Conference Object Information System Process Improvement: a Managerial Perspective and Proposal of a General Framework(2006) Mishra,A.; Mishra,D.; Akman,I.System process improvement is a continuous strategy in organizations for reducing overall cost, shortening cycle times, and improve quality and user satisfaction. There are various models like Capability Maturity Model (CMM), ISO, etc. available to measure process improvement. However management role is vital for effective process improvement implementation strategy. This paper briefly presents an assessment of all the factors which, if taken care by the management effectively, can ensure success in information system process improvement and proposes a general 2-stage framework for process improvement. The framework presents stochastic simulation model which is tailored to the dynamics of software projects, and which takes management plan and individual processes as input to show how simulation can be used to achieve effective project management.Conference Object Citation - Scopus: 2A Cognitive Evaluation for Meetings in Software Development Process(Springer Verlag, 2009) Misra,S.; Akman,I.Software development includes number of different type of meetings in the whole development process. The cognitive activities also play an important role in decision making activities in these meetings since they are carried out by human being. In this paper, we evaluated the relevance of meetings in different phases of the software development process with reference to cognitive aspects. © 2009 Springer Berlin Heidelberg.Article Citation - WoS: 22Citation - Scopus: 33An Ontology-Based Security Risk Management Model for Information Systems(Springer Heidelberg, 2020) Arogundade, Oluwasefunmi T.; Abayomi-Alli, Adebayo; Misra, SanjaySecurity risk management is a knowledge-intensive procedure that requires monitoring and capturing relevant information that can assist in making the right decision by managers. In this paper, a semantically enhanced model for security management during the information system lifetime is proposed. The model supports the continuous collection of identified threat behaviours from the intrusion detection system, filtering and analysis of the threats within a time snapshot and re-appraiser of IS security countermeasures which involves the security administrator (S-Admin), managers, IS and security management system as stakeholders. The probe agent categorizes the security threats identified by the IDS using the developed ontology-driven knowledge base, while the likelihood of threats occurring in real time was obtained using long-term frequency probability. The case-based reasoning paradigm is employed for the security solution reasoning of identified threat risk. The suggested security solutions are based on CASE base built on existing threat ontology. The re-appraiser is based on the success likelihood of potential ongoing threats. The system facilitates management decision with regard to security control selection so that they can have a maximum Return on Security Investment. The proposed Collect-Probe-Analyse-Reason-Reappraise model is illustrated using an e-banking system.Article Citation - WoS: 18Citation - Scopus: 24University Students' Heuristic Usability Inspection of the National Library of Turkey Website(Emerald Group Publishing Ltd, 2018) Inal, YavuzPurpose - The purpose of this paper is to evaluate the usability of the National Library of Turkey website developed for all citizens in the country to retrieve information available in a wide range of areas. Design/methodology/approach - The evaluation performed by 57 undergraduate university students involved the identification and analysis of usability problems in the selected website. The assessment process was mainly based on Nielsen's Heuristics. The data obtained in the evaluation process were enriched using the System Usability Scale (SUS) and the Net Promoter Score (NPS) to conduct a more detailed analysis. Findings - The participants identified many usability problems concerning the evaluated website and considered it as having low usability characteristics. The most violated heuristic item was found to be "consistency and standards" whereas the least violated heuristic item was "match between system and the real world." The total number of the usability problems in heuristic evaluation correlated significantly and negatively with the SUS and the NPS results indicating that the more participants identified usability problems, the less they considered the website as usable and recommendable. Research limitations/implications - The participants were not usability experts, however they were selected from among the students who received the Human Computer Interaction course to ensure that they had sufficient information and experience concerning the evaluation of a website with heuristics. Besides, the study was limited to a small number of university students. The implication is that results of this study have potential to guide libraries, which plan to adapt themselves to the digital world by delivering web services, by addressing critical points influencing users' points of views toward library websites and their usability evaluation result. Practical implications - Depending on the changes in user habits regarding the retrieval of information, libraries have made considerable investments in web technologies to meet their users' demands, and recently, digital libraries have begun to take over physical libraries. Users always need to perform tasks efficiently, effectively and satisfactorily when using websites. As one of the most crucial sources of digital materials, library websites are expected to have usable characteristics that satisfactorily meet user requirements. Therefore, the practical implication is that the findings of the study will guide designers, developers and practitioners in the development of library websites. Originality/value - In the context of usability evaluation of digital libraries, this is the first study to analyze effects of usability problems identified by users during the heuristic inspection on their overall evaluation score and willingness to recommend the website to their friends or colleagues.
