leverage
• design for leverage: improve quality, consistency, and performance through: – the use of standards
– focus on interoperability
– focus on shareability
– robust security mechanisms

evolveability
• design for evolveability: ensure that a sound migration path exists from the current to future versions of software architectures.
![Page 18: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/18.jpg)
simplicity
• design for simplicity: enable less-skilled participants to create and maintain solutions. improve productivity, and facilitate the speed of architectural and design changes.
![Page 19: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/19.jpg)
serendipity
• design for serendipity: serendipity is the pinnacle of flexibility. architecture should not only facilitate known flexibility needs, but should also strive to enable emergence and innovation that is yet unknown.

twin goals
…based on the ideas of Andy Kyte from Gartner.

end-to-end
• USPO
–University Strategic Programmes Office
• P3M methodology
–Portfolio, Programme, and Project Management
![Page 23: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/23.jpg)
end-to-end
…and/with:
• Service Domain Strategy Templates
• Application Portfolio
• Information Management

p3m end to end
![Page 25: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/25.jpg)
end-to-end
• Vertical scalability is essential – design and delivery teams must use consistent
templates for artefacts when working on USPO and non-USPO initiatives
• Horizontal dockability is essential – artefacts must be extendable to become more detailed
as they progress through the stage/gate process
![Page 26: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/26.jpg)
end-to-end
• Enterprise Architecture – involved more intensively earlier in the process
– responsible for repository management
– responsible for identifying solutions
– responsible for high-level solutions design
– co-facilitates each stage’s discovery festival
![Page 27: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/27.jpg)
end-to-end
• Challenges – the process is still being confirmed
– few initiatives have pass through the process
– the “discovery festival” is sometimes a hard sell
– P3M culture and templating
– time, engagement, and change
– project-recoveries and pre-business-case work
– under-the-radar initiatives
– recognising non-USPO initiatives equally
– consensus on the #entarch takeaways
![Page 28: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/28.jpg)
end-to-end
• Benefits – formalised certain #entarch involvement
– much-improved governance of change
– much-improved visibility of change
– the “discovery festival” works really well
![Page 29: #entarch in end-to-end change-friendly capability delivery - University Library · 2011-12-05 · project costing integration buildings and spaces integration accommodation service](https://reader034.vdocuments.net/reader034/viewer/2022050323/5f7d8415a462fc0e2d73b33e/html5/thumbnails/29.jpg)
refooting the practice
• Environmental changes – organisational restructure
– organisational need
– new senior management
• Auckland’s EA is becoming – more traditional
– more strategic
– differently trusted

2. Total Cost Savings (TCS) – intervention in projects and ensuring reuse
3. Percentage Of Spend That's Strategic (PSTS) – strategic investment vs tactical investment
4. Common Services Compliance Rate (CSCR) – stop buying server-bound storage – use the middleware platforms
5. Architectural Due Diligence Rate (ADDR) – projects and changes coming through EA governance
6. Sunset Technology (ST) – TIME model and application portfolio management
7. Business-Specific – delivery times, quality of service, higher-education KPIs

gartner metrics 2
• Enterprise Technical Architecture metrics
• begin with basic metrics, get sophisticated later
• include cost-savings attributed to #entarch
– somehow, using an agreed technique
• compliance and throughput metrics are easier to establish first
• metrics indicating reuse:
– conceptual alignment: principle alignment
– logical alignment: product match
– physical/implementation alignment: product-set configuration and platform reuse

summary
• we’re becoming less maverick
• organisational change is widespread
• optempo and pace increases down the stack
• baseline metrics are essential
• #entarch must earn/pay its way
• #entarch must be adaptive
• #entarch is a long-term practice
• #entarch is a force for good
