Purpose – The deformation of a large fuselage panel is unavoidable due to its weak-stiffness and low-rigidity. Sometimes, the assembly accuracy of the panel is out of tolerance. The purpose of this paper is to propose a method to predict and correct the assembly deformation of a large fuselage panel during digital assembly by using a finite element (FE) analysis and partial least squares regression (PLSR) method. Design/methodology/approach – A FE model is proposed to optimize the layout of load-transmitting devices to reduce panel deformation after the process of hoisting and supporting. Furthermore, another FE model is established to investigate the deformation behavior of the panel. By orthogonal simulations, the position error data of measurement points representing the precision of the panel are obtained. Then, a mathematical model of the relationship between the position errors of measurement points on the panel and the displacements of numerical control positioners is developed based on the PLSR method. Findings – The case study shows that the model has a high level of computing accuracy and that the proposed method is an efficient way to correct the panel deformation in digital assembly. Originality/value – The results of this study will enhance the understanding of the deformation behavior of a panel in aircraft digital assembly and help to improve the assembly precision systematically and efficiently.

PurposeThe purpose of this study is to focus on organisation’s cybersecurity strategy and propose a high-level programme for cybersecurity education and awareness to be used when targeting small- and medium-sized enterprises/businesses (SMEs/SMBs) at a city-level. An essential component of an organisation’s cybersecurity strategy is building awareness and education of online threats and how to protect corporate data and services. This programme is based on existing research and provides a unique insight into an ongoing city-based project with similar aims.Design/methodology/approachTo structure this work, a scoping review was conducted of the literature in cybersecurity education and awareness, particularly for SMEs/SMBs. This theoretical analysis was complemented using a case study and reflecting on an ongoing, innovative programme that seeks to work with these businesses to significantly enhance their security posture. From these analyses, best practices and important lessons/recommendations to produce a high-level programme for cybersecurity education and awareness were recommended.FindingsWhile the literature can be informative at guiding education and awareness programmes, it may not always reach real-world programmes. However, existing programmes, such as the one explored in this study, have great potential, but there can be room for improvement. Knowledge from each of these areas can, and should, be combined to the benefit of the academic and practitioner communities.Originality/valueThe study contributes to current research through the outline of a high-level programme for cybersecurity education and awareness targeting SMEs/SMBs. Through this research, literature in this space was examined and insights into the advances and challenges faced by an on-going programme were presented. These analyses allow us to craft a proposal for a core programme that can assist in improving the security education, awareness and training that targets SMEs/SMBs.

Purpose It is widely recognized that large-scale public–private partnership (PPP) projects require an effective coordination mechanism among various stakeholders throughout the project life cycle. The purpose of this paper is to provide an insight into how this may be achieved through the leading small group (LSG), which is a distinctive informal Chinese institution for coordination among various public agencies. Design/methodology/approach An in-depth case study using secondary data and five in-depth interviews with two staff members from the developer and three government officials involved is used to probe into how the LSG functions during the various development phases of the Yangzhou Teda Waste-to-Energy project. Findings The main finding is that, conditional on its capacity, the LSG coordinated various public agencies to promote fast project implementation and ensure its smooth operation by making high-level decisions, facilitating quick permits and approvals, and mitigating the risks. However, formalization and participation from other stakeholders are needed to ensure good governance. Research limitations/implications Because it is an exploratory case study, the findings cannot be readily generalized. Further research can be done to compare the performance of LSGs in different Chinese cities and PPP projects. Practical implications It is supposed that this paper can provide implications of designing effective coordination mechanisms for managing large-scale PPP projects. Originality/value This paper provides an account of the LSG as a distinctive Chinese coordination mechanism that has been rarely studied.

