Mis 004

  1. 1. IT Architecture
  2. 2. The IT Architecture <ul><li>To manage valuable resources like information effectively and strategically, the IT provides tools to the organisation which assist in : </li></ul><ul><ul><li>@ Capturing @ Processing @ Communicating </li></ul></ul><ul><li>data throughout the organization and between organization and its external environment. </li></ul><ul><li>“ IT not only helps business run more effectively, but it can actually change the way the business is done.” - Seger and Stoddard, HBS, 1993. </li></ul>
  3. 3. The IT Architecture <ul><li>IT architecture for a company defines the company’s IT infrastructure and includes policies and guidelines that govern arrangements of IT resources. </li></ul><ul><li>IT architecture also provides a framework to facilitate decisions regarding technology investments and use. </li></ul><ul><li>The logical and coherent IT plan ensure more strategic technology decisions. Thinking about architecture is thinking about building an IT infrastructure. </li></ul>
  4. 4. CREATING AN IT ARCHITECTURE <ul><li>The business executives start with a vision of doing business and articulate their related IT requirements to their information managers (IT Architects). </li></ul><ul><li>IT architects assemble various parts which meet the needs of business strategies. </li></ul><ul><li>IT business architect may make suggestions of new technology capabilities which are available and could be used. </li></ul><ul><li>Lack of top management involvement and guidance might hinder harnessing of IT potential. </li></ul><ul><li>To use IT effectively and to build effective IT architecture, an understanding of effective integration of IT into the vision of organization’s competitive strategies is a must. </li></ul>
  5. 5. WHY AN IT ARCHITECTURE <ul><li>As a blue print for providing a conceptual framework in: </li></ul><ul><li>Building </li></ul><ul><li>Using </li></ul><ul><li>Communicating </li></ul><ul><li>Maintenance </li></ul>
  6. 6. COMPONENTS OF IT ARCHITECTURE <ul><li>IT architecture can be defined into 3 distinctive layers: </li></ul><ul><li>Inventory of IT “Building Block” </li></ul><ul><li>Functional use of IT </li></ul><ul><li>The strategic plan for use of IT </li></ul>
  7. 7. IT ARCHITECTURE Hardware Inventory Software Inventory Data Inventory Commn. Inventory Baseline Applications Blueprint Baseline Data Blueprint Baseline Commns. Blueprint Planned Applications Blueprint Planned Data Blueprint Planned Commns. Blueprint COMPUTER ARCHITECTURE STRATEGIC PLAN COMPANY BUSINESS STRATEGY Functional Use of IT Building Blocks for IT Architecture
  8. 8. IT INVENTORY <ul><li>The basic building blocks of IT architecture are : </li></ul><ul><ul><li>Computer hardware </li></ul></ul><ul><ul><li>Computer software </li></ul></ul><ul><ul><li>Data </li></ul></ul><ul><ul><li>Communication links </li></ul></ul><ul><li>This layer presents the hard technology with which the general managers are generally not involved </li></ul><ul><li>The basic familiarity with computer system, however, critical if the general managers to be involved in the development of IT architecture </li></ul>
  9. 9. FUNCTIONAL USE OF IT <ul><li>IT inventory tells What technology components and capabilities exist where as functional use of IT tells How these capabilities are employed with in the organization. This layer is a blueprint for building IT architecture. </li></ul><ul><ul><li>- A baseline blueprint is an assessment of IT component and function. </li></ul></ul><ul><ul><li>- A planned blueprint is a prescription of future IT investments and design. </li></ul></ul><ul><li>At this conceptual level of IT function, the IT architects and IT users come together. They both discuss : </li></ul><ul><ul><li>The application that will be available </li></ul></ul><ul><ul><li>The data that will be accessible </li></ul></ul><ul><ul><li>Data communication that will be possible </li></ul></ul>
  10. 10. FUNCTIONAL USE OF IT <ul><li>Whereas the IT users articulate the desired function of the system, IT Architects prescribe an appropriate technology. </li></ul><ul><li>They build functional IT architecture. The functional use of IT will have 3 components: </li></ul><ul><ul><ul><li>-- Applications </li></ul></ul></ul><ul><ul><ul><li>-- Data </li></ul></ul></ul><ul><ul><ul><li>-- Communication </li></ul></ul></ul>
  11. 11. STRATEGIC PLAN FOR IT <ul><li>Today the user managers can no longer afford to depend upon the - So called computer gurus for creating a vision for IT use. </li></ul><ul><li>Because IT represents significant expenditure and offers unprecedented opportunity for gaining competitive advantages. </li></ul><ul><li>The best way to blend the two is “meet-in-the-middle-approach” to IT architecture planning. </li></ul><ul><li>Where as the business vision flows in the top-down direction, technical expertise might flow in the bottom-up direction. </li></ul><ul><li>Participating from both the ends of organization is crucial to build and manage an effective IT Architecture. </li></ul>
  12. 12. DEVELOPING AN ARCHITECTURE <ul><li>- It is an ongoing activity </li></ul><ul><li>- Hard choices </li></ul><ul><ul><ul><li>Company-wide vs. local applications </li></ul></ul></ul><ul><ul><ul><li>Standards </li></ul></ul></ul><ul><ul><ul><li>Vendors </li></ul></ul></ul><ul><ul><ul><li>Rules </li></ul></ul></ul>
  13. 13. STEPS <ul><li>Articulate business strategies and implications for IT architecture </li></ul><ul><ul><li>Shared vision of the company’s overall business strategy and its functional IT requirements </li></ul></ul><ul><li>Baseline blueprint of the company architecture </li></ul><ul><ul><li>A complete description of the current IT structure </li></ul></ul><ul><li>Determine the key architecture questions </li></ul><ul><ul><li>What we have, what we need, what is available and should we invest </li></ul></ul><ul><li>Design a planned architecture blueprint </li></ul><ul><ul><li>What the architecture would be </li></ul></ul><ul><li>Initiate the architecture plan </li></ul><ul><ul><li>- Incremental/quantum (investments) </li></ul></ul><ul><ul><li>- Evolutionary/revolutionary (replace or surround the old with new) </li></ul></ul>
