整合企業流程管理架構與系統開發方法之行動研究，尚孝純 吳雅玲
企業流程管理(BPM)的目的在將傳統管理理論的規劃、組織、協調、管理、控制等分散的思維模式加以整合並融入商業環境中，促使企業快速而有效的完成各項商業流程的設計、整合與再造。然而，這樣的架構雖有宏觀的視野，但在細部的執行規劃上卻顯不足，若無法與資訊技術資源相輔相成，這套企業作業規劃將無法實際開發並落實執行，難以達到企業流程最佳化之目的。此外，系統開發生命週期(SDLC)方法詳細規劃了系統開發目的與步驟，以確實執行系統開發與安裝，但在落實企業策略目標上卻較缺乏慎密的考量。因此，本研究提出整合二者的方法論，並使用行動研究方法，進行整合BPM架構與SDLC方法的驗證與強化。透過行動研究「偵察或觀察」、「計畫」、「行動與監看」以及「反省與評鑑」四大歷程，以螺旋循環的形式在「預支請款流程系統」、「專案管理流程系統」以及「保險契約流程系統」三種不同性質系統進行開發與安裝，反覆地測試與調整本研究之整合性方法。研究結果可以發現SDLC的嵌入，對於流程系統開
發最大的助益在於流程設計與流程實作上，提供了一個完整且實際的作法，亦加速了流程改善與系統開發的效益，使得BPM架構因SDLC嚴謹方法而落實執行。SDLC方法則在BPM架構之下較能有效支應企業目標。目前BPM的發展多止於理論發表，需要實務案例落實該方法的應用，本研究在進行三個案例的實作後，發現應可有助BPM架構與系統開發方法發展成更完善的理論實踐。

壽險業採用行動商務之實證研究，李慶章
蔡秉儒
行動商務泛指使用手持無線裝置，在任何地點來進行購買產品或服務之應用(Luadon
& Laudon, 2006)。經由行動商務帶來的收益預估將會從2003 年的68.6 億美元成長到2008 年的5,543.7 億美元(http://www.telecomtrends.net)。行動商務被認為是行動工作者提昇工作效能與效率之利器，許多行動工作者亦開始接受與採用行動商務系統。台灣壽險業務員的人數相當多，壽險業者對行動科技之採用也非常積極，因此壽險業使用行動科技的行為，可以作為行動商務系統使用行為之參考指標。本研究探討影響壽險業採用行動商務系統之因素，研究結果顯示，(1)績效預期、心力耗費預期、社會影響都會影響壽險業務員使用行動商務系統的意圖，其中以心力耗費預期的影響效果最大；(2)壽險業務員實際使用行動商務系統之行為會受到使用意圖的影響，但不會受到助益環境因素的影響；(3)只有年齡及性別因素會干擾績效預期對使用意圖的影響，使用經驗及自願性不會干擾壽險業使用行動科技的意圖及行為。研究結果可以幫助壽險及相關產業規劃及導入行動商務，也可以協助資訊科技業者開發設計及推動行動商務系統。
關鍵詞：意圖、行為、行動商務、整合的科技接受與使用理論。

使用知識價值附加法衡量資訊科技委外之績效，吳有龍
楊倍箕
為了在競爭激烈的環境裡獲取優勢，資訊科技委外是企業所常採用的模式之一，企業界也普遍認為資訊科技委外是一種能夠節省成本、降低總體花費的最佳方式。而在過去之研究，較少有相關文獻或研究探討資訊科技委外後各流程，其所蘊含之知識量與報酬率，是否有所改變。因此本研究以Housel & Bell 所提出之知識附加價值法(Knowledge
Value Added, KVA) ，將資訊科技委外前後各流程所內含的知識加以量化，並比較其差異，作為資訊科技委外之績效評估。
藉由KVA 法之學習時間與流程描述來估計流程內的知識量，對三家上市公司進行深度訪談，並輔以公開之財務報表進行成本分析，以獲得各部門KVA 值，進而取得知識報酬率(Return of Knowledge,
ROK)。研究結果發現，資訊委外對於企業，除節省成本、降低總體花費外，在各流程所蘊含之知識量與報酬率，亦會相對逐年漸漸提高。藉此明確之具體化數據，可促使管理者在考量資訊科技投資時採用委外方式之意願，並可使企業專注於核心資源之經營，進而提升企業整體之經營績效。
關鍵字：資訊科技委外、知識附加價值法、知識報酬率。

