Emissions and Resource Usage
![Page 4: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/4.jpg)
Introducing NOPERU
• National Organization for Permits for Emission and Resource
Usage
• Commercial enterprise, government agency or a private person
requires permit for non-trivial activities (‘fair use’)
• Permit application processing takes from three weeks up to two
years, including appeals
• The process can end with:
– A permit, free of charge
– A permit provided some for of fee or tax is paid
– Rejection
• During the process, NOPERU may require an applicant to
provide additional information
![Page 5: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/5.jpg)
Introducing NOPERU
• NOPERU has five regional branches with three
departments each: commercial, governmental, citizens
• Interactions with NOPERU are on paper or through fax
and telephone; responses are only given during office
hours

Introducing NOPERU
• NOPERU has decentralized computer facilities: local application &
database instances with on-site staff
• NOPERU’s applications were developed in the early 90s and have
undergone several upgrades
– Some are Oracle Forms, all run on Oracle Database (11g)
• Each sector has a very similar system for the permit application
process
– they all stem from the same base application
– then after cloning were independently developed
• The applications are unattractive and have a steep learning curve
– They provide a window on data – not a wizard style, task driven UI
![Page 7: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/7.jpg)

Business Objectives Go Forward 2010-2018
• Faster processing of permit requests
• 24/7 availability (the shop is always open for customers)
• Multi-channel (web portal, mobile, …)
• Ban on paper – everything digital
• Self-service (type in yourself, verify yourself, lookup yourself, …)
• Flexible change process with short time to market
• Cost reduction
• Improve Data Quality
• Shorter learning curve for new employees
• Automate as much of the permit application process as possible
![Page 8: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/8.jpg)

IT Objectives
• Work under ‘enterprise architecture’: structured, planned, controlled
• Consolidation
– Data
– Applications
– Infrastructure
• Leverage industry standards and open technology components
– Use standard applications (COTS) whenever possible (buy before build)
– Never build generic, non-business specific components
• Work with a small number of strategic vendors (that take responsibility)
• Setup Master Data and Information Lifecycle Management
– Data integrity
– Archival procedures
![Page 10: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/10.jpg)

Vendor & Technology Selection Vendor Requirements
• Vendor and Technology/Product are a package deal: you select one and the other
• Small number of strategic, committed vendors
– Ideally taking responsibility for results
• Proven technology with verifiable references
• Products that are strategic to the vendor
• Vendors with enough substance
• Products that are open and support industry standards
– And run on common platform
• Products with substantial community support
– Partners, specialists, books and educational resources, active forums, social media
activity, user groups and conferences
![Page 23: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/23.jpg)
23
Vendor & Technology Selection Process
• Phase 1
– RFI
– Market Analysis
– Peer investigation
• Screening => Short List
• Phase 2
– Proposal and plan – what, how, (creative) conditions
– Presentation of Customer References and Product strategy & roadmap
– (Reference Visit)
• Selection
• Negotations => Deal or No Deal
![Page 24: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/24.jpg)

25
Open ends
• Portal and Mobile technology selection are kept separate
– The decoupled architecture allows for this distinction
• Identity Management & Security is also deferred
– The OPSS (Oracle Platform Security Services in WebLogic Server) make this a
viable option too
![Page 26: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/26.jpg)

IT-Organization 2.0
• Agile Software Development
– Frequent delivery
– Continuous feedback to and prioritizing by business owner
– One team with designers, developers, testers
![Page 27: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/27.jpg)

IT-Organization 2.0
• Training & Coaching program
– Bring in experienced consultants to do and show how to do (enabling is key)
– And to apply best practices and to avoid pitfalls
– Set up Competence Centers (virtual expertise guilds)
• The Platform is crucial
– Database and Middleware (Application Server, Enterprise Service Bus, Process
Engine, …)
• Quick time to market requires break down of walls between Development, Administration and Maintenance
• => DevOps
![Page 31: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/31.jpg)

testing)
– Database: SoapUI, QCTO, DB Unit, SQL Developer
• Build: Ant, Maven
• Deploy: Hudson
• Incident Management and Scrum backlog management: Jira
• Source Control: Subversion (Git?)
• Collaboration & Knowledge Sharing: MediaWiki, Sharepoint, MS Lync (IM)
![Page 37: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/37.jpg)

Project Roadmap
• B2B Corporate Sector – automated exchange; central db and replication with regional instances
• Digital Documents (central content server, internal application used from regional offices)
• UI for internal staff – sector Citizens – ADF, CRUD style (central DB)
• Forms 11g upgrade (from Forms 4.5 Client Server); regional instances
• Portal for Corporate clients
• Mobile app for internal managers (developed by outsourcing party)
Future:
• Standard Application for CRM
• BPM for process approach (operational insight through dashboard, process improvement, integrated document flow)
![Page 38: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/38.jpg)
Learning experience & conclusions
• Consolidation has made a huge difference
– Far less administrative effort, much faster upgrades/rollouts, easier
‘cross the board’ reporting
– Central infrastructure becomes a crucial element whose failure impacts
thousands of users => special attention is required
• The transition is scary and overwhelming
– Guidance, reassurance, explanations, and almost spiritual
support are absolutely necessary to motivate and enable staff
in almost every role
• Communication is essential for the success of the kind of rapid
evolution NOPERU is going through
• Database is [still] hugely important (for performance, integrity,
development) – that is sometimes overlooked
![Page 39: A case of Fusion Middleware - iLOUG 2013](https://reader035.fdocuments.net/reader035/viewer/2022081404/5598b8f01a28abc14a8b4572/html5/thumbnails/39.jpg)
Learning experience & conclusions
• Scrum has made a huge difference
– Flexibility, team commitment, real time insight, business link
• SOA requires up-front investments
– Reuse can only happen when there are reusable assets
– Bookkeeping & Project Accounting enters a new realm as well
• Governance of reusable assets should quickly be
established across the teams
• Layered Architecture and Encapsulation ensures that
teams can work in parallel, legacy can be wrapped and
reused and local optimizations can continually be applied
– Chunks of Work can be outsourced fairly easily

Summary
• Many organization share similar objectives, predicaments and
solutions
• Common requirements:
– Multi-channel, flexible, 24/7, cost efficiency, lower risk, paperless
– Consolidation, standardization, under architecture, decoupling
• Layered, decoupled architecture – upside down piramid
• Common Technology: (for example from Oracle)
– Enterprise Service Bus, BPMN process engine, Digital Content
Management, Enterprise Database
– Tools to quickly create modern UIs for various channels
• Organizational changes:
– Agile software development approach – close cooperation between
business and IT => “embrace change”
• Roadmap: frequent, small steps with business value
