Implementing and sustaining lean, buyer-supplier role, and COVID-19 pandemic: insights from the garment industry of Bangladesh

Abstract

Purpose

This study aims to explore the challenges in implementing and sustaining lean in garment supplier factories and the buyer–supplier role in mitigating lean barriers in a typical situation and pandemic.

Design/methodology/approach

Following a qualitative research approach and multiple embedded case study method, data were collected through in-depth interviews with senior managers of one lead buyer and their four key garment supplier factories in Bangladesh. Within and cross-case analysis, techniques were applied to understand the context-oriented lean challenges and buyer–supplier role in mitigating the challenges.

Findings

The study findings demonstrate that garment suppliers are less prepared and unsystematic in lean implementation having limited capabilities and less preparation. Moreover, they have limited support from buyers, less commitment from top management and employee resistance to implementing lean. Lean challenges become more intense because of the COVID-19 pandemic. However, buyer–supplier responsible, cooperative and collaborative behaviour can mitigate lean challenges.

Research limitations/implications

Whereas many stakeholders may be responsible for lean challenges, this study explores dyadic role between buyer and supplier only based on a single lead buyer and their four suppliers. Hence future studies could consider more buyers and suppliers for a holistic understanding.

Practical implications

This study could help buyers and suppliers understand the underlying causes of lean implementation challenges in garment supplier factories and their role in sustaining lean reducing the challenges, particularly in a pandemic.

Originality/value

To the best of the authors’ knowledge, for the first time, this study depicts how buyer and supplier can play their due roles to mitigate lean challenges in garment supplier factories in a pandemic situation.
