    South Africa has one of the highest Human Immunodeficiency Virus (HIV) prevalence rates in the world. People living with HIV/AIDS experience many unrelieved symptoms. Nutritional care and support are important in preventing development of nutritional deficiencies. Home remedies can extend and improve the quality of their lives. Home remedies treatment involves eating healthy food, avoiding certain types of foods, psychological and emotional support and practicing hygiene to avoid skin infections (Sizani, Bandile; Nikiwe 2012). HIV/AIDS treatment and management strategies require ongoing management and support. In this research, we work with people from a clinic in Gugulethu Township in Western Cape, South Africa. The area has high prevalence of HIV (Ministry of health South Africa 2011). Most of the HIV patients in this area access medical information by walking long distances to the clinic. Most of these patients are poor and sometimes cannot afford to visit the clinic regularly for medical advice. In this township there is scarcity of health care workers (HCWs). The HCWs toil on many fronts to meet the enormous demand for the HIV/AIDS services but they are not able to meet the patients' needs. The aim of this research is to empower HIV-patients to self-manage the HIV-related symptoms which they experience. We investigated the way in which the HCWs deliver information to the patients. We interviewed the patients to understand what measures they take to manage the symptoms which they experienced. Consequently, we developed an advisory expert system to enhance Home-Based Care for HIV patients. An advisory expert system is defined as a computing system which is capable of representing and reasoning about some knowledge–rich domain, with a view to solving problems and giving advice (Gustafson et al. 1994). Since South Africa has high mobile phone penetration and most of the patients own them, we opted to use mobile phone as a tool to access the information provided by the advisory expert system. The system was then deployed at the clinic. We trained both HCWs and patients how to use the system. The findings were captured and reported after a six month deployment of the system. The results show that our system can be used as an effective tool to disseminate nutritional and psychological support information to HIV- patients in Gugulethu. The system is simple, yet practical. It helps the patients to self-manage the HIV-related symptoms which they experienced and at the same time, saves time and cost for both HCWs and the patients

    Cloud Manufacturing (CM) is the concept of using manufacturing resources in a service oriented way over the Internet. Recent developments in Additive Manufacturing (AM) are making it possible to utilise resources ad-hoc as replacement for traditional manufacturing resources in case of spontaneous problems in the established manufacturing processes. In order to be of use in these scenarios the AM resources must adhere to a strict principle of transparency and service composition in adherence to the Cloud Computing (CC) paradigm. With this review we provide an overview over CM, AM and relevant domains as well as present the historical development of scientific research in these fields, starting from 2002. Part of this work is also a meta-review on the domain to further detail its development and structure

    Abstract. Knowledge is an important resource that enables organizations to survive in an ever-changing environment. The basic conceptual structure that describes the processes of internal knowledge transfer and transformation is a knowledge management framework, which serves as a foundation for an effective knowledge management strategy. Software engineering processes have some inherent knowledge management in them, but the process alone does not adequately address knowledge management. The main research question was what kind of research has been done on knowledge management frameworks in software engineering. Three assisting research questions were formed to answer the main research question: What types of papers are being published? What are the keywords covered by the knowledge management framework publications? What types of scientific contributions have the publications made? This thesis used mapping study to get an overview into the research efforts made regarding knowledge management frameworks in software engineering. The study used 76 papers from the database of Institute of Electrical and Electronics Engineers (IEEE), which were examined and assigned to multiple categorization schemes, which included research type, keyword coverage, research context, contribution facet and the knowledge management framework type. These resulting categorisations were used to determine the answers to research questions and give insight into the efforts made on knowledge managements frameworks. The results suggest that the efforts on knowledge management frameworks have been consistent over the last 20 years with a peak that corresponds to the popularity trend of research on knowledge management. The publications have been emphasizing few key areas in each categorization scheme. The areas that lack publications are identified, which indicate a research gap

    The focus of this research was on the product development expertise of Irish SMEs. In particular, SMEs developing physical products (a physical product is defined as an electronic, medical device, plastic or general engineering product). A survey of Irish SMEs was conducted across industry sectors developing physical products with the objective of understanding how indigenous SMEs and therefore Ireland is progressing towards becoming a knowledge economy. SME characteristics (customers and markets, organisational structures, systems, processes and procedures, human and financial resources, culture and behaviour) were researched and used to understand the issues SMEs have with product development (PD research is mostly considered from the perspective of large companies). In relation to product development: strategy, innovation and learning, strategic techniques, organisational structure, product development process design, types of product development processes, tools and methodologies, technology, intellectual property, change management, marketing and branding and performance measurement were all examined. Survey items (variables) were identified from the literature review and used to create a survey designed based on ‘best practice’ PD and SME characteristics. This survey was conducted based on identified survey best practice in order to increase response rate and went through two pre-tests and a pilot before the final study. Descriptive analysis, reliability/consistency analysis and regression analysis were conducted on the constructs of product development. Specific relationships identified in the literature review were examined. The results of this analysis revealed that Irish SMEs are operating in a ‘Knowledge Based Development’ or learning environment. They carry out many of the techniques associated with various tools and methodologies but reported no use of these T&M which could aid their approach. There is a high use of technology, especially CAD and technology is mostly developed within the product development process. There was a high use of Cross Functional Teams and in general strategy and fuzzy front end/voice of the customer usage was carried out well. There were no issues with change management and in relation to intellectual property the use of an IP policy, strategy and portfolios was low. Generally, Irish SMEs are ready to reach the next stage of company evolution by linking ‘organisational (innovation) processes’

