AbstractFlexibility and Interoperability have become important characteristics for organisations and their business processes. The need to control flexible business processes within an organisation’s boundaries and between organisations imposes major requirements on a company’s process control capabilities. Workflow Management Systems (WFMS) try to fulfil these requirements by offering respective product features. Evidence suggests that the achievement of flexible business processes and an inter-organisational process control is also influenced by implementation processes for Workflow Management Applications (WFMA). [A WFMA comprises the WFMS and "all WFMS specific data with regard to one or more business processes" [VER01]]. The impact of a WFMA implementation methodology on the fulfilment of these requirements is the research scope of the project. The thesis provides knowledge in the following areas: 1. Review of the relationship between workflow management and the claim for process flexibility respectively -interoperability. 2. Definition of a research-/evaluation framework for workflow projects. This framework is composed of all relevant research variables that have been identified for the thesis. 3. Empirical survey of relevant workflow-project objectives and their priority in the context of process flexibility and –interoperability. 4. Empirical survey of the objectives’ achievement. 5. Empirical survey of methodologies / activities that have been applied within workflow projects. 6. Derivation of the project methodologies’ effectiveness in terms of the impact that applied activities had on project objectives. 7. Evaluation of existing workflow life-cycle models in accordance with the research framework. 8. Identification of basic improvements for workflow implementation processes with respect to the achievement of flexible and interoperable business processes. The first part of the thesis argues the relevance of the subject. Afterwards research variables that constitute the evaluation framework for WFMA implementation processes are stepwise identified and defined. An empirical study then proves the variables’ effectiveness for the achievement of process flexibility and –interoperability within the WFMA implementation process. After this the framework is applied to evaluate chosen WFMA implementation methodologies. Identified weaknesses and effective methodological aspects are utilised to develop generic methodological improvements. These improvements are later validated by means of a case study and interviews with workflow experts.

Improving Construction Processes in Nigeria using the Last Planner SystemSuresh, Subashini; Ahiakwo, Ograbe, A. (2015-02-09)This thesis describes a research investigation into the implementation of the Last Planner System (LPS) in Nigeria, to improve construction processes within the Nigerian construction industry. LPS is known to be the most developed practical use of Lean Construction. It focuses on minimising the negative impacts of variability, uncertainties, buffers, making projects more predictable, creating reliable work plans and convalescing collaborative planning. However, the Nigerian construction industry is associated with a number of challenges which impair its performance. These challenges were grouped and classified into six major barriers: these include: supervision and quality control, fluctuation and variations, subcontractor involvement, resistance to change, cultural issues, and lengthy approvals. Consequently, a Design Science Research (DSR) approach is adopted to evaluate the effectiveness of implementing LPS in construction projects in Nigeria. In order to achieve this aim, an Action Research strategy is adopted and three case studies are reported; two of these cases describe how LPS was successfully implemented in construction projects within Nigeria. While the third case involved an investigation into the state of production plan reliability, of a successful project in Nigeria. These projects were selected based on non-probabilistic sampling from different geographical locations in Nigeria to represent different kinds of construction projects within the country. The first and second cases involved the implementation of LPS within the construction of a prototype student’s hostel and the construction a 4 Kilometre single carriageway road respectively. The third on the other hand involved the construction of a multipurpose hydro-power dam project; where comparisons were made between typical LPS projects and the project management techniques applied within the project. Data was collected through observation site activities, interviews, documentary analysis and questionnaire survey. The data generated was subsequently analysed by means of content analysis and evaluated in terms of its reliability, validity, representativeness, flexibility, rigour and reflexivity. In view of the LPS implementation within the two case studies, six barriers were identified and classified together with the six barriers associated with the Nigerian Construction industry. These barriers were linked, measured and ranked in averages of their degrees of occurrences. It was revealed that the major barriers were cultural issues and resistance to change, while the others include; lengthy approval, subcontractor’s involvement, poor supervision and quality, fluctuations and variations. Hence, a framework was developed to mitigate these barriers, when implementing LPS in construction projects in Nigeria. The main steps of the framework include: the need to identify purpose; the need to identify stakeholders impact; the need to obtain Sponsorship; the need to build a cross functional team; the need to create measurement indices; the need for training on Lean techniques and LPS; and finally the need to create a right working climate. Furthermore a focus group between construction practitioners was organised to test and evaluate the framework developed. It was revealed from the focus group that the framework has the potential to facilitate the implementation process as proposed.
Understanding the lived experiences of male victims of Intimate Partner Violence (IPV) in the disclosure process.Rooney, Rosemary (2016)Rationale: Service provisions for different forms of abuse experienced by men have increased in recent years. However, the voices and experiences of these victims remain significantly unrepresented both in the literature and the public domain. Disclosure of intimate partner violence (IPV) remain under-reported to the police and other personal and professional services aimed at male victims support and intervention. Whilst there is literature indicating the prevalence rates of IPV there is little describing the impact and consequences disclosing the experience of abuse has, particularly upon men. In order for healthcare professional and specialist service providers to provide adequate support and to avoid further trauma being experienced as part of the disclosure process there is a need for professionals to work in a reflexive manner and ensure any bias or personal values they may have and their knowledge of the subject does not hinder those seeking support and guidance. Method: The research follows the qualitative methodology of Interpretative Phenomenological Analysis (IPA). Participants were recruited through adverts placed with male support organisations. All participants were required to have made a disclosure within the past two years, however the abuse could have occurred at any time through the lifespan. Interviews were conducted face-to-face or via telephone following a semi-structured schedule. Data was gathered by conducting semi-structured interviews with five males who have experienced intimate partner violence. Results: The results identified five super-ordinate themes including a lack of support; a lack of awareness and stereotypes by personal and professional support; impact on self-identity, self-esteem and self-confidence; and shame, betrayal and isolation. Five sub-ordinate themes were identified and included difficulty recognising an abusive situation; difficulty finding support organisations if not computer literate and a lack of knowledge by frontline professionals. The majority of themes identified appeared to reflect a negative impact from disclosing to another person. A positive sub-ordinate theme was the support of female family members once they had processed the disclosure. Conclusions: Significant strides have been made in the awareness, understanding and provisions for female victims of abuse, the same for male victims’ remains lacking. The present study adds to existing literature by providing ideographic accounts from men who have disclosed intimate partner violence. Implications from the findings highlight a need for frontline staff to have a greater awareness of the needs and presentation of male abuse victims accessing services. The current findings indicate a need to provide earlier intervention, support and guidance for male abuse victims than those disclosed in this research. Despite the limited sample in this data, findings indicated a clear need to review current service provisions and training in the area of male victims of abuse.
