Transcript of "EA Doing The Right Things Right V1 Manageware"

  1. 1. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right ® IBM Software Group Actionable Enterprise Architecture: “Helping organizations do the right things, right” Ian Charters Distinguished Engineer, FIET (Leader, IBM Worldwide EA Community) IBM Rational Chief Architect, EA and SA Copyright 2009 IBM Corporation IBM Software Group | Rational software Let me tell you a story, about my self-build DiY project… Strategy: “We’re going to have the finest bathroom!” Planning: “It’ll cost this much, and give us all we need” Design: “It’ll look like this – let’s go build it” Development: “Here you are…” Deployment: “…Bingo! Oh dear…” Architecture: “understanding the parts of the whole within its context” Enterprise Architecture: architecture of the enterprise Understanding the enterprise’s architecture leads to better planning and better delivery © 2009 IBM Corporation 2 ian_charters@uk.ibm.com (c) Copyright IBM Corporation 1998, 2009 1
  2. 2. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right IBM Software Group | Rational software Ian Charters, IBM (UK) Ltd Distinguished Engineer, IBM Rational Development (Enterprise Architecture) IBM Executive IT Architect (Senior Certified, IBM Architect Profession) Fellow, Institute of Engineering & Technology For IBM: Working with IBM's clients in establishing or enhancing their architectural capability - whether this be Enterprise Architects helping ensure the definition and planning of viable, robust Business and IT Strategies Enabling their (IT) Solution Architects to more effectively deliver the IT projects that realise these strategies (“Design Excellence”) Co-leading IBM's worldwide EA Community of Practice, helping ensure IBM's own Enterprise Architects have the right skills to do the job With particular responsibility for IBM’s Enterprise Architecture Consulting Method Developing IBM's IT Architecture methods, including the evolution of IBM's formal architecture language the Architecture Description Standard (ADS) “Chief Evangelist”, Enterprise & Solution Architecture, IBM Rational © 2009 IBM Corporation 3 ® IBM Software Group Enterprise Architecture: “Helping organizations do the right things, right” Part 1: Why?

  3. 3. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right IBM Software Group | Rational software In a Nutshell… …EA helps ensure our clients’ IT Strategies are robust (“upstream EA”), and then guides them towards successful delivery (“downstream EA”) Upstream EA (Strategic Planning) Viable IT strategies underpinned by sound architecture thinking Sound architecture thinking inspires viable IT strategies This is a well proven domain of Enterprise Architecture http://mitsloan.mit.edu/cisr But success is only achieved when strategic intent turns into delivery, so… Downstream EA (Solution Governance) Successful portfolio delivery underpinned by sound architecture thinking This is a less well established, but equally valuable domain of Enterprise Architecture When these two come together – it’s an “Actionable EA”! © 2009 IBM Corporation 5 IBM Software Group | Rational software … with the intent of avoiding chaos… … and even if an individual house is well architected, if each house is different (e.g. different electricity voltage, water pressure) then the city will not work… … plus, if the purpose of the building is not clear… © 2009 IBM Corporation 6 ian_charters@uk.ibm.com (c) Copyright IBM Corporation 1998, 2009 3
  4. 4. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right IBM Software Group | Rational software …so that Enterprise Architecture can be thought of as both a link and a chain! Putting it bluntly… “Enterprise Architecture constrains the individual project, for the benefit of the Enterprise” More Positively… “Freedom within the law [without which] the life of man [would be] solitary, poor, nasty, brutish and short.” Thomas Hobbes, 1588-1679 © 2009 IBM Corporation 7 IBM Software Group | Rational software But why bother? What’s the value of an Enterprise Architecture (1)? Fundamentally, it’s about co-operation and co-ordination for the management of risk There are tangible benefits Cost avoidance/reduction Avoid purchase of incompatible architectures Shortened development/deployment time Leverage installed architecture Reduce duplication and waste Prepare for and manage the deployed environment Reduced support and maintenance costs Reduce user support costs Leverage support staff Reduce learning cycle © 2009 IBM Corporation 8 ian_charters@uk.ibm.com (c) Copyright IBM Corporation 1998, 2009 4
  5. 5. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right IBM Software Group | Rational software But why bother? What’s the value of an Enterprise Architecture (2)? But some of the greatest value comes from intangible things Behaviour Common vision & principles between the business and IT Consensus approach serving common goals Promotes healthy discussion bringing issues and concern out in the open Create deliverables and execute processes as an organization Enhanced communications Common language Knowledge Management Centralized design information Organisation of inventory Logical systems models Increased knowledge base © 2009 IBM Corporation 9 IBM Software Group | Rational software Is it possible to quantify the financial value of EA? Estimated Savings and/or cost avoidance Reduces Duplicate Product Implementations $1.5M Analysis of building blocks indicates that approximately 131 current or potential products can be reduced to 32 @ an estimated $5,000 annual cost per product over 3 years Reduces risk that new applications will not meet requirements and be $9.5M terminated $46M 53 new application systems must be developed or purchased during the next 3 years. Assume 10% are false starts and each project costs $1.8M $36M Improves Time to Market for new Applications needed to Grow the Business Assume that (1) not having applications available when needed reduces growth by 5% and (2) potential income growth is 100% per year for 3 years. 2001 IBIT is $103M $40M over 3 years Estimated cost to Implement Enterprise Architecture Engagement $1.3M Staff and Operate Architecture Office and Architectural Review Board $3.7M $6M 7 staff FTE for first 9 months and 6 staff FTE for remaining 3 year period @ $100 per Hour $.6M Purchase tool and Train Staff in its use Reference: IBM Engagement, US Utility © 2009 IBM Corporation 10 ian_charters@uk.ibm.com (c) Copyright IBM Corporation 1998, 2009 5
  6. 6. Enterprise Architecture - helping 9 December, 2009 orgsanisations do the right things right IBM Software Group | Rational software Some specific experiences have explicitely quantified the value of EA © 2009 IBM Corporation 11 IBM Software Group | Rational software Critically, EA’s value propositions are different for different stakeholders in an organisation – it’s critical not to confuse them! The Board Solution Development IT Operations Those responsible for the overall Those responsible for the design The folk who operate the One ROI for the Enterprise's IT and development of IT systems Enterprise's IT infrastructure Stakeholders investments and projects. (aka IT associated with specific business Enterprise Steering Committee) solutions Maximise the overall IT ROI by Minimise project risk and Minimise systems management Three distinct aligning all IT efforts with each integration challenges, challenges and product support other and with the enterprise's maximise value of available IT issues, maximise value gained Value strategic direction skills and resource. (i.e. from IT infrastructure through Propositions maximise chance of success) shared and flexible deployment. “The Bridge” “The Engineers” “The Engine Room” Planning, upstream EA One EA- Governing, Capability downstream EA © 2009 IBM Corporation 12 ian_charters@uk.ibm.com (c) Copyright IBM Corporation 1998, 2009 6
