Proposta de um modelo para a avaliação e ações de melhoria na gestão da Segurança e Saúde no TrabalhoFranz, Luís Antonio dos Santos January 2009 (has links)
Esta tese contempla a avaliação de maturidade, a metodologia Seis Sigma e a gestão da Segurança e Saúde no Trabalho (SST). Teve-se como objetivo geral propor e desenvolver um modelo para a avaliação e ações de melhoria na gestão da SST, sustentando-se nos conceitos provenientes essencialmente da avaliação de maturidade e da metodologia Seis Sigma. Este objetivo foi alcançado por meio de atividades de levantamento, análise e classificação do referencial bibliográfico pertinente; aplicação de um survey; construção de um modelo tendo em conta os resultados do survey e a base teórica analisada; entrevistas complementadas pela decorrente análise de conteúdo. Como resultados do levantamento bibliográfico, verificou-se uma predominância de técnicas com foco em ações pontuais quando se pretende buscar melhorias na área. Em termos de avaliação de maturidade, identificou-se que predomina ainda a concepção de modelos com cinco níveis de maturidade, que os modelos são normalmente estruturados por meio de grades de maturidade, e ainda, que são pouco freqüentes as aplicações para fins de avaliação na área de SST. Mostrou-se relevante o uso de características organizacionais como, por exemplo, a existência de serviços internos de SST e de certificações na área, setor de atividade econômica ou quantidade de subcontratados, para diferenciar cada unidade organizacional quanto a sua dificuldade em mudar o nível de desempenho na gestão da SST. Isso auxilia na avaliação e tratamento diferenciado dos problemas ou oportunidades, principalmente no que tange às práticas de gestão. Também, comprovou-se junto aos responsáveis pela gestão da SST em empresas de referência, que o modelo proposto e disponibilizável por meio da internet, é exeqüível e de fácil aceitabilidade. Além disso, ele poder ser utilizado remotamente, apresenta simplicidade de uso, interface amigável e a possibilidade de comparar empresas semelhantes, sem fornecer dados de acidentes ou doenças ocupacionais, ou ainda informações que identifiquem claramente a unidade organizacional. / This thesis addresses the Maturity Evaluation, the Six Sigma methodology and the Occupational Health and Safety (OHS) Management system. The main goal of this thesis was to develop a model for the assessment of the OHS management system and corresponding improvement actions, sustained by concepts derived mainly from the Maturity Evaluation process and Six Sigma methodology. This goal was achieved through the review, analysis and classification of the relevant bibliographic references on the specific topics, the implementation of a survey and the construction of a model in view of the results of the survey, of the reviewed theoretical framework and of the interviews complemented by the corresponding content analysis. As a result of the literature review, it was possible to verify that there is a predominance of techniques focused on specific and isolated actions, aiming to implement some improvements in the area. In what concerns the Maturity Evaluation, it was identified that there is a predominance of models based on five maturity levels, that these models are typically structured by maturity grids, as well as that OHS maturity evaluation models are scarce. Some organizational characteristics, such as the existence of OHS internal services, existent management systems certifications, the activity sector or the quantity of subcontracted employees, have come to play a relevant role in distinguishing the organisational unit and the corresponding effort needed to change their performance level regarding the OSH management system. The identification of this organisational profile will aid in the differential evaluation and treatment of the problems or opportunities regarding management practices in particular. Taking into consideration the opinion of OHS managers from some reference companies, it was also demonstrated that the proposed model, which is available online, is feasible and easily acceptable. Furthermore, the model, which can be used at a distance, is easy to use, has a user-friendly interface and allows for the comparison of similar companies without needing to provide details regarding company records on accidents, professional diseases or other information that clearly identifies the organisational unit.

Towards data-driven decision making: A Small Enterprise studySöderlund, Oliver January 2022 (has links)
In general, at smaller companies, decisions are based on the intuition of their experts within their respective areas. The decision processes are dependent on several aspects, such as assumptions and context, and some on data. Over the last year, the increase in data flow has enabled SMEs to make a decision in a systematic and planned process referred to as data-driven decision-making(DDM). Small-medium enterprises (SME) companies have been affected by enabling aspects. However, research shows challenges for SMEs trying to develop their DDM. To address these challenges, this thesis aims to propose a process to assess and develop data-driven decision-making in an SME within the manufacturing industry. The study has been made with a qualitative approach. In addition, a case study of an SME within the manufacturing industry has been done to study the phenomenon in a real-life situation. The data collection was conducted by a literature review, interviews, and planned and unplanned observations. The literature review showed that different aspects affect the development of DDM. The aspects discussed were the decision-making process, technology and organisational factors such as general change, organisational culture, resistance to change, management and the last aspect, Data quality. A maturity assessment model was discussed to introduce the ability to assess a company's current state. The empirical data discussed two main aspects: the current state and the desired future state. The empirical findings showed that there were three main levels of decision-making in the current state: Operator level, Production level, and Management level. The desired state discusses data expectations, which provides a view of the company's perception of what data is and how it is used. In the analysis, there were two main challenging aspects identified from the empirical and theoretical data, and these were organisational and technological factors. The challenges related to technological factors were identified, such as digital adaptation, technological uncertainties and data quality. The challenges related to Organisational factors were the decision-making process, adaptation to change, organisational culture and data quality. Based on these challenges and the evaluation of the maturity model and application process, a different proposed application process was created to help organisations develop their DDM. Some of the challenges identified within the SME company connect to the challenges found in theory, and they bring future support that these challenges are present in real-life situations. An aspect that was identified as both a technological factor and an organization is the need for data quality and evaluation of it within the organisation. It shows that this is a critical aspect that must be considered when developing DDM.Keywords: Data-driven decision-making, Techno

Aplikace procesní analýzy při řízení kvality a testování software / Application of the process analysis in quality assurance and software testingPopelka, Vladimír January 2011 (has links)
This thesis deals with questions regarding quality assurance and software testing. The subject of its theoretical part is the specification of the general concept of quality, description of standards used in the field of software product quality evaluation and finally the evaluation of software development process itself. The thesis intends to introduce the theoretical framework of software quality assurance, especially the detailed analysis of the whole software testing branch. An added value to the theoretical part constitutes the characterization of procedural approach and selected methods used towards the improvement of processes. The practical part of the thesis comprises of the exemplification -- it shows the procedural approach at software quality management, applied to a selected IT company. The main aim of the practical part is to create a purposeful project for optimization of quality assurance and software testing processes. The core of the matter is to accomplish the process analysis of the present condition of software testing methodology. For the purpose of process analysis and optimization project, the models of key processes will be created; these processes will then be depicted based on defined pattern. The description of the state-of-the-art of software product quality assurance processes is further supplemented by the evaluation of such processes maturity. The project for optimization of software testing and quality assurance processes comes from the process analysis of the present condition of software testing methodology, as well as from the evaluation of procedural models maturity. The essence of processes optimization is the incorporation of change requests and innovative intentions of individual processes into the resulting state of methodology draft. For the measurement of selected quality assurance and software testing processes, the configuration of efficiency indicators and their application on particular processes is implemented. The research on the of the state-of-the-art, as well as the elaboration of this whole project for optimization of software testing and quality assurance processes runs in conformity with the principles of DMAIC model of Six Sigma method.
