Network learning in global engineering services

Tran, Cong Thanh January 2019 (has links)
This study develops an integrated framework to improve understanding of network learning and value creation in global engineering services (GES). Network learning is the process that enhances firm performance through better knowledge and understanding. Prior research has developed GES network learning and value creation as a set of independent processes with customers, suppliers or intra-firm engineering units. Their practices have been fragmented, facilitating either inter- or intra-firm network learning and focusing on either GES efficiency or innovation. The absence of an integrated approach to network learning makes it difficult for researchers to understand, and for GES firms to manage. A more holistic understanding of GES network learning is urgently needed for firms to compete effectively in an ever-changing global market. This research develops the theory of integrated GES network learning and value creation through a multiple case study. It integrates existing insights from multiple streams of research, and builds on these to explore network learning within three GES firms. The empirical study reveals an integrated network learning process adopted across customers, suppliers and intra-firm engineering units which enhances GES efficiency, flexibility and innovation. It clarifies the interrelated knowledge acquisition and development processes and supporting boundary spanning mechanisms within network learning. These processes and mechanisms are integrated in a framework that offers a more holistic view of GES network learning. The framework contributes conceptually to the literature on network learning in GES and offers managerial implications for firms to facilitate integrated network learning for effective GES value creation.

Management guru

Huczynski, Andrzej Antoni January 1991 (has links)
This thesis considers how the reader can become a management guru. To this end, it examines the history of management ideas in the period 1890-1990, and identifies those which have achieved widespread popularity. A management idea is the generic term used to refer to any research finding, theory, concept, framework or prescription that maintains currency within the world of management and management education and training. The thesis accounts for the popularity of these ideas. It argues that four sets of factors contribute to the establishment of the popularity of a management idea. First, the idea has to be timely, that is, in tune with social, economic and political concerns of the period. Second, it has to achieve a high level of visibility in order to gain managers' awareness of its existence. Third, it should address the relatively stable and enduring set of managerial needs. Fourth, the idea should, in its content and design, be perceived by the managers as capable of fulfilling those needs. Five literature reviews were carried out. The first identified the six most popular management idea "families". The second was a historical review of the social, economic and political factors which formed the historical milieus from which these idea families evolved. The third literature review uncovered twelve recurring features of these popular management ideas. The fourth examined managers' needs for such ideas, and the fifth examined how management ideas were marketed by companies and consultants. These literature reviews produced a set of hypotheses, some of which were tested in the empirical part of the study. These related primarily to the link between management needs and the characteristics of the ideas themselves. Both business school academics' and managers' reactions to different management ideas were assessed from a phenomenological perspective. This utilised self-completed questionnaires and the analysis of interview transcripts. The research conclusions are that the popularity of a management idea can both be predicted and planned for by enterprising and aspiring management gurus, be they business school faculty or management consultants. The application of the principles described in this thesis should secure for them, both fame and fortune.

A mixed-method study on the effectiveness of a buffering strategy in the relationship between risks and resilience