Purpose The purpose of this paper is to analyze change process perceptions of public service employees and document how change readiness belief salience fluctuates and evolves throughout the implementation of a major organizational restructuring effort. Design/methodology/approach This research is a longitudinal multiple-case study of a major transformation initiative in a large North American public recreation organization. Over the course of 15 months, the authors conducted four rounds of personal interviews with 19 participants (65 interviews in total, each lasting 25–45 min). Additionally, the authors analyzed internal e-mail correspondence, memos, and meeting agendas, as well as external stakeholder communication. Finally, the primary researcher spent a significant amount of time collecting field notes while shadowing high-level managers and employees and attending meetings. Findings Overall, the authors documented a clear hierarchy of change readiness dimensions. The relative strength and temporal persistence of these dimensions can be traced back to various public organizing particularities. Moreover, the authors found that an initial focus on some readiness dimensions facilitated subsequent sensemaking processes whereas others hindered such engagement with the change project. Research limitations/implications This research is the first to empirically document temporal fluidity of change readiness dimensions and salience. Moreover, it offers a rare in-depth look at a changing public service organization. Practical implications This research helps change agents in developing tailored change messages and to better understand potential sources of frustration and resistance to change efforts. Originality/value No similar efforts exist to document the underlying dynamism of evolving change readiness perceptions.

Subject area Diplomatic and consular policies; legal aspects of international relations and Asia regional scenario. Study level/applicability Undergraduate. Case overview In April 2012, high-level officials from China and the USA were about to meet in Beijing in the framework of the bilateral Strategic and Economic Dialogue, organized on a yearly basis. The event was always delicate, due to the ambiguous relationship existing between the two countries, which were at the same time rivals and dependent on one another. That time, the tension previous to the meeting increased significantly: a Chinese human rights activist had just sought and obtained diplomatic protection in the US Embassy in Beijing, thus creating an embarrassing situation for both States' foreign departments […] How could they possibly solve this contentious issue without affecting their already sensitive relationship? Expected learning outcomes Analytical: to be aware of the political nature of the current Chinese Government; to realize the concrete and practical implications of an Embassy's special status; to balance two contradictory objectives, in a specific situation where none of them can be fully discarded; to contrast and try to combine long-term goals (in this case, to maintain a functioning relationship between two main world powers) with short-term objectives (in this case, how to deal with a Chinese activist that required protection against his own country's security forces); to find a modus vivendi (conciliation) between values and interests; to get convinced that certain kinds of negotiations cannot be conceived through a “win or lose” approach: in this case, the only way out must be respectful of the two parties' core interests; and to take into account that image preservation (“face-saving”) must be included within any country's objectives in any situation involving diplomatic means. Conceptual: the purpose is to familiarize the students with specific concepts, such as: best alternative to a negotiated agreement (BATNA), which is to be mentioned as part of the discussion (it is not included in the case study itself); interdependence; (purported) Group of Two; asylum and refuge; Immunity; and sending state/receiving state.

Purpose The purpose of this paper is to show how collaborative information technology (IT) tools and a crowdsourcing model can be leveraged for the purpose of strategic planning. To achieve this objective, a formal method of open strategic planning (OSP) is proposed. Design/methodology/approach Based on a review of the literature a set of activities, stakeholders, and governing rules are identified in the form of an OSP method. The proposed planning method is implemented in a case study of strategic planning in an Australian university. Observations by the research team, and archival records were used to ascertain the relevance of the used method. Findings A method for OSP is presented and assessed. The method contains four phases: pre-planning, idea submission, idea refinement, and plan development. These phases cover the activities required from conceptualization to preparing and publishing the strategic plan. The findings clarify how the principles of OSP helped the organization to include more stakeholders and provided the opportunity to make the planning process transparent through use of a collaborative IT tool. Practical implications The study provides managers and planning consultants with detailed guidelines to implement the concept of open strategy. Originality/value This study is among the few to propose a method for OSP based on empirical research. The study also shows how collaborative IT tools can be used for high-level organizational tasks such as strategic planning.

