Antecedents and determinants of information technology habit

IT researchers have recently distinguished habits from prior behavior frequency. We expanded this research by examining habit's antecedents and investigating the simultaneous effect of habit and prior IT use on continued IT use. We found that the research model was relatively robust over four specific use activities of one software application. Indeed, prior IT use, satisfaction, and importance significantly influenced IT habits. Also, while prior IT use predicted continued IT use in the combined data set, habit only predicted continued IT use for activities with higher habit levels. Practical implications are discussed.

Instant Messaging (IM) Usage Continuance for Knowledge Sharing

Previous studies had introduced Expectation Confirmation Model of IT Continuance (ECMIT) and Extended Expectation Confirmation Model of IT Continuance (EECM-IT) as models available for explaining the continued IT usage behavior. Based on Hedonic Information Systems Acceptance Model (HISAM), this study try to extend both of models by add perceived enjoyment (PE) as post-adoption belief. IM continued usage intention for knowledge sharing in college is the focus of this research. Based on a survey of 126 college students consist of undergraduate (S1) and postgraduate (MSi) students at faculty of economics Gadjah Mada university who have ever got assignation of usage of IM for doing knowledge sharing by the lecturer, the SmartPLS analysis indicate that all hypothesizes which proposed in models can be supported. Model validity as a whole also tested and shown good enough result with goodness of fit index equal to 0,6. In this research, perceived enjoyment is found to have strongest influence to satisfaction and continuance usage intention of IM for knowledge sharing is compared perceived usefulness (PU) and perceived ease of use (PEU). This finding is become important implication in development of knowledge management system especially in college.

Understanding continued information technology usage behavior: A comparison of three models in the context of mobile internet

This study examines the utility of three prospective models for understanding the continued IT usage behavior. The three models include: Expectation-Confirmation Model in IT Domain (ECM-IT), Technology Acceptance Model (TAM), and a hybrid model integrating TAM and ECM-IT (extended ECM-IT). Based on a survey of 1826 mobile Internet users, the LISREL analysis shows that all three models meet the various goodness-of-fit criteria. When compared using special indices for differentiating among alternative good models, TAM has the best fit to the data followed by ECM-IT, and the extended ECM-IT. In terms of variance explained for intention to continue IT usage, the extended ECM-IT has the highest R 2 (67%) followed by TAM (63%), and ECM-IT (50%). We conclude that TAM is the most parsimonious and generic model that can be used to study both initial and continued IT adoption; the extended ECM-IT explains continued IT usage behavior as well as TAM; and both the ECM-IT and extended ECM-IT models provide additional information to increase our understanding of continued IT usage.

Business continuity and outsourcing – moves to take out the risk

The mass migration of key business processes and services to Asia has been driven by pressure on organizations to maximise profits and drive down costs. In the outsourcing rush, though, risk and business continuity issues often get overlooked. Although dealing with people from differing cultures, and sometimes with a variable network infrastructure, there is less of a mystique about setting up sound business continuity processes with an outsourced supplier than many believe. Existing principles and disciplines apply to outsourcing in the same way as they have done for any other organizational change. Most organizations begin the process of outsourcing by drawing up contracts, service level agreements and budget expectations. This stage is usually completed at great pace in order to gain maximum strategic advantage. But a power outage in a server room in one country can stop all offshore users from accessing the IT services. Has this been considered? A business continuity manger from one of Europe's largest insurance companies navigates us through the journey. Opportunities for the outsourcing of key processes or services are constantly being explored as organizations strive to maximise profits and drive down costs. Financial and strategic advantages support the business cases whilst IT, risk and business continuity managers hurry to reassess the risks and challenges their teams face in maintaining compliance with their respective standards.

All systems go?

In today's uncertain times more than ever organisations must protect themselves against failures, disruptions, disasters – and be able to resume operations following such events. John Lawlor shows how to prepare an IT continuity plan