Garrido Rios, Alexander January 2017 (has links)
The present research pursues two main interrelated objectives: one the one hand, to derive a unified definition of the concept of supply chain resilience (SCRes) from which a quantitative holistic measure of SCRes that appraises both dynamic and inherent resilience can be developed; on the other, to evaluate the theoretical effectiveness—due to the use of simulated experimental data—of a buffering strategy founded on the use of on-hand inventory buffers or short-term manufacturing capacity to build up SCRes. In this sense, the review of the literature uncovered not only flaws in the existing approaches to measure SCRes, but also opposing standpoints on the theoretical effectiveness of using a buffering strategy to inhibit the frequency/impact of SC disruptions. From the literature it is also unclear in which cases or under what circumstances the unit of analysis for this research should adopt a buffering strategy as mentioned. The unit of analysis selected for these purposes is a real-world military food supply chain (MFSC) operating in a risky environment that provides subsistence items to a medium-size military force (< 280,000 troop members). The research methods to address the two research objectives proposed are, first, a robust model based on discrete simulation; and second, an open-ended questionnaire administered to the staff of the MFSC. The first method—simulation—provides the data required to test the nine ex-ante hypotheses, while the second method—questionnaire—complements the previous ones by increasing their usefulness and empirical validity. The simulation experiment performed consists of subjecting the MFSC under analysis to the stepwise occurrence of three categories of risk—operational risks or R1r; natural disasters and intentional attacks or R2r; and black-swan events or R3—while on-hand inventory buffers or short-term manufacturing capacity—the buffering strategy—are gradually increased following an efficient experimental design. To test the nine hypotheses of the research, it was necessary to apply an approach based on data mining techniques— mining causal association rules—and non-parametric methods—the Kruskal-Wallis rank sum and Binomial distribution tests, and the Wilcoxon rank sum test with continuity correction. In this way, based on a novel perspective related to the application of the concept of tail autotomy effect (TAE) to obtain a measure of SCRes (ReT), the evaluation of the output data of the simulation model indicates that: (1) ceteris paribus, increases in the frequency of occurrence of seven of the nine risk events considered reduce ReT in the MFSC with 99% confidence; (2) increases in on-hand inventory buffers positively moderate the relationship between the frequency of occurrence of risks and ReT, with 99% confidence, regardless of the category of risk—R1r, R2r, or R3—affecting the MFSC; (3) increases in short-term manufacturing capacity positively moderate the relationship between the frequency of occurrence of risks and ReT, with 95% confidence for the categories of risk R1r and R3, and with 99% confidence for R2r; and (4) from the open-ended questionnaire, the staff of the MFSC shows a marked preference for the use of on-hand inventory buffers over short-term manufacturing capacity to avoid the occurrence of disruptions. Despite the theoretical implications of these findings, the assumptions of the simulation model, the non-inclusion of the cost factor, and the utilization of a single MFSC may limit to a certain extent their generalization to other scenarios or unit of analysis. To ameliorate these deficiencies, the construction of the simulation model incorporates nine types of risk, the evaluation of ninety configurations of the MFSC—simulation runs, and the consideration of a lengthy horizon of analysis of up to twenty years, allowing other military-SCs or even commercial-SCs can take advantage of the implications of the results of this research. Thus, from a practical point of view, this research provides (military) logisticians with clear guidelines for making decisions on when and how to use on-hand inventory buffers or short-term manufacturing capacity to create resilience or to inhibit the occurrence of disruptions caused by categories of risk R1r, R2r, and R3. From a theoretical standpoint, this research makes an original contribution to the body of knowledge in SC management by providing a novel conceptual framework mainly applicable to MFSCs, which includes the analysis of three categories of risk; a holistic measure of SCRes (ReT) including dynamic and inherent resilience; and the analysis of the application of a buffering strategy based on on-hand inventory buffers and short-term manufacturing capacity. In doing so, the findings of the research provide sufficient criteria for resolving the controversy concerning the theoretical effectiveness of the aforementioned strategy to create resilience and/or to inhibit the occurrence of disruptions in SCs.

Retail agglomeration formats and outshopping in Thai grocery market

Meeyai, Sutthipong January 2018 (has links)
Thailand has been one of the emerging markets in Asia in recent decades. The pattern of consumers has dramatically changed due to the arrival of various modern retail trade formats. Thai consumers have been shifting from traditional retail formats to modern retail formats and frequently do ‘outshopping’, particularly from rural areas to town centres. This has led to the decline of rural retailers. To improve this situation, the concept of developing retailers in market towns has been adopted. However, it is unclear what form (i.e. store format) this takes and on which factors (store image attributes and customer characteristics) the role depends. This thesis examines the effect of store image attributes and customer characteristics on retail agglomeration format choice for a regular grocery outshopping trip. The conceptual framework is constructed following the stimulus-organism-response (S-O-R) model. The concept of store image is applied as the stimulus, and the customer characteristics are proxy variables representing the organism, which lead to the choice decision as the response. The discrete choice model is applied using the mixed logit modelling approach. The choice set includes (1) a traditional agglomeration retail format (TAF), (2) a modern agglomeration retail format (MAF) and (3) a non-agglomeration retail format (NAF). The unit of analysis is a household in a regional city that does grocery shopping regularly. The stratified random sampling divided the population into an urban area and a rural area. Then, a random sample was drawn within each stratum by a simple random sampling − a store format. A systematic random sampling was applied by intercepting each household representative in order to maintain randomness. The chosen area is Nakhon Ratchasima province which is one of the regional cities in north-eastern Thailand. It consists of 2,600,000 people (around 830,000 households) and about 75% of the total population live in a rural area. The total sample consists of 1,521 households. The choice experiment is adopted by a computer-assisted personal interviewing (CAPI) survey. The parameters are estimated using the simulated maximum likelihood approach. The models are built, and then marginal effects are used to examine the effects of store image attributes and customer characteristics to the retail agglomeration format choice. Reliability and validity are tested. The results from the chosen model reveal that increases in seven store image attributes: product quality, customer service, price, travel time, atmosphere, accessibility, and range of products, affect the probability to shop at TAF and MAF with the same degree, while in store attributes have less effect on the probability to shop at NAF. The product quality, customer service level, and price are the most important attributes affecting the retail agglomeration format choice, following by atmosphere, accessibility, and range of products, respectively. The results indicate that consumers in rural areas are likely to shop at TAF and NAF than consumers in urban areas. Older rather than younger customers tend to shop at NAF. Finally, the higher income households have more opportunity to shop at MAF than the lower income households. This study employs the theory of cumulative attraction as theoretical lens of the study. However, this study contributes to the theory by examining further dimensions. The first contribution is to the theory of cumulative attraction by considering a location dimension. It investigates the role of retail agglomeration formats in market towns. The second dimension contributes to retail management by focusing on retail management style as traditional and modern retail formats. Another contribution of this study is the taxonomy of retail agglomeration formats. It indicates how retailers are planned and constructed, to what extent they are managed and marketed, and what their management styles are. This classification system can categorise existing retail formats, e.g. weekend markets, periodic markets, night markets, tourist attraction retail sites, and exhibition retail outlets which cannot be classified by the previous studies. The application of this taxonomy is applied as retail agglomeration formats in this study.

