Managing the diffusion of organizational learning behavior

This paper addresses the need for organizations to manage the transformation from traditional hierarchical models to ‘learning organizations.’ We propose a five-stage methodology useful in the diffusion of behaviors associated with organizational learning (OL) theory. The stages of OL diffusion are (1) agenda-setting, (2) matching, (3) restructuring, (4) clarifying, and (5) routinizing. Each stage involves both managerial (structural) or member (cultural) influences on organizational memory (OM). Salient definitions are provided and the OM aspects and deliverables associated with each OL diffusion stage are discussed. This research provides a theoretically-driven approach to help change agents diffuse and realize the potential of OL behavior in the firm.

A US Client’s learning from outsourcing IT work offshore

Based on 45 interviews and significant documentation, we explore the offshore outsourcing experiences of a US-based biotechnology company. This company offshore outsourced 21 IT projects to six suppliers in India. Senior managers and the official documents from the Program Management Office consistently reported that offshore outsourcing was successful in reducing the company’s IT costs. But interviews with knowledgeable participants actually managing the projects suggest that many projects were not successful in meeting cost, quality, and productivity objectives. We found evidence that this company’s offshore strategy to simply replace domestic contractors with cheaper, offshore suppliers was a poor fit with its social and cultural contexts. Specifically, we found that strong social networks between the company’s internal IT employees and domestic contractors were not easily replicated with offshore suppliers. Furthermore, the internal project management processes were often incompatible with offshore suppliers’ processes. This paper also analyzes seven project characteristics that differentiate highly-rated projects from poorly-rated projects. These project characteristics are type of IT work, size of supplier firm, location of supplier employees (onsite/offshore), dollar value of the contract, duration of the project, timing of the project, and client unit managing the project. The paper concludes with four overall insights for clients and suppliers.

Profiling a decade of Information Systems Frontiers’ research

This article analyses the first 10 years of research published in the Information Systems Frontiers (ISF) from 1999 to 2008. The analysis of the published material includes examining variables such as most productive authors, citation analysis, universities associated with the most publications, geographic diversity, authors’ backgrounds and research methods. The keyword analysis suggests that ISF research has evolved from establishing concepts and domain of information systems (IS), technology and management to contemporary issues such as outsourcing, web services and security. The analysis presented in this paper has identified intellectually significant studies that have contributed to the development and accumulation of intellectual wealth of ISF. The analysis has also identified authors published in other journals whose work largely shaped and guided the researchers published in ISF. This research has implications for researchers, journal editors, and research institutions.

The Use of Context-Aware Policies and Ontologies to Facilitate Business-Aware Network Management

The purpose of autonomic networking is to manage the business and technical complexity of networked components and systems. However, existing network management data has no link to business concepts. This makes it very difficult to ensure that services offered by the network are meeting business objectives. This paper describes a novel context-aware policy model that uses a combination of modeled and ontological data to determine the current context, which policies are applicable to that context, and what services and resources should be offered to which users and applications.

Turnover intentions of Indian IS professionals

One of the major challenges facing the Indian IT services industry is the high rate of turnover among Indian IS professionals. Turnover rates have been reported as high as 100% annually. Despite the serious problem, we are unaware of any academic research that has studied the determinants of turnover among Indian IS professionals. We aim to contribute to the literature by understanding Turnover Intentions of Indian IS professionals. We developed an initial model of Turnover Intentions based on the IS and Organizational Behavior literatures. The most commonly identified determinants of Turnover Intentions in these literatures were Organizational Commitment (emotional attachment to an organization) and Job Satisfaction. However, the research that identified these determinants was primarily tested on Western workers. We assessed the applicability of this model by interviewing 25 Indian IS professionals. We found strong support that Job Satisfaction affects Turnover Intentions among Indian IS professionals. However, Organizational Commitment was found to be a troublesome construct. Many Indian participants did not relate to the concept of an emotional attachment to an organization. Instead, they talked in terms that better mapped to the construct Organizational Satisfaction. The interviews also uncovered another important determinant of Turnover Intention: Social Norms. Social Norms, as evidenced by significant family pressure to reside in the same city as the employee’s family, emerged as a major reason for Turnover Intentions. Our revised model identifies Job Satisfaction, Organizational Satisfaction, and Social Norms as the main determinants of Turnover Intentions among Indian IS Professionals. We also identify four implications for practice. The most worrisome implication for Western clients is that Indian IS professionals do not like performing routine IT maintenance work or merely programming from predefined specifications—the bulk of work sent offshore. Indian IS professionals preferred client-facing activities, design and development work.

