A Prototype Method and Tool to Facilitate Knowledge Sharing in the New Product Development Process

New Product Development (NPD) plays a critical role in the success of manufacturing firms. Activities in the product development process are dependent on the exchange of knowledge among NPD project team members. Increasingly, many organisations consider effective knowledge sharing to be a source of competitive advantage. However, the sharing of knowledge is often inhibited in various ways. This doctoral research presents an exploratory case study conducted at a multinational physical goods manufacturer. This investigation uncovered three, empirically derived and theoretically informed, barriers to knowledge sharing. They have been articulated as the lack of an explicit definition of information about the knowledge used and generated in the product development process, and the absence of mechanisms to make this information accessible in a multilingual environment and to disseminate it to NPD project team members. Collectively, these barriers inhibit a shared understanding of product development process knowledge. Existing knowledge management methodologies have focused on the capture of knowledge, rather than providing information about the knowledge and have not explicitly addressed issues regarding knowledge sharing in a multilingual environment. This thesis reports a prototype method and tool to facilitate knowledge sharing that addresses all three knowledge sharing barriers. Initially the research set out to identify and classify new product development process knowledge and then sought to determine what information about specific knowledge items is required by project teams. Based on the exploratory case findings, an ontology has been developed that formally defines information about this knowledge and allows it to be captured in a knowledge acquisition tool, thereby creating a knowledge base. A mechanism is provided to permit language labels to be attached to concepts and relations in the ontology, making it accessible to speakers of different languages. A dissemination tool allows the ontology and knowledge base to be viewed via a Web browser client. Essentially, the ontology and mechanisms facilitate a knowledge sharing capability. Some initial validation was conducted to better understand implementation issues and future deployment of the prototype method and tool in practice

Enforcing QVT-R with mu-calculus and games

Abstract. QVT-R is the standard Object Management Group bidi-rectional transformation language. In previous work, we gave a precise game-theoretic semantics for the checkonly semantics of QVT-R trans-formations, including the recursive invocation of relations which is al-lowed and used, but not defined, by the QVT standard. In this paper, we take up the problem of enforce semantics, where the standard at-tempts formality, but at crucial points lapses into English. We show that our previous semantics can be extended to enforce mode, giving a precise semantics taking the standard into account.

The critical role of history in scenario thinking: augmenting causal analysis within the intuitive logics scenario development methodology

The historian Eric Hobsbawm stated that ‘The safest empirical generalization about history is still that nobody heeds its obvious lessons much’. Whether at a macroeconomic level or within individual organisations there are numerous examples of this, such as the economic crash of 2008, the causes of which had many parallels with those that caused the great depression 80 years previously. On the other hand however, overly-relying on the past as a guide to the future has its own obvious dangers – not least that important future events may have no past precedent. As such, the present paper firstly provides a discussion of the advantages and disadvantages of using the past as a guide to the future. It then examines the role of history in scenario work, arguing that history should receive greater emphasis as part of the scenario planning process. We suggest changes to the standard Intuitive Logics (IL) approach to scenario planning which would render learning from history a more central component of the scenario process, in contrast to its current peripheral role. Rather than diminishing scenario planning’s ability to facilitate a consideration of how the future may differ from the past, we show how a greater emphasis on history can enhance consideration of the causality of future change. An adapted IL that has more emphasis on historical analysis can augment scenario planning’s effectiveness as a tool for consideration of the future

A methodology to facilitate knowledge sharing in the new product development process

This paper describes the findings of an exploratory case study to investigate knowledge sharing problems in the new product development (NPD) process of a multi-national manufacturing company, and classifies the problems into three categories, i.e. (a) the lack of an explicit definition and prioritization of information about the knowledge used in the NPD process, (b) the challenges raised by, and lack of tools to support, knowledge sharing in a multilingual, multidisciplinary environment, and (c) the dissemination of information about the task and process knowledge to process users. An ontology-based methodology has been proposed, and a pilot study has been carried out to solve these problems. The pilot study includes the selection of suitable candidate tasks (or sub-processes) for the study, the elicitation of information about the selected task knowledge, the development of task knowledge ontology, and a mechanism to visualize and disseminate the ontology to process users. Early implementation and tests have shown that the proposed methodology may be used to facilitate knowledge sharing in the new product development process. The project was sponsored by a leading heating system manufacturer and further tests will be carried out with real industrial problems

