Inter-operability

IncreasedVendor

IncreasedFederation

Federation

13-5-2016

IncreasedFederation

So what is it?Services establish a uniform contract layer that hides underlying disparity, allowing them to be individually governed and evolved

How do I get it?It accomplishes this through the widespread deployment of standardized and composable services each of which encapsulates a segment of the enterprise and expresses it in a consistent manner

Intrinsic Interoperability

13-5-2016

IncreasedIntrinsic

Inter-operability

So what is it?Services within a given boundary are designed to be naturally compatible so that they can be effectively assembled and reconfigured in response to changing business requirements

How do I get it?Interoperability is specifically fostered through the consistent application of design principles and design standards

Vendor Diversity Options

13-5-2016

IncreasedVendor

DiversityOptions

So what is it?A service-oriented environment is based on a vendor-neutral architectural model, allowing the organization to evolve the architecture in tandem with the business without being limited only to proprietary vendor platform characteristics

How do I get it?By designing a service-oriented architecture in alignment with but neutral to major vendor SOA platforms and by positioning service contracts as standardized endpoints throughout a federated enterprise

Business and Technology Alignment

13-5-2016

IncreasedBusiness

andTechnology Alignment

So what is it?Some services are designed with a business-centric functional context, allowing them to mirror and evolve with the business of the organization

How do I get it?This is accomplished by incorporating a structured analysis and modeling process that requires the hands-on involvement of business subject matter experts in the actual definition of the conceptual service candidates

Return On Investment

13-5-2016

IncreasedROI

So what is it?Most services are delivered and viewed as IT assets that are expected to provide repeated value that surpasses the cost of delivery and ownership

How do I get it?Additional up-front expense and effort is invested into every piece of solution logic so as to position it as an IT asset for the purpose of repeatable, long-term financial returns

Organizational Agility

13-5-2016

IncreasedOrgani-zationalAgility

So what is it?New and changing business requirements can be fulfilled more rapidly by establishing an environment in which solutions can be assembled or augmented with reduced effort by leveraging the reusability and native interoperability of existing services

How do I get it?Services have been positioned as reusable IT assets so they can be repeatedly composed into different configurations. As a result, the time and effort required to automate new or changed business processes is correspondingly reduced

It Burden

13-5-2016

Reduced IT Burden

So what is it?The enterprise as a whole is streamlined as a result of the previously described goals and benefits, allowing IT itself to better support the organization by providing more value with less cost and less overall burden

How do I get it?By consistently applying service-orientation

So Now What?

SOA Governance Program

• The Problem so far:• Hardly any business involvement• Project Driven• No “big picture” to shape projects

• To get cohesion, projects need to be part of a SOA Governance Program

SOA Governance Program Office

• A group (or department) that assumes the responsibility of defining and administering the various parts of an SOA governance system
