Über dieses Buch

This book reports the elements required for implementing Just in Time (JIT) technique in companies. The main reasons for low implementation processes and the main benefits from the successful implementation of them are highlighted in this book. Structural equation models are presented to help identify the essential elements in JIT.

General Overview

Frontmatter

Chapter 1. Concepts of Just-in-Time (JIT)

Abstract
Just-in-Time (JIT) is a technique widely used in lean manufacturing environments, and since its conception a few decades ago, it has been extensively applied to support lean objectives. The aim of this chapter is to introduce readers to the historical evolution of JIT, its main concepts and principles, and how it has been successfully used with other techniques and methodologies to provide effective solutions for waste and lack of productivity problems.

JIT Elements, Its Benefits, and Causes of Its Slow Implementation

Frontmatter

Chapter 2. Elements of JIT

Abstract
The aim of this book is to identify the key elements that ensure the success of JIT, the benefits that companies obtain, and the causes of its slow implementation or abandonment. In addition, this book integrates these elements in causal models and associates those JIT elements identified with the benefits that companies obtain and the causes of a slow progress in its implementation. These models could allow managers and administrators to identify the elements that are essential for the success of JIT and those that cause great delay of the expected benefits. Thus, to achieve this, all crucial elements of JIT philosophy are first defined, along with the causes of a slow JIT implementation and the benefits. Once these elements were identified and discussed, the structural models were proposed.

Chapter 3. Benefits of JIT

Abstract
Companies implement JIT philosophy in order to obtain something in return, since these manufacturing and service companies aim to generate economic benefits. Therefore, if JIT cannot offer any of these benefits, they simply suspend its implementation.
Jorge Luis García-Alcaraz, Aidé Aracely Maldonado-Macías

Chapter 4. Causes of Slow Implementation of JIT

Abstract
Implementing JIT in a production system may not always be straightforward, and disappointing situations for managers and stakeholders can frequently arise, such as an early abandonment of the technique, its slow implementation, or the absence of convincing results that do not match with those reported in the literature. However, information regarding JIT benefits could often be misinterpreted, since the literature addresses them in different contexts. On the other hand, the literature approaching problems and errors associated with JIT implementation process is not equally disseminated.

Methodology

Frontmatter

Chapter 5. Research Methodology

Abstract
This chapter proposes a methodology for the models that will relate the identified JIT elements and causes of its slow implementation with the benefits obtained by the companies surveyed. This relation could allow managers and administrators to identify the elements that are keys to the success of JIT, as well as those that cause its slow implementation. The methodology here proposed was divided into several stages and combines several techniques widely used in multivariate analyzes.

Descriptive Analysis

Chapter 6. Descriptive Analysis of the Sample

Abstract
This chapter discusses a descriptive analysis related to the three objects of study: the elements of JIT, the benefits obtained after its successful implementation, and the causes of its slow implementation. A questionnaire for data collection was administered and validated in order to become familiar with the status of this lean manufacturing tool in the Mexican maquiladora sector. While this process of data collection and validation was explained in the methodology section of the previous chapter, the objective of this chapter is to characterize the sample following descriptive methods of research.

Chapter 7. Descriptive Analysis of the Elements of JIT

Abstract
This third part of the book provides a descriptive analysis for every of the three objects of study: JIT elements, the benefits obtained after its successful implementation, and causes of its slow implementation. More specifically, this chapter introduces the descriptive analysis for the elements that several authors point out as essential or indispensable for the success of JIT.

Chapter 8. Descriptive Analysis of JIT Benefits

Abstract
This chapter analyzes the benefits that can be obtained from a successful JIT implementation. Since data was obtained from subjective assessments, the median values were considered the measure of central tendency, while the measure of dispersion was represented by the interquartile range value and not by the traditional standard deviation used for interval values.
Jorge Luis García-Alcaraz, Aidé Aracely Maldonado-Macías

Chapter 9. Descriptive Analysis of the Causes of Slow JIT Implementation

Abstract
As mentioned in Chap. 4, companies can experience different situations that may lead to slow implementation of the JIT philosophy, and which in a critical condition could lead to its definite abandonment.
Jorge Luis García-Alcaraz, Aidé Aracely Maldonado-Macías

Structural Equation Models

Chapter 10. Causal Models of JIT Elements Associated with Human Resources and Obtained Benefits

Abstract
This chapter introduces three structural equation models that associate JIT elements previously reported concerning human resources with the benefits also previously reported. Readers may refer to methodology addressed in Chap. 5 for a full comprehension of the procedures here described concerning the planning, development, and execution of models.
Jorge Luis García-Alcaraz, Aidé Aracely Maldonado-Macías

Chapter 11. Causal Models of JIT Elements Associated with Production Process and the Obtained Benefits

Abstract
This chapter addresses three models to associate JIT elements from production process with JIT benefits obtained. Readers may once more refer to methodology addressed in Chap. 5 for a full comprehension of the procedures here described concerning the planning, development, and execution of models. Moreover, since the category of JIT elements associated with the production process comprises 18 items required for the successful JIT production process, it was necessary to perform a factor analysis to identify how many latent variables were comprised in this category.
Jorge Luis García-Alcaraz, Aidé Aracely Maldonado-Macías

Chapter 12. Causal Models JIT Elements Associated with Product and Obtained Benefits

Abstract
This chapter introduces two structural equation models to assess the impact of JIT elements related to the final product over JIT benefits obtained. The 13 items or JIT elements associated with the product were comprised into two major categories by means of a factor analysis, which will be described below. This factor analysis distributed all items into the two categories or also called latent variables or factors. These latent variables were named and will be proposed and tested in these models. Finally, readers can consult the methodology addressed in Chap. 5 and the previous chapters for a full comprehension of procedures concerning the evaluation and interpretation of these models.

Chapter 13. Causal Models of JIT Elements and Causes of Slow JIT Implementation

Abstract
Companies frequently report a number of problems when implementing Just-in-Time (JIT) philosophy in their production systems. Literature review in this book indicated that these issues are often due to the absence of an element that is required for the successful functioning of the philosophy. Thus, the absence of these elements is what causes that companies experience a slow progress in the implementation of a JIT system.
