Abstract

Purpose

Lean enterprise (LE) is one of the emerging fields because of its impact across industry sectors. There were many LE framework articles published in the past without reviewing or considering the already published literature which lead to lots of inconsistencies in the existing frameworks of LE. This study aims to critically review the existing frameworks to identify inconsistencies and propose a new LE framework to overcome limitations of the existing LE frameworks.

Design/methodology/approach

A systematic literature review was conducted to identify the existing LE frameworks. All these identified frameworks were classified based on the following criteria: novelty of the framework; based on participation of academicians/practitioners/consultants; whether the proposed frameworks were verified; type of verification methodology used; and the degree of standardization of LE elements. A comprehensive LE framework was proposed after a thorough review of the existing LE frameworks which has been validated through reliability analysis and validity analysis.

Findings

The analysis revealed major inconsistencies such as lack of adaptation of existing frameworks in literature which lead to incoherent elements in LE frameworks. The study also found shortage of significant participation of academicians and practitioners in LE frameworks development compared to consultants. The present work established a road map to find a “cohesive theory of LE”, which resulted in the development of a set of coherent elements. Finally, a comprehensive LE framework was proposed with the help of extensive literature review. The initially proposed 106 elements were condensed to 50 after the validation to increase the focus and relevance.

Research limitations/implications

The proposed LE framework needs to be validated via an empirical approach or clinical approach such as a case study which will be the future work.

Originality/value

The present study performed extensive literature review to identify LE-related articles, corresponding elements and established coherency among them. A new comprehensive framework was proposed.

Abstract

Purpose

There is a concern in literature about the critical elements of lean enterprise (LE) that can be represented as pillars of lean enterprise excellence. However, existing frameworks proposed on LE excellence are very few. The purpose of this paper is to develop a relationship model among the pillars of a proposed framework of LE excellence in Indian manufacturing industry by Jasti et al. (2020) with the help of interpretive structural modelling (ISM) and structural equation modelling (SEM).

Design/methodology/approach

The ISM is constructed on two exemplary cases of lean operations from two Indian manufacturing organisations. These cases were selected based on the implementation of lean practices in respective organisations. The two manufacturing organisations which implemented lean practices at different levels were selected as contenders for constructing ISM. The relationships among pillars and constructs of LE framework are obtained from ISM, and later subjected to statistical testing for model fit by using SEM. The input to SEM was the respondent's data collected in a previous study.

Findings

The outcome of the present study revealed that the successful implementation of LE framework requires an appropriate strategy along with top management commitment to get a complete benefits of LE. The study has proposed a strategy to implement the proposed LE framework in Indian manufacturing industry. This study has revealed that ISM developed based on the focal company that implemented lean practices effectively is statistically fit for LE framework.

Research limitations/implications

The study has established paired relationships among lean pillars for an effective implementation of LE framework. The investigation was started by collecting opinions of experts to perform the appropriate interpretations subsequently. However, the expert judgements can be qualitative in nature and prone to bias and impact the final outcome. To overcome these a large-scale empirical survey is suggested to provide a better catch for interactions in LEs.

Practical implications

This study helps in providing concrete practical implications to both academic researchers as well as industry professionals. The practitioners normally focus on finding readymade strategies for implementing LE in the organizations. The comprehensiveness of the present work helps the practitioners in implementing LE strategy with ease. The study revealed that management commitment and leadership is driving force but needs strategic implementation methodology for successful implementation.

Social implications

Manufacturing industries across the world have been struggling to understand and implement LE strategy effectively. Most of the governments across the world are supporting and motivating various industry practitioners to implement LE strategy by providing financial assistance for conducting training programmes. However, many organizations across the world were not able to implement LE strategy successfully. The present study provides a strategy to implement LE framework effectively in an organization.

Originality/value

The study offers a unique approach for analysing the underlying relationships among pillars of LE for effective management. Researchers can use the results of this study for developing frameworks in various domains of LE.

Abstract

Purpose

Lean manufacturing (LM) plays a major role in eliminating wastes (activities/resources) in a manufacturing organization. Value stream mapping (VSM) is one of the critical tools in LM which will help in identifying wastes in materials and information flow in a specific product family. The purpose of this paper is to illustrate the significance of VSM in the auto-ancillary industry in enhancing the productivity and the quality.

Design/methodology/approach

A case study approach is followed to demonstrate the significance of VSM in identifying various wastes in the auto-ancillary industry. The study has been performed by implementing seven critical steps. A product family is identified based on the customer demand and a cross functional team with specialized experts was formed. The overall processes with sequence are mapped using process flowchart. A cross functional team has been formed to develop the current state of VSM and perform a critical analysis to identify shortcomings. An investigation was performed to overcome the existing shortcomings by identifying opportunities. The relevant kaizens to improve the current state have been proposed. The cross functional team of experts have performed a feasibility study on implementation of proposed kaizens. Finally, a future state of VSM after implementation of feasible kaizens has been reported.

