Purpose

Top management commitment (TMC) and prosocial voice behaviour in Lean teams are vital for the successful Lean implementation. This study aims to investigate how TMC influences Lean team members’ prosocial voice behaviour and how such changed voice behaviour affects the outcome of Lean implementations.

Design/methodology/approach

The authors have used a qualitative research methodology to examine six dimensions of TMC (communication, involvement, support, empowerment, encouragement and monitoring) in two ready-made garment (RMG) factories in Bangladesh. Operational performance was measured by efficiency, quality, value stream mapping, single-minute exchange dies and 5S scores. Occupational Health and Safety (OHS) was assessed by acceptable head and back positions, machine safety, use of masks and housekeeping.

Findings

The findings reveal that TMC influences Lean team members' voice behaviour positively and, thereby, company's performance. Six dimensions of TMC are all critical for mobilizing prosocial voice, which then improves productivity, OHS and enhancing employee capacity and job satisfaction.

Research limitations/implications

This research involved two sewing lines in two RMG factories in Bangladesh. Cross-sector and large-scale international quantitative research is also needed.

Practical implications

This research shows how TMC and Lean problem-solving teams can mobilize employee voice.

Originality/value

Employee voice is a central issue in the implementation of Lean. To the best of the author’s knowledge, for the first time, the authors show how the six dimensions of TMC influence Lean team members’ voice behaviour in the workplace and thereby how prosocial voice affects team performance.

高层管理承诺和精益团队成员的亲社会发言行为

目的

精益团队中的高层管理承诺 (TMC) 和亲社会的声音行为对于成功实施精益至关重要。本研究旨在调查 TMC 如何影响精益团队成员的亲社会建言行为以及这种改变的建言行为如何影响精益实施的结果。

设计/方法/方法

作者使用定性研究方法在孟加拉国的两个成衣 (RMG) 工厂中检查了 TMC（沟通、参与、支持、授权、鼓励和监控）的六个维度。运营绩效通过效率、质量、价值流映射、单分钟交换模具和 5S 分数来衡量。职业健康与安全 (OHS) 通过可接受的头部和背部位置、机器安全、口罩的使用和家政进行评估。

发现

调查结果表明，TMC 对精益团队成员的建言行为产生积极影响，从而对公司绩效产生积极影响。TMC 的六个维度对于动员亲社会声音至关重要，进而提高生产力、职业健康安全和提高员工能力和工作满意度。

研究限制/影响

这项研究涉及孟加拉国两家 RMG 工厂的两条缝纫线。还需要跨部门和大规模的国际定量研究。

实际影响

这项研究展示了 TMC 和精益问题解决团队如何调动员工的声音。

原创性/价值

员工的声音是实施精益的核心问题。据作者所知，作者首次展示了 TMC 的六个维度如何影响精益团队成员在工作场所的建言行为以及亲社会建言如何影响团队绩效。
