The applications of Kaizen methods in project settings: applied study in Jordan

Effect of lean manufacturing tools on sustainability: the case of Mexican maquiladoras

The Mexican maquiladora industry is applying Lean Manufacturing Tools (LMT) in its production lines; however, few studies have investigated its relationship with sustainability (social, economic, and environmental). This paper presents a second-order structural equation model (SEM) relating 8 LMT integrated into three independent latent variables: continuous improvement (Kaizen and Gemba), supporting tools (Andon, visual management, and Poka-yoke), and machinery and equipment (total productive maintenance, overall equipment effectiveness, and Jidoka) that are related to social, economic, and environmental sustainability as dependent variables. The model is validated with information obtained from 249 companies using partial least squares. Findings show that the application of LMT in the Mexican maquiladora industry avoids the generation of waste and reprocessing. Likewise, the improvement of production processes reduces the waste emitted into the environment and reduces energy consumption. Also, when companies have environmental programs, the work environment is safe, and labor relations are improved, increasing morale and the commitment to work for the company, gaining economic and ecological benefits.

Integration of continuous improvement strategies with Industry 4.0: a systematic review and agenda for further research

Purpose

The purpose of this paper is to provide a review of the history, trends and needs of continuous improvement (CI) and Industry 4.0. Four strategies are reviewed, namely, Lean, Six Sigma, Kaizen and Sustainability.

Design/methodology/approach

Digitalization and CI practices contribute to a major transformation in industrial practices. There exists a need to amalgamate Industry 4.0 technologies with CI strategies to ensure significant benefits. A systematic literature review methodology has been followed to review CI strategy and Industry 4.0 papers (n = 92).

Findings

Various frameworks of Industry 4.0, their advantages and disadvantages were explored. A conceptual framework integrating CI strategies and Industry 4.0 is being presented in this paper.

Practical implications

The benefits and practical application of the developed framework has been presented.

Originality/value

The article is an attempt to review CI strategies with Industry 4.0. A conceptual framework for the integration is also being presented.
