Exploration of the relationship between tacit knowledge and software system test complexity

This research has explored the relationship between system test complexity and tacit knowledge. It is proposed as part of this thesis, that the process of system testing (comprising of test planning, test development, test execution, test fault analysis, test measurement, and case management), is directly affected by both complexity associated with the system under test, and also by other sources of complexity, independent of the system under test, but related to the wider process of system testing. While a certain amount of knowledge related to the system under test is inherent, tacit in nature, and therefore difficult to make explicit, it has been found that a significant amount of knowledge relating to these other sources of complexity, can indeed be made explicit. While the importance of explicit knowledge has been reinforced by this research, there has been a lack of evidence to suggest that the availability of tacit knowledge to a test team is of any less importance to the process of system testing, when operating in a traditional software development environment. The sentiment was commonly expressed by participants, that even though a considerable amount of explicit knowledge relating to the system is freely available, that a good deal of knowledge relating to the system under test, which is demanded for effective system testing, is actually tacit in nature (approximately 60% of participants operating in a traditional development environment, and 60% of participants operating in an agile development environment, expressed similar sentiments). To cater for the availability of tacit knowledge relating to the system under test, and indeed, both explicit and tacit knowledge required by system testing in general, an appropriate knowledge management structure needs to be in place. This would appear to be required, irrespective of the employed development methodology.

Enabling effective operational decision making on a Combined Heat and Power System using the 5C architecture

The use of Cyber Physical Systems (CPS) to optimise industrial energy systems is an approach which has the potential to positively impact on manufacturing sector energy efficiency. The need to obtain data to facilitate the implementation of a CPS in an industrial energy system is however a complex task which is often implemented in a non-standardised way. The use of the 5C CPS architecture has the potential to standardise this approach. This paper describes a case study where data from a Combined Heat and Power (CHP) system located in a large manufacturing company was fused with grid electricity and gas models as well as a maintenance cost model using the 5C architecture with a view to making effective decisions on its cost efficient operation. A control change implemented based on the cognitive analysis enabled via the 5C architecture implementation has resulted in energy cost savings of over €7400 over a four-month period, with energy cost savings of over €150,000 projected once the 5C architecture is extended into the production environment.

Victims' rights in Ireland: influences, illusions and impacts

Following international trends victims of crime in Ireland have increasingly become a source of political, policy and to a lesser extent academic concern. Although it is assumed that the Irish victims’ rights movement is having a profound impact on the criminal justice system there are very few studies addressing this assumption or the genesis of the Irish movement. At the time a victims’ rights movement was established in Ireland there were movements already established in the U.S. and Britain. To determine which model Ireland followed, if any, in establishing its movement a comparative analysis of the emergence of the victims’ rights movements in these three common law jurisdictions was undertaken. This research examines possible victim policy transfer to test the transfer route perception that the victims’ movement began in the U.S., was transferred into Britain and then onto Ireland. At the same time that the victims’ rights movements were emerging in the U.S., Britain and Ireland, and asserting pressure on their national governments for beneficial changes for victims of crime, international organisations such as the U.N. and Council of Europe were being pressured by victims’ rights groups into introducing victim centered instruments of guidance and best practice for member states. Eventually the E.U. became involved and enacted a binding instrument in 2001. These victim centered instruments provide legal and service provision rights to Irish victims of crime, but they do not generate much academic interest. This research, in addition to providing a detailed account of the victim centered instruments, analyses the jurisprudence of the European Court of Human Rights, and identifies and analyses the primary victim centered statutory modifications and case law in Ireland over the past three decades. Lastly, the current law and practices in Ireland are evaluated against Ireland’s obligations under international and E.U. law.
