Incremental Consistency Checking in Delta-oriented UML-Models for Automation Systems

Automation systems exist in many variants and may evolve over time in order to deal with different environment contexts or to fulfill changing customer requirements. This induces an increased complexity during design-time as well as tedious maintenance efforts. We already proposed a multi-perspective modeling approach to improve the development of such systems. It operates on different levels of abstraction by using well-known UML-models with activity, composite structure and state chart models. Each perspective was enriched with delta modeling to manage variability and evolution. As an extension, we now focus on the development of an efficient consistency checking method at several levels to ensure valid variants of the automation system. Consistency checking must be provided for each perspective in isolation, in-between the perspectives as well as after the application of a delta.Comment: In Proceedings FMSPLE 2016, arXiv:1603.0857

A strategic approach to making sense of the “wicked” problem of ERM

Purpose – The purpose of this paper is to provide an approach to viewing the “wicked” problem of electronic records management (ERM), using the Cynefin framework, a sense-making tool. It re-conceptualises the ERM challenge by understanding the nature of the people issues. This supports decision making about the most appropriate tactics to adopt to effect positive change. Design/methodology/approach – Cynefin was used to synthesise qualitative data from an empirical research project that investigated strategies and tactics for improving ERM. Findings – ERM may be thought of as a dynamic, complex challenge but, viewed through the Cynefin framework, many issues are not complex; they are simple or complicated and can be addressed using best or good practice. The truly complex issues need a different approach, described as emergent practice. Cynefin provides a different lens through which to view, make sense of and re-perceive the ERM challenge and offers a strategic approach to accelerating change. Research limitations/implications – Since Cynefin has been applied to one data set, the findings are transferrable not generalisable. They, and/or the approach, can be used to further test the propositions. Practical implications – The resultant ERM framework provides a practical example for information and records managers to exploit or use as a starting point to explore the situation in particular organisational contexts. It could also be used in other practical, teaching and/or research-related records contexts. Originality/value – This paper provides a new strategic approach to addressing the wicked problem of ERM, which is applicable for any organisational context

Boundary Objects and their Use in Agile Systems Engineering

Agile methods are increasingly introduced in automotive companies in the attempt to become more efficient and flexible in the system development. The adoption of agile practices influences communication between stakeholders, but also makes companies rethink the management of artifacts and documentation like requirements, safety compliance documents, and architecture models. Practitioners aim to reduce irrelevant documentation, but face a lack of guidance to determine what artifacts are needed and how they should be managed. This paper presents artifacts, challenges, guidelines, and practices for the continuous management of systems engineering artifacts in automotive based on a theoretical and empirical understanding of the topic. In collaboration with 53 practitioners from six automotive companies, we conducted a design-science study involving interviews, a questionnaire, focus groups, and practical data analysis of a systems engineering tool. The guidelines suggest the distinction between artifacts that are shared among different actors in a company (boundary objects) and those that are used within a team (locally relevant artifacts). We propose an analysis approach to identify boundary objects and three practices to manage systems engineering artifacts in industry

Customer Enquiry Management in a Global Competitive Context: A Comparative Multi-Case Study Analysis

Business-to-Business (B2B) relationships, such as between a manufacturer and a customer, are increasingly important during the Customer Enquiry Management (CEM) process, particularly so for non-Make-To-Stock (non-MTS) companies operating in industrial markets. Few empirical studies have explored the CEM practices adopted by firms in practice. A study of the Italian capital goods sector by Zorzini et al. (2007) is a recent exception. Moreover, most studies have approached CEM from a cross-department integrated perspective but in the digital economy, and with globalization, outsourcing and extended supply chains, CEM needs to be approached from a broader supply chain-oriented perspective, incorporating B2B exchanges. This paper builds on the study by Zorzini et al. (2007) by conducting multi-case study research with seven UK-based companies in the capital goods sector, including three sales and support companies with offshore manufacturing. By adopting a cross-national research perspective, it assesses whether the proposed theory applies to other capital goods firms outside Italy. By also adopting a supply chain perspective of CEM it investigates current industry practice in B2B markets and explores whether cross-functional coordination and formalization issues can be extended into a global context. Evidence from the UK generally supports prior theory, confirming links between high levels of coordination, formalization of the CEM process and improved performance. Some refinements are proposed, for example, in order to make the theory suitable for a global context. The characteristics of a supply chain are important factors that affect CEM. This research has managerial implications for improving the CEM process in non-Make-To-Stock (non-MTS) capital goods companies from both an intra and an inter-organisational (B2B) perspective. Coordination with partners along the supply chain is needed at the enquiry stage and constraints linked to global customers should be considered when structuring the

