What is Business Driven Development ?

Service Oriented Architecture

Business Driven Development Lifecycle

Trends that impact software and systems development

TRADITIONAL CURRENT REALITY

Co-located teams

BUSINESS TRENDS


5

Geographic distribution of business―the new norm

Near-shore Internal staffingDirect ownership

OffshoreSubsidiaries Joint partnershipsDirect ownership of foreign

facilities and hiring of employees

OutsourcedService providers assume

responsibility for life-cycle processes

Executive needsRisk managementPerformance measurement

Development needsProject and portfolio accountabilityProcess traceability and visibilitySecure, tamper-resistant environment

Global impact of local regulationsHIPAA, 21CFR11, Sarbanes-OxleyBasel II, EASHW

Global standards ISO 900x, Six SigmaCOBIT, COSO, ITILCMM/CMMI, SPICE (ISO 15504)

Accommodating compliance―the new necessity


7

Open computing―a new route to collaboration and innovation

Open standards Improve data sharing by simplifying

integration of disparate technologies

Open architecture Increase collaboration by easily

extending business processes

Open sourcePromote innovation by leveraging

community development

Open architecture

Open computing


8

Modular systems―greater flexibility

Maximize investments―reuse componentsLeverage existing assets and investments Avoid rip and replace

Increase flexibility―interoperable systemsConnect and share business componentsEasily distribute business processes

Accelerate initiatives―scalable and agileAdd capacity or functionality quicklyScale technology based on business demands Increase business process efficiency―globally

Today, service-oriented architecture (SOA) takes business process automation to the next level