Implementation of design thinking for collaborative service innovation in SMEs : a knowledge perspective

Gao, Bin January 2019 (has links)
Innovation is a key socio-economic motivator (Laforet, 2012; Kurz, 2012). Recent studies have revealed the global innovative potential of small and medium-sized enterprises (SMEs) (Wymenga et al.; 2012, Muller, 2015). Contemporary studies suggest that, despite the role played by innovation in enabling SMEs to survive and thrive, they have been hindered by inadequate, in particular, physical resources, such as funds and technology (Laforet and Tann, 2006; Laforet, 2009). Lusch and Vargo (2008) argue that Service Dominant Logic (SDL) provides a new means of looking at value, one which emphasises that it is co-created by users and providers. Within this logic, attention focuses on service innovation, on the assumption that conventional definitions of innovation, which derive from product/ technical perspectives, do not fully explain the phenomena, particularly in SMEs (Droege et al., 2009; den Hertog et al., 2010). Service innovation is believed to result, in the main, from non-technological sources (Drejer, 2004; Carlborg et al., 2014). Lusch and Vargo (2008) stress that SDL focuses on knowledge as an essential ingredient for value co-creation, in contrast to Good-Dominant Logic (GDL), which emphasises physical or operand resources. They further argue that service innovation is a process, from which new products, services, and technologies are generated, rather than an output in the case of GDL (Mele et al., 2014; Lusch and Nambisan, 2015). Knowledge exchange as a process of value co-creation is therefore essential for service innovation. SMEs should be well placed to exploit the potential of service innovation as they are: close to their customers; have flatter structures; more effective internal communication; and possess a more positive attitude to risk-taking (Laforet, 2012). Further development of theories and definitions relating to service innovation have been called for (Droege et al., 2009), however, progress to date has been limited (Droege et al., 2009; Carlborg et al., 2014; Valtakoski and Järvi, 2016). This thesis, by adopting and contextualising as a framework the six-dimensional (6-D) model of service innovation (den Hertog et al., 2010), examines service innovation in SMEs from a knowledge perspective. This research is contextualised by an initiative, Creating Cultures of Innovation (CCoI), a Scottish Government sponsored project conducted by the Glasgow School of Art (GSA). This initiative was intended to enhance the performance of SMEs by design-led interventions, releasing the creativity of SMEs by engaging key stakeholders in collaborative knowledge exchange. A qualitative multiple case-study explores the extent to which intervention triggers both knowledge exchange and innovation. Results of this research contribute to the literature by enriching our understanding of service innovation from a knowledge perspective (Droege et al., 2009; Valtakoski and Järvi, 2016; Witell et al., 2016); by contextualising and exploring the 6-D model of service innovation in traditional SMEs (den Hertog et al., 2010); by understanding the interactions with the key stakeholders in the service ecosystem of an organisation (Carlborg et al., 2014; Mele et al., 2014; Lusch & Nambisan, 2015); and, by providing empirical evidence for the development of SDL in a context of non-knowledge intensive SMEs (Lusch & Nambisan, 2015). Practically, this research also provides a service innovation lens through which the CCoI initiative may be evaluated. From an operational perspective, the research suggests a means, design thinking interventions, by which traditional SMEs exploit service innovation. Lastly, the results provide an insight for policy makers wishing to enhance the innovative performance of Scottish SMEs.