Household technology adoption in a global marketplace: Incorporating the role of espoused cultural values

This paper extends prior research in household technology adoption by incorporating the role of espoused cultural values. Specifically, we theorize that espoused cultural values–individualism/collectivism, masculinity/femininity, power distance, uncertainty avoidance, and long-term orientation—play an important role in affecting consumers’ behaviors by altering consumers’ belief structures—attitudinal beliefs, normative beliefs, and control beliefs. Our theoretical model predicts that the impact of consumers’ belief structures on household technology adoption intention varies across consumers with different cultural values. Propositions are provided to explain how different cultural mechanisms moderate the relationships between consumers’ beliefs and household technology adoption intention. The paper concludes with theoretical implications, future research directions, and practical implications.

Evie - A developer toolkit for encoding service interaction patterns

Facilitation of collaborative business processes across organizational and infrastructural boundaries continues to present challenges to enterprise software developers. One of the greatest difficulties in this respect is achieving a streamlined pipeline from business modeling to execution infrastructures. In this paper we present Evie - an approach for rapid design and deployment of event driven collaborative processes based on significant language extensions to Java that are characterized by abstract and succinct constructs. The focus of this paper is to provide proof of concept of Evie’s expressability using a recent benchmark known as service interaction patterns. While the patterns encapsulate the breadth of required business process semantics the Evie language delivers a rapid means of encoding them at an abstract level, and subsequently compiling and executing them to create a fully fledged Java-based execution environment.

Strategic dependence on the IT resource and outsourcing: A test of the strategic control model

Using resource dependency theory (RDT), this research analyzes how organizations control their information technology resources to improve organizational performance. According to RDT, organizations must manage their dependency on external organizations and limit external dependencies when resources are considered critical. The current study proposes and tests a portion of a Strategic Control Model positing that managers seek to control important, strategic resources in order to create value for the firm and to avoid dependency on external entities. Utilizing a research design that captured extensive quantitative data on the control of IT functions and services, the research team gathered 5 years of data on 54 business units (BUs) in 27 global companies located in seven countries. Study examined the linkages of these 54 BUs to firm performance. Locating the Extent of Control within the firm in cases where the firm depends on IT as a strategic resource proves to be a good explanation for effective decisions leading to higher performance. Viewing IT as a strategic resource alone does not lead to positive business unit outcomes, but the moderating influence of Extent of Control is found to establish the complex statistical relationship with business unit performance. For these reasons, it is critical that a theoretically grounded firm-wide process for decisions on locating IT control is in place to capture business value.

History and Status of Operations Support Systems

Operations Support Systems (OSS) have been a critical component of any telecommunications company’s business plan. In this paper we examine the history of OSS from the perspectives of maturing support for problem domains, enabling technologies, and system integration. Finally, we will look at the problems posed by the coming “everything over IP” networks, the changing communications provider landscape and the impact on operations support systems.

Information technology workforce skills: The software and IT services provider perspective

It is now commonplace for an organization to turn to external firms for the provision of IT services and software. As technology advances and the business environment continues to evolve, a key challenge facing IT software and service providers is identifying critical skill sets, both today and in the future. The challenge is compounded as a result of the continuing growth of outsourcing and the increasing demand for technology solutions. This paper explores that challenge through a survey of IT software and service providers. We extend and complement previous studies of non-IT firms by comparing skills sought by non-IT organizations with those of IT services and software providers. Results indicate that, surprisingly, software and services providers place more emphasis on business domain and project management skills than on technical skills. This has implications for the hiring and retention practices of managers, and for academic curriculum and course offerings.

