It has a fundamental role that is to translate the business strategy to the operations by developing the capabilities that are needed by the company in order to accomplish the desired performance. More precisely, manufacturing strategy comprises the decisions that managers take during a certain period of time in order to achieve a desire result. These decisions are related to which operational practices and resources are implemented. Our goal was to identify the relationship between these two decisions with operational performance. We based our arguments on the resource-based view for identifying sources of competitive advantage. Hence, we argued that operational practices and resources affect positively the operational performances. Additionally, we proposed that in the presence of some resources the implementation of operational practices would lead to a greater performance. We used previous scales for measuring operational practices and performance, and developed new constructs for resources. The data used is part of the High Performance Manufacturing project and the sample is composed by 291 plants. Through confirmatory factor analysis and multiple regressions we found that operational practices to a certain extant are positively related to operational performance. More specifically, the results show that JIT and customer orientation practices have a positive relationship with quality, delivery, flexibility, and cost performances. Moreover, we found that resources like technology and people explain a great variance of operational performance.

However, the literature of operations management provides inadequate constitutive definitions of operational capabilities, does not cover the relativization to different contexts, has limited empirical grounding, and does not adequately explores the more extensive empirical literature on operational practices. When practices are operationalized in the internal environment of the firm, they can be incorporated as organizational routines, and through the pre-existing tacit knowledge of production, become operational capabilities, thus creating barriers to imitation. But, a few scholars have explored operational practices as an antecedent of operational capabilities. Based on this review, we investigated about nature of operational capability; the relationship between operational practices and operational capabilities; types of operational capabilities characterized in the firm’s internal environment; and the impact of the operational capabilities on operational performance. Therefore, we conduct a mixed methods research. In qualitative stage, we conducted case studies in four firms, two multinational American firms operating in Brazil and two local Brazilian firms. We collected data through semi-structured interviews with open-ended questions, based on our theoretical review of operational practices and operational capabilities. The interviews were conducted face-to-face. In total, 73 interviews were performed in four different firms (21 - first case, 18 - second case, 18 - third case, 16 – fourth case). All interviews were recorded and transcribed literally in NVivo software. In quantitative stage, the sample was composed of 206 firms. The questionnaire creation involved an extensive review of the literature and also the use of the results of the analysis of the qualitative phase data. Q-sort was performed. Pre-test was administered to production managers. Measures were conducted to reduce Common Method Variance. A total of ten scales were used: 1) Continuous Improvement; 2) Information Management; 3) Learning; 4) Customer Support; 5) Innovation; 6) Operational Efficiency; 7) Flexibility; 8) Customization; 9) Supply Management; and 10) Operational Performance. We use Confirmatory Factor Analysis to conducted reliability, content, convergent, and discriminant validity. The data were analyzed using regressions. Our main results were: First, relate the operational practices as an antecedent of operational capabilities. Second, the creation of a typology divided