In the Beginning, Architecture was Simple…

… and evolved slowly

Transport Technology Helped Communities to Emerge…

… and grow


Better Infrastructure Fostered Denser Communities…

… and more of them


So How Do You Organize and Manage All This?

How do you ensure you get the business results you want?The desired business benefitWithin cost constraintsWhile preserving the flexibility to address tomorrow’s needs

i.e. avoid the “big dig” and evolve gracefully


Today’s Business Processes Involve Many Systems

EAI and ETL tie systems together

Patterns of interaction define business processes

Where’s the Process?

Anything can talk to anything, but…

The relationship between business processes and systems is obscure

The IT infrastructure is fragile

Difficult to manageCostly to maintainDifficult to evolve

IT becomes a burden, not an asset

SOA and BPM Refine This Structure

Introduces a separation between processes and servicesExplicitly identify a business process as an architectural concept

Processes are assembled from servicesIdeally, the same service gets used in multiple business processes


For Success, A Total Architecture Perspective is Required

Acknowledge different types of processesUnmanaged Processes

Components/services are “hard wired” together to form the actual processOne component’s results become the inputs to the next componentProactive monitoring and breakdown recovery is required for high availability

Managed/Orchestrated ProcessesOne component coordinates the work of other components and servicesManager can monitor process statusThe process of starting the manager is always an unmanaged process!

Vision


Separate processes and presentationSometimes you want to make the same process available via different channels

Avoid duplicating the business rulesSome of the channels may not be conventional presentations

May provide web-service accessIn such cases, you want to make the process itself into a service

Accessible from a variety of presentation components

Vision


Governance at work!

The intent of this slide is NOT to show process, but only key project roles and activities

OrganizationVision


3 key leadership roles needed on every project

Projects that span multiple silos need to include team members from across all silos


Multiple projects require time and the Sponsor does not typically have the time to directly oversee these


So what’s needed in terms of organizational structure?

Enterprise ArchitectureHas cross project and process view needed for solution deliveryResponsible for:

Infrastructure architectureSystems architectureData architectureOperations architecture

BPM CoE / Project OfficeHas the cross-silo view needed for solution deliveryManages silo-spanning projectsDirector must

Have political cloutBe a mediator who can navigate the political landscapeBe empowered to make decisions Directly liaison with the business

BPM CoE and EA are both critical groups in delivering solutions


Total Architecture Summary
