Performance of software development is measured by two major criteria – productivity and quality. While the criteria complement each other, they often present a dilemma for developers to focus on the both facets at the same time. Analyzing data on software development performance collected over a 13-year period from 20 countries, we investigated how three software development factors – (1) work effort, (2) level of user involvement (3) team size– affect the performance of software development. The results suggest that productivity and quality of software development are affected in different – often-conflicting – ways by the three software development factors. The findings provide empirical evidence that the two performance criteria do create dichotomic situations for software developer and require careful attention of project management teams to find the optimal balance between the two conflicting criteria.
The Media Influence on Consumers’Energy-Saving Technology Adoption in Korea:An Empirical Study
구철모,정남호 한국경영정보학회 2016 Asia Pacific Journal of Information Systems Vol.26 No.1
The current study attempts to expand our understanding of the determinants of energy-saving technology (EST) use by focusing on the individual aspects of environmental behaviors. This study integrates the hedonic, normative, and gain goals to explain the causal relationship between users and EST use. By adopting Goal-Framing Theory, this study proposed three individual goal frames in the environmental context: hedonic (perceived pleasurability), normative (social norms), and gain goals (legislative pressure and economic factor). Partial Least Square (PLS) was used to analyze the data from 104 respondents. Eight of the ten hypotheses were strongly supported. We found that social norms, perceived pleasurability, economic factor, and legislative pressure had positive and significant effects on attitude to EST use. Interestingly, we found that media influence did not have a severe effect on perceived pleasurability, and that the economic factor enforces mainly positive attitude to EST. Important theoretical and practical implications of these findings are discussed.
E-Smart Health Information Adoption Processes: Central versus Peripheral Route
구철모,임민경,박기호 한국경영정보학회 2014 Asia Pacific Journal of Information Systems Vol.24 No.1
Our study adopted ELM (Elaboration Likelihood Model) to measure the impact of central and peripheral cues on e-healthcare website behavior and its consequence on perceived loyalty of users. While most of ELM studies did not elaborate the antecedent of both central and peripheral cues, we measured the antecedents of those information processing routes to clarify how technical and quality factors (i.e. information organization, security concern, and website attractiveness) develop the nature of either central or peripheral route. We found that information organization was the main antecedent of information quality presented on the website. Second, the results revealed that website security has a positive effect on website credibility. Third, we also found that website attractiveness was positively associated with website credibility. Fourth, consistent with elaboration likelihood model, the empirical findings suggested that information quality (central cue) and website credibility (peripheral cue) were strong predictors of behavior intention to use health website. Our findings also suggested that behavior intention to use health website significantly influenced perceived loyalty.
소셜 네트워크 서비스의 이용동기와 성과에 대한 실증연구 : 온라인에서의 정체성 표현욕구의 매개효과를 중심으로
구철모,정남호,전유희 한국경영정보학회 2011 한국경영정보학회 학술대회논문집 Vol.2011 No.1
본 연구는 정보기술이 발달함에 다양한 정보통신 기기의 사용이 일반화되고 인터넷의 급속한 확산으로 인하여 폭발적으로 증가하고 있는 소셜 네트워크 서비스(SNS)의 사용자 들을 대상으로 하여 그 사용행태에 대해 실증적으로 검토해 보았다. 소셜 네크워크 서비스의 이용동기와 성과에 대해 온라인 상에서의 자기표현 즉, 정체성 표현욕구의 매개효과를 중심으로 하여 살펴보았는데 먼저 개인의 혁신성과 소셜미디어의 사회적 규범은 온라인 상에서의 정체성 표현욕구에 정(+)의 영향을 미치는 것으로 나타났다. 또한 온라인 상에서의 정체성 표현욕구가 지식공유의 즐거움과 소셜미디어 참여에도 긍정적인 영향을 미치는 것으로 나타났지만, 온라인상에서의 정체성 표현욕구가 네트워크 형성과 유지에는 통계적으로 유의하지 않게 나타남으로써 정체성을 표현하는 것 만으로 네트워크를 형성하고 유지하는 것은 어려운 것으로 조사되었다. 따라서 연구결과 온라인 상에서 정체성을 표현하고 소셜미디어에 대한 적극적인 참여로 이어지게 되면 이것이 곧 네트워크 형성과 유지 및 지식공유의 즐거움에 긍정적인 영향을 미치는 것으로 나타났다.

This research explores early mover advantages and performance in the cyber market based on an empirical test. It also examines whether early mover strategic capabilities are able to adopt mutually cumulative relationship in the cyber market. Early movers such as eBay.com and Amazon.com seem to have been able to defy exclusive relationship between strategic capabilities. Compared with their followers such as uBid.com and buy.com, they have been able to adopt strong focus, differentiation, and cost leadership strategies. The purpose of this paper is to investigate the differences in strategic choices based on the strategic capabilities and performance of online firms between early movers and followers. The study reviews early mover advantages and disadvantages, and a strategic typology based on Porter's model, as well as strategic capabilities based on the sand cone model.
A Study of Mobile and Internet Banking Service: Applying for IS Success Model
구철모,율리아 와티,정남호 한국경영정보학회 2013 Asia Pacific Journal of Information Systems Vol.23 No.1
Understanding success factors in electronic banking is important to helping banks succeed. In this study, we extend DeLone and McLean’s IS success model to the electronic banking by adding trust as a success variable. We tested the extended model by comparing internet banking and mobile banking in Indonesia. Using a structural equation modelling approach. We found that system quality had positive impacts on perceived usefulness and end-user satisfaction for both internet banking and mobile banking. The development of e-banking (internet banking and mobile banking) in Indonesia is in its initial stage. Finally, although we tested for the common method bias to relieve concern, further research may use multiple methods when collecting the data. This study investigated the role of each dimension of IS success in the electronic banking environment. While the original IS success model emphasizes individual and organizational impacts, we have argued that trust is an important indicator of IS impact on an individual socially in the banking industry. The contribution of our study is two-fold. Conceptually, the study is the first to extend the IS success model to the e-banking context. We provide an extension of the updated IS success model by adding trust as an outcome variable in the research model.