Regulating asset ownership : capabilities and market failures in infrastructures

Rossi, Enrico January 2017 (has links)
The regulation of assets and infrastructures has always been a central problem of economic theory. The first approach of regulatory and antitrust authorities was to regard assetownership as a source of welfare inefficiency. This was the “monopoly explanation” that was contested by Coase. Developing from Coase’s original intuitions, a contractual approach emerged in regulatory economics. This second tradition relies on the concept of transaction costs, or market failures, to justify the role of ownership for welfare and regulatory purposes. Yet, even though in the contractual approach ownership is not regarded as a necessary source of welfare inefficiencies, it still remains the necessary consequence of some dysfunctional characteristic of the market mechanism. This study addresses the role of asset ownership understood in terms of the owner’s subjective use value. The aim is thus to provide a theory of ownership based on a reinterpretation of the concept of value, relying on the classical dualism between value-inexchange and value-in-use. Private ownership of a good or resource becomes relevant for welfare and efficiency purposes whenever assets can be redeployed internally across alternative subjective opportunities by the owner to satisfy their private, subjective, requirements. Through in-house redeployment, the asset owner becomes independent of the performances and requirements of external market mechanisms. If auto-employment is allowed, then two conditions are satisfied. First, the performance of the market mechanism becomes unnecessary to understand how assets are allocated among alternative uses. This makes market failures and transaction costs a non-necessary requirement to justify asset ownership and to understand its welfare implications. Second, the knowledge of an actor’s subjective capabilities in the use and employment of the asset (knowing how an actor prefers to privately use and consume an asset) becomes necessary in order to understand how different ownership patterns affect the set of idiosyncratic opportunities perceived by different potential assets owners. If auto-redeployment (in-house enjoyment or auto-consumption) is allowed, then we can see that the idiosyncratic opportunities perceived by the actors are not necessarily driven by external market mechanisms, nor by its performance. Yet, they remain relevant in order to derive normative conclusions on the allocative outcomes. This can be seen as a make-or-buy problem where the trade-off between “make” and “buy” can be reinterpreted as a trade-off in value terms, between subjective value-in-use and objective value-in-exchange. The different interpretation of the make option marks the difference between the make-or-buy problem modelled in the contract-based theory of ownership versus a capability based theory of ownership. The work argues that, whenever physical assets are privately owned and can be employed “in-house”, in order to legitimately derive normative conclusions on how privately owned assets ought to be employed in a society, some form of public regulation is always needed in order to overcome the inherent presence of subjective (actor-specific) valuations. For this reason, the work concludes that whenever value in not a monism, the legal framework should always have logical and temporal priority over the competitive mechanism of the market, independently from the performance of the latter.

A multi-study investigation of the role of psychological needs in understanding behavioural reactions to psychological contract breach

Chang, Chiachi January 2018 (has links)
A significant body of empirical work attests to the negative consequences of psychological contract breach for employees and organizations. Two dominant explanations draw on social exchange theory and affective-events theory arguing that breach influences employees’ felt reciprocity and feelings of violation respectively, which in turn influences their contributions at work. However, breach has been found to produce stronger effect on attitudes versus behaviours (Conway & Briner, 2009), suggesting that there is insufficient knowledge about employees’ motivation after the experience of psychological contract breach. Herein lies the starting point of this thesis, which adopts a thwarted psychological need perspective to examine the motivational mechanism between psychological contract breach and employees’ behaviour. The focus on thwarted needs offers an alternative explanatory reason for why psychological contract breach matters, and extends the impact of breach from cognitions and emotions to psychological needs. With three empirical studies, this thesis aims to explore the role of thwarted need to control in understanding how employees’ respond to psychological contract breach. Study 1, a scenario-based experiment, supports the idea that breach can thwart employees’ state of need to control, which can in turn influence their intentions to engage in citizenship behaviours. Study 2 consists of a time-lagged survey with multi-source data of 163 Taiwanese employees in the service industry. The study findings reveal that thwarted need to control mediates the effect of breach on employees’ citizenship behaviours, and that employees’ implicit theories of employee-organization relationship moderates this mediating process. Study 3 consists of a three time-point survey of 124 EMBA Taiwanese employees over a six-month period. Study 3 replicates and extends the findings of study 2 by demonstrating that thwarted need to control provides a unique explanation (beyond established mechanisms such as felt obligation and feelings of violation) to explaining why employees withdraw their citizenship behaviour towards individuals, demonstrating its uniqueness in the aftermath of employees’ breach experience. This thesis expands existing knowledge of why psychological contract breach matters, and discusses the implications and directions for future research.

