Many IT architects envision evolvingtheir IT platform to a service-orientedarchitecture (SOA) but find their plansstymied by the inability to demonstrateimmediate business value for SOAprojects. Yes, SOA can yield significant

business value by simplifying integrationprojects, boosting productivity, increasingflexibility, lowering cost of ownership,and better aligning IT operations withbusiness objectives. But the key toachieving these business benefits inthe near term lies in leveraging existingsoftware functionality in new ways. Forcustom development projects, this meansreusing software functions and compo-nents, assembling these pieces in dif-ferent ways, and mapping them more

closely to business activities. It alsomeans minimizing the amount of manu-ally written new code with its associatedmaintenance cost.

Todays tough economic times andintense competition are forcing compa-nies to make more careful fundingdecisions. Businesses are scrutinizingevery investment to help ensure theability to bring rapid benefits and acompelling ROI. Many SOA adoptersare struggling to maintain a sound justi-

fication for continued backing becauseof the time and skill level required todeliver effective SOA-based solutions.For SOA initiatives to succeed, compa-nies like yours must find ways to deliverthe required business applications asproductively and effectively as possible,while minimizing cost and risk.

A key weapon in achieving these goalsis a comprehensive application compo-sition environment that can speed upproject delivery while reducing trainingneeds. A best-of-breed compositionenvironment must offer:

Effective and flexible reuse of existingapplications and services

A productive development environment

Role-based customization to optimizethe productivity of business users

Business process orientation to alignIT operations with business activities

The SAP NetWeaver Composition

Environment (SAP NetWeaver CE)offering has been designed specificallywith these needs in mind.

available adapters, prepackaged integra-tion templates, and support of industrystandards. It also offers enterprise-gradesupport for running an effective SOAby providing an enterprise services busand orchestration functionality that

supports transactions, mediation ofservices, caching, and availability.

ES Repository, delivered as part of SAPNetWeaver CE and SAP NetWeaverPI, provides centralized management ofdevelopment components, includingservice definitions, business objects,user interface definitions, and models.It features a look-up service compliantwith the Universal Description, Discovery,and Integration (UDDI) standard and

allows discovery of published Webservices that can be consumed bycomposite applications. ES Repositoryalso enables you to maintain governanceover SOA development by encouragingreuse of published services and correctversions of development componentsand models.

The services that reside in ES Repositorycome from a variety of sources, such asSAP NetWeaver PI and enterpriseservices bundles delivered as part of

enhancement packages for SAP BusinessSuite. Many services delivered in enter-prise services bundles are developed incollaboration with SAP customers andpartners through industry design groupsthat are part of the Enterprise ServicesCommunity program.

LEVERAGING SAPS FASTER ROUTE TO SOA

PROVEN SOLUTIONS STREAMLINE THEADOPTION OF SOA

Figure 1: Service-Oriented Architecture (SOA) Based on the SAP Portfolio

Before investigating SAP NetWeaverCE in more detail, it is useful to under-stand where it fits into the portfolio ofSOA solutions from SAP. SAP makesthe adoption of SOA more rapid andaffordable by delivering SOA-enabled

applications, the SAP NetWeaver tech-nology platform, and enterprise servicesthat IT can use to integrate existing pro-cesses or compose new ones. Figure 1depicts the implementation of SOAbased on the SAP portfolio.

Service-enabled for greater flexibility, theSAP Business Suite software providesbest-of-breed functionality for runningcore business processes that are easilyadaptable via reusable enterprise ser-

vices. SAP NetWeaver provides thedevelopment tools and infrastructureto deploy a mature service-orientedarchitecture through three main compo-

nents: SAP NetWeaver CE, the SAPNetWeaver Process Integration (SAPNetWeaver PI) offering, and EnterpriseServices Repository (ES Repository).

SAP NetWeaver CE provides all the

tools you need to compose businessprocesses and applications and orches-trate them with services. It also includestools for filling gaps in services byenabling the model-driven developmentof new custom Web services, businessobjects, and user interfaces. Finally, itoffers development life-cycle manage-ment tools for building, versioning, anddeploying enterprise services andcomposite applications.