into two constructs. The first construct is called Standalone Capabilities. This group consists of zero order capabilities such as Customer Support, Innovation, Operational Efficiency, Flexibility, Customization, and Supply Management. These capabilities aim to improve operational processes of the firm. They have a direct relationship with operational performance. Second construct is called Across-the-Board Capabilities. It is composed of first order capabilities such as Learning, Continuous Improvement, and Information Management. These capabilities are considered dynamic and they have the role to reconfigure Standalone Capabilities. / Operational capabilities são caracterizadas como um recurso interno da firma e fonte de vantagem competitiva. Porém, a literatura de estratégia de operações fornece uma definição constitutiva inadequada para as operational capabilities, desconsiderando a relativização dos diferentes contextos, a limitação da base empírica, e não explorando adequadamente a extensa literatura sobre práticas operacionais. Quando as práticas operacionais são operacionalizadas no ambiente interno da firma, elas podem ser incorporadas as rotinas organizacionais, e através do conhecimento tácito da produção se transformar em operational capabilities, criando assim barreiras à imitação. Apesar disso, poucos são os pesquisadores que exploram as práticas operacionais como antecedentes das operational capabilities. Baseado na revisão da literatura, nós investigamos a natureza das operational capabilities; a relação entre práticas operacionais e operational capabilities; os tipos de operational capabilities que são caracterizadas no ambiente interno da firma; e o impacto das operational capabilities no desempenho operacional. Nós conduzimos uma pesquisa de método misto. Na etapa qualitativa, nós conduzimos estudos de casos múltiplos com quatro firmas, duas multinacionais americanas que operam no Brasil, e duas firmas brasileiras. Nós coletamos os dados através de entrevistas semi-estruturadas com questões semi-abertas. Elas foram baseadas na revisão da literatura sobre práticas operacionais e operational capabilities. As entrevistas foram conduzidas pessoalmente. No total 73 entrevistas foram realizadas (21 no primeiro caso, 18 no segundo caso, 18 no terceiro caso, e 16 no quarto caso). Todas as entrevistas foram gravadas e transcritas literalmente. Nós usamos o sotware NVivo. Na etapa quantitativa, nossa amostra foi composta por 206 firmas. O questionário foi criado a partir de uma extensa revisão da literatura e também a partir dos resultados da fase qualitativa. O método Q-sort foi realizado. Um pré-teste foi conduzido com gerentes de produção. Foram realizadas medidas para reduzir Variância de Método Comum. No total dez escalas foram utilizadas. 1) Melhoria Contínua; 2) Gerenciamento da Informação; 3) Aprendizagem; 4) Suporte ao Cliente; 5) Inovação; 6) Eficiência Operacional; 7) Flexibilidade; 8) Customização; 9) Gerenciamento dos Fornecedores; e 10) Desempenho Operacional. Nós usamos análise fatorial confirmatória para confirmar a validade de confiabilidade, conteúdo, convergente, e discriminante. Os dados foram analisados com o uso de regressões múltiplas. Nossos principais resultados foram: Primeiro, a relação das práticas operacionais como antecedentes das operational capabilities. Segundo, a criação de uma tipologia dividida em dois construtos. O primeiro construto foi chamado de Standalone Capabilities. O grupo consiste de zero order capabilities tais como Suporte ao Cliente, Inovação, Eficiência Operacional, Flexibilidade, e Gerenciamento dos Fornecedores. Estas operational capabilities têm por objetivo melhorar os processos da firma. Elas têm uma relação direta com desempenho operacional. O segundo construto foi chamado de Across-the-Board Capabilities. Ele é composto por first order capabilities tais como Aprendizagem Contínua e Gerenciamento da Informação. Estas operational capabilities são consideradas dinâmicas e possuem o papel de reconfigurar as Standalone Capabilities.

