Achieving IT‐based synergies through regulation‐oriented and consensus‐oriented IT governance capabilities

This study aims at exploring the IT governance capabilities that enable organizations to achieve IT‐based synergies. Following existing work on the contextualization of theories and drawing on the resource‐based view of the firm (RBV), we develop an RBV of IT‐based synergies in two steps. First, we adopt existing context‐specific constructs and relationships from prior work on IT governance capabilities, IT relatedness, and synergies to develop a preliminary contextualization of the RBV. Second, to further refine our theoretical framework, we conduct an exploratory field study that includes interviews with 26 CIOs and other IT executives from 21 multibusiness firms. Our findings suggest that IT governance capabilities lead to IT‐based synergies through IT relatedness and business process relatedness. We found regulation‐oriented IT governance capabilities (IT roles and IT processes) to increase IT relatedness, while consensus‐oriented IT governance capabilities (IT groups and relational capabilities) had a positive effect on business process relatedness. Our results suggest that, in isolation, IT and business process relatedness lead to IT cost synergies, while collectively enabling IT‐induced business synergies. Our study is among the first to treat IT relatedness as an endogenous construct and to explicitly integrate business process relatedness into the IT governance domain. Our context‐specific decomposition of IT governance capabilities helps to better explain their links to IT and business process relatedness. These findings contribute to a better understanding of the tension between IT‐based synergies and business‐IT alignment. Decision‐makers are guided in developing IT governance capabilities to achieve IT‐based synergies.     

IT‐mediated social interactions and knowledge sharing: Role of competence‐based trust and background heterogeneity

In the knowledge‐based economy, organizational success is dependent on how effectively organizational employees share information. Many studies have investigated how different types of communication activities and communications media influence knowledge sharing. We contribute to this literature by examining increasingly prevalent yet understudied IT‐mediated social interactions and their effects on knowledge sharing among employees in comparison to face‐to‐face social connections. By integrating the literature on knowledge sharing, social networks, and information systems, we theorize the ability of IT‐mediated social interaction to (1) afford interactions between individuals with heterogeneous backgrounds and (2) facilitate frequent IT‐mediated social interactions that are high in competence‐based trust—both supporting effective sharing of knowledge. Through a social network analysis of the employees in a high‐tech organization, this study finds that IT‐mediated frequent social interactions are the most effective in promoting knowledge sharing.     

Managing schema evolution in a container‐based persistent system

Managing schema evolution is a problem every persistent system has to cope with to be useful in practice. Schema evolution consists basically of supporting class modification and dealing with data objects created and stored under the old class definitions. Several proposals have been made to handle this problem in systems that follow a full orthogonally persistent approach, but, until now, there has not been any proposal to support it in container‐based persistent systems. In this paper we describe a schema evolution management system designed for Barbados. Barbados is a complete programming environment which is based on an architecture of containers to provide persistent storage. Barbados does not provide full orthogonal persistence, but, as will be described in this paper, its architecture has several other advantages. Among them is the fact that this model is especially suitable for solving the schema evolution problem. Copyright © 2002 John Wiley & Sons, Ltd.

An integral system‐ergonomic approach for IT‐based process management in complex work environments by example of manufacturing and health care

Recent trends in manufacturing and health care move these two work systems closer together from a system ergonomics point of view. Individual treatment of products, especially patients, by specialists in a distributed environment demand information technology (IT)‐based support suitable for complex systems. IT‐based support of processes in complex systems is difficult due to the lack of standard processes. IT support also means to rethink processes to use efficiency potentials. Close cooperation of users and software developers is needed to increase the ergonomic quality of the system. Therefore, suitable tools are needed: UML is available as the standard industry modeling language, Zope/Plone as the quasi‐standard for content management systems, SimPy as an object‐oriented simulation tool for event‐triggered processes, and ACT‐R as a powerful cognitive architecture for simulation of human information processes. The integration of these tools enables system‐ergonomic support of processes in the complex work system as well as of the development and deployment process. It is the base of an integral system‐ergonomic approach for IT‐based process management. Knowledge gained during process analysis either enters models or leads to the extension and adaptation of the tool chain. The models serve as basis for discussion among system ergonomists, programmers, and specialists from the work system. Further, they are understood by simulation and process support tools. Transcoding efforts between humans with different professional backgrounds and machines are reduced, and the flexibility demanded by complex systems is met. © 2008 Wiley Periodicals, Inc.     

