Quality management maturity: Its application and evaluation in Chinese private equipment manufacturing enterprises

Although China’s private equipment manufacturing enterprises have made significant progress, quality problems still occur because of the weak quality foundation. Therefore, it is necessary to scientifically evaluate the quality management of equipment manufacturing enterprises, identify the deficiencies and defects of quality management, and provide systematic and targeted countermeasures and suggestions. The thesis conducted text analysis on the quality award self-assessment materials of three companies and constructed an evaluation model for private equipment manufacturing enterprises including four sub-systems (management process, support process, customeroriented process and result) through three-level coding. Meanwhile, in order to empirically test the quality management maturity evaluation model of private equipment enterprises and explore the relationships between the sub-systems, the thesis selected 6 private equipment enterprises located in Guizhou province as the pre-survey objects and selected 80 private manufacturing enterprises located in Beijing, Zhejiang province, Guizhou province, Hunan province, and Sichuan province as the formal survey objects to carry out hypothesis test. Moreover, the thesis developed a maturity evaluation scale. Applying the scale to the case GXTF company, the thesis proposed improvement strategies for GXTF company. In theory, the thesis enriched the research on the quality management of private equipment manufacturing enterprises. In practice, the thesis provided reference for maturity evaluation, and provided an updated version for GJB9001C quality management accreditation institutions.Embora as empresas de manufaturação privadas da China têm feito progressos significativos, existem ainda problemas de qualidade uma vez que as fundações para a qualidade são débeis. Por isso mesmo, é relevante avaliar de forma científica a gestão da qualidade das empresas de manufaturação, bem como, identificar os defeitos e as deficiências da gestão da qualidade nessas mesmas e, por fim, apresentar sugestões e medidas de melhoria. Esta tese conduziu um estudo com base em procedimentos de auto-avaliação para concurso de prémios de qualidade fornecidos por três empresas e construiu um modelo de avaliação da maturidade da gestão da qualidade com quatro subsistemas (processo de gestão, processo de suporte, processo de foco no cliente e resultados) e três níveis de desempenho. Com o intuito de o testar empiricamente, foram selecionadas 6 empresas particulares de manufaturação da província de Guizhou para o pré-teste. E ainda, foram selecionadas 80 empresas sediadas em Beijing, nas províncias de Zhejiang, de Guizhou, de Hunan e de Sichuan para formalmente testar as hipóteses do odelo. Por outro lado, concebeu-se um guião para análise de processos de maturidade da gestão de qualidade e foi selecionada a empresa GXTF para este estudo. Contribuímos para a teoria com o enriquecimento da investigação da gestão da qualidade em empresas de manufaturação. E, contribuímos para a prática da gestão, com um novo modelo de avaliação da maturidade da gestão da qualidade e ainda de elementos para a atualização da norma GJB9001Cl da gestão da qualidade

ISO/IATF16949 a Lean Manufacturing Framework or a Wasteful Process

The Quality Management Systems in automotive industry known as ISO/TS16949 which recently has been updated into ISO/IATF16949:2016 developed by western major car manufacturers as an alternative approach for Total Quality Management (TQM). As it is not tailor-made for each of the western OEM's, however by introducing customer specific requirements to the requirements made it more suitable for OEM's to monitor and manage the quality and reliability of the products and processes throughout the supply chain. On the other hand, the lean philosophy is a key for cost reduction and in simple words 'do more with less'. As by some, the processes and the significant costs of certification and maintaining the certification is being considered as wastes, without taking into account the benefits, this study is striving to clarify this picture. The scope of the study is a OEM which I was working in last 18 months and my intention is to demonstrate whether with a serious commitment to IATF QMS the well known lean wastes in manufacturing reduces or not. The two departments including Warranty Claims (For all models) and Maintenance (Assembly and Body-In-White) performance measures reviewed and analysed as they are their performance can indicate wastes and success of lean manufacturing. The results of this study denote a significant improvement in Warranty claims and a considerable improvement in efficiency and effectiveness in Maintenance teams after improvement in QMS.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Cloud enterprise resource planning development model based on software factory approach

