What are the Challenges?

Challenge• Enable visibility to cross

functional KPIs, business events, and process states

Challenge• Enable end-to-end

monitoring and correlation

• Structure around cross functional ownership

System A

Challenge• Evolve from siloed

functional design and build to a cross functional process focus approach

Challenge• Enable

workflow to cross system boundaries rather than be bound to them

Historical Perspective

• Lack of Alignment

• IT centric

• Siloed initiatives

• Lack Cross-functional process owners

• Enterprise Optimization focus is in the wrong place

• We get lost in the details

What should the future look like?

• Enterprise Architecture is about Business Transformation

• Process Modeling is a component of Enterprise Architecture

• Cross-functional optimization is the focus

• Cross-functional process ownership is obvious and rewarded

What should the future look like?

• Strategic Visioning “involves defining the context, identifying strategic drivers, developing a high level business model, establishing principles for the new work system, and packaging for commitment and action.”

• “As part of this visioning exercise, key questions for work reengineering need to be explored: What is your business value network? What are the key functions (logical service units) that are closest to delivering value to the customer?”

• “Any functional component or service unit can be decomposed into a number of interrelated processes and work activities.”

• “Each logical service unit can be modeled to determine the most appropriate business processes and related manual and automated work activities”

Excerpts from Paradigm Shift: The New Promise of Information Technology,by Art Caston and Don Tapscott, McGraw-Hill 1993

Why spend the time?

Why align Business, IT and Process Architecture?

Fact: Mrs. Winchester never had a master set of blueprints, but did sketch out individual rooms on paper and even tablecloths!

Its about the integrated plan……..just ask Sarah Winchester

How do we get there?

• Stop viewing Enterprise Architecture as an IT thing!

• Create a high level reference framework • Identify & define what we do and the services we

provide• Identify & define how we realize the business

services• Identify & define how we provide services and

who owns them• Publish the plan!

What are the Enablers?

• Business Buy-in and ownership• Model Driven Architecture

– Describes the enterprise as a set of related models• Enterprise Service Architecture

– The business services that need to exist– The services they provide– The capabilities that realize them– It’s not just about the technology

• Event Driven Architecture– Describes the enterprise interactions in terms of related events

that trigger services

Yes, these are complementary!

Model Driven Architecture

“A style of enterprise application development and integration based on;

using automated tools,

to build system independent models,

and transform them into efficient implementation”1

Service Oriented Architecture

Bill Hassell - IBM’s Business Integration Reference Architecture, 2004

• “An approach for designing and implementing distributed systems,

• that allows a tight correlation between the business model and the IT implementation”

Enterprise Services Architecture

Business Perspective

• What Services need to exist?• What information do we need?• What Capabilities provide

Services?• What Processes realize a Service?

Implementation Perspective

• What is the process flow?• What is the information flow?• What composite application

functionality realizes as process?

• An approach for designing and implementing capabilities that realize and leverage services,

• that allows a tight correlation between the business model and the physical implementation

An Integrated Roadmap

Adaptive Business Process Management

• Enterprise Architecture is about Business Transformation

• Process Modeling is a component of the Enterprise Architecture

• Modeling the business as a set of interrelated services provides context to Process Modeling