A traumatised and traumatising system: Professionals' experiences in meeting the mental health needs of young people in the care and youth justice systems in Ireland

It is well recognised that children and young people in the care and youth justice systems typically present with significant and diverse mental health needs. Much has been written about this challenging area of professional practice but the focus has been primarily on the young people themselves rather than professionals' experiences of working in this challenging context. In this study, focus groups and individual interviews were conducted with 26 professionals working in the care and youth justice services in Ireland, representing a range of disciplines, to capture professionals' perspectives of working in this field. A thematic analysis was conducted on the transcribed data. Professionals described frustration and helplessness in the face of what they perceived as inadequate system responses and poor interagency working. Their experiences are conceptualised here as reflecting a traumatised and traumatising system. The implications for practice emphasise the need for staff support through training, collaboration between agencies, and addressing vicarious traumatisation

Promises, pitfalls and shortfalls of the guaranteed maximum price approach: A comparative case study

The relative merits of the guaranteed maximum price (GMP) mechanism as a contractual incentive in construction have been much contested. This question was investigated using a comparative case study of two building projects in Hong Kong. Data was collected through semi-structured interviews, review of project documentation and communications, and passive observation of project meetings. The findings suggest that the GMP mechanism has low incentive intensity from an instrumental rationality perspective and high incentive intensity from a value-expressive perspective. Further analysis of the findings leads to two main conclusions about the potential value of the GMP mechanism to a client: (a) it can provide some flexibility in responding to short-term market changes and other idiosyncratic factors and (b) it can be a useful instrument for project work group integration. Based on current approaches to GMP projects in Hong Kong, the ultimate compensation for the additional risk transfer to the contractor should come from the applied mark up or fee rather than any expectation or possibility of financial reward for net cost savings

Systems practice at the United Kingdom's Open University

This chapter relates the emerging focus on systems practice within the Systems Discipline at the Open University. Recent innovations have occurred in the changing environment of the University (Lane 1999), the higher education sector (Ison 1999) and the systems community more generally (Maiteny and Ison 2000)

Clinical governance, education and learning to manage health information

Purpose – This paper aims to suggest that the concept of clinical governance goes beyond a bureaucratic accountability structure and can be viewed as a negotiated balance between imperfectly aligned and sometimes conflicting goals within a complex adaptive system. On this view, the information system cannot be separated conceptually from the system of governance it supports or the people whose work it facilitates or hinders. Design/methodology/approach – The study, located within the English National Health Service (NHS) between 1999 and 2005, is case study based using a multi method approach to data collection within two primary care organisations (PCOs). The research strategy is conducted within a social constructionist ontological perspective. Findings – The findings reflect the following broad-based themes: mutual adjustment of a plurality of stakeholder perceptions, preferences and priorities; the development of information and communication systems, empowered by informatics; an emphasis on education and training to build capacity and capability. Research limitations/implications – Limitations of case study methodology include a tendency to provide selected accounts. These are potentially biased and risk trivialising findings. Rooted in specific context, their generalisability to other contexts is limited by the extent to which contexts are similar. Reasonable attempts were made to minimise any bias. The diversity of data collection methods used in the study was an attempt to counterbalance the limitations highlighted in one method by strength from alternative techniques. Practical implications – The paper makes recommendations in two key governance areas: education and learning to manage health information. In practice, the lessons learned provide opportunities to inform future approaches to health informatics educational programmes. Originality/value – With regard to topicality, it is suggested that many of the developmental issues highlighted during the establishment of quality improvement programmes within primary care organisations (PCGs/PCTs) are relevant in the light of current NHS reforms and move towards commissioning consortia