SOA adoption is no longer a questionof if but when for most companies.According to a Gartner Inc. reporttitled Findings: SOA Survey HighlightsStrong SOL Uptakeby Teresa Jonespublished June 25, 2008, Forty-nine

percent of respondents claim to beusing SOA already, with a further 17%planning to do so in the next 12 months.IT departments know SOA is the archi-tecture that must power their future.However, many IT organizations areunsure how to get there or take on onlysmall projects of limited value due to fearof uncertain ROI and payback times forlarger projects. Such uncertainty is alwaysan issue when starting out with newtechnology such as SOA. But in todays

tougher economic times, ROI has be-come the subject of laser-beam focus.

What does it take to achieve the SOA-enabled vision of flexible business pro-cesses and rapid process innovation?Leveraging the IT systems that underpinbusiness operations, your companyneeds the agility to quickly change its

existing business processes and con-struct new ones. To do this, you needto service-enable these processes andtheir related applications. You also needto build and deploy processes in a sim-ple, modular way to maximize reusability.An ad hoc approach to custom-buildingprocesses without governance or propermethodology can lead to a chaoticarchitecture that fosters expensiveduplication and redundancy and raisesgovernance problems (see Figure 2).

The key to success is to assemble yourSOA based on a clear, standardized

methodology that encompasses theappropriate governance proceduresand tools (see Figure 3). Such an archi-tecture enhances reusability, reducesdevelopment time, and lowers mainte-nance costs.

Once you develop a critical mass ofservices-based business functionality,the reuse of these services lets you

readily adapt existing applications to newrequirements and rapidly compose newapplications, all with minimal new coding.The results are faster deployment, im-proved quality, increased flexibility, lowercosts, closer business alignment, and agreater enterprise-wide standardization.

For SOA initiatives tosucceed, companies likeyours must find ways todeliver the required businessapplications as productivelyand effectively as possible,while minimizing cost and

risk. A comprehensiveapplication compositionenvironment can help youspeed up project deliverywhile reducing training needs.

Targeting the Sweet Spot forApplication Composition

While an application composition envi-ronment promises a powerful rangeof benefits that extract more value

from SOA, some use cases representparticularly fruitful prospects for thistechnology. These sweet spots,summarized in Figure 4, represent thetypes of projects that offer the fastestpayback and greatest ROI when cou-pled with application compositionfunctionality.

These four SOA use cases are ideallysuited to leverage the major benefits ofa best-of-breed application composition

environment: efficiency, flexibility, andinsight (see the table to the left). Thefollowing sections examine each of thesebenefit areas, showing how they helpdrive faster and greater ROI from SOA.

Exception management Resolve exception events

in automated processesand integrated scenarios

User productivity Create new types of user

interaction (portal, analytics,voice, mobile)

User-Centric Use Cases

Edge processes Extend business processes

based on industry bestpractices to collaborate

within and across companies

Increasing the Efficiency ofDevelopers and Business Users

For developers, a smart applicationcomposition environment creates manyopportunities to heighten efficiency. For

starters, developers can address thedifferent architectural layers of compositeapplications (such as user interfaces,business processes, business logic,and data) in a single environment. Thiseliminates the need to keep switchingtools and consolidates the componentsof the solution in one place. A model-based approach brings added efficiencyby allowing developers to extract imple-mentation knowledge from individualprograms and build it into standard

components, enabling even less-experienced developers to reuse func-tionality. And of course, reusing existingbuilding blocks and applications todeliver new business functionality avoidsextra development and testing effort.

At the business user level, higher pro-ductivity is easy to achieve by developingrole-based composite applications.Business users are more productivewith a targeted interface that asks for keypieces of input instead of a one-size-

fits-all screen with unnecessary fields.For example, a field service engineeronly needs a customers address andtelephone number prior to a repair visit;the customers trading history and con-tracts are irrelevant. However, a sales

person needs access to a wider range

of customer information for sales trackingand analysis. With a new interface tunedto their needs, business users makefewer mistakes, while you eliminate theneed for expensive and time-consumingemployee training.

