  7. 7. The Response The Enterprise Architecture (EA) A logical plan of activities and projects that guide s the progression of an organization's information systems and infrastructure from its current state to a desired future state
  8. 8. Why an Enterprise Architecture? <ul><li>Cohesion and harmony </li></ul><ul><ul><li>Avoids “silo” thinking </li></ul></ul><ul><li>Discipline and accountability </li></ul><ul><ul><li>Supportable, informed decisions </li></ul></ul><ul><li>Cheaper in the long run </li></ul><ul><ul><li>Avoids costly “cul-de-sac” directions </li></ul></ul><ul><ul><li>Increases integration </li></ul></ul>

  18. 18. EAP Essentials
  19. 19. A Myth <ul><li>You can create a detailed enterprise architecture using a single, large collective effort </li></ul><ul><li>Not true! </li></ul><ul><ul><li>There is no one “answer” </li></ul></ul><ul><ul><li>The process is evolutionary </li></ul></ul>
  20. 20. A Better Way <ul><li>Define a goal based on business priorities </li></ul><ul><li>Define a series of steps to get there </li></ul><ul><li>Deliver quick wins early </li></ul><ul><li>Review often and iterate </li></ul><ul><ul><li>Goals change over time </li></ul></ul><ul><ul><li>The process is a dynamic, moving window </li></ul></ul>

  23. 23. Key Elements…2 <ul><li>Actionable </li></ul><ul><ul><li>Interim releases can be implemented while advancing the architecture to the overall desired future state </li></ul></ul><ul><ul><li>Provides opportunity for feedback and course correction </li></ul></ul><ul><li>Prioritized </li></ul><ul><ul><li>Focus effort in areas that provide the most value to the business </li></ul></ul><ul><ul><li>Maintain support to critical business processes </li></ul></ul>
  24. 24. Versioned Releases <ul><li>Keep versions tightly focused </li></ul><ul><li>A version may address just one part of the architecture </li></ul><ul><li>“ Get it out there, get it validated, don’t make it up!” </li></ul><ul><li>Remember: </li></ul><ul><ul><li>Smaller is better than larger </li></ul></ul><ul><ul><li>Understood is better than unknown </li></ul></ul><ul><ul><li>Progress is better than promises </li></ul></ul>
  25. 25. Tie Projects to the Architecture <ul><li>Develop an architecture framework </li></ul><ul><li>Concentrate on critical areas and core processes </li></ul><ul><li>Define projects with clear, measurable goals tied to the framework </li></ul><ul><li>Execute projects & measure success </li></ul><ul><li>Plan while building; build while planning </li></ul>
  26. 26. Managed Action <ul><li>An enterprise architecture must produce </li></ul><ul><ul><li>a clear vision </li></ul></ul><ul><ul><li>actionable deliverables in versioned releases </li></ul></ul><ul><li>Don’t expect to have all the answers </li></ul><ul><li>Concentrate on small, achievable goals </li></ul><ul><ul><li>but goals that are part of a larger vision </li></ul></ul><ul><li>Don’t lose sight of the vision! </li></ul>
  27. 27. Possible EAP Pitfalls &quot;Would you tell me, please, which way I ought to go from here?&quot; ask ed Alice. &quot;That depends a good deal on where you want to get to,&quot; said the Cheshire Cat. &quot;I don't much care where,&quot; said Alice. &quot;Then, it doesn't matter which way you go,&quot; said the Cat.
  28. 28. Red Flags <ul><li>Not tied to business objectives </li></ul><ul><ul><li>approach lacks relevance </li></ul></ul><ul><li>Lack of clear direction & goals </li></ul><ul><ul><li>rudderless </li></ul></ul><ul><li>No focus on implementation </li></ul><ul><ul><li>results take too long </li></ul></ul><ul><li>No course correction </li></ul><ul><ul><li>results don’t meet needs </li></ul></ul><ul><li>Too big & complex </li></ul><ul><ul><li>risky, costly, unwieldy </li></ul></ul><ul><li>Stand-alone solutions </li></ul><ul><ul><li>perpetuate “silos” </li></ul></ul>