組織導入BS7799後之資訊安全管理成效研究，黃明達 徐 正
在台灣，2006 年4 月已經有81 家組織導入BS7799 資訊安全管理系統。近年來，相關的研究都是以探討單一行業、個別領域與個案公司方面為主，目前較缺乏探討各不同行業別、不同領域的組織導入BS7799 後，其成效分析之實證研究。因此，本研究探討的就是當ISMS（Information Security Management
System）導入組織一段時間後，資訊安全管理上的成效議題，即BS7799 導入組織後在資訊安全管理上的成效。
本研究是透過2005 年12 月底中華民國台灣地區在ISMS 國際機構業已註冊，通過BS7799 認證的組織共計66 家來進行問卷調查。研究BS7799 導入後，其不同組織行業別、導入部門範圍別間，資訊安全管理上實施的成效。最後歸納出的結果顯示：1.導入後，74%的組織資訊安全事件有減少；2.各組織的資訊安全控制領域皆有改善，當中以「資訊安全政策」、「營運持續管理」與「實體與環境安全」改善成效較高，「資訊安全政策」領域內的控制措施A5.1.2 改善成效最佳；3.「資訊安全事件管理」與「資訊系統取得開發及維護」是改善成效比較偏低的領域，可作爾後組織導入BS7799 時的參考。

社會大眾對RFID 應用於醫療方面之接受度研究，謝順金 周士傑
隨著Wal-Mart 宣布導入RFID 後，全球便陷入了一股RFID 的熱潮。而RFID 的特性也使得醫療業對於RFID 充滿興趣。若能夠瞭解大眾對於RFID 系統的接受程度並且加強宣導RFID 相關知識，那麼對於RFID 於醫療方面的推廣與應用一定會有正面的幫助。
本研究主要探討RFID 系統的系統品質與資訊品質以及個人創新接受度等因素，是否會影響民眾對RFID 系統的認知有用性、認知易用性、態度與使用意願。本研究於國內已導入RFID 的醫院之院區進行問卷調查，共回收208 份有效問卷，並利用線性結構關係法(LISREL)進行分析研究。
本研究結果顯示存取方便性與效率性、安全性、資訊品質、創新接受度、認知有用性、認知易用性與態度皆為影響使用意願的重要因素，其中又以態度的解釋能力最高，其次為認知有用性、認知易用性、創新接受度、存取方便性與效率性、資訊品質以及安全性。由此可見，醫療業者在導入RFID 系統時，若能將上述因素加以考量並多加強RFID 相關知識的宣導，便能夠提昇大眾對於RFID 系統的接受度。

Abstract
Building a
Composite Model of Business Process Management with System Development
Life Cycle: An Action Research on Multiple Systems
Shari S. C. Shang
Ya-Ling Wu
Business process management (BPM) methods are used to analyze, assess,
and design business processes. Although they are praised for business
alignment and adaptability, this kind of methodology is in its initial
stage and has its shortcomings with regard to detailed system development
and execution. On the other hand, system development life cycle (SDLC) methods,
though lacking a cautious consideration of business strategies, carefully
examine functional goals and provide detailed guidelines for system development
and implementation.
To operationalize
the BPM methods and to enhance the applicability of SDLC methods at a
higher business level, it would be beneficial to examine features of
these two methods and propose a proper model with complementary features
being incorporated.
By applying action research, this
study empirically validated and enhanced the proposed integrated BPM/SDLC
method through detection, planning, action, and monitoring, as well as the
reflection and evaluation processes. During this action research, a
spiral cycle of model development, modification, and enhancement was
adopted with the installation of three different kinds of systems. The
research result is a composite model that elaborates upon both the BPM
and SDLC methods and focuses on business process management success.
Study findings reveal that the most significant benefit of the
involvement of SDLC for business process management is to provide a
complete and practical framework with instruments and guidelines for an
executable process system.

An Empirical Study on the Acceptance and Use of Mobile
Commerce in Life Insurance Industry
Ching-Chang Lee
Ping-Ju Tsai
Mobile commerce is generally defined
as use of handheld wireless devices for purchasing goods and services
from any location (Luadon & Laudon, 2006). Revenues generated from mobile
commerce are forecasted to exceed US$554.37 billion in 2008 from US$6.86
billion in 2003 (http://www.telecomtrends.net). Mobile commerce is
considered to be able to help mobile workers in increasing their work effectiveness
and efficiency. Many mobile workers begin to adopt and use mobile systems.
The
number of insurance agents in Taiwan is relatively larger
than that of othercountries. The insurance
industry in Taiwan
also prompts the adoption of mobile commerce systems positively.
Therefore the adoption behaviors of insurance industry can be considered
as the index of mobile commerce adoption behaviors in Taiwan. This
research investigates factors that affect the adoption of mobile commerce
systems in insurance industry. Research results find that the performance
expectancy, effort expectancy and social influence of insurance agents indeedly can predict
their intention in using mobile commerce systems, and the effort
expectancy has the largest predictive effect. The behaviors of insurance
agents in using mobile commerce systems can be predicted by intention but
can not be predicted by facilitating conditions. Only the influence of
performance expectancy on intention will be moderated by gender and age,
and the other influence relationships will not be moderated by all
moderate variables. The research findings can help insurance industry and
related industries in planning and implementing mobile commerce systems,
and also can support information technology industry in designing and promopting mobile commerce systems.