Literature reviews revealed that Cloud Enterprise Resource Planning (Cloud ERP) is significantly growing, yet from software developers’ perspective, it has succumbed to high management complexity, high workload, inconsistency software quality, and knowledge retention problems. Previous researches lack a solution that holistically addresses all the research problem components. Software factory approach was chosen to be adapted along with relevant theories to develop a model referred to as Cloud ERP Factory Model (CEF Model), which intends to pave the way in solving the above-mentioned problems. There are three specific objectives, those are (i) to develop the model by identifying the components with its elements and compile them into the CEF Model, (ii) to verify the model’s deployment technical feasibility, and (iii) to validate the model field usability in a real Cloud ERP production case studies. The research employed Design Science methodology, with a mixed method evaluation approach. The developed CEF Model consists of five components; those are Product Lines, Platform, Workflow, Product Control, and Knowledge Management, which can be used to setup a CEF environment that simulates a process-oriented software production environment with capacity and resource planning features. The model was validated through expert reviews and the finalized model was verified to be technically feasible by a successful deployment into a selected commercial Cloud ERP production facility. Three Cloud ERP commercial deployment case studies were conducted using the prototype environment. Using the survey instruments developed, the results yielded a Likert score mean of 6.3 out of 7 thus reaffirming that the model is usable and the research has met its objective in addressing the problem components. The models along with its deployment verification processes are the main research contributions. Both items can also be used by software industry practitioners and academician as references in developing a robust Cloud ERP production facility

Modelo de medición de la productividad para fábricas de software

La productividad en las fábricas de software es dado por el esfuerzo realizado para la producción del software, siendo muy importante porque permite que las organizaciones logren una mayor eficiencia y eficacia en sus actividades. Uno de los pilares de la competitividad es la productividad, la cual está relacionada al esfuerzo requerido para cumplir con las tareas asignadas, sin embargo, no existe una forma estándar de medirla. En este trabajo, se presenta un modelo basado en Análisis Envoltorio de Datos (DEA, por las siglas del inglés Data Envelopment Analysis) para evaluar la eficiencia relativa de las fábricas de software y sus proyectos, a fin de medir la productividad en la Componente de Producción de Software de la Fábrica de Software a través de las actividades que se realizan en sus diferentes unidades de trabajo. El modelo propuesto consta de dos fases, en la cual se evalúa, respectivamente, la productividad de la fábrica de software y la productividad de los proyectos que esta realiza. Pruebas numéricas sobre 6 fábricas de software con 160 proyectos implementados en el Perú muestran que el modelo propuesto permite determinar las fábricas de software y los proyectos más eficientes.Tesi

