[ Notes ] Making Architecture Matter

   Before doing enterprise architecture, PLS have well-defined business process and its specific owner. Their role will be similar to Product Owner( a term in Scrum ). He have to develop the process and ensure it up-to-date.

   Making Architecture need to be lived in daily operation process and easy reference to. Stakeholders and IT stuffs are in the same page and system(or tool).
   Some KPIs is used for evaluation an architecture success :
1. the reduce number of database platform
2. increase the operation capacity  to more servers & databases by the same of stuffs
3. the steady growing number of servers and databases w/o hire more people
4. the above situation also applied to network infrastructure / web servers / applications / softwares
5. increase the stability of infrastructure and applications

[與會心得] 企業架構發展與應用研討會 Enterprise Architecture Global Trends And Applications Workshop(2012/12/27)

企業架構 / Enterprise Architecture / EA
[ Definition ]

• What is Architecture ?

According to ISO 42010/IEEE 1471, architecture is a "fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution". 

• The context of Enterprise Architecture : there are 2 principle

1. Drive architectural decisions from business value : alignment Systems Architecture(Application, Data, Technology) to Business Value(Vision, Case for action, Value disciplines)
2. Isolate architecture from infrastructure : isolate Systems Architecture from specific physical implementation(Tools, Vendor products)

• EA components are 4 major architectures

•  Core functions of EA
• Top-Down
• Business Oriented
• Mission -> Strategies -> Business Process -> (Business & IT Alignment) -> Enterprise Architecture
• Technology Oriented
• Enterprise Architecture -> ( Blueprint for integration ) -> Various projects
• Feedback
• EA can drive Business Process Re-engineering
• EA can rethink firm's strategies
• EA can re-position firm's mission    

[ Primary Enterprise Architecture frameworks / methodology ]

1. FEAF : Federal Enterprise Architecture Framework

2. Zachman Framework

3. DoDAF : DoD Architecture Framework

4. TOGAF : The Open Group Architecture Framework

[ Global EA現況 ]

• The rank of EA was 7th at USA 2011 from 13th at USA 2010 as top IT management concerns. (Source:Architecture & Governance Magazine, vol. 6, No. 1)
• South Korea government encourages institutions to adopt EA ( Source:Understanding the Impact of Enterprise Architecture on Connected Government, A Qualitative Analysis, 2010)

[ 台灣推廣EA現況 ]
1. Party

1. a|EA Taiwan group
2. Open Group台灣分會

2. 國際大型研討會

• The Open Group Conference Taipei

3. 政府

• 經濟部委託工研院舉辦首席企業架構師能量建置研訓 : 主要針對各科專主持人, 財團法人培訓, 並於2012/10月舉辦各領域發表會.

4. 未來發展

1. 目前國內只有一位TOGAF認證企業架構師, 未來需要培訓多位的TOGAF認證專業人員, 才有足夠能量推廣EA. 目前國內若需導入EA的顧問, 仍仰賴"進口"(國外專家).
2. 推廣EA到產業界, 目標是政府, 銀行&醫療院所等, 本質上須要永續經營的產業/環境.
• 在下認為可以從"醫療雲"的雲端產業切入, 有效地整合政府/醫療院所/企業的流程 / 資源 / IT系統, 使國民的健康和老年人得以妥善的照護. 建置國家級的醫療企業架構, 可以參考新加坡的案例SGEA.
3. 目前TOGAF的架構相對於國內的以中小企業為主的產業環境, 仍屬龐大. 需要提供一精簡版本以適用於中小企業.
• 關於此點, 在下建議可參考ERP大廠如何分拆大型ERP成為適用於中小企業的版本的實務經驗
