TBFL Our SOA Artefacts Baseline and Target Architectures Business Information Systems Technology Conclusions 22 April,

6 Background 22 April,

7 TB Fabrications Family-owned firm Makes custom metal fabrications for the construction industry (staircases, balustrades, guttering, doors,..) Factory and offices in Glasgow, UK $50M turnover, 250 employees Business suffering due to poor enterprise architecture 22 April,

8 Phase A: Architecture Vision Objectives: To ensure proper recognition and endorsement from business sponsors To validate the business principles, business goals, and strategic business drivers To define the scope of the current architecture effort To define the relevant stakeholders, and their concerns and objectives To define the key business requirements and the constraints To articulate an Architecture Vision addressing requirements and constraints To secure formal approval to proceed To understand the impact on, and of, other enterprise architecture development cycles To develop business case for SOA for this architecture cycle H G F A E B C D Inputs Request for Architecture Work (based on SOA concept) Business strategy, business goals, and business drivers Architecture principles, including business principles, when pre-existing The SOA Principles, SOA Reference Architecture, Guidelines, and concepts Enterprise Continuum (list of existing services and processes) Establish the project Identify business goals, drivers Define scope Define constraints Identify stakeholders Define key business requirements Prepare as-is and to-be business, functional, organization models Prepare SOA business case Develop statement of architecture work and Secure approval Outputs Approved Statement of Architecture Work with SOA as style Plan for the architectural work Refined statements of business goals and strategic drivers Architecture principles, including business principles and applicable SOA principles Key business requirements and constraints Architecture Vision, including: Current State Business model, Functional and Geographic models Target high level Service Oriented Business model, Functional and geographic models SOA driver (goal) Business case for SOA 22 April,

9 Phase A Objectives To ensure proper recognition and endorsement from business sponsors To validate the business principles, business goals, and strategic business drivers To define the scope of the current architecture effort To define the relevant stakeholders, and their concerns and objectives To define the key business requirements and the constraints To articulate an Architecture Vision addressing requirements and constraints To secure formal approval to proceed To understand the impact on, and of, other enterprise architecture development cycles To develop business case for SOA for this architecture cycle 22 April,

10 Phase A Outputs Approved Statement of Architecture Work with SOA as style Plan for the architectural work Refined statements of business goals and strategic drivers Architecture principles, including business principles and applicable SOA principles Key business requirements and constraints Architecture Vision, including: Current State Business model, Functional and Geographic models Target high level Service Oriented Business model, Functional and geographic models SOA driver (goal) Business case for SOA 22 April,

11 Phase A Steps Establish the project Identify business goals, drivers Define scope Define constraints Identify stakeholders Define key business requirements Prepare as-is and to-be business, functional, organization models Prepare SOA business case Develop statement of architecture work and Secure approval 22 April,

12 Phase A Inputs Request for Architecture Work (based on SOA concept) Business strategy, business goals, and business drivers Architecture principles, including business principles, when pre-existing The SOA Principles, SOA Reference Architecture, Guidelines, and concepts Enterprise Continuum (list of existing services and processes) 22 April,

13 Inputs from TBFL 22 April,

14 Request for Architecture Work Organization sponsors Organization's mission statement Business goals (and changes) Strategic plans of the business Time limits Changes in the business environment Organizational constraints Budget information, financial constraints External constraints, business constraints Current business system description Current architecture/it system description Description of developing organization Description of resources available to developing organization 22 April,

15 TB Fabrications Mission To produce high-quality custom-designed metal fabrications for the building industry anything made of metal that the architect wishes to specify but cannot obtain off the shelf. 22 April,

16 Business Strategy Family owned and run Design and production at single site All work in-house - no sub-contracting Sell to trade customers architects and builders Product promotion to the public as well as to trade Advertising and sales through trade publications and the Internet Materials ordered to meet demand no significant stock holding 22 April,

17 Business Goals and Drivers Long-term goal Steady profit to support owners Short-term drivers Sales have been declining steadily No major change in business environment Good product and workforce Customer dissatisfaction due to long lead times and missed delivery dates More efficient operation based on better IT is seen as solution 22 April,

18 Opportunities and Constraints Opportunities Death of founder enables radical changes to be made Recent web-based system enabling customers to design and configure products is a success attributed to SOA Constraints New development means borrowing should be phased with return from initial phases Don t want to lay off staff 22 April,

19 Scope of Eventual Architecture Work To develop an enterprise architecture for TBFL with recommendations for a phased implementation. (TOGAF Phases A-D with recommendations that could be followed in E-G) 22 April,
