Deriving organisational business process change factors using the hierarchical elicitation workshop
by Abdulrahman Alrabiah, Steve Drew
Abstract: The hierarchical elicitation workshop (HEW) is a new initiative designed and developed to address common shortcomings in business process change (BPC) initiatives in organisations, particularly those with tight temporal constraints imposed by exogenous bodies. This paper presents a systematic solution to deal with dramatic BPC under tight temporal constraints in large business and government organisations. In an empirical case study, the HEW is developed and trialled. Based on the Software Engineering Institutes Quality Attribute Workshop methodology, a step-by-step process was carried out to elicit and validate the required BPC factors. Engaging internal stakeholder teams to consider implications for BPC with respect to factors such as organisational objectives and strategies, governance, business process architecture and applications, a prioritised list of change actions was systematically elicited and then implemented. The HEW framework and process was successfully applied to elicit BPC factors in this case study, with an immediate and effective implementation of process change. This paper will be of particular interest to researchers of change management and business development.
Keywords: business process change; business models; change management; hierarchical elicitation workshop.
Miscegenation of scalable and DEP3K performance evaluation of nosql-cassandra for bigdata applications deployed in cloud
by Sangeeta Gupta, G. Narsimha
Abstract: A comprehensive performance and scalability evaluation of large web collection data is of significant importance in the modern world to yield high productivity and better outcomes. It is a fact that the huge data streams generated are difficult to analyse using the traditional tools and techniques. This data originates in the form of audio, video, and pdfs, and it is highly unstructured in nature. Traditional ways of storing and securing such unstructured data using relational databases such as mysql are inappropriate. Therefore, if tables and schema definitions are not a major concern, relational databases, such as mysql, may not be suitable to serve huge data volumes that exceed the single system storage capacity, termed as big data. An alternative approach is to use the emerging nosql databases. However, not all nosql databases provide full security. In this work, DEP3K-based interfusion of security and scalability is developed, where the large collection of web data collected through web crawlers is securely stored in the nosql database Cassandra. DEP3K is Double Encryption with Personal Passphrase based Private Key, a new methodology where the large collection of web data is securely stored and retrieved from Cassandra. Performance changes are brought into consideration before and after encrypting and decrypting the voluminous data, and improvement in efficiency (in milliseconds) is observed with the proposed model. Amazon Web Service (AWS) is used as a platform to host the required application service. Bitnami hosting services are used to install the required software as it supports cloud computing management. The monitoring is tracked via the Opscenter visual monitoring tool for Cassandra.
Keywords: nosql; big data; Cassandra; web crawler; mysql; private key; encryption; decryption.
SPCC: a security policy compliance checker plug-in for YAWL
by Khalid Alissa, Jason Reid, Ed Dawson
Abstract: YAWL provides a complete workflow system. It uses its own formal language to define the process model, which can then be translated by the YAWL engine into a working workflow system. The current structure of YAWL allows the process modeller to assign users/roles to perform tasks, but these assignments may not be in compliance with the organisation's authorisation policy. Violating the authorisation policy might lead to significant security risks. This paper introduces SPCC: an authorisation policy compliance checker for YAWL. SPCC is designed to help the process modeller to make sure the role-task assignments are in compliance with the organisation's authorisation policy. The paper describes the implementation of SPCC as a plug-in for YAWL.
Keywords: policy compliance; BPM; workflow; authorisation policies; compliance checker; YAWL.
Leadership and organisational conflict management: a case study of the Greek public sector.
by Irene Samanta, Athanasios Lamprakis
Abstract: Conflicts are an inherent component of any work environment and may contribute constructively to organisational life if they are approached in a constructive and cooperative way. The aim of this research survey is to bibliographically highlight the concepts of modern leadership types, the organisational conflict arising in management styles, and the links emerging from them. To achieve this objective, with the exception of the literature review, this survey focuses on examining the extent to which the transformational, transactional and laissez-faire leadership types impact conflict management, through a research case study in the field of Greek public procurement. For the research analysis, methods of the statistical package of SPSS 17.00, such as descriptive statistics, linear correlation, and multiple regression models, were used, along with all the necessary diagnostic statistical tests. The transformational and transactional leadership types were found to be positively correlated with the constructive conflict management approach (integrating, obliging and compromising conflict management styles) and negatively correlated with the non-constructive conflict management approach (dominating and avoiding conflict management styles), while the statistical outcomes found the overall impact of transformational leadership to be comparatively stronger. In contrast, laissez-faire leadership was found to be positively correlated with the non-constructive conflict management approach and negatively correlated with the constructive conflict management approach. The conclusions drawn constitute the culmination of a thorough study of the phenomenon of the organisational conflicts in a Greek public organisation that has high working standards, creating a useful empirical precedent for further investigation of the conflict management approach in the Greek public organisational reality.
Keywords: transformational leadership; transactional leadership; laissez-faire leadership; organisational conflict management styles; constructive and non-constructive conflict management approaches.
