Agenda

•Understanding SOA and Its Benefits

•Preparing for Discovery

•Looking for SOA Application Patterns

•The Workshop Example Business Case

•Conducting Discovery

•Relating SOA Benefits

•Summary


“Service orientation is the single most important design strategy issue for application

delivery teams, and it will remain so for the foreseeable

future.”

- Forrester Research


Technology Challenges Stifle Business Progress

•Monolithic (Silo) Applications•Overlapping process support•Poor integration•Redundant infra-structure investments

•Limited reuse of existing investments•Slow and expensive to change•Ceaseless complexity


Service OrientationAdvances the Business

•Increases Core Business Flexibility•Faster response to business•Consistent view across channels•Reduces costs and timelines•Improves process consistency•Increases business - IT alignment•Reuse existing applications


What is Service Orientation?

•Solutions derived from business processes

•Processes decomposed into business services

•IT Services: self-contained, independent functional units

•Service-oriented architectures, Internet standards, and Grid solutions

Business strategy and technology infrastructure for IT-enabling business processes to adapt to

changing business demands.

Workshop Business CaseIntroduction

Company: Greenfield Nurseries

Industry: Horticulture

Primary business: Supplier of container grown plants

Primary customers: Home Depot, Lowe’s, Target, Wal*Mart

Project priorities: Implement Scan-Based Trading as required by Home Depot

Other Considerations: - Scan-Based Trading is an industry changing event

- Inventory management is a critical process

- Multiple inventory apps located across the country

- SBT must rapidly adapt to changes from all the major retailers


Discovery Levels

Level 1 Discovery: Problem Definition

Level 2 Discovery: Business Deep Dive– Narrow the focus

Level 3 Discovery: Technology Understanding

Business DepthLevel 2 Discovery

•Seek more detail in specific areas•Focus where customer indicates need•Probes should target…

– Specific business processes (inefficiencies, inconsistencies, errors, costly, slow, manual)

– Interaction and process support for constituents (multichannel)

– Specific applications (gaps and deficiencies in support for processes)

– Overlapping or duplicate process and support

– Lack of visibility into operational areas

– Low productivity [lack of automation], redundant tasks

– IT complexity (many technologies/skillsets, app to app integration)

– Applications not aligned with business needs


Level 2 DiscoveryExamples

“Tell me more about the __________ process.”

“What should I know about the ______ application.”“What is important about ______________.”

“What is your perspective on ______________.”


Workshop Business CaseLevel 2 discovery

“What should I know about Scan-Based Trading and Greenfield Nurseries?”

“Without an effective Scan-Based Trading solution, we will no longer be able to do business with Home Depot.

We need to use our current applications and overlay them with SBT capability.”

Asset reuse,

Scalability,

Business responsivene

ss

“We must quickly rollout a solution to trial locations and expand support to nationwide within 6 months.”



“You said SBT is largely about inventory management? How are your inventory management processes and applications affected by the new business model?”

“We need a clear picture of store level inventory… Without accurate information on store inventory, product shelves will be empty. That means we are losing business.”

Improve operation

al visibility,

“As far inventory applications, we have 3. We plan to consolidate. For now they are all important and support different geographies.”

Appl isolation, retiremen

t



“So an accurate view of store inventory is important. Tell me how you use that information”

“Store inventory is important to guide the replenishment process. Today, our reps review the inventory, create a sales order and fax that to the office at a later time.

Improve process

efficiency

This is slow and we sometimes create errors keying in the orders. The errors often go undetected for a long period”



“Your current focus for Scan-Based Trading is Home Depot. What do you expect from other retailers?”

“We also must plan for supporting Scan-Based Trading with other retailers. Home Depot is the first but we expect other retailers to follow soon. We need a process to quickly provide SBT support for others, with special processing rules for each retailer.”

Process flexibility

Adaptable

business rules



“So you need to support new retailers quickly once they initiate SBT for their suppliers. How would you respond to such requests today?”

“No. We typically can’t change our systems fast enough. The business will pull together some manual processes to support each new retailer while IT works on application changes.”

Reduce business-

IT gap

“Once the IT systems are modified, we’ll drop the manual efforts.”


Technology UnderstandingLevel 3 Discovery

•Seek “under the covers” technology understanding

•Technology to applications mapping

•Build and deployment architectures– Java, .NET, ‘C’– Messaging (JMS, MQ, Custom sockets, etc.)– Hardware, Operating systems– Databases– Custom, Third-Party applications


Technical RequirementsLevel 3 Discovery

Key Technical Requirements (KTR) derive from Key Business Requirements

"Systems should be available 24x7" (BR17)

"Need fault-tolerance" (TR6)

“Greenfield Nurseries needs to put in place systems and processes for subscription and transaction billing.” (BR19)

“Implement service metering for billing Scan-Based Trading service users” (TR9)


SOA DiscoverySummary

•Discovery is an information gathering dialogue with the customer•Be prepared with understanding of SOA Dimensions and Application Patterns•Establish Dialogue, Understanding, and Trust

– Level 1 Discovery: Business Understanding– Level 2 Discovery: Business Deep Dive– Level 3 Discovery: Technology Understanding

•Derive SOA Solution