Design and Experimental Evaluation of a Discrete‐time ASPR‐based Adaptive Output Feedback Control System Using FRIT

This paper describes the design of an adaptive output feedback control system in discrete‐time, based on almost strictly positive real (ASPR)‐ness with a feedforward input. It is well‐known that an adaptive output feedback control system based on ASPR conditions can achieve asymptotic stability via a constant feedback gain. Unfortunately, most realistic systems are not ASPR because of the severe conditions. The introduction of a parallel feedforward compensator (PFC) is an efficient way to alleviate such restrictions. However, the problem remains that there exists a steady state error between the output of the augmented system and the output of the original system. The proposed scheme provides a strategy wherein the feedforward input is utilized such that the steady state error is removed. Furthermore, the fictitious reference iterative tuning (FRIT) approach is employed to determine the control parameters using one‐shot input/output experimental data directly, without prior information about the control system. This paper explains how the FRIT approach is applied in designing an adaptive output feedback control system. The effectiveness of the proposed scheme is confirmed experimentally, by using a motor application.     

Towards a Guideline for Design of a Corporate Entrepreneurship Function for Business Development in Medium‐Sized Technology‐Based Companies

The speed with which global high‐technology markets evolve makes companies recognize that an effective innovation process is the best way to guarantee competitiveness. However, when (medium‐sized) companies then wish to set up a corporate entrepreneurship function to enhance business development processes, they can find little material available in literature to assist in such processes. In this article we have described a guideline and some backgrounds for creating a corporate entrepreneurship function to realize business development in a high‐tech context.

The Development of Science‐Based Products: Managing by Design Spaces

The design of science‐based products (SBP) combines three main issues: exploring a functional space, producing scientific knowledge about key phenomena related to the concept and ensuring manageability of the project. Literature on the subject generally considers the three issues to be irreconcilable, on the grounds that a project involving functional exploration and phenomenological exploration is unmanageable. However, based on two SBP cases, we show that this apparent unmanageability is mainly a result of the lack of a relevant managerial model for the interpretation of the observations. We introduce the notion of ‘design space’ as a collective working place where designers can act to learn about what they want to learn (for their overall design process). We show that the design of an SBP is managed as a sequence of design spaces.

Design of a cavity‐based filtering antenna with dual‐polarization operating at Ka‐band

The contribution of this work is to propose a cavity‐based antenna with both dual‐polarization and bandpass filter characteristics. Proper cavity resonators and antenna based on the substrate integrated waveguide (SIW) technology are designed utilizing the low temperature co‐fired ceramics (LTCC) for demonstration. By properly arranging and coupling the cavities, a shaping of filter‐like response for the antenna gain and input return loss can be obtained. Measures for achieving a good isolation and a low cross‐polarization level have also been taken into account during the design procedure. A 4th‐order prototype working in the Ka‐band is designed and fabricated. Investigations show that the antenna presents a good isolation below ‐29 dB across the operating bandwidth, together with a cross‐polarization level lower than ‐25 dB at the center working frequency. The performance of the prototype has been verified in the measurement.

Managing interorganizational technology development: Project management practices for market‐ and science‐based partnerships

Firms are increasingly relying on collaborating with external partners to drive technology development. Many firms struggle with managing the inherently uncertain and ambiguous technology development process, especially with external actors involved, because they may not have or share the same project management practices concerning coordination and control activities. To address this gap, this study examines appropriate project management practices for market‐based and science‐based partnerships in three large technology‐intensive firms. Our results suggest that interorganizational technology development is problematic because firms lack sufficient partner understanding and struggle with aligning their project management practices with those of their partners. To address these problems, we identify project management practices of coordination and control to fit the contingencies of each type of partner collaboration. Our results provide implications for theory and managerial practices related to managing interorganizational technology development.

Design of a low‐power‐consumption a‐IGZO TFT‐based Vcom driver circuit with long‐term reliability

Abstract— An amorphous‐InGaZnO (a‐IGZO) thin‐film transistor (TFT)‐based Vcom driver circuit that has long‐term reliability and can be integrated with the pixel array on a panel has been designed. Owing to the Vcom inversion, the power consumed by the proposed driving scheme is 40% less than that consumed by the conventional line‐inversion method. The high mobility (>10 cm²/V‐sec) of the a‐IGZO TFTs allows the integration of devices with small channel widths (<750 μm) and thus keeps the overall device size small, which is important for displays with narrow bezels. The lifetime of the Vcom driver is improved by AC driving (by clocking the n‐th and (n + 1)‐th frame with 20 and 0 V, respectively) of the buffer TFTs.