Internal Control Strategies to Mitigate Fraud in Small Manufacturing Businesses in Cameroon

Molungu, Thomas Ndive 01 January 2019 (has links)
Approximately 51.3% of small manufacturing businesses lack effective internal controls to deter fraud. Internal control strategies, when adequately implemented, can mitigate fraud and improve profitability in small manufacturing businesses. The objective of this single qualitative case study was to explore the internal control strategies used in a small manufacturing business to mitigate assets misappropriation fraud and improve profitability. Agency theory was the conceptual framework for this study. Five business managers in a small manufacturing firm in Cameroon participated in face-to-face semistructured interviews. The data analysis process included Yin's 5-step process. Identified themes included (a) governance at a higher management level, (b) vendor-related management approach, and (c) operational practices at the department level. Business leaders in small manufacturing firms could benefit from implementing the internal controls and procedures highlighted in this study to deter fraudulent billing from vendors, deceitful payment disbursement to vendors, and misrepresentation of financial statements by company executives. Fraud reduction might help business leaders to safeguard the company's assets and improve production goals by streamlining operational practices, leading to company profitability. In turn, business profitability would result in company leaders paying more taxes, which government officials may use for social amenities and change benefiting people in the community.

Práticas de estratégias de fim de vida focadas no processo de desenvolvimento de produtos e suas aplicações em empresas que realizam a recuperação de produtos pós-consumo / Practices of end of life strategies with focus in the product development process and applications to companies that perform the recovery of post-consumer products

Saavedra, Yovana Maria Barrera 21 September 2010 (has links)
A recuperação de produtos por meio das estratégias de fim de vida (EoL) é uma alternativa pró-ativa que visa diminuir os impactos ambientais e os resíduos decorrentes do descarte desses produtos. O objetivo deste trabalho é levantar as práticas ligadas às estratégias de fim de vida que podem auxiliar o processo de desenvolvimento de produtos (PDP) e verificar quais estão sendo aplicadas por algumas empresas que recuperam produtos na fase de pósconsumo. Para tanto, foi realizada uma revisão bibliográfica sistemática que identificou 87 práticas de estratégias de fim de vida e 64 práticas operacionais que podem ser usadas na integração da recuperação de produtos no PDP. De modo a verificar a aplicação das práticas operacionais, foram realizados quatro estudos de caso em empresas reconhecidas pela sua excelência em processos de remanufatura. Os resultados da pesquisa permitem verificar a baixa aplicação de práticas operacionais dentro dessas empresas no processo de desenvolvimento de produtos. Nos casos em que elas foram implantadas, observou-se que elas são uma mera conseqüência da melhoria continua dos processos. No entanto, as empresas já percebem a importância dessas práticas operacionais para a melhoria da gestão do ciclo de vida de seus produtos e das oportunidades relacionadas com os pilares da sustentabilidade (ambiental, econômico e social). Finalmente, conclui-se que há um paradoxo entre a teoria e a aplicação nas empresas com relação às práticas operacionais de fim de vida do produto, desde o PDP. Isto é ratificado pelo grande número de práticas existentes na literatura quando comparadas com a aplicação destas práticas operacionais nas empresas estudadas. / The recovery of products using end-of-life strategies (EoL) is a proactive alternative that aims to diminish environmental impacts and waste generated from the disposal of products. This research aims to compile practices based on the EoL strategy that are used by companies in the (PDP). Focus is given to companies that recover products after they have been disposed. To this end, a literature review was carried out, in which 87 EoL-like practices were identified. Additionally, this research identified 64 operational practices that integrate the PDP process with the recovery of products. Four case studies were conducted in companies renowned for their excellence in remanufacturing to assess the applicability of EoL-like practices. It was found a low degree of adoption of such practices in the companies researched, mainly in the PDP process. The practices implemented were a mere implication of the continuous improvement of processes. Nonetheless, it was observed that these companies realize the importance of EoL practices to improve the life-cycle management of their products, which may positively impact all facets of sustainability (environmental, economical and social). Finally, we conclude that there is a gap between theory and practice with respect to EoL practices used in the product development process, which is supported by the great variety of practices found in the literature as opposed to the use of operational practices in the companies studied.

Proposta de boas práticas de operação que colaborem para a eficiência técnica das usinas de açúcar e etanol / Proposal of good operating practices that contribute to the technical efficiency of sugar cane and ethanol mills