The Performance and Efficiency Evaluation of the IT Outsourcing
— Using the KVA Method
Yu-Lung Wu
Pei-Chi Yang
In
order to obtain the advantageous position in an environment with keen competition,
Information Technology (IT) Outsourcing is one of the models that the enterprises
usually adopt. Generally the enterprises also believe that information technology
outsourcing is the best method to save the cost and lower the overall expenditure.
But in previous studies, there are not many related literatures or
studies that would consider each of the flow paths after information
technology outsourcing, and evaluate whether there is any change on its
knowledge amount and rate of return. Therefore this study uses the
Knowledge Value Added (KVA) method, which is addressed by Housel &
Bell, to quantify the knowledge that is contained in each flow path
before and after information technology outsourcing. Then the differences
are compared for performance assessment of information technology
outsourcing.
The
learning time and flow path description of KVA are used for the
estimation of knowledge amount within the flow paths. To obtain the KVA
value and Return of Knowledge (ROK) of each department, in-depth
interviews are carried out with three listed companies and their public
financial statements are used to assist with the cost analysis. The
result of the study found that besides cost saving and lowering of the overall
expenditure, the information technology outsourcing can also gradually
raise the knowledge amount and rate of return within each flow path year
by year for the
enterprises.

The Study of the Effectiveness of Information Security Management
after Organizations Implement BS 7799
Ming-Dar
Hwang
Cheng
Hsu
As of May 2006, eighty four
organizations in Taiwan
have implemented BS 7799 information security management systems. The
related researches in the recent years mostly discuss the BS 7799
implementation issue in terms of one single industry field, a specific
domain or individual cases. It is lacking to find studies which
investigate the effectiveness of implementing information security
management system (ISMS) in terms of organizations across different
fields. This paper focuses on the across-the-field effectiveness after BS
7799 is implemented into organizations.
Based on the survey of the sixty
six organizations in Taiwan
which have registered in the international ISMS user group, this paper
examines the diverse domains and controls in implementing BS 7799. The
findings of this paper are as follows. In general after organizations implement
BS 7799, the information security events in seventy four percent of these
organizations have decreased. This shows that most organizations have
improved their environment of information security. Furthermore, the
organizations gain improvement in most control objectives, and become
remarkably secure in the “security policy”, “business continuity management,”
and “physical and environmental security” domains. In the “security
policy” domain, implementing the A5.1.2
control achieves an outstanding effectiveness. Nevertheless,the outcome also reveals the lower
implementing effectiveness in the “information security incident
management” and “information systems acquisition, development and
maintenance” domains.

A Study on the Mass Acceptance of the RFID Systems Applied in
Medical Practices.
Dr.
Shun-Chin Hsieh
Shih-Chieh Chou
As
the Wal-Mart announces that they will implement the RFID system, the
whole world is surrounded by the RFID wave. It must have a positive
impact to spread and apply the RFID system in medical practices if we
could grasp the acceptance level of people about the RFID system and make more propaganda about the knowledge of RFID.
This
study mainly discusses the factors impacting perceived usefulness,
perceived ease of use, attitude and intention in the following three
aspects: system quality, information quality and innovativeness. Based on
the paper-based questionnaires, the study had accepted 208 effective
responses from people around the hospitals that have implemented the RFID
system. The questionnaires collected are processed by LISREL for further
analysis.
Our
studies show that convenience of access, safety, information quality,
innovativeness, perceived usefulness, perceived ease of use and attitude
are the key factors promoting the intention. The attitude has the most
influence on the intention. The following influence factors in order are
the perceived usefulness, perceived ease of use, innovativeness,
convenience of access, information quality and safety. By paying more
attention to the factors listed above and conducting more propaganda
about the knowledge of RFID, the hospital operators will be able to raise
the acceptance level of RIFD in medical practices.
Key words: RFID, TAM, Innovativeness, LISREL

Collaborated Construction and Sharing of Domain Knowledge
Using Ontology

Since
the information technology has been developed so fast, searching the
related knowledge or information in specific domain is much easier than
before. However, the amount of returning information is usually too large
and the relations between the handling objects are usually complicated.
The users can only process the collected objects, or documents, based on
the basic properties such as document name or publishing years. It is difficult
for a user to manage all the deep knowledge involved based on the information
mentioned or discussed within the document. However, in order to master
the overall concepts of the particular domain, it is necessary for the
user to be able to actually study the article and understand the real
contents of it and then, somehow, to record the structures and relations
of the knowledge which he has mastered after reading and understand the
contents elaborated in the documents. If we can classify and describe the
related information easily, it would help the researcher to grasp the
whole picture of the domain and enhance the quality of his work.
In this research we have shown how
a researcher can improve the effectiveness of his study by easily
building up the complete domain ontology and specifying the concept and
the relations between the research articles in a structured way. The
structure of the research domain is following a specific ontology which
is determined before the experiment. The users are allowed to present the
relations between the ontology objects in the articles by calculating the
weightings and visualizing the arranged data to show the complete domain
framework. The visualization is done by drawing relational diagrams based
on the user’s query. This permits the user to master the overall concepts
of the interested domain. The total framework is implemented on the web
for easy accessibility. This approach of domain knowledge analysis
provides more precise information about document relationships.
