Starting off simple…. I like to build stuff, but I don’t re-invent the wheel every time I make something.

I use plans Basic design elements are here….

I will customize based on my needs ….

Turned this… Requirements: Better lighting More storage to keep desk space clear Hide router, PC and electrical cords Happy wife

….into this Process and plans utilized Cabinet building Face frames Electrical Under cabinet lights Lights in ceiling Draw construction Cabinet door …all designed and laid-out before the project was started. This is small scale architecture

Same thing applies to home designs…. What are your needs Same thing applies to home designs…. What are your needs? 1 BR, 2 BR, 5 BR?

Once you know your needs, you need to apply accepted methods for laying out electrical, plumbing ….

Questions and Perspectives that impact the Architecture of the project (Home building) What are the needs? Business requirements? How many bedrooms? Bathrooms? Garage space, Workshop space! What are the systems needed? Electrical, plumbing, framing requirements, etc What processes do are required? Building permit, contracts, etc Perspectives: Home owner Electrician Plumber Contractor Framer Zoning board

The point ….. We use skills every day that are based on what we have done before [our experience or someone else’s] No need to “re-invent the wheel” Plans that meet your requirements exist, and if not, pick and choose what you need to meet your requirements Learn to view things from the perspective of other professionals Frameworks /Models Customize and pick frameworks or process that you need Numerous levels of professionals from various silos will be involved in enterprise architecture

Enterprise Architecture What’s an Enterprise Architecture and what’s it for? EA “…is the organizing logic of business processes and IT infrastructure reflecting the integration and standardization requirements of the firms operating model” MIT Center for Information Research Alignment Flexibility Helps with strategic alignment and optimization of funds Improve the

Traditional approach to IT issues…..

Federal Enterprise Architecture Model This is very similar to the Open Enterprise Arch Model on page 124

Enterprise Architecture Cycle Document Organization Current Situation Project future state Gap analysis ID improvement projects Execute projects

The Accenture Case: What was the problem that Accenture faced? Spin off from Anderson $23B 187,00 employees, 75% mobile Needed to create a new organization out of the old Needed to replace basic IT services Needed to duplicate others Reduce IT spending $30M

The Accenture Case: What was the new leadership’s vision for IT? IT Philosophy Managed Services Approach Consolidate, Standardize and Centralize Operations Any time, Anywhere Access Strong IT Governance Governance – centralized, delegate up Manage Services – Customer driver – what do they want Consolidate – economies of scale, reduced local market power - ENTERPRISE ARCHITECTURE Any any – Leverage internet

The Accenture Case: What were some of the EA issues they faced? Varied PC and network environment Varied network platforms Many data centers Local support and applications High costs Table discussion: 10 minutes

The Accenture Case: What infrastructure EA decisions did they make? Leverage internet for remote site connectivity Combine voice and data support Create one network with common infrastructure Centralize data centers first, then virtualize servers Table discussion: 10 minutes

The Accenture Case: What was the major issue they faced with SW? Best of breed One platform What are the positives and negatives of of each approach? 15 minutes Each group take one approach BREAK OUT +’s and –’s of eachj

Breakout Groups (two groups)

The Accenture Case: How did their decisions reduce cost? Centralization provides economies of scale Standardization proves purchasing leverage Reducing complexity: Minimizes maintenance costs Makes future implementations easier Allows businesses to integrate better Outsourcing cuts cost of standard services Table discussion: 10 minutes

The Accenture Case: What were the results? -64% IT cost per employee -58% IT cost as a % of revenue -50% IT workforce as a % of total headcount

Breakout Groups (three groups)

Accenture In your breakout groups, take 20 minutes and discuss the following: From an EA perspective, what did Accenture’s current state look like in 2001/2002? What were its strengths and weaknesses? What did their desired future state look like AT THAT TIME? How did this reflect business strategy?

Accenture In your breakout groups, take 20 minutes and discuss the following: What emerged as their core IT philosophy? How did it reflect their desired future state? Where did they start? What projects came first? Why?  What application vendors did they select? Why? How did they implement?

Accenture In your breakout groups, take 20 minutes and discuss the following: How did they measure their progress? What kind of results did they receive? Where do you think they have gone since 2010? Why? What evidence of EA thinking do you see in this case?

Auditing a Company’s EA Take 15 minutes and prepare a summary of the key things you would want to look at when auditing a company’s enterprise architecture efforts? NOTE: The EA checklist on pp 153 & 154 of the text will help you get started

Breakout Groups

Auditing a Company’s EA Take 15 minutes and prepare a summary of the key things you would want to look at when auditing a company’s enterprise architecture efforts? Do they have one? If so, what framework are they using and are staff familiar with it? What key business processes and data do they highlight? Do these make sense? What is the business strategy? How deep is the understanding? Does it match what the business says its strategy is? Have they done all the work in a logical way using a tight methodology? Does their logic make sense? Is the EA being followed or is it sitting on someone’s shelf? NOTE: The EA checklist on pp 153 & 154 of the text will help you get started
