Pervious pavements in car parks and driveways reduce peak discharge and the volume of runoff flowing in to urban drains and improve the water quality by trapping the sediments in the infiltrated water. This reduces the risk of pollutants such as suspended solids and particle bound chemicals such as phosphorous, nitrogen, heavy metals and oils and hydrocarbons entering receiving waters. The key objectives of the study are to establish relationships between rainfall and pervious pavement runoff and quantify improvements to infiltrated stormwater quality through the pervious pavement. The field experimental results were used to calibrate the PCSWMMPP model and to develop water flow and quality improvement transfer functions of the MUSIC model for concrete block and turf cell pavements. The research reported herein has demonstrated that pervious pavements can be introduced as a sustainable stormwater management initiative and as a key Water Sensitive Urban Design feature to deliver numerous benefits to the environment. The outcomes from the study will be useful in designing environmentally friendly car parks, pedestrian paths, light traffic drive ways, sporting grounds and public areas in the future. Land developers and local government authorities will be major beneficiaries of the study which has increased the understanding of the use of pervious pavements and explored a number of issues that previously inhibited the wider use of pervious pavements in practice.

There can be little doubt that Six Sigma is far more than just another novelty concept; in fact, it can be considered as a proven quality philosophy and if applied correctly, ensures a competitive advantage. A rapidly increasing number of firms, from all industries and of all sizes, are now reporting significant savings or returns on their program and training investments, because of the implementation of Six Sigma. This paper investigates the origin, definition, financial benefits and challenges of Six Sigma and its implementation. Certain critical success factors determine the successful implementation of Six Sigma in any firm. Many firms have reported significant benefits as a result of Six Sigma project implementation, though not all are yet success stories. This paper reviews the literature related to the critical success factors for the effective implementation of Six Sigma. This research will provide the useful information for firms, which are willing to implement Six Sigma and help firms avoid the risks during the process of Six Sigma implementation. The primary objective of this exploratory research is to identify the critical success factors required for the successful implementation of Six Sigma. Then, based on the critical success factors identified in literature and the survey, the purpose is to develop and propose an applicable framework for firms to successfully implement Six Sigma. The research is explorative of nature and a survey research design was used with a questionnaire as data-gathering instrument. Descriptive statistics (e.g. means and standard deviations) were used to analyse the data. The results confirmed that the most critical success factors for successful Six Sigma implementation include management commitment, change management, effective communication and alignment. The proposed framework presents six interlinking components of Six Sigma which is dependent on these four critical success factors. Limitations in the research are identified and recommendations for future research are made. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2009.

As the airline industry continues to rapidly expand and evolve, today's airlines leaders are faced with the challenge of balancing long term strategies with short term solutions. Customer satisfaction has become significantly important for airline operations and as a result service quality has also gained paramount importance in this sector. Lean's customer-focused theme for improving service quality has gained a momentum in services, however, Lean deployment within the airline service sector is generally a long way behind manufacturing and health services. These factors have motivated research into investigating Lean phenomena within a leading UK airline company. For quantitative and qualitative data analysis, 9 cases were collected from 3 internal departments of the airline company, 35 semi-structured interviews were held, and 220 survey questionnaires were circulated of which 180 were returned. Within-case and cross-case analysis techniques were applied and, to develop a framework and 5 key relationships were identified. This study’s contribution is in the area of Quality Management as it: (a) highlights the role of ‘customer value’ and ‘engagement value’ in the domain of technical and functional service quality attributes; (b) maps cost-quality-delivery relationships through linking Lean improvements to its results; and (c) constructs an ‘outcome-driven’ framework from the findings. Ultimately, this research provides knowledge and understanding of how an airline company deploys Lean as business strategy to improve their service quality. The novelty of the research in terms of deliverables is two-fold: firstly, it establishes framework linking Lean improvement initiatives to its results, which extends to the sustainability, commitment, future profitability and market share characteristics of improvement results; and secondly, it provides a tool, which could assist key decision makers in evaluating the results of the Lean initiative to provide better understanding for Lean deployment. Key words: Lean services; business improvement strategy; service quality improvements; quality management; airline services; customer satisfaction; employee satisfaction.

The purpose of this master's degree thesis was to develop an understanding of how hospital management, in the case studied, worked to achieve changes in an organization influenced by differing professional cultures. To gain insight into the conditions that may have contributed to nurses and physicians developing appropriate attitudes and behaviours, which may have affected the organization's ability to achieve the Swedish Quality Award 2012.  A qualitative single case study was conducted at Karlskoga Hospital, with focus groups as well as individual depth interviews.   The results of the case study showed the following conditions provided nurses and physicians the potential to develop appropriate attitudes and behaviours, which may have influenced the hospitals ability to achieve the Swedish Quality Award:   Responsibility and influence over the development processes. Participation in management teams and quality development groups as well as individual fields of responsibility. Training programs that have given insights and skills in quality management related to clinical practice. Nurses and physicians as key individuals gave legitimacy to development process, and served as management advisors. Collaboration between all kind of employees and responsibilities. Committed management.

