Abstract
Purpose
Do managers at different hierarchical levels in a firm perceive the effectiveness of a lean program differently, and does it matter for their commitment to it and the resulting lean implementation? This study answers these questions by analyzing the perceptions and behaviors of top and middle managers in a manufacturer deploying a global lean program.
Design/methodology/approach
The authors hypothesize that managers at different levels perceive lean programs differently, which, in turn, should affect their commitment to lean and the resulting implementation. To test these relationships empirically, the authors collect survey data from a global manufacturer in the process industry and analyze them using hierarchical linear regression and structural equation modeling.
Findings
The findings show that middle managers perceive lean programs as more effective than top managers do. They further show that higher commitment from the top and middle managers to the lean program is positively related to building the organizational infrastructure needed for lean implementation.
Research limitations/implications
This research is conducted in one global company. Although the research setting implicitly controls for many possible confounding variables, such as the product and process complexity or organizational culture, future research can explore and test the findings in other organizational contexts.
Originality/value
This study is the first to empirically study the relations between perceptions of and commitment to lean programs across different hierarchical levels and what it means for program implementation. The paper contributes new plausible explanations for why many lean programs slow down.

Abstract
Purpose
The purpose of this study is to investigate how soft lean practices moderate the performance effects of hard lean practices. The authors provide new evidence from the pharmaceutical industry, which is characterized by a highly regulated and technical environment and has been largely uncharted in the lean literature.
Design/methodology/approach
Based on a review of the literature, the authors define a set of soft and hard lean practices. The authors test the hypotheses using factor analysis and moderated hierarchical linear regression on a unique dataset containing survey data and real performance measures of 351 pharmaceutical plants.
Findings
The results show that soft lean practices can be both enabling and constraining. When management engages in performance measurement, visualisation and employee empowerment the relationship between hard lean practices and performance is positively moderated. On the other hand, when managers emphasise goal setting and work standardisation the performance outcomes are reduced.
Practical implications
Effective lean managers build organisational commitment by motivating other employees to implement lean. They use performance measurement, visualisation and employee empowerment to focus on the “why”. Less effective managers engage in commanding and micro-management. Such managers focus on the “what” by using practices like goal setting and work standardisation.
Originality/value
This article contributes to the literature on lean management by empirically testing the moderator-variable interaction effects between soft and hard lean practices. In addition, it adds new evidence from the important pharmaceutical industry.