The 1997-98 summer rainfall season in southern Africa. Part I: Observations

Following the onset of the strong El Niño of 1997–98 historical rainfall teleconnection patterns and dynamical model predictions both suggested an enhanced likelihood of drought for southern Africa, but widespread dry conditions failed to materialize. Results from a diagnostic study of NCEP–NCAR reanalysis data are reported here demonstrating how the large- and regional-scale atmospheric circulations during the 1997–98 El Niño differed from previous events. Emphasis is placed on the January–March 1998 season and comparisons with the strong 1982–83 El Niño, although composites of eight events occurring between 1950 and 2000 are also considered. In a companion paper, simulation runs from three atmospheric general circulation models (AGCMs), and forecasts from three fully coupled models are employed to investigate the extent to which the anomalous atmospheric circulation patterns during the 1997–98 El Niño may have been anticipated. Observational results indicate that the 1997–98 El Niño displayed significant differences from both the 1982–83 episode and the composite event. An unusually strong Angola low, exceptionally high sea surface temperatures (SSTs) in the western Indian and eastern tropical South Atlantic Oceans, and an enhanced northerly moisture flux from the continental interior and the western tropical Indian Ocean all appear to have contributed to more seasonal rainfall in 1997–98 over much of the southern Africa subcontinent than in past El Niño events

The 1997-98 summer rainfall season in southern Africa. Part II: model simulations and coupled model forecasts

This is the second of a two-part investigation of rainfall in southern Africa during the strong El Nino of 1997/98. In Part I it was shown that widespread drought in southern Africa, typical of past El Nino events occurring between 1950 and 2000, generally failed to materialize during the 1997/98 El Nino, most notably during January–March (JFM) 1998. Here output from three atmospheric general circulation models (AGCMs) forced with observed sea surface temperatures (SSTs) and seasonal forecasts from three coupled models are examined to see to what extent conditions in JFM 1998 could have potentially been anticipated. All three AGCMs generated widespread drought conditions across southern Africa, similar to those during past El Nino events, and did a generally poor job in generating the observed rainfall and atmospheric circulation anomaly patterns, particularly over the eastern and southern Indian Ocean. In contrast, two of the three coupled models showed a higher probability of wetter conditions in JFM 1998 than for past El Nino events, with an enhanced moisture flux from the Indian Ocean, as was observed. However, neither the AGCMs nor the coupled models generated anomalous stationary wave patterns consistent with observations over the South Atlantic and Pacific. The failure of any of the models to reproduce an enhanced Angola low (favoring rainfall) associated with an anomalous wave train in this region suggests that the coupled models that did indicate wetter conditions in JFM 1998 compared to previous El Nino episodes may have done so, at least partially, for the wrong reasons. The general inability of the climate models used in this study to generate key features of the seasonal climate over southern Africa in JFM 1998 suggests that internal atmospheric variability contributed to the observed rainfall and circulation patterns that year. With the caveat that current climate models may not properly respond to SST boundary forcing important to simulating southern Africa climate, this study finds that the JFM 1998 rainfall in southern Africa may have been largely unpredictable on seasonal time scales

The seasonally-varying influence of ENSO on rainfall and tropical cyclone activity in the Philippines

An observational study covering the period 1950–2002 examines a seasonal reversal in the ENSO rainfall signal in the north-central Philippines. In boreal Summer of El Niño (La Niña) events, above (below) average rainfall typically occurs in this area. Rainfall anomalies of opposite sign develop across the country in the subsequent fall. This study investigates the seasonal evolution of the anomalous atmospheric circulation over the western North Pacific (WNP) during both El Niño and La Niña and places these features in the context of the large-scale evolution of ENSO events, including an analysis of changes in tropical cyclone activity affecting the Philippines. The results show that during boreal summer of El Niño (La Niña) events, a relatively narrow, zonally elongated band of enhanced (reduced) low-level westerlies develops across the WNP which serves to increase (decrease) the summer monsoon flow and moisture flux over the north-central Philippines and is associated with an increase (decrease) in the strength of the WNP monsoon trough via the anomalous relative vorticity. Tropical cyclone activity is shown to be enhanced (reduced) in the study region during boreal summer of El Niño (La Niña) events, which is related to the increase (decrease) of mid-level atmospheric moisture, as diagnosed using a genesis potential index. The subsequent evolution shows development of an anomalous anticyclone (cyclone) over the WNP in El Niño (La Niña) and the well-known tendency for below (above) average rainfall in the fall. Prolonged ENSO events also exhibit seasonal rainfall sign reversals in the Philippines with a similar evolution in atmospheric circulation

Proposed economic selection indices for the Simmentaler breed in South Africa

The development of economic selection indices for an integrated Simmentaler production system was described. The breeding objective was defined in terms of production-, functional- and product quality traits. Criteria included in the total index were birth- and weaning weight (direct and maternal), final weight, mature cow weight, days-to-calving, backfat thickness, tenderness and marbling. The total merit index was termed as IT = – 1.60 BWD – 1.95 BWM + 2.23 WWD + 1.75 WWM – 0.54 FW – 2.01 MCW – 13.21 CD + 4.97 BF – 2.36 T + 12.66 M. The correlation between this index and the aggregate breeding objective was 0.988. The economic superiority of the progeny from the top 40% of animals selected on their ranking in the total index, relative to the average progeny, is expected to be R 119.51.
