An Integrated Approach to Managing Business Process Risk Using Rich Organizational Models

Business processes represent the operational capabilities of an organization. In order to ensure process continuity, the effective management of risks becomes an area of key concern. In this paper we propose an approach for supporting risk identification with the use of higher-level organizational models. We provide some intuitive metrics for extracting measures of actor criticality and vulnerability from organizational models. This helps direct risk management to areas of critical importance within organization models. Additionally, the information can be used to assess alternative organizational structures in domains where risk mitigation is crucial. At the process level, these measures can be used to help direct improvements to the robustness and failsafe capabilities of critical or vulnerable processes. We believe our novel approach, will provide added benefits when used with other approaches to risk management during business process management, that do not reference the greater organizational context during risk assessment.

Citizen's charter driven service area improvement

A government organisations capability is reliant on its public service offerings in parallel with acceptable satisfaction level of its service recipients. Government organisations utilise a Citizens Charter in order to furnish the public with comprehensive details of their service offerings that defines how their overall organisational goals are achieved. Studies on the implementation of Citizens Charter in developing countries indicated that important social factors were not considered. Social factors can accelerate service delivery with the use of i* in goal-oriented modelling as it represent conditions expected from social actors and their social dependencies. By modelling role dependencies among actors carrying out services in a service area and applying vulnerability and criticality metrics, problem service areas were identified using the Citizens Charter as a source of these methodologies. Improvements in these problem service areas were based on vulnerability and criticality levels of their corresponding actors. Recommendations to address these service areas include monitoring of key performance indicators of actors and task delegation when necessary.

Integration of Agent-Oriented Conceptual Models and UML Activity Diagrams Using Effect Annotations

Agent-oriented conceptual modeling notations such as i* represents an interesting approach for modeling early phase requirements which includes organizational contexts, stakeholder intentions and rationale. On the other hand, Unified Modeling Language (UML) is suitable for later phases of requirement capture which usually focus on completeness, consistency, and automated verification of functional requirements for the new system. In this paper, we propose a methodology to facilitate and support the combined use of notation for modeling requirement engineering process in a synergistic fashion. For organizational modeling/early phase requirements capturing we use the i* modeling framework that describes the organizational relationships among various actors and their rationales. For late (functional) requirements specification, we rely on UML activity diagram.

Application of RFID technology to reduce overcrowding in hospital emergency departments

Australian hospital Emergency Departments (ED) are experiencing challenges due to overcrowding despite the government’s regular initiative of improved model of care. Australian Triage model of care within ED has not been able to prove reflective for ramification of the issues associated with overcrowding. This paper explores the opportunity for the use of Radio Frequency Identification (RFID) technology in hospital ED to reduce overcrowding. The Australian ED model of care with Triage scale and improved patient journey were studied. The best possible RFID integration was sought and evaluated against health care domain’s model of care. Potential indicators of suitability were ED length of stay, ED wait times. Ambulance diversions were studied and contrasted from the start of the patient journey to the end of the patient’s treatment cycle, to find opportunities for the implementation of RFID technology. Based on the results of the study, it is recommended that RFID implementation be tested in actual scenarios to realise the potential benefits.

Service Optimization Using Goal-Oriented Modelling in Judicial Domain

The purpose of this research paper is to identify and evaluate the obstacles of service delivery within in judicial domain and examine to what extent it can be improved. This report covers the evaluation of the current service delivery process within judicial domain and identifies the limitation with them. Besides that, it purposes an improved framework to optimize the services within judicial domain. Similarly, i* modelling frame work is used to identify the relationship between various key actors and the responsibilities between them to enhance the service delivery. Furthermore, it aims to implement the recommended model in the real service operation within judicial domain and evaluate the result. It then discussed about the possibilities of use of ICT within judicial domain to improve the service delivery. The impacts of poor resource allocation and the cost measurement of ac-tors are also discussed in this report. This study recommends conducting additional assessment to implementation of service optimization process within judicial domain. To conclude, this research paper proposes a way to organize services within judicial domain based on findings which assists judicial domain to provide effective and efficient service delivery to serve the community.

Service delivery innovation for hospital emergency management using rich organizational modelling

The purpose of this article is to identify and assess service delivery issues within a hospital emergency department and propose an improved model to address them. Possible solutions and options to these issues are explored to determine the one that best fits the context. In this article, we have analysed the emergency department’s organizational models through i* strategic dependency and rational modelling technique before proposing updated models that could potentially drive business process efficiencies. The results produced by the models, framework and improved patient journey in the emergency department were evaluated against the statistical data revealed from a reputed government organization related to health, to ensure that the key elements of the issues such as wait time, stay time/throughput, workload and human resource are resolved. The result of the evaluation was taken as a basis to determine the success of the project. Based on these results, the article recommends implementing the concept on actual scenario, where a positive result is achievable.

Enhancement of MD5 Algorithm for Secured Web Development

The research aims to develop an enhanced MD5 algorithm for the secure web development. The existing MD5 algorithm has many weaknesses that makes it vulnerable to different attacks such as brute force, rainbow table, birthday, dictionary etc. Despite these, the MD5 algorithm is still used in different applications, security protocols and even in the transmission and storage of digital data for verification, integrity and security of data by using checksum. The research focuses on mitigating the weaknesses inherent in the existing MD5 algorithm to secure web application and maintain data integrity and security. The research documents the proposal and implementation of an enhanced MD5 algorithm by varying its length and using a key to hash the data into its cipher form.

Risk Framework for Open Source Applications Using Agent Oriented Modelling

This paper aims to propose a novel risk framework utilizing agent oriented modelling in order to provide guidelines for the adoption of Open Source Software (OSS) solutions to an organization. Multiple studies have focused on user requirements and technical aspects when implementing OSS solutions. However, there is a lack of literature focusing on the social aspects of ‘why’ and ’how’ risks of OSS adoption can impact the overall organizational goals and the OSS ecosystem. Therefore, another focus area of this work is to bridge the gap between actors (goals, softgoals, task, and resources) and risk factors when adopting OSS in the organization by proposing new risk measurement and risk prioritization methods. This study is based on literature survey and a case study on OSS adoption in an organization. The research results show that the proposed risk measurement validates the current methods while providing deeper insights into the criticality and strong relationship between actors which in turn assists in proposing appropriate risk response strategies such as delegation of risk among these actors. The result implies that taking ecosystems into consideration is important for risk mitigation.
