  • A short example of work  The following slides show some of the work I have done in the IT area around IT processes and Enterprise Architecture.  This shows some high-level models and is not meant to be a complete picture. Just examples of ideas. 9/2/2013 2
  • Two Views of Enterprise Architecture  Business View (using BIZBOK)  Business Strategy Mapping  Capability Mapping  Organizational Mapping  Value Mapping  Information Maps  Initiative Mapping  Product Mapping  Stakeholder Mapping  A Business Architecture from the business view  Managed by the business  IT View (using TOGAF)  Business Architecture  Application Architecture  Information Architecture  Technology Architecture  A “big picture” view of the IT landscape  Managed by IT 9/2/2013 3
  • Business View  Should a company start an EA program from a business perspective or an IT perspective?  If the IT department has mature processes, especially the Architecture processes, then go to the business.  If the IT department does not have mature processes, then start in IT  “let’s get our own house in order first” – CIO of a client 9/2/2013 4
  • IT Solution Process Model  The end-to-end IT Solution Process can be divided up into five (5) sub- processes:  Demand Capture  Capture demand from all sources  Demand Classification  Classify demand which determines the path to take  Solution Strategy  Define the strategy, do the architecture work  Based on classification, may require a large amount of work (e.g. Strategic Initiative) or may require little to no work (e.g. change request for a report)  Solution Delivery  The PMO/SDLC processes which engages the various COEs and SMEs as necessary  Solution Support  Support the implemented solution, create new demand (fixes, updates, improvements, etc.), retire obsolete solutions Solution Process Demand Management Demand Classification Solution Strategy Solution Delivery Solution Support 9/2/2013 5
  • IT Processes and Lead Roles The 5 basic IT Processes The Lead Roles  Planning  Architecture  Project management  System development  Operations support  Planning Committee  Enterprise Architect  Project Manager  Solution Architect  Operations Manager 9/2/2013 6
  • Example Unified IT Process Model  Clearly defined, technology-enabled, end-to-end unified process and lead roles 9/2/2013 7
  • SOA Processes and Lead Roles The 5 basic SOA Processes The Lead Roles  Planning  Architecture  Project management  Services development  Operations support  Services Analyst  Services Architect  Project Manager  Services Developer  Services Administrator The SOA (or shared services) model is a microcosm of IT 9/2/2013 8

  • Another view  EA and SOA work across the enterprise. SA works siloed within the tactical projects. SOA = Services Oriented Architecture SA = Solution Architecture PMO = Project Management Office 9/2/2013 10
  • Demand Classification exampleComplexity Factor Low=1 Medium=3 High=5 NOTES Enter Score 1 Project Type UPGRADE Involves a change in capacity of existing technology or service. Usually additional capacity or additional locations. NEW ADDITION Involves the addition of a new technology or service with no replacement of existing technology or service. REPLACEMENT Involves the replacement of old technology or service with a new technology or service. Degree of difficulty influenced by new technology and whether it replaces older technology or is simply added to the environment.2 Technology Established company standard A standard in the industry, but new to company. A new technology, not necessarily a standard, no internal expertise. Open standards should be encouraged. 3 Scope Involves only one location and one function Involves only one region and up to four functions Involves all regions (locations) and cross- functional The wider the geographic scope the more complex the project.4 End User Impact Completely transparent to end users Minimal amount of communicaiton necessary to inform end users of planned changes. No training required Changes require frequent communication and some degree of end user training 5 Implementation Technique Can be implemented without disturbing existing service, users can migrate to new environment New technology/service is installed in parallel and users are migrated in segments "Flash cut" requires new technology/service to replace old with no overlap 6 Capital Required (Life Cycle) Relatively small capital (<$50K) Medium capital required ($50K-$2.5M) Large capital required (>$2.5M) 7 Operating Costs (Annual) Small operating costs (<$100K/year) Medium operating costs ($101K-$999K/year) Large operating costs (>$1.0M/year) Includes depreciation, equipment lease, 8 Vendor Relationship No new vendors involved, upgrade using existing vendor product No new vendor involved, using a new product from existing vendor New vendor with no prior business relationship Established vendors are (genarally) easier to do business with 9 Resource Requirements Can be completed with use of only internal resources (and industry partners) Requires minimal resource dependency outside company Requires significant resource requirement from outside company and/or vendor 10 Project Duration < 3 months 3-12 months > 12 months 11 Other Legal requirements and/or critical to business 9/2/2013 11