PurposeTo elaborate a methodology enabling organizations to define their strategic processes among other processes.Design/methodology/approachA case study approach has been chosen due to the nature of this research. Case study research method is qualitative method but it can be positivist. The mix of techniques is appropriate and some degree of quantification is necessary. Three high‐level steps are designed and these steps are developed in the managerial holding companies (research case study).FindingsBecause of limitations on budget and time, organizations are able to define the processes which are critical to achieve organizations' goals. This methodology has a holistic view in organizations by using balanced scorecard framework.Research limitations/implicationsThis research is based on a single case. Generalization based on this case should be interpreted cautiously and a limitation of the case study should be kept in mind. Furthermore, the strategy of the research case is a competitive strategy and the strategic processes are chosen according to this strategy. They may be changed based on other strategies. In interpreting the result, these limitations should be kept in mind.Originality/valueDefining the strategic processes helps organizations to use their resources based on their objectives. This paper presents a methodology that improves the ability of organizations in managing and directing their resources efficiently.

Purpose The existing literature suggests that multinational corporations (MNCs) divest subsidiary units whenever they cease to enjoy the advantages of ownership, location or internalization. However, not all MNCs divest under these conditions. This paper aims to explore the factors that contributed to the survival of a particular subsidiary and prevented it from being divested. Design/methodology/approach The analysis focuses on an individual subsidiary of a large foreign MNC in the electronics industry, which divested other subsidiaries from Portugal. Data were collected using semi-structured interviews. Findings The subsidiary’s diverse customer base, specificity and high level of efficiency, the local advantages, the existing governmental agreements and the parent MNC’s previous unsuccessful relocation experiences seem to have contributed to the survival of the subsidiary. Research limitations/implications Although the results of the case study are not generalizable to the entire population of firms, the featured case study is a rare survival success story in the Portuguese electronics industry. Practical implications The proposed framework may offer public authorities measures to create conditions to encourage firms to retain their investment in a particular site. For corporate strategists, new perspectives on subsidiary survival are provided. Originality/value This paper is one of the few qualitative studies in the field of subsidiary survival. The results offer an integrative framework on which factors contribute to the survival of a subsidiary located on a comparatively unfavorable labor cost location and support the role of the organizational learning and of previous failed relocation experiences and relocation barriers when a parent MNC decides whether to retain a unit.

Purpose – In the late 2000s, the Ultimate Fighting Championships (UFC) emerged to become the dominant mixed martial arts (MMA) organisation, bringing the sport to mainstream acceptance. The purpose of this paper is to draw on theories of co-evolution and positive feedbacks to provide insights into how the UFC has assumed this dominant position. Design/methodology/approach – A single historical case study is compiled drawing on data from a number of sources, including the UFC, US State Athletic Commissions, MMA web sites and prior UFC-related academic literature. Findings – A number of significant growth dynamics are identified, including interconnections between the increase in free-to-air events and the generation of new UFC fans and revenues; the increased financial rewards to successful fighters that allows them to improve the quality of their training and the improved quality of UFC content; and the accumulation of a critical mass of high-level fighters that increases the reputation of the UFC and the increased attraction of new fighters to the organisation. Research limitations/implications – Further in depth studies are necessary to substantiate and quantify the interconnections identified in this paper. Practical implications – The paper provides insights for other non-mainstream sports organisations that are attempting to grow their participation and viewership. Originality/value – The emergence of new sports and sports organisations such as the UFC with global appeal and significant commercial returns is infrequent. This study contributes to the need for understanding of how new sports enter the mainstream and the role that governing organisations such as the UFC play in achieving this transition.

Purpose The purpose of this paper is to identify factors influencing implementation of control charts on key performance indicators (KPIs). Design/methodology/approach Factors driving organizational change described in literature are analyzed inspired by the affinity-interrelationship method. A holistic multiple-case design is used to conduct six workshops to affect the usage of control charts on KPIs at a global company in the automotive industry. The theoretical factors are compared with the result from the case study. Findings The important factors for implementation success differ to some extent between the theoretical and empirical studies. High-level commitment and a clear definition of the goal of change could be most important when creating a motivation for change. Thereafter, having a dedicated change agent, choosing an important KPI and being able to describe the gain in financial terms becomes more important. Practical implications By using control charts on KPIs, the organization in the case study has become more proactive, addressing the right issues upstream in the process, in the right way, cross-functionally. Originality/value Factors affecting the implementation of already available solutions in the industry are highlighted. This potentially provides a basis for improved decision making, which has a significant value.
