臺灣資訊產業發展情形 (1/6)

我國資訊國力硬體強軟體差友善列印【聯合新聞網記者祁安國／報導】 IDC 昨日公布今年最新的全球「資訊社會指標」 (Information Society Index) ，我國在全球排名第 20 ，但在亞太地區不如香港、新加坡、韓國，我國號稱是資訊大國，可是這次公布的排行榜，透露出台灣只靠「硬」、欠缺「軟」，資訊教育和普及率在亞洲四小龍中敬陪末座。

Summary of Organizational TrendsFor organizations that began their CMM-based

SPI effort in 1992 or later, the median time to

move from:maturity level 1 to 2 is 22 monthsmaturity level 2 to 3 is 19 monthsmaturity level 3 to 4 is 25 monthsmaturity level 4 to 5 is 13 months

軟體有下列幾項特性– 看不見– 高技術持續翻新– 度量非常不容易– 知識密集– 自動化工具欠缺– 人員能力成熟度影響至鉅

進度、品質、成本管控困難

22


企業為何需要導入 CMMI(by 林榮珍中冠資訊 )

– 全球化的競爭– 軟體將是一切產業的基礎建設– 資訊科技運用邊際效益的逐漸衰退– 企業間資訊整合是必然的趨勢– 企業必須再提昇資訊運用的效用，以縮短企業經營

反應的速度– CMMI 是確保軟體品質及效率的有效方法

23


對軟體工程人才培養的期許(by 林榮珍中冠資訊 )

– 軟體工程能力比技術能力的培養還重要– 訓練文件製作的習慣– 注重分析及歸納能力的訓練– 學會溝通及談判技巧– 整體的思考，但注重細節

24

CMMI 的誤解 (1/7)

1. Creativity vs Process Creativity is one of the important themes for Nation

al scale projects. – One common misperception is that process is somehow the enemy of creativity. Thi

s is wrong. Process is not the opposite of creativity; it is the opposite of chaos.

Process creates discipline and repeatability by putting individual activities into a precise framework.

When organizations have process perspective, they can focus their creativity where it belongs in the content of their work rather than on the structure of their work

25


2.Moving from ML 1 to ML 3 - Skip ML 2 At level 2, the focus is on projects. At level 3, two additional generic practices are implemented by level 2

process area – GP3.1 Establish a Defined process– GP3.2 Collect Improvement Information

At level 3, the emphasis shifts to the organization.– Best practices are gathered by MA( a long period) across the

organization (ML 2).– Processes are tailored as appropriate.– Engineering (RD, TS, PI, VER, VAL), Infrastructure (OPF, OPD, OT), Project (RSKM, Engineering (RD, TS, PI, VER, VAL), Infrastructure (OPF, OPD, OT), Project (RSKM,

IPM), Support (DAR)IPM), Support (DAR)– The organization supports the projects by establishing:

Common processes -Common processes does not necessarily mean one process. (Menu of Processes)

Common measurements Training

26


3. Moving from ML 3 to ML 5 - Skip ML 4 ML4: Organizational Process Performance (OPP) and Quantitative

Project Management (QPM) GG 4: Institutionalize a Quantitatively Managed Process

– GP 4.1: Establish Quantitative Objectives for the ProcessGP 4.2: Stabilize Subprocess Performance

The process Performance Baselines include:– Individual process elements (ex. Rest-case inspection element, ML 2

and ML 3 )– Sequence of connected processes– Processes that cover the entire life of the project (Req. Management)– Process for developing individual work products

27


4. CMMI for ODM/OEM ( Ex. India)– Japan is the Model – Better Quality, Inter

national Business,...

5. Small Organization– CMMI fit in the Small Organization – Tailoring– Collaboration of Companies– See SEI Report – Organization Size

28


6. CMMI Appraisals Status Misconception

Branch Achieved CMMI ML 2 Only

All Company Achieved CMMI ML 2??????

29


7. SCAMPI Practices Implementation Indicator (PII) ex. Affirmations– It is not answers to a pre-defined question

s– How CMMI work was done in the Organiza

tion Unit (OU) rather than the correct answers to the CMMI questions

– CMMI Practices

30


8. Tools vs CMMI 通過 CMMI 評鑑 Collect “process requirements” for support tools an

d investigate possible short-term and long-term tool solutions.

工具是配合各流程使用，僅是『輔助』工作，流程的制定、產品開發設計能力的培養更為重要

Tools are neither a necessary conditions nor a sufficient conditions for OU 通過 CMMI 評鑑

31

未來規劃與建言 (1/9)

1. Establish & Maintain Government Source Selection and Contract Process Monitoring

成立專家團隊發展 Light-Weight CMMI 的委外作業與合約流程監控指引 (Real-Life Example : NASA JPL Template)

對政府採購人員提供了解 CMMI 的訓練選擇並執行先導計畫以獲得得執行 Light-Weight C

MMI 委外作業與合約流程監控的經驗建立與執行知識有價

5. 加強國際化，引進國外計畫讓臺灣具有 CMMI 認證的公司能夠有機會接受案子

– Ex. Promote Out-Sourcing Opportunity from USA to Taiwan’s CMMI 認證的公司

– III, ITRI and Chunghwa Telecom.should provide the driving forces ex. Any project 60% outsourcing to industry