Systematic construction of goal-oriented COTS taxonomies

El proceso de construir software a partir del ensamblaje e integración de soluciones de software pre-fabricadas, conocidas como componentes COTS (Comercial-Off-The-Shelf) se ha convertido en una necesidad estratégica en una amplia variedad de áreas de aplicación. En general, los componentes COTS son componentes de software que proveen una funcionalidad específica, que están disponibles en el mercado para ser adquiridos e integrados dentro de otros sistemas de software. Los beneficios potenciales de esta tecnología son principalmente la reducción de costes y el acortamiento del tiempo de desarrollo, a la vez que fomenta la calidad. Sin embargo, numerosos retos que van desde problemas técnicos y legales deben ser afrontados para adaptar las actividades tradicionales de ingeniería de software para explotar los beneficios del uso de COTS para el desarrollo de sistemas.Actualmente, existe un incrementalmente enorme mercado de componentes COTS; así, una de las actividades más críticas en el desarrollo de sistemas basados en COTS es la selección de componentes que deben ser integrados en el sistema a desarrollar. La selección está básicamente compuesta de dos procesos principales: La búsqueda de componentes candidatos en el mercado y su posterior evaluación con respecto a los requisitos del sistema. Desafortunadamente, la mayoría de los métodos existentes para seleccionar COTS, se enfocan en el proceso de evaluación, dejando de lado el problema de buscar los componentes en el mercado. La búsqueda de componentes en el mercado no es una tarea trivial, teniendo que afrontar varias características del mercado de COTS, tales como su naturaleza dispersa y siempre creciente, cambio y evolución constante; en este contexto, la obtención de información de calidad acerca de los componentes no es una tarea fácil. Como consecuencia, el proceso de selección de COTS se ve seriamente dañado. Además, las alternativas tradicionales de reuso también carecen de soluciones apropiadas para reusar componentes COTS y el conocimiento adquirido en cada proceso de selección. Esta carencia de propuestas es un problema muy serio que incrementa los riesgos de los proyectos de selección de COTS, además de hacerlos ineficientes y altamente costosos. Esta disertación presenta el método GOThIC (Goal- Oriented Taxonomy and reuse Infrastructure Construction) enfocado a la construcción de infraestructuras de reuso para facilitar la búsqueda y reuso de componentes COTS. El método está basado en el uso de objetivos para construir taxonomías abstractas, bien fundamentadas y estables para lidiar con las características del mercado de COTS. Los nodos de las taxonomías son caracterizados por objetivos, sus relaciones son declaradas como dependencias y varios artefactos son construidos y gestionados para promover la reusabilidad y lidiar con la evolución constante.El método GOThIC ha sido elaborado a través de un proceso iterativo de investigación-acción para identificar los retos reales relacionados con el proceso de búsqueda de COTS. Posteriormente, las soluciones posibles fueron evaluadas e implementadas en varios casos de estudio en el ámbito industrial y académico en diversos dominios. Los resultados más relevantes fueron registrados y articulados en el método GOThIC. La evaluación industrial preliminar del método se ha llevado a cabo en algunas compañías en Noruega.The process of building software systems by assembling and integrating pre-packaged solutions in the form of Commercial-Off-The-Shelf (COTS) software components has become a strategic need in a wide variety of application areas. In general, COTS components are software components that provide a specific functionality, available in the market to be purchased, interfaced and integrated into other software systems. The potential benefits of this technology are mainly its reduced costs and shorter development time, while maintaining the quality. Nevertheless, many challenges ranging form technical to legal issues must be faced for adapting the traditional software engineering activities in order to exploit these benefits.Nowadays there is an increasingly huge marketplace of COTS components; therefore, one of the most critical activities in COTS-based development is the selection of the components to be integrated into the system under development. Selection is basically composed of two main processes, namely: searching of candidates from the marketplace and their evaluation with respect to the system requirements. Unfortunately, most of the different existing methods for COTS selection focus their efforts on evaluation, letting aside the problem of searching components in the marketplace. Searching candidate COTS is not an easy task, having to cope with some challenging marketplace characteristics related to its widespread, evolvable and growing nature; and the lack of available and well-suited information to obtain a quality-assured search. Indeed, traditional reuse approaches also lack of appropriate solutions to reuse COTS components and the knowledge gained in each selection process. This lack of proposals is a serious drawback that makes the whole selection process highly risky, and often expensive and inefficient. This dissertation introduces the GOThIC (Goal- Oriented Taxonomy and reuse Infrastructure Construction) method aimed at building a domain reuse infrastructure for facilitating COTS components searching and reuse. It is based on goal-oriented approaches for building abstract, well-founded and stable taxonomies capable of dealing with the COTS marketplace characteristics. Thus, the nodes of these taxonomies are characterized by means of goals, their relationships declared as dependencies among them and several artifacts are constructed and managed for reusability and evolution purposes. The GOThIC method has been elaborated following an iterative process based on action research premises to identify the actual challenges related to COTS components searching. Then, possible solutions were envisaged and implemented by several industrial and academic case studies in different domains. Successful results were recorded to articulate the synergic GOThIC method solution, followed by its preliminary industrial evaluation in some Norwegian companies