Findings

The results show that future state of VSM brings out the positive impact with respect to process ratio, TAKT time, process inventory level, total lead time and bottleneck time. The proposed improvement also helped to achieve higher customer satisfaction in terms of increased quality, reduced cost and on time delivery.

Research limitations/implications

Present study is focussed on a single product family cell in one of the auto-component organization.

Originality/value

Helps practitioners in the auto-component industry to implement the VSM effectively in their organization.

Abstract

Purpose

Supply chain management plays a vital role in deciding the final cost of products. A huge number of non-value-added activities are performed throughout supply chain process. Lean principles are useful to identify and eliminate waste activities across the supply chain management processes. The purpose of this paper is to examine the validity and reliability of the existing lean supply chain management (LSCM) frameworks in the Indian manufacturing industry through questionnaire survey methodology.

Design/methodology/approach

The present study collected empirical data from 180 top- and middle-level management personnel from the Indian manufacturing industry. Factor analysis was performed to check unidimensionality of LSCM frameworks by using empirical data. Cronbach’s α value of each selected LSCM framework was calculated to find out its reliability. Finally, frequency distribution analysis was performed on the selected framework to identify and reveal critical constructs of LSCM.

Findings

It was found that nine LSCM frameworks show unidimensionality. The study established that most of the selected frameworks exposed a high level of reliability. The frequency distribution analysis revealed that the larger part of the constructs had a high mean score and mode. It is concluded that there is a need for a new LSCM framework to fulfill the requirements of the Indian manufacturing industry.

Originality/value

The present study is focused on checking the suitability of existing LSCM frameworks in the Indian manufacturing sector. It is anticipated that the study will be helpful to the professionals who wish to execute appropriate LSCM framework in the manufacturing organization.

Abstract

Purpose

This paper aims to investigate the impact of simulation laboratory on continuing education engineering students’ academic performance.

Design/methodology/approach

The investigation consists of establishing the student learning levels then mapping the student learning levels (knowledge, comprehension, application, analysis, synthesis and evaluation) through program outcomes with appropriate evaluation components. 270 continuing education students enrolled during six years were selected to be observed as part of this study. These students were divided into two subgroups, one with 135 students who were offered simulation lab (G2) and the other 135 students were not offered simulation lab (G1) in this investigation. Subsequently, a comparative analysis was carried out on these two groups to assess the student performance in multiple evaluation components with respect to student learning level and program outcome achievement.

Findings

It was identified that student performance in the application, analysis, synthesis and evaluation learning levels has improved for the group with simulation lab, and no change or minimal change was observed for the group without simulation lab. It was revealed that the simulation lab practice problems needs to be aligned with the theoretical concepts in the course to get a better performance from the students.

Originality/value

The study was conducted in one of the leading institutes with 270 students’ performance observed over a period of six years. It is the comprehensive work done on a complete program with data collated over a period of six years in multiple courses and multiple assessments.

Abstract

Purpose

The purpose of this paper is to investigate, validity and reliability analysis on existing Lean manufacturing (LM) frameworks when applied to Indian organizations. LM is one of the best manufacturing strategies that are used by manufacturing plant managers to improve manufacturing capabilities.

Design/methodology/approach

In the present research work, a questionnaire-based survey was used to examine 35 LM frameworks. The study targeted respondents ranging from top- and middle-level management personnel in Indian manufacturing industry. The sample includes organizations in a variety of industries ranging from automobile, electronics, engineering, process and textile industries products. The survey tool was prepared with team of 12 members i.e. six academicians and six professionals from manufacturing industry environment. The study received 186 responses from various sectors of manufacturing industry, 180 surveys were usable resulting in a response rate of 23.90 per cent. Factor analysis was conducted to check unidimentionality of the framework. Cronbach’s alpha is calculated to find reliability of each framework’s. Lastly, frequency analysis was used to recognize familiar constructs of LM on the chosen framework.

Findings

This study has identified that most of the LM frameworks revealed a high level of reliability. When the study has examined further advance about unidimensionality with respect to the construct, i.e. the LM it measures, it confirmed 11 frameworks were revealing unidimensionality. The frequency analysis was evident that a greater part of the constructs has a high mean score and mode. Finally, the research concludes that there is requirement for a novel framework to Indian manufacturing industry to stay in competition with global manufacturing industries.

Research limitations/implications

Cross-sectional data from manufacturing industries and India (only one country) is used with sample size restricted to 180 only, and it would be interesting to test these frameworks for more than one industry sector and country.

Practical implications

The present work tries to find the suitability of the presented LM frameworks to Indian manufacturing industry sector. The authors hoped that the present research would give the information to the management to execute the suitable LM framework in their firm.