A proposal for a set of attributes relevant for Web portal data quality

Data Quality is a critical issue in today’s interconnected society. Advances in technology are making the use of the Internet an ever-growing phenomenon and we are witnessing the creation of a great variety of applications such as Web Portals. These applications are important data sources and/or means of accessing information which many people use to make decisions or to carry out tasks. Quality is a very important factor in any software product and also in data. As quality is a wide concept, quality models are usually used to assess the quality of a software product. From the software point of view there is a widely accepted standard proposed by ISO/IEC (the ISO/IEC 9126) which proposes a quality model for software products. However, until now a similar proposal for data quality has not existed. Although we have found some proposals of data quality models, some of them working as “de facto” standards, none of them focus specifically on web portal data quality and the user’s perspective. In this paper, we propose a set of 33 attributes which are relevant for portal data quality. These have been obtained from a revision of literature and a validation process carried out by means of a survey. Although these attributes do not conform to a usable model, we think that it might be considered as a good starting point for constructing one.

Evaluation of inter-organizational business process solutions: A conceptual model-based approach

Collaboration and coordination between organizations are necessary in today’s business environment, and are enabled by inter-organizational processes. Many approaches for the construction of such processes have been proposed in recent years. However, due to the lack of standard terminology it is hard to evaluate and select a solution that fits a specific business scenario. The paper proposes a conceptual model which depicts the nature of interaction between organizations through business processes under specific business requirements that emphasize the privacy and autonomy of the participating organizations. The model is generic, and relies on the generic process model (GPM) framework and on Bunge’s ontology. Being generic and theory-based, we propose to use the model as a basis for comparing and evaluating design and implementation-level approaches for inter-organizational processes. We demonstrate the evaluation procedure by applying it to three existing approaches.

Theory of relative defect proneness

In this study, we investigated the functional form of the size-defect relationship for software modules through replicated studies conducted on ten open-source products. We consistently observed a power-law relationship where defect proneness increases at a slower rate compared to size. Therefore, smaller modules are proportionally more defect prone. We externally validated the application of our results for two commercial systems. Given limited and fixed resources for code inspections, there would be an impressive improvement in the cost-effectiveness, as much as 341% in one of the systems, if a smallest-first strategy were preferred over a largest-first one. The consistent results obtained in this study led us to state a theory of relative defect proneness (RDP): In large-scale software systems, smaller modules will be proportionally more defect-prone compared to larger ones. We suggest that practitioners consider our results and give higher priority to smaller modules in their focused quality assurance efforts.

A literature review of electronic marketplace research: Themes, theories and an integrative framework

In this paper, we presented a literature review of the current status of electronic marketplace (EM) research. It consists of 109 journal articles published in 19 journals that are appropriate outlets for electronic commerce research. The results show that an increasing volume of EM research has been conducted from diverse theoretical perspectives. Based on content analysis, we identified eight research themes, five types of methodologies and six categories of background theories which most EM researches were grounded in. By combining research themes and the patterns of the background theories, an integrative framework of EM was proposed to represent the paradigms of EM researches. The framework shows that EM phenomena can be addressed from three perspectives: information systems, inter-organizational/social structure and strategic management perspectives. This framework suggests a parsimonious and cohesive way to explain key EM research issues such as EM adoption, success and impact.

Inverse multi-objective robust evolutionary design

In this paper, we present an Inverse Multi-Objective Robust Evolutionary (IMORE) design methodology that handles the presence of uncertainty without making assumptions about the uncertainty structure. We model the clustering of uncertain events in families of nested sets using a multi-level optimization search. To reduce the high computational costs of the proposed methodology we proposed schemes for (1) adapting the step-size in estimating the uncertainty, and (2) trimming down the number of calls to the objective function in the nested search. Both offline and online adaptation strategies are considered in conjunction with the IMORE design algorithm. Design of Experiments (DOE) approaches further reduce the number of objective function calls in the online adaptive IMORE algorithm. Empirical studies conducted on a series of test functions having diverse complexities show that the proposed algorithms converge to a set of Pareto-optimal design solutions with non-dominated nominal and robustness performances efficiently.

