A process improvement approach based on the Value Stream Mapping and the Theory of Constraints Thinking Process

Title: A process improvement approach based on the Value Stream Mapping and the Theory of Constraints Thinking Process

Abstract: Purpose – The purpose of this paper is to present a case of integration between the processes modeling by using the Value Stream Mapping (VSM) and the Thinking Process of the Theory of Constraints (TP-TOC) through the analysis of productive processes of an organization, indicating the complementary aspects between them and their benefits to the organization.

Design/methodology/approach – The paper uses a company of the Brazilian automotive industry as the administering site. The research began by identifying the organization’s processes and choice of a family of products to model according to the VSM approach. The integrated view between the losses in the process (VSM) and the unwanted effects of the adding value process were analyzed by using the Current Reality Tree. After the analysis, different improvement procedures are proposed based on the lean principles. Finally, a work plan is presented based on the previous steps aiming to achieve the proposed future state.

Findings – The analysis of this case helps to understand and identify the causes of the current problems in the processes studied, providing an integrated view between the losses in the process and the prioritization of steps for the elimination of such losses. The approach in its initial administration was robust and the solution steps were promising. By integrating these approaches, it was possible to verify improvement opportunities by identifying the losses and the basic causes that sustain the unwanted effects in the processes at the same time.

Originality/value – The study proposes an approach that enables a systematic and systemic analysis of the processes at organizations through the combined use of process modeling through the VSM and TP-TOC. Simultaneously, the losses in the processes and the unwanted effects are identified. Thus, through the construction of an effect-cause-effect robust logic, both losses in particular and the unwanted effects in general can be prioritized in order to maximize the improvement efforts in the processes.

Supply Chain Management: a view from the Theory of Constraints

Title: Gestão da Cadeia de Suprimentos: uma reflexão a partir da Teoria das Restrições. (Supply Chain Management: a view from the Theory of Constraints).

Abstract: Among the various theoretical approaches of production systems, has excelled in entrepreneurial and academic discussions Theory of Constraints (TOC). Concomitantly expands and grows in importance, the discussions regarding Supply Chain Management (SCM). This is because the definition of strategies of Supply Chain (SC) can determine the viability of an operation. In this context, this paper proposes to conduct a theoretical reflection of SGM from the TOC. Within the environment of SCM four elements were chosen for this study: stock, transport, localization and logistic services that are analyzed by the proposals set out in the TOC, giving rise to a number of possibilities to be developed for the SCM. Finally this study summarizes the relationship built between the four elements and TOC, and presents possibilities for future applications derived from this work and its limitations.

Revealing factors affecting strategy implementation in HEIs - a case study in a Brazilian university

Title: Revealing factors affecting strategy implementation in HEIs - a case study in a Brazilian university.

Abstract: Studies of the problems of implementation report that a major portion of strategies are not implemented. While strategy implementation is itself a subject worthy of study, the implementation context poses specific challenges like higher education institutions (HEIs). The HEI context is one of heightened competition. Accordingly, this study investigates what factors influence the transformation of whatever strategic intentions exist into whatever strategic actions are taken. A case study was conducted at an HEI in southern Brazil. The study presents elements relating to factors that may influence processes leading to the implementation of strategic intentions. The study sought to contribute by providing a model that explicitates possible relationships among factors that impact implementation.

Exploring the Relationship Between Marketing and Operations: Neural Network Analysis of Marketing Decision Impacts on Delivery Performance

Title: Exploring the Relationship Between Marketing and Operations: Neural Network Analysis of Marketing Decision Impacts on Delivery Performance.

Abstract: This study has the objective of exploring the relationship between two functional areas: marketing and operations. This relationship has been the focus of attention of other scholars, but much remains to be done in terms of providing a better understanding of it. To help fill this gap, we analyze the impact of marketing decisions on delivery performance. More specifically, we seek to know how sales, sellers, promotion and other variables that characterize marketing decisions impact delivery performance. We collected data about marketing decisions and delivery performance for a period of 30 months in a large manufacturing company in Brazil. We performed an artificial neural network analysis to assess how these marketing decision variables impact delivery performance variables in the company analyzed. Results show that seller characteristics are the variables that have the greatest impact on the performance of delivery operations.

Flow balancing or capacity balancing? Systemic analysis and propositions

Title: Balanceamento de fluxo ou balanceamento de capacidade?: análises e proposições sistêmicas. (Flow balancing or capacity balancing? Systemic analysis and propositions)

Abstract: Manufacturing performance improvement can be achieved in several different ways. On the one hand, the search for high efficiency and maximized utilization in all system resources through balancing the capacity of productive resources, for example, is still a common practice in manufacturing companies. On the other hand, there are companies that adopt flow balancing practices in their production system, which promote high efficiency and utilization only in the restrictive resources of the system, the bottlenecks. Given these possibilities, the main objective of this paper is to evaluate the manufacturing implications and differences between flow balancing and capacity balancing. An analysis identifying the variables that are critical to this managerial decision making process was carried out. A literature review on this topic was conducted, and subsequently, the analysis was performed based on the System Thinking approach. This approach, among other things, allows the identification of effect-cause-effect relationships. The results obtained demonstrated points of convergence and divergence between these two views. It was found that adopting managerial decisions considering flow balancing combined with certain practices of capacity balancing can help increase the company overall gains.
