5. From Desktop Applications to Network Solutions
Try … applying Scrum in truly larger scale
• Why not … tackle real world complexity?!
• Try … Scale team work
• Try … Scale agile coaching
• Try … Scale product owner work
• Try … Self-organizing teams
• Try … Scale architecture work
• Try … Deploy and maintain product
• Try … Cross the product borders
• Try … Product Solutions in Scrum
• Try … Customized Projects in Scrum (based on Product Solution)
• Try … Reverse Path (generalize Product Solution from Projects)

6. What‘s the Buzz
• Solution Oriented Architecturesand Process Automation
- Enabling Customization, Reuse, Scalability
• SOA Evolution Roadmap
– Implementation : Point-to-Point Integration Loosely Coupled Services
Abstract Business Services Service-Oriented Business Applications
Enterprise SOA
– Return on Investment (ROI) : Reduce integration costs Reduce Redundancy
& Increase Customer Value through Service Reuse Increase Visibility &
Control Empower the Business Improve Business Agility
• Process Frameworks, e.g.
– IBM: SOMA traditional
– ORACLE: AIM traditional, incremental
– NSN: Solution MoO agile, traditional
,
• IT Governance SDLC – Service Development Lify Cycle
• SaaS
• Hosting Cloud Computing
• BPM – Business Process Modelling

8. Best Practice – Single Product
• Scale team work Area Teams, SoS, Cwiki, WebEx
• Scale agile coaching Scrum Master Sync
• Scale product owner work Area PO
• Architecture work System Architect Support Team
• Deploy and maintain product Continuous Shippability, CI
• Self-organizing teams LowPass BumbleBee

10. Best Practice – Product Solution
• Scale team work Solution Scrum of Scrum (iwi)
• Scale product owner work Solution Architect | PO
• E2e testing Solution Test Framework
• Deploy and maintain solution Solution CI & PET & Stability
• Scale architecture work System Architecture Sync

11. Guiding Framework
• Evolve Domain Specific Industry Standard*
– Business Processes and Activities ( e.g. eTOM)
– Common Data Model (e.g. SID)
• Top Down Design
– Business Process Modelling, Conceptual Meta Data Model
– Derive Human Task/GUI Workflow, Business Process Orchestration
(e.g. BPEL), KPI Gathering, Data Mapping, Functional Worksplit
– Interface Contracts (assertions for violating invariants)
• SDLC Checkpoints per iteration (DONEness check)
– Business/System/Service Requirements DONE (Entry Criteria)
– Solution Architecture Prototype / RefactoringGuidance Update DONE
– Service Design, Build, Test, Deploy DONE (e2e)
– Approval of e2e demo and deliverables by APO and Architect
*TMForum NGOSS: SID = Shared Information/Data Model, eTOM = enhanced Telecom Operations Map (business process and activity descriptions)

13. Customizing Projects
• Staggered Iterations for Project Teams
– Product charge@universal Version n, iterations = GA-x | GA-x+1 …| GA
CustomerProject GeeMobile, iterations 1, 2, …
CustomerProject WireLess …
CustomerProject ReGenesis …
– Product Version n + 1
…
• Solution charge@enterprise Version m, iterations = Solution GA-y | Solution GA-y+1 …| Solution GA
Example: hybrid solution
– Product „agile“
– Product „traditional“ iterative generic customization
– OEM Product „agile“
– OEM Product „configure me or work-around“ iterative setup
Solution CustomerProject Jakarta HQ, iter. 1, 2, … Business Process Customization
Solution CustomerProject Seattle HQ … Business Process Customization

14. Outlook
• Business Process Modelling
– APO demo Requirements / simulated Solution Userstories
– Teams & System Architects give feedback and approve DONEness
• Use KPI per iteration to
– track Business Value created (simulated and real implementation)
– analyse Value Hotspots
– reorder Backlog
• Reverse the path for Solutions
– <= x Customer Projects Derive generic Product Solution
• Multi-Vendor Reference Projects
– e.g. TMF Catalyst