Improving the Flexibility of

IT Solutions

From a business perspective, flexible ITsystems are quick to handle new chal-lenges, swiftly delivering high-qualityservices to business users as needs

Once you develop a critical mass of services-basedbusiness functionality, the reuse of these services

enables you to readily adapt existing applications tonew requirements and rapidly compose new applica-tions, all with minimal new coding. The results arefaster deployment, improved quality, increased flexi-bility, lower costs, closer business alignment, and agreater degree of enterprise-wide standardization.

change. Application composition stronglysupports this goal in two ways. First, itenables developers to assemble newsolutions from the optimal combinationof existing components and newlydeveloped or modified ones. Second,

it allows applications to be expressedin business process terms, making iteasier for business users to understandhow an automated business processworks and explain any changes theyneed.

As an example, consider a bank thatoffers homeowners insurance to cus-tomers. To facilitate this process, theIT team has already composed an appli-cation to check an applicants credit,

track interest rates, and identify riskfactors based on property address. Butwhat if the bank decides to expand intoa new market by offering insurance foryachts? IT can quickly compose a newapplication by reusing the first threesteps of the homeowners insurancecomposite and developing a new stepto assess risk factors for yachts, suchas mooring location. In this way, appli-cation composition enables the bank tobe as flexible as possible in addressingthe new business opportunity. Now

imagine that the bank wants to tightenup on the governance of its insurancebusiness. Because the audit departmentcan see each step in the existing processat a business level (rather than at atechnical level), it can identify where

new audit steps are required in the pro-cess flow. As a result, it quickly realizesthe need to add a step when any insur-ance proposal covering assets greaterthan $1 million is requested.

The ability to create composite applica-tions quickly only comes with SOA ma-turity. Prior to application composition,you need more than available componentservices. You also need the methodologyand governance to develop serviceseffectively and an infrastructure to sup-port the development and deploymentof SOA applications. Many SOA infra-structure vendors with so-called best-of-breed products only provide toolkitsand infrastructure for service building.

In essence, they say, Here are sometools; now use our professional servicesto create the components you need. AtSAP, we take a different approach. Weoffer a complete solution with standards-compliant development tools and anSOA infrastructure. We also provide alarge array of industry-relevant enter-prise services that are inherently partof existing SAP applications.

Gaining Greater Business Insight

The power to align IT closely with busi-ness objectives is a key contributor todriving increased returns from SOA.Because application composition enablesclear business process implementations,it allows greater business visibility into

IT operations. That means your businessusers can more quickly understandexisting processes and how businessoperations are performing. For example,application composition facilitates thedevelopment of an executive dashboard,

offering a real-time, high-level view ofthe performance of key business pro-cesses against targets and identifyingissues needing attention. With this in-sight, business users get the informa-tion they need to optimize processesby adapting them quickly and effectively.This insight also enables business usersto manage by exception that is, tofocus on the 1% of business operationsthat require attention instead of the 99%that are running smoothly.

Software applications representabstractions of business processes.The best practices for creating andmaintaining these applications areshifting from development to compo-sition, using new model-driven toolsand technologies designed to helpbusiness and IT users understand,change, and optimize the perfor-mance of their processes.

In support of this point, research fromJohn Hagel, business strategist withDeloitte Touche USA LLP, and JohnSeeley Brown, cochairman of theDeloitte Center for Edge Innovation

reveals that 95% of IT investment isdirected at business processes intendedto drive down costs. Yet the majority ofemployee time is spent on the exceptionsto these processes, such as blocked

orders, back orders, and the like. Byexamining and clarifying business pro-cesses, you can identify the exceptionsthat bog down productivity and drive upcost. Monitoring tools can now watchfor these exceptions and take action

automatically when they occur, resultingin efficiency gains and higher usersatisfaction.

Greater insight also enables companieslike yours to implement compliance andgovernance policies more effectively. Anapplication composition environmentallows you to introduce a level of stan-dardization across development activitiesenterprise-wide, leveraging the powerof model-based development and utilizing

a common repository for storing allenterprise-related definitions and speci-fications. By enabling a process-orientedapproach and the power to monitorprocesses step-by-step as your ITsystems execute them, an applicationcomposition environment can also alertyour compliance officers to out-of-linesituations when they occur.

A smart application composition environment createsnumerous opportunities to heighten efficiency,

improve flexibility, and gain greater business insight.
