Reports from international lending institutions suggest that investments in the telecommunications sector typically produce up to a 30-fold impact on the economy. Predictions like these have caused several of the emerging economies throughout the world to deregulate their telecommunications infrastructure in an attempt to leverage this economic potential. This case study specifically examines the actions of Globe Telecom from just prior to the 1993 Philippine deregulation through the present. Globe has continued to succeed despite the competition against the Philippine Long Distance Telephone Company, which at one time controlled over 90% of the telephone lines in the Philippines. Globe has been able to do this through strategic partnerships, mergers, and acquisitions. Furthermore, Globe has developed into a leading wireless provider by its effective use of modern information technology.

A major complaint with the Waterfall System Development Methodology is the difficulty gathering all requirements up front prior to development, making it hard to implement customer change requests later in the development cycle. Alternatively, the Agile Development Methodology allows for constant system revisions and improvements, potentially making it hard to budget and plan for the completion of a system. This paper looks at integrating Design Thinking into the traditional Waterfall and Agile system development methodologies. Using the Design Thinking components of empathize, define, ideate, prototype, and test leads to improvement of both the developer and customer experience.

In this paper we propose an XML adoption framework, a corresponding adoption space model, and a probit model of technology diffusion to examine the decision of adopting XML-based applications in the context of electronic business. First, an XML adoption framework is proposed. The framework helps companies examine their current status in the electronic business environment from the perspective of three electronic business domains, namely enterprise intranets, value-chain extranets, and the global Internet. This framework also provides guidelines for companies seeking to understand the potential benefits of adopting XML technology, and then further suggests the appropriate path and proper applications. Second, we propose an XML adoption space model. Considering its current status of IT app...

KMSs frequently rely on keyword searches as a primary mechanism for retrieval. While keyword searches are very helpful to knowledge workers, they have their limitations. To illustrate some of the limitations of keyword searches, a database containing all of the articles that have appeared in MIS Quarterly was constructed. Prior research shows that ambiguous, poorly constructed keyword phrases lead to poor information retrieval results. Knowledge hierarchies have been used to overcome some of the keyword searches limitations. This research proposes the use of dimensional modeling and multidimensional database technologies to implement knowledge hierarchies. It suggests that many of the limitations inherent in keyword searches can be eliminated from knowledge management systems by exploiting the benefits of the hierarchical structure that underlies multidimensional databases.

This paper examines the differences between the optimization techniques that database designers need to consider when developing relational versus multidimensional data warehouses. The multidimensional data storage model allows for large numbers of aggregates to be stored in a very efficient and accessible manner. These aggregates make it possible to not only access information faster, but also at a lower cost in terms of CPU, I/O, and disk space utilization. This research-in-progress demonstrates those speed and cost savings using the TPC-H decision support benchmark. This publicly available dataset is used to contrast the use of indices in its relational implementation with the use of aggregates in its dimensional implementation. These contrasts show why database designers must shift from the index paradigm for relational databases t...

This dissertation will be taking a multi-method approach in its investigation. First, an empirical examination of keyword usage from a representative IS research journal is performed to validate the need for this research. Second, a case study is underway with the Intel Corporation, on their satisfaction with the quality of their information retrieval capabilities. Lastly, a laboratory experiment is proposed to test the informational retrieval accuracy of two types of knowledge management system infrastructure – traditional relational-based and multidimensional-based KMS. Theories developed in cognitive psychology suggest that the hierarchical nature of multidimensional systems, through its aggregation capabilities and tree-like structures, generate more accurate information, faster, and provide more closely related information t...

Seven myths are explored and counter-myths are provided. Three myths focus on consumer value including data collection (privacy), customer profiling, and persuasive (targeted) marketing. Two business value myths focus on productivity and reputation. Two additional myths focus on societal values that include discussion on the economy and environmental issues and finally national security issue. This paper is presented in a discussion-based format designed to further discussion of information ethics in the context of data warehousing practices.

Seeing 20/30: A Visual History of Key(word) Insights from MIS Quarterly

This historical retrospect study contributes to the IS discipline specifically by incorporating visualization techniques on author provided keyword to gather additional insights into the research aspect of the IS field. Thirty years’ worth of keyword data, resulting in approximately 3500 usages, was collected from some 700 MIS Quarterly articles (volumes 1-30 – years 1977-2006) to create both static and dynamic visualizations. These visualizations provide alternative mechanisms for “seeing” the history of the IS discipline. This research finds that while ‘Decision Support Systems’ may (or may not!) have been the single largest topic within MISQ over its first 30 years, keyword synonyms and time are factors in understanding the diverse history of IS research.

This research examines characteristics of knowledge creators by investigating a subset of information systems (IS) researchers, namely those who have published in one of the field's premier journals-MIS Quarterly. Author characteristics (pedigree, gender, various location data, etc.) are examined and reported on. Additionally, with the aid of modern visualization tools such as Tableau and/or Microsoft Power BI, influential scholarly foci (knowledge centers) are analyzed. Findings suggest an increase of women, international scholars, and locations over time, are adding to the richness and diversity of the IS field. Furthermore, this research presents some discussion and presentation of the migratory pattern of IS researchers utilizing dynamic mapping visualizations.
