Knowledge dependencies in fuzzy information systems evaluation

Experience and research within the field of Information Systems Evaluation (ISE), has traditionally centered on providing tools and techniques for investment justification and appraisal, based upon explicit knowledge which encodes financial and other direct situational factors (such as accounting, costing and risk metrics). However, such approaches tend not to include additional causal interdependencies that are based upon tacit knowledge and are inherent within such a decision-making task. The authors show the results of applying a cognitive mapping approach, in the guise of a Fuzzy Cognitive Mapping (FCM) simulation, i.e. Fuzzy Information Systems Evaluation (F-ISE), in order to highlight the usefulness of applying such a technique. The authors highlight those contingent and necessary knowledge dependencies, in an exploratory sense, which relate to the investment appraisal decision-making task, in terms of the interplay between tacit and explicit knowledge, in this regard

A SECI-Based Knowledge Conversion Model of Business Process Capture

Security questions are one of the mechanisms used to recover passwords. Strong answers to security questions (i.e. high entropy) are hard for attackers to guess or obtain using social engineering techniques (e.g. monitoring of social networking profiles), but at the same time are difficult to remember. Instead, weak answers to security questions (i.e. low entropy) are easy to remember, which makes them more vulnerable to cyber-attacks. Convenience leads users to use the same answers to security questions on multiple accounts, which exposes these accounts to numerous cyber-threats. Hence, current security questions implementations rarely achieve the required security and memorability requirements. This research study is the first step in the development of a model which investigates the determinants that influence users’ behavioural intentions through motivation to select strong and memorable answers to security questions. This research also provides design recommendations for novel security questions mechanisms

The Role of User Guidance in the Industrial Adoption of MDE Approach

Model-Driven Engineering (MDE) has emerged as an actively researched and established approach for next generation control application development. Technology transfer to the industry is a topical research problem. Since most professional factory process control engineers do not have computer science backgrounds, there is an urgent need for studies of the role of user guidance in the professional learning, and thus, of industrial adoption of MDE approaches. In this study professionals were invited to a hands-on assessment of the AUKOTON MDE approach for factory process control engineering. Qualitative empirical material was collected and analyzed to identify the role of user guidance in the context of other factors impacting industrial adoption. Challenges in adoption that could be solved by user guidance were identified with the theory of organizational knowledge creation (SECI) model

Supporting Customized Design Thinking Using a Metamodel-based Approach

Traditional design methods, based on analytical rationale, often cannot address upcoming challenges e.g., related to the digital business transformation in volatile environments. Analytical rationale assumes a particular result and provides the methods and tools for achieving it. Nowadays, however, the result of a business transformation is often not precisely known nor the ways and means to achieve it. As a result, methods and tools are required that foster creativity while allowing customization to specific requirements or stakeholder needs. This paper proposes customized design thinking processes, realized with a conceptual modelling approach. The approach supports creativity in transformative business design. It shows how numerous design thinking tools can be integrated into a single conceptual modelling approach - supported by a modelling platform. The platform facilitates efficient and flexible design of novel business solutions. The created models moreover serve as a formalized knowledge base that enables knowledge processing and reuse

A conceptual model of pair programming knowledge-based sharing for improving programming skills

One of eXtream Programming practices is Pair Programming (PP) (the pair consists of a driver and a navigator), which is used for promoting knowledge sharing among students. This practice encourages students to think creatively of programming solutions, and simplify learning, especially for difficult course such as Java. By applying PP, students are enforced to improve their social skills as they communicate with each others. Despite the numerous benefits of PP (discussed by previous studies), statistics show lack of demonstrating the extent at which the knowledge sharing, communication and transfer between the driver and the navigator can improve the code quality. Therefore this study aims propose a conceptual model of a PP knowledge-based sharing for improving programming skills. In order to achieve the stated objective, PP laboratory assignments were conducted and compared to evaluate the impact of PP on code quality with and without adopting the conceptual model. The conceptual model was validated by analyzing the collected data from the participants of PP laboratory assignment using Partial Least Square form of Structural Equation Modeling (PLS-SEM). The findings of the study show that socialization, combination, and internalization are the determinant factors for achieving better code quality in PP environment. The findings of this study would be benefited to academic environment especially the agile programmers in the pair programming domain

Lean Thinking For Lead-Time Reduction And Efficient Knowledge Creation In Product Development

There are many distinct differences between manufacturing process and Product Development (PD) process, so lean tools have to be customized to deliver results in the later domain. The main focus of this dissertation is to extend them to manage and improve the PD process in order to develop the product faster while improving or at least maintaining the level of performance and quality. For aforesaid purpose, value stream mapping (VSM) method is used to explore the wastes, inefficiencies, non-valued added steps in a single, definable process out of complete PD process. Besides numerous intangible benefits, VSM framework will help the development team to reduce the lead-time by over 50%. Next, a set of ten lean tools and methods is proposed in order to support and improve efficiency of the knowledge creation (KC) process. The approach establishes a KC framework in PD environment, and systematically demonstrates how these lean tools and methods conceptually fit into and play a significant role in enhancing the performance of KC process. Following this, each of them is analysed and appropriately positioned in a SECI (socialization-externalization-combination-internalization) mode depending on the best fit. Quick and correct KC at the right time aids in further improving the development lead-time and product quality. Such successful innovation is often associated with adoption and execution of all SECI modes within any PD phase. This dissertation attempts to argue with this general notion and to distinguish different PD phases\u27 affinity corresponding to distinct SECI mode. In this regard, an extended Fuzzy Analytic Hierarchy Process (EFAHP) approach to determine the ranking in which any PD phase is influenced from SECI modes is proposed. In the EFAHP approach, the complex problem of KC is first itemized into a simple hierarchical structure for pairwise comparisons. Next, a triangular fuzzy number concept is applied to capture the inherent vagueness in linguistic terms of a decision-maker. This dissertation recommends mapping the triangular fuzzy numbers (TFNs) with normal distributions about X-axis when the pessimistic value of one TFN is less than the optimistic value of other TFN (t23 ≤ t11). This allows us to develop a mathematical formulation to estimate the degree of possibility of two criteria as opposed to zero resulted by the use of the current technique in the literature. In order to demonstrate the applicability and usefulness of the proposed EFAHP in ranking the SECI modes, an empirical study of development phase is considered. After stringent analysis, we found that the combination mode was the mode that highly influenced the development phase

Finally the information system was developed based on the proposed model. The user acceptance test proofs that the proposed model and developed system can successfully implemented and help post graduate students to overcome their difficulties

Knowledge Management for Informally Structured Domains: Challenges and Proposals

Eliciting requirements of products or solutions in informally structured domains is a highly creative and complex activity due to the inherent characteristics of these domains, such as the great quantities of tacit knowledge used by domain specialists, the dynamic interaction between domain specialists and their environment in order to solve problems, the necessity of these solutions of products to be developed by teams of specialists and the asymmetry of knowledge between domain specialists and requirements engineers. The knowledge management discipline promotes an integrated approach in order to face these challenges; therefore, a strategy for addressing requirements elicitation that incorporates techniques and methods of this discipline has been proposed as a serious approach to deal with those challenges. The valuable results of the application of the strategy in real cases prove empirical insights about its utility