Exploring the interrelationship between the meanings of homeownership and identity management in a liquid society : a case study approach

Smith, Alexander January 2017 (has links)
Identity research in consumer studies typically perceives consumers as bearers of fragmented, multiple postmodern identities. Contemporary social theory, broadly supporting this perspective, suggests that tradition is no longer required for the successful construction and maintenance of an identity. Unfettered from the restrictions of tradition, identities are asserted to have been liberated from the impositions of social and cultural institutions. However, this perspective appears to neglect the notion that individuals might actually desire tradition and social practice to develop a coherent, stable sense of self. This thesis explores the meanings of tenure - private renting and owner-occupation - to elucidate how these deeply felt connotations can affect individuals’ identities and their sense of self. In doing so this thesis articulates how the prospective consumption, or non-consumption, of a traditional practice – home ownership - can potentially have profound implications for one’s identity, overall sense of self and consumption behaviour. The results of this thesis were generated by conducting 30 qualitative interviews with private renters aged between 24 and 30 years old in Stoke-on-Trent using a case study approach. The findings indicate that identities are heavily influenced by the different meanings and interpretations of private renting and owner-occupation. Furthermore, the role of tradition to identity, and in particular to an overall coherent sense of future self, was found to be highly salient. Contextualised by Zygmunt Bauman’s ‘Liquid’ sociology, the findings of this study suggest that a threatened sense of future self can engender identity and consumption related practices that seek to affirm, re-affirm and defend one’s sense of self against stigmatising discourses.

Instigating transformational changes : an interdisciplinary approach based on the appraisal theories of emotion

Kitsos, Evangelos January 2016 (has links)
Recent research has questioned the commonly accepted notion that transformational changes are instigated when compelling evidence establishes a clear sense of urgency for action. Following these intriguing results, this thesis set out to investigate why some leaders avoid taking action even when a crisis is threatening their systems. For that reason, a sophisticated interdisciplinary approach was designed, which allowed insights from the discipline of psychology and the study field of management to be reviewed and meta-synthesized into a conceptual framework that expands the myopic paradigm of urgency and thereby elaborates the process of change instigation. The findings suggest that once a crisis is faced, leaders engage in an emotional change process during which the compelling evidence is appraised in reference to business goals and ego-commitments. These appraisals give rise to negative emotions as they inform the individual of the encountered threat. As a result, a self-protective regulatory mechanism is triggered, the operations of which determine the future of subsequent appraisals and thus the response to be adopted. That is, action might be taken to secure business continuation (adaptive), or the leader could trigger defence mechanisms (maladaptive) and thus respond in ways which might go against organizational interests, but protect the threatened ego. Although the theorization has not yet been empirically validated, the thesis bears significant contributions to knowledge. It demonstrates that urgency a) is a necessary yet insufficient element of the emotional change process; b) provides a superficial explanation of how transformations are instigated. Its logic is grounded in the outdated assumption that human beings are purely cognitive, cold and rational processors of information. Instead, the suggested framework emphasizes the important role that the unconscious hot cognitions and the emotional experiences play. Ultimately, through the analysis of more than 1200 multi domain sources, this theorization provides a viable alternative to the current urgency paradigm. It facilitates the diagnosis of defensive appraisals and paves the way for the development of tools to assist the agents of change.

What drives innovation and productivity? : a case study using data for German firms

Mansour, Mazen January 2017 (has links)
This work attempts to explain the relationship between innovation expenditure, innovation outputs, and firm productivity. It investigates the key factors that drive these relationships using unbalanced German manufacturing panel data at firm level captured by the Mannheim Innovation Panel (MIP) between 2003 and 2013. A structural equation model is employed to test the data consisting of three stages proposed by the Crepon, Duguet, and Mairesse econometric model (CDM) framework. The first stage is a Heckman model to control for selection bias and to explain the firm’s decision if participating in innovation activities or not, and the level of expenditure on innovation in relation to its previous labour productivity. The second stage is the knowledge production function in which innovation expenditure generates economically valuable knowledge in the form of different types of innovation. The third stage is the production function, which describes the relationship between generating innovation and labour productivity. This work focuses on testing the CDM and the expansions on process innovation and organisational innovation in the production function using the Principal Component Analysis (PCA) approach. The results imply that the firm’s decision to involve itself in innovation activities is positively associated with its previous labour productivity. However, for those firms which participate in innovation activities, the previous labour productivity affects the level of expenditure on innovation negatively. The estimation results of the knowledge production function suggest that product innovation in the form of new to the firm of clearly improved products rises with innovation expenditure. The estimation results of the production function promote the role of presenting market novelties, process innovation targeted at the reduction of average costs, and organisational innovation as sources for labour productivity. A set of determinants that might affect innovation and productivity were investigated. The empirical results suggest that market novelties are driven by qualified personnel, however, this study was unable to find drivers for process and organisational innovations.
