Innovating with SAP Enterprise Service Content- a Practical GuideDerek Wood –LS Computing

A CLEAR NEW AFRICA

What is SOA?“Service-oriented architecture is a best-practice architecture pattern for the systematic design of request/reply applications. Its primary intentions are business-level software modularity and rapid, non-intrusive reuse of business software in new runtime contexts.” - Gartner, Introduction to Service Oriented Architecture, 2003

“Service-oriented architecture is a design style for maximizing service sharing, reuse, and interoperability in distributed environments.” - Burton Group, Service-Oriented Architecture: Developing the Enterprise Roadmap, 2004

“A service-oriented architecture is a framework for integrating business processes and supporting IT infrastructure as secure, standardized components –services – that can be reused and combined to address changing business priorities.” - IBM, Service-Oriented Architecture (SOA) Compass, 2006

“Service oriented architectures (SOA) is an architectural pattern which requires all exposed functionality to be published as services in a platform-independent manner. These services can be consumed by other applications.” - SAP, Enterprise SOA development handbook 1.1, 2008

What is SOA?A Service-Oriented Architecture is a collection of services that communicate with each other

Services expose functionality using a clearly defined method and interface

Services are self-contained and do not depend on the context or state of another service

Work within a distributed systems architecture

Enterprise services are "a standards-based way of encapsulating enterprise functionality and exposing it as a reusable business service that can be combined with other services to meet new requirements. Enterprise services, defined by SAP and its partners and customers, can be assembled together to compose new applications or enable new business processes." (Source: SAP)

"A business process (such as order processing) is a set of logically related activities performed within or across an organization to fulfil a defined business objective." (Source: industry term.)

What is an Enterprise Service?

ES Content is pre-packaged integration content, which is created based on the SAP SOA design methodology

This business content includes global data types, service interfaces, models, and mapping definitions

IT professionals can use this pre-delivered content from SAP to jump-start their SOA implementations

Before You Start - Some Figures

Only 37% of current SOA projects demonstrate ROI

SOA touches only 27% of current IT projects in the average organization

Only 32% of published software services get reused

By 2010, < 25 percent of large companies will have the sufficient technical and organisational skills necessary to deliver enterprise wide SOA. (Gartner)

60% of organizations will adopt SOA, and by 2010 it will be used in 80% of new system architectures

IDC forecasts that corresponding software expenses will constitute about 11 billion dollars

Why do SOA Projects Fail?

SOA is considered to be a standard project There needs to be a change in mindset

2nd tier talent is often used Often do not have the right mindset

Under resourced Need budget to invest in long-term gains

Vendors often define the solutions Business needs to drive solutions

Requirements are not fully gathered Need to have a holistic view to reap benefits

Technical Issues

Underestimating the technical complexity of a large-scale SOA

Insufficient validation or understanding of the SOA enabling technical infrastructure

Insufficient SOA infrastructure monitoring

Too-coarse / too-fine service granularity

Insufficient / out-of-date documentation

Lack of attention to impact of implementing SOA

Insufficient change management for the IT service organization

Not leveraging integration/SOA competency centre

Thinking SOA projects should be run like any other

Not anticipating service growth in a maturing SOA

Outsourcing architects (or not having them at all)

Overlooking governance

Organisational Issues

Dealing with the Issues

Technical Invest in the right resources & tools

Invest in training & professional

services

Demand SOAGovernance

Organisational Invest in Architecture

Acquire appropriate skill

sets and train internal resources

Demand SOA Governance

(Design time and runtime)

Governance is Critical

The analysts all agree that SOA Governance is key

But...

... enthusiasm for SOA and its anticipated benefits results in some companies taking risky shortcuts in establishing robust governance, service development disciplines and staffing

There is no “one size fits all” approach governance, too little or too much governance will kill an SOA project, companies need just enough governance (Gartner,2007)

SOA Governance

SOA Policies

SOA Organisation•The organizational structures, roles and responsibilities necessary for SOA Governance

SOA Maturity•The governance required at each level of SOA Maturity

SOA Infrastructure•The technical infrastructure available to support SOA Governance

SOA Process•The processes that need to be followed to establish governance, set and monitor policies

It is required for any enhancements to SAP Content It is a very capable ESB both SAP to SAP and SAP to non-SAP

Final Words

Start small - think holistically

Align with the organization (culture, structure, maturity)

Manage expectations internally as well as externally

Identify and involve all stakeholders from the start

Let the business process be key, not the technology

Get the right skills in place – business, architecture & technical

Process and services drive the project

Start with a process that matters but isn’t critical

Invest in Governance to save costs later
