Where We Are HeadingCase Study: Procure to Pay Process

IBM Software Group


More pragmatic approach to re-engineering effortsIncremental deploymentsTied to tangible business benefits

Each function where it best meets business needs:Within the organizationFrom a business partnerCompletely outsourced

Tune ongoing business without widespread disruption: optimize in isolation

Why is this Scenario Desirable?

IBM Software Group


Monolithic systems and applications can’t be reused

Ad hoc integration is difficult to change/maintain

Lack of standards limits interoperability

Rigidity makes small improvements hard to justify

Component Business Models Permit Change

IBM Software Group


Business Components

Business performs activitiesEx: Rent vehicle

Activities use resourcesEx: Rental car, parking spot, agent

A business component is a set of activities and resources

Ex: Rental location owns cars and rents and checks in carsIt is a virtual business unit that can operate independently

IBM Software Group


Dependencies among Components

Activities depend on other dependenciesResource usageControl and information flows

Goal: restrict dependencies among componentsRegroup activities and resourcesChannel them through services

IBM Software Group


Services

A service is an explicit interface with no “back doors”

Service has a defined contractInputs and outputsInteraction protocolPerformance

Components linked by services are substitutable

IBM Software Group


A Business Component Map is a tabular view of the business components in scope.

Step 2: Define a Service Model • Identify services based on business components• Make decisions based on architectural criteria

Step 3: Implement a Service Architecture• Develop a service-oriented architecture to support

the componentized business

Step 1: Break down your business into components• Decide what is strategically important• Prioritize and scope your transformation projectsCBM

Implementation Component Modeling

MDA

IBM Software Group


Service Oriented Architecture (SOA)Flexible connectivity:

Represent application or resource as a service with a standardized interfaceEnable exchange of structured information(messages, documents, ‘business objects’)Mediate message exchange through a connectivity layer (enterprise service bus)Provide on-ramps to the bus for legacy application environments

Combines new and existing applications to address changing business needs

Facilitates the management of business performance, quality of service, and dynamic monitoring

IBM Software Group


SOA Defining Concepts Universal Connectivity: Integrates most diverse environments, bridging protocols, languages, platforms, APIs and messaging paradigms – providing scale and scope of integration required by today’s extended enterprise

Service Orientation:Facilitates loose coupling

between software components

Incremental Integration: Start small and plug in capability to enrich your implementation as

needs dictate

Open, standards-based:Open APIs and protocols support the

interoperability and substitution of middleware from multiple vendors

Event Orientation:Decouples applications that

publish business events from subscribing

applications

Flexibility:A variety of options

for persistence, reliability, security,

availability...Deploy where

required, manage centrally

Automated toolsModeling toolsTranslators

IBM Software Group


Problem Domain Models

Syntax and semantics for a particular purposeCapture business-level contentMore intuitive syntax

Reduce mindless repetitionPredefined control and data patternsEliminate repetitious control specification

Two approaches:UML ProfileDomain specific language (DSL)

Architecture

Decomposition into subsystems

Topology

Interaction rules

Data formats

Resource management

Hooks for future extensions

Scaffolding for testing

IBM Software Group


Architecture FrameworkFramework = reusable architecture pattern

Includes:Skeleton execution environmentPredefined subsystems and topologyInteraction and data rules, formats, interfacesAttachment points for plug-insComponent libraries of useful functionalitySample applications

Integrated development environments (IDE)Eclipse, .NET, J2EE

IBM Software Group


Framework Advantages

Enable domain specific languages (DSL) to optimize repeated patterns

Ensure consistency

Excellent for incremental design

Enforce design trade-offs

Supports static and dynamic analysis

Iteration

Common baselineNo divergent versions or schedules

Specific goalsSet priorities by adjusting goals

Specific deadlineAll iterations about the same length

At the end of an iteration:Check in everythingBuild an executable systemTest and examine itReevaluate priorities

IBM Software Group


Iterative Development Process

Series of iterations allows mid-course corrections

Executable releases permit constant evaluation

Attacking problems early reduces risk
