This research develops a model of relationships among components of Total-JIT, including JIT-information, JIT-manufacturing, JIT-purchasing, and JIT-selling, to establish an implementation hierarchy ...based on relative importance. The data collected relates to the relationships among JIT components and two performance measures, supply chain competency and organizational performance. Two groups are used in the research, one group of five operations management academics and another group of 30 practicing operations managers working in U.S. manufacturing firms. An interpretive structural modelling methodology is used to develop alternative structural models. The academics' data show JIT-information emerging as lynchpin of relationships, directly impacting all other JIT practices and both performance measures. The practitioners' data indicates that all JIT practices and performance measures are interactive as components and outcomes. This study is the first to apply interpretive structural modelling to investigate the interplay among total-JIT components and the performance measures of supply chain competency and organizational performance.
Total JIT (T-JIT) is defined as an integrated supply chain strategy incorporating previously defined elements of JIT-production, JIT-purchasing, JIT-selling, with the addition of an important new ...element, JIT-information. It would be interesting and informative to discover the extended concept's effect on supply chain competency and organizational performance. Here we examine the impact of a T-JIT strategy within a supply chain context, and analyze a model incorporating T-JIT as the focal construct with supply chain management strategy (SCMS) as an antecedent and supply chain competency (SCC) and organizational performance as consequences. Data from manufacturing managers were collected and the model assessed using a structural equation modeling methodology. Study results indicate significant, positive relationships between a supply chain management strategy and T-JIT, T-JIT and supply chain competency, and supply chain competency and organizational performance. The hypothesized relationship between T-JIT and organizational performance was not supported; however. This research is among the first to examine the impact of a T-JIT strategy within a supply chain context. The results of this study support T-JIT as a viable supply chain strategy that influences overall supply chain competency, contributing to organizational performance. In addition the definition of total system JIT and a scale for its measure is developed.
•We analyzed the impact of a Total JIT (T-JIT) strategy with a supply chain context.•We collected data and assess the model using structural equation modeling.•Positive and significant relationships among supply chain strategy, T-JIT, supply chain competency and organizational performance were found.•T-JIT was found to be a viable supply chain strategy that influences overall supply chain competency.
Evidence suggests that lean methods and tools have helped manufacturing organisations to achieve operational excellence, and in this way meet both traditional and contemporary organisational ...objectives such as profitability, efficiency, responsiveness, quality, and customer satisfaction. However, the effect of these methods and tools on environmental performance is still unclear, as limited empirical research has been conducted in this field. This paper therefore investigates the impact of five essential lean methods, i.e. JIT, autonomation, kaizen/continuous improvement, total productive maintenance (TPM) and value stream mapping (VSM), on four commonly utilised measures for the compliance of environmental performance, i.e. material use, energy consumption, non-product output, and pollutant releases. A correlation analysis modelled the relationship and effect of these lean methods on the environmental performance of 250 manufacturing organisations around the world. Structural equation modelling (SEM) was used as a second pronged verification approach to ensure the validity of the results. The results indicate that TMP and JIT have the strongest significance on environmental performance, whereas kaizen/continuous improvement only showed an effect on the use of materials and release of pollutants. Autonomation and VSM did not show any impact on environmental performance. The research holds important implications for industrialists, who can develop a richer knowledge on the relationship between lean and green. This will help them formulate more effective strategies for their simultaneous or sequential implementation. The paper extends our knowledge in the lean and green field by helping us to establish and explain the given relationships between five of the most important and commonly used lean methods and the environmental performance of manufacturing organisations. No previous research had considered the studied lean methods and environmental measures of performance.
•Five lean methods' effect on four measures of environmental performance is explored.•Correlation and SEM analyses from 250 companies were conducted.•TMP and JIT had the strongest significance on environmental performance.•Kaizen/CI only showed an effect on the use of materials and release of pollutants.•Autonomation and VSM did not show any impact on environmental performance.
The research analyzes the particularities of the Mexican maquiladora industry in the Just in Time (JIT) implementation process as a global example of maquiladoras, analyzing 31 competitive advantages ...or benefits obtained after a JIT implementation process, which were integrated into four dimensions:
Human Resources
,
Production Process
,
Inventory Management
, and
Economic Performance
of companies. The study proposes a structural equation model which assumes that human factor is the most important benefit obtained after JIT implementation and is proposed as the initial or independent latent variable, being the final latent variable or last benefits the company’s
Economic Performance
. The final results in the model show how the capabilities and skills in
Human Resources
affect 86 % of the variance of the
Production Process
, which together explains the 82 % of
Inventory Management
. Finally,
Human Resources
,
Production Process
, and
Inventory Management
explain 79 % of
Economic Performance
obtained from JIT.
La gestión de inventarios es un tema común cuando se estudia la gestión empresarial como elemento clave para optimizar el costo de operación de cualquier proceso productivo y/o prestación de ...servicio. Los modelos de inventarios tradicionales abordan la optimización de los niveles de inventarios para una organización individual, sin importar la relación de ésta, con el resto de la cadena de suministro de la que forma parte. En este aspecto, en la gestión empresarial la satisfacción del cliente final se logra mediante el cumplimiento de los flujos básicos de la cadena de suministros, de manera que se requieren niveles de cooperación e integración entre los participantes de la cadena en términos de inventario, con el objetivo de disminuir las pérdidas para cada parte y las mejoras en los costos totales de operación de sus sistemas de gestión. En este trabajo se estudia la optimización de los inventarios con un enfoque colaborativo, en empresas de servicios, mediante una visión justo a tiempo, de manera conjunta comprador-intermediario-proveedor. Se hicieron comparaciones con métodos tradicionales y se determinaron las ventajas de este enfoque colaborativo en los costos de inventario de la cadena de suministro y su incidencia en la satisfacción del consumidor final, a través de un caso de estudio.