Bakgrund: Sjukfrånvaron i Sverige 2004 var högst i Västeuropa och landets enskilt största ekonomiska problem. Regeringen vidtog åtgärder för att minska sjukfrånvaron. En del var att ge incitament för att sjukskrivningsprocessen skulle finnas med i hälso- och sjukvårdens ledningssystem, delvis på grund av förändrade krav och därmed brister i läkarintygens kvalitet. En lokal undersökning vid ortopedkliniken Kärnsjukhuset visade att 23 % av patienterna var missnöjda i samband med sjukskrivning. Syfte: Genom Sex Sigmas problemlösningsmodell DMAIC i kombination med mikrosystemperspektivet förbättra kvaliteten på läkarintygen, skapa mål och rutiner i sjukskrivningsprocessen samt öka patientnöjdhet  Metod: Utifrån ett mikrosystemperspektiv intervjuades projektgruppsdeltagare. Genom Sex Sigmas problemlösningsmodell fokuserades förbättringsområden på informationsutbyte till patienter och läkare samt utformande av mål och skriftliga rutiner. Femtioåtta patienter intervjuades om hur nöjda de var med sin sjukskrivning. Mätningar av ”onödiga” åtgärder utfördes och kvaliteten i läkarintygen följdes med styrdiagram. Förbättringsprojektet utvärderades kontinuerligt genom reflektion i projektgruppen. Resultat: Förbättringsarbete med hjälp av Sex Sigma och mikrosystemperspektiv har bidragit signifikant till ökad kvalitet i läkarintygen, p<0,001. Rutiner och mål för sjukskrivningsprocessen har implementerats i ledningssystemet. Hundra procent av patienterna på ortopedkliniken är nöjda och telefonsamtal om brister och felaktiga ärenden har minskat. Förbättringsmetodiken har bidragit till ett vidgat synsätt, ökad förståelse för patienten och mellan personalkategorier. Åtgärderna har haft genomslagskraft genom att förbättringsförslagen kom från dem som arbetar i verksamheten och genomfördes med egen personal. Diskussion: Sex Sigma och mikrosystemperspektivet har patientfokus vilket kan påverka värderingar och vilja till förändringar. Resultatet från denna studie stöder det som kommit fram i andra studier och arbetssättet gav signifikant förbättrat resultat. Förbättringsåtgärderna är inte generaliserbara men arbetssättet kan med fördel tillämpas i förbättringsarbete. Ytterligare studier av arbetssättet och dess hållbarhet över tid behövs för att stärka evidensen. / Background: The sickness absence in Sweden 2004 was highest inWestern Europe and the country's main economic problem. The government gave incentives to make the sick-leave process included in healthcare management system, partly because of changing requirements and deficiencies in the quality of medical-certificates quality. A local study at an orthopedic clinic showed that 23% of patients were dissatisfied with sick-leave. Purpose: Through Six Sigma's DMAIC problem-solving model in combination with micro-systems perspective, improving the quality of medical certificates, create goals and routines in the sick-leave process and increase patient satisfaction Method: Interviews of project participants were carried out using a micro-systems perspective. Through Six Sigma problem-solving model areas of improvement were focused on information exchange to patients and physicians as well as formulating goals and written routines. Fifty-eight patients were interviewed about their sick-leave satisfaction. Measurements of "unnecessary" actions were performed and the quality of medical certificates was followed with control-charts. The improvement project was evaluated by reflection in the group continuously. Results: Improvements with Six Sigma and micro-systems perspective has contributed to improving the quality of medical certificates significantly p<0.001. Routines and goals for sick-leave process have been implemented in the management system. 100% of the patients at the orthopedic clinic are satisfied. Phone calls about deficiencies and incorrect cases have decreased. This methodology has contributed to a broadened understanding of patients´ experiences and between different staff-categories. The actions have had impact because the improving proposals came from and were carried out by its own staff. Discussion: The Six Sigma and the micro-systems perspective has patient focus which can affect the values and willingness to change. The result from this study supports other studies and the approach in this study resulted in significantly improved results. Improvement actions are not generalizable, but the approach can be usefully applied in improvement efforts. Further studies of the approach and its sustainability over time are needed to strengthen the evidence.
