- Continuous improvement practice and the stages of service operations competitiveness: a hospital case study(2022-09-30) TEIXEIRA, A. L.; Dario Alliprandini; Claudia MattosCopyright © 2022 Inderscience Enterprises Ltd.This paper aims to study the relationship between the continuous improvement maturity level and the stages of service operations competitiveness, relating the abilities of each continuous improvement maturity level to the aspects that are inherent to each stage of service operations competitiveness in the hospital sector. This paper was developed by means of exploratory field research using a case study method in three hospitals. The findings of this study are innovative in the research field, as this research proposes a theoretical model that seeks to identify the relationship between service operations competitiveness and its continuous improvement maturity level. As implications, the results of this study suggest that hospitals that decided to implement continuous improvement programs have better capabilities to offer services that are more competitive and continuously improve their processes to serve their patients better.
- Organizational learning in the context of product development processing: a case study in an automotive company(2022-08-10) Dario Alliprandini; Gabriela Scur; Vilas Boas Viveiros Lopes A.P.; Wakatsuki M.M.© 2022, Emerald Publishing Limited.Purpose: This study identifies and analyzes practices related to declarative knowledge of organizational learning in the product development process (PDP) that uses the Stage-Gate (SG) system. Design/methodology/approach: The field research was conducted with a qualitative approach through a case study. The study object was a multinational company in the automotive sector that is highly competent in truck chassis design with a PDP based on the SG system. Findings: The authors identified PDPs associated with the elements of declarative knowledge of organizational learning in intra- and inter-development teams. Rather than merely being a checklist, each gate in the SG system has the potential to become a more effective and robust intra-team learning practice and promote inputs for continuous improvement in the process through its use as a checkpoint of the five elements of declarative knowledge during the development activities. Research limitations/implications: The case study was conducted in a multinational company in the automotive sector, whose business units are divided by competencies. The unit studied is a reference in truck chassis and is located in the State of São Paulo, Brazil. Practical implications: The research model presented can be used to evaluate how companies exploit their activities and practices to leverage organizational learning in PDP. That is, the model can be used as a diagnostic reference for declarative knowledge in companies that apply the SG system to manage PDP. Originality/value: The study focuses on a model of PDP analysis, aspects of organizational learning and declarative knowledge, in that the model it assists in the collection, distribution and use of information to the development team members with a view for products with greater innovation potential.
- Allocation of Improvement Strategies in a Flow Shop with Two Capacity Constrained Resources(2020-07-05) Marcel Utiyama; CORREIA, FERNANDA CAVEIRO; Dario AlliprandiniThe main goal of this paper is to identify the best strategy to allocate improvement programs in a flow shop with two capacity constrained resources. We collected data from a manufacturing company, and we used them to conduct a simulation with the System Dynamics-Factory Physics model. The main variables considered were the mean time between failures and the mean time to repair, and lead time was the output. Strategies used are mainly focused, distributed, and hybrid. Findings show the effect of the allocation of different improvement strategies on lead time reduction. We indicated that for the flow shop analyzed the focused strategies delivered the best results. When it is not possible to perform a large investment in the capacity-constrained resource, companies should use hybrid approaches. An important contribution is a hybrid approach, which is a new way of directing efforts of improvements. Results showed that both strategies, hybrid time to repair improvement and hybrid time between failures improvement, delivered better results compared to the respective distributed strategies.
- The impact of product variety on fill rate, inventory and sales performance in the consumer goods industry(2020-03-05) SANTOS, VICTOR; Sampaio, Mauro; Dario AlliprandiniThe impact of product variety decisions on fill rate, inventory and sales performance in a consumer goods company has been examined. From a marketing perspective, it is possible to leverage sales, reach new segments and consequently increase competitiveness when there is a greater product variety on the market. However, operations and logistics professionals indicate potential impacts on the supply chain, such as production, storage and distribution complexity. The nature of the product variety-cost-sales performance relationship is not clear, and empirical evidence about whether and how operations cost and sales performance increases with variety is inconclusive. Design/methodology/approach – The multiple linear regression and the Tobit regression techniques were applied over a seven-year horizon of data from a business intelligence platform of a consumer goods company. Findings – Our results show that sales performance is negatively associated with product variety. The total effect of product variety on sales performance has been examined, including both the direct effect and the indirect effect through inventory and fill rate. Therefore, the findings provide a comprehensive understanding of the impact of product variety on operations and sales performance. Originality/value – Several studies have researched the impact of product variety on fill rate, inventory and sales performance separately; however, the research of the impact and the relationship of these factors is scarce and limited.
- Environmental assessment in the conceptual design phase of new product development(2020-02-14) RUY, MARCELO; Dario Alliprandini; Gabriela ScurMany studies have shown the importance of incorporating environmental issues into the process of new product development (NPD). However, a critical review of the literature reveals a lack of tools to evaluate environmental criteria during the initial phases of product design - specifically, the conceptual design phase and concept selection stage. The objective of this manuscript is to present a framework for the environmental evaluation of product concepts based on design for environment (DfE), with an emphasis on tangible products. The framework could enhance the effectiveness of implementing DfE strategies in the conceptual design phase. The framework was based on DfE strategies related to the physical dimension of products and the analytical hierarchy process (AHP). This is one of the very first studies to present a framework for selecting a concept that best meets DfE criteria from a product life cycle perspective and offers the potential to be expanded to multiple manufacturers.