Relating research to practice: imperative or circumstance?

This paper provides a starting point for thinking beyond a research–practice divide and discusses possible new conceptualizations of intervention and the role of IT research in contemporary organizational settings. ‘IT research’ denotes a conglomerate of overlapping research conducted under the headings of Information Systems, Systems Development, Critical IS Research and Participatory Design. The paper applies this joint notion of IT research and the IT researcher to draw parallels across these niches of research regarding the question of intervention. Through an analysis of selected field study events, a prominent notion of intervention (as being active as opposed to being passive) is reworked in terms of intervention as circumstance, a circumstantial interplay of situated practices. In closing, subsequent possibilities for repositioning the IT researcher are discussed in terms of reflexivity, facilitation or being a trickster.

Investigating mobile wireless technology adoption: An extension of the technology acceptance model

This research represents a theoretical extension of the Technology Acceptance Model (TAM), which IS researchers have used to explain technologies’ perceived usefulness and individuals intention to use it. The authors developed a model, referred to as the Mobile Wireless Technology Acceptance Model (MWTAM), to test the relationship between theoretical constructs spanning technological influence processes (Perceived Ubiquity, and Perceived Reachability) and cognitive influence processes (Job Relevance, Perceived Usefulness, and Perceived Ease of Use) and their impact on Behavioral Intention. MWTAM is assessed using data collected from an online survey and analyzed using AMOS 5.0. Results provide evidence to support MWTAM as both the technological and cognitive influence processes accounted for 58.7% of the variance explained in an individual’s Behavioral Intention toward using mobile wireless technology. Additionally, the path coefficients between constructs ranged from 0.241 to 0.572 providing further evidence to support the theoretical extension of TAM.

On detecting faults for Boolean expressions

Fault based testing aims at detecting hypothesized faults based on specifications or program source. There are some fault based techniques for testing Boolean expressions which are commonly used to model conditions in specifications as well as logical decisions in program source. The MUMCUT strategy has been proposed to generate test cases from Boolean expressions. Moreover, it detects eight common types of hypothesized faults provided that the original expression is in irredundant disjunctive normal form, IDNF. Software practitioners are more likely to write the conditions and logical decisions in general form rather than IDNF. Hence, it is interesting to investigate the fault detecting capability of the MUMCUT strategy with respect to general form Boolean expressions. In this article, we perform empirical studies to investigate the fault detection capability of the MUMCUT strategy with respect to general form Boolean expressions as well as mutated expressions. A mutated expression can be obtained from the original given Boolean expression by making a syntactic change based on a particular type of fault.

Motion estimation based color transfer and its application to color video compression

In this paper a novel scheme for color video compression using color transfer technique is proposed. Towards this, a new color transfer mechanism for video using motion estimation is presented. Encoder and decoder architectures for the proposed compression scheme are also presented. In this scheme, compression is achieved by firstly discarding chrominance information for all but selected reference frames and then using motion prediction and discrete cosine transform (DCT) based quantization. At decompression stage, the luminance-only frames are colored using chrominance information from the reference frames applying the proposed color transfer technique. To integrate color transfer mechanism with hybrid compression scheme a new color transfer protocol is defined. Both compression scheme and color transfer work in YCbCr color space.

Context enhancement for co-intentionality and co-reference in asynchronous CMC

The regulative and semantic ‘distance’ of electronic conferencing may impede the topical alignment and the unambiguous interpretation of messages, hindering collaborative learning processes. Compared to a face-to-face environment, in electronic conferencing this distance may be caused by a reduced strength of online ‘context’. Explicitly defining the context of messages in an electronic environment may increase the writers’ co-intentionality and co-reference. An annotation tool is presented, strengthening the context by providing a document under discussion and enabling users to anchor their messages in specific passages of the document. Preliminary results indicate that the tool does indeed reinforce the context, focusing the online discussion around a certain topic (increasing co-intentionality) and providing a frame of reference for single messages (increasing co-reference).