Alexandre de Castro Moura Duarte 25 August 2017 (has links)
A cadeia produtiva do setor sucroenergético é de grande importância para o desenvolvimento do país, chegando a representar quase 2% do PIB. Uma importante contribuição do setor sucroenergético para a economia brasileira atual é relativa à produção de energia renovável. Na matriz energética primária do Brasil, a energia renovável participa com uma importante parcela de 46,9% comparado com 6,1% que os países participantes da Organização para a Cooperação e Desenvolvimento Econômico (OCDE) consomem, e ainda, é maior que a parcela de energia renovável consumida no mundo (13,2%). Do total de 46,9% da energia consumida brasileira, 18,8% é derivada da cana-de-açúcar, seguida por 13,9% de energia hidrelétrica e 10,2% de carvão. O aumento da eficiência técnica é um relevante fator para a competitividade do setor e, apesar de o Brasil ocupar uma posição de destaque na produção de bioenergia, as usinas de açúcar e etanol vêm enfrentando uma grave crise, culminando com uma retração da produção e o fechamento de diversas plantas industriais. A eficiência técnica industrial é o principal indicador de desempenho de uma usina de açúcar e etanol, podendo ser traduzida como a porcentagem dos açúcares da cana que são recuperados e transformados em açúcar, etanol e outros produtos. Desta forma, dada a crise atual do setor, do aumento da concorrência e da otimização da produtividade, as unidades produtivas necessitam aumentar sua eficiência em relação ao uso de insumos. Com o intuito de contribuir para a melhoria da eficiência e competitividades das usinas de açúcar e etanol, definiu-se como objetivo geral desta tese a proposta de boas práticas de operação que colaborem para o aumento eficiência técnica das usinas. Para tanto, os procedimentos metodológicos utilizados envolveram uma abordagem quantitativa e qualitativa. Na primeira etapa, foi utilizada a técnica Análise Envoltória de Dados (DEA), em conjunto com a análise de quintil e regressão multilinear truncada, para que fosse possível realizar uma análise das informações oriundas da base de dados utilizada e fornecida por uma empresa da região de Piracicaba. Em um segundo momento, foi realizado um estudo de caso em uma usina tida como eficiente na região de Ribeirão Preto, no estado de São Paulo, e uma entrevista com dois especialistas em processos de produção de açúcar e etanol visando entender o porquê de determinadas usinas serem mais eficientes do que outras. Por fim, as informações advindas de ambas as etapas foram cruzadas e analisadas, chegando-se à proposta de boas práticas operacionais, que provavelmente podem gerar aumento da eficiência técnica e, consequentemente, ganhos de competitividade às usinas de açúcar e etanol. / The productive chain of the sugar-energy sector is of great importance to the development of the country, reaching almost 2% of PIB. An important contribution of the sugar-energy sector to the current Brazilian economy is relative to the production of renewable energy. In Brazil\'s primary energy matrix, renewable energy accounts for an important 46.9% share compared to 6.1% that the OCDE countries consume, and is even larger than the share of renewable energy consumed in the world (13.2%). Of the 46.9% of Brazilian energy consumed, 18.8% is derived from sugarcane, followed by 13.9% hydroelectric power and 10.2% coal. The increase in technical efficiency is a relevant factor for the competitiveness of the sector and, although Brazil occupies a prominent position in the production of bioenergy, the sugar and ethanol mills have been facing a crisis culminating with a retraction of the production and the closing of several industrial plants. Industrial technical efficiency is the main performance indicator of a sugar and ethanol plant, and can be translated as the percentage of cane sugar that is recovered and processed into sugar, ethanol and other products. Thus, given the current crisis of the sector, increased competition and optimization of productivity, productive units need to increase their efficiency in relation to the use of inputs. In order to contribute to the improvement of the efficiency and competitiveness of the sugar and ethanol plants, the general objective of this thesis was to propose a good operating practice that will contribute to increase the technical efficiency of the plants. To that end, the methodological procedures used involved a quantitative and qualitative approach. In the first step, the Data Envelopment Analysis (DEA) technique was used, together with the quintile analysis and truncated multilinear regression, so that it was possible to perform an analysis of the information from the database used and provided by a company in the region of Piracicaba. In a second moment, a case study was carried out at a mill considered efficient in the region of Ribeirão Preto, state of São Paulo, and an interview with two experts on sugar and ethanol production processes aimed at understanding why certain plants are more efficient than others. Finally, the information from both stages was cross-referenced and analyzed, leading to the proposal of good operational practices, which are likely to increase technical efficiency and consequently increase competitiveness in the sugar and ethanol plants.