    Idea Management: Enhancing External Innovation Capabilities within Front-End Activities

    Get PDF
    This study examines and verifies the factors influencing idea management in enhancing external innovation capabilities within front-end activities in large organisations. Previous studies have identified idea management as being in serious need of better management. This research aims to address this need by adding new knowledge and understanding to how organisations generate, search and select ideas internally and externally. Innovation is rapidly becoming a strategic priority, but there is a large gap between the perceived importance of innovation and the effectiveness of approaches used to support innovation. Idea management works under the premise that the innovation process is too important to be left to chance. Ideas are the starting point to every innovation. This research examines the concept of idea management, which acknowledges the importance of external ideas within the innovation process. External sources offer a huge amount of knowledge and ideas, much of which is unexpected and can therefore promote disruptive innovation. Idea management is characterised by a high degree of complexity and must be organised efficiently in order to work in the long-term. It is well established that there is a general lack of clarity, definition and understanding within the front-end of innovation in terms of language, processes and activities. This is why it is also referred to as the fuzzy front-end, occurring prior to when an idea receives formal funding. Several key activities include opportunity identification, problem definition, environmental scanning, and idea generation and evaluation. These activities involve leveraging internal and external innovation capabilities and is one of the reasons why this research focuses on better understanding and visualising this interaction by improving idea management practices. This iCase award was funded by the EPSRC and the multinational consumer goods company, Procter & Gamble (P&G). The research outcomes are of interest to large organisations looking to enhance how they manage their internal and external ideas. On a smaller scale, effective practices for internal idea generation are identified which could be of use to SMEs. The thesis will add to the field of front-end innovation literature regarding idea management effective practices, supported by quantitative data on a global scale. A blended methods approach was used where insights were verified through iteration between a systematic literature review, front-end model comparison, global industrial interviews, and a main survey conducted within P&G. This organisation is well known for their success with external search practices for innovation. The industrial interviews were conducted with P&G’s ‘Connect + Develop’ practitioners and were vital to gain an understanding of language and challenges related to the research questions. This guided the development of an industrial survey which assessed the effectiveness of an idea sourcing tool adopted by P&G. The findings from the survey provide further insight into how innovation landscaping tools are used in practice and ways in which to increase levels of tool adoption. This research finds that organisations do want to find and leverage high quality ideas but are unsure of how to best search for and select them. The proposed ‘Idea Infinity Framework’ helps to visualise, orientate and kick-start search and select processes in organisations. It argues that visualising the sources, interactions and issues to be aware of for idea quality will improve the effectiveness of front-end activities, as well as make better use of practitioner time, effort and funds. This study argues that idea management should take a proactive approach rather than a passive approach to the management of ideas (i.e. search and select) and become more integrated

    Lean Thinking For Lead-Time Reduction And Efficient Knowledge Creation In Product Development

    There are many distinct differences between manufacturing process and Product Development (PD) process, so lean tools have to be customized to deliver results in the later domain. The main focus of this dissertation is to extend them to manage and improve the PD process in order to develop the product faster while improving or at least maintaining the level of performance and quality. For aforesaid purpose, value stream mapping (VSM) method is used to explore the wastes, inefficiencies, non-valued added steps in a single, definable process out of complete PD process. Besides numerous intangible benefits, VSM framework will help the development team to reduce the lead-time by over 50%. Next, a set of ten lean tools and methods is proposed in order to support and improve efficiency of the knowledge creation (KC) process. The approach establishes a KC framework in PD environment, and systematically demonstrates how these lean tools and methods conceptually fit into and play a significant role in enhancing the performance of KC process. Following this, each of them is analysed and appropriately positioned in a SECI (socialization-externalization-combination-internalization) mode depending on the best fit. Quick and correct KC at the right time aids in further improving the development lead-time and product quality. Such successful innovation is often associated with adoption and execution of all SECI modes within any PD phase. This dissertation attempts to argue with this general notion and to distinguish different PD phases\u27 affinity corresponding to distinct SECI mode. In this regard, an extended Fuzzy Analytic Hierarchy Process (EFAHP) approach to determine the ranking in which any PD phase is influenced from SECI modes is proposed. In the EFAHP approach, the complex problem of KC is first itemized into a simple hierarchical structure for pairwise comparisons. Next, a triangular fuzzy number concept is applied to capture the inherent vagueness in linguistic terms of a decision-maker. This dissertation recommends mapping the triangular fuzzy numbers (TFNs) with normal distributions about X-axis when the pessimistic value of one TFN is less than the optimistic value of other TFN (t23 ≀ t11). This allows us to develop a mathematical formulation to estimate the degree of possibility of two criteria as opposed to zero resulted by the use of the current technique in the literature. In order to demonstrate the applicability and usefulness of the proposed EFAHP in ranking the SECI modes, an empirical study of development phase is considered. After stringent analysis, we found that the combination mode was the mode that highly influenced the development phase
