Expert-Identified Practices for Achieving Measurable Performance Improvements With Lean Implementation

Abstract

Background and Objectives: 

Despite the rapid spread of Lean management in health care, few organizations have achieved measurable overall performance improvements with Lean. What differentiates these organizations from those that struggle with realizing the potential benefits of Lean management is unclear. In this qualitative study we explore measuring the impact of Lean and the recommended practices for achieving measurable performance improvements with Lean in health care organizations.

Methods: 

Informed by preliminary quantitative results from analyses of high- and low-performing Lean hospitals, we conducted 17 semi-structured interviews with Lean health care experts on the Lean principles and practices associated with better performance. We conducted qualitative content analyses of the interview transcripts based on grounded theory and linking to core principles and practices of the Lean management system.

Results: 

The qualitative data revealed 3 categories of metrics for measuring the impact of Lean: currently used institutional measures, measures tailored to Lean initiatives, and population-level measures. Leadership engagement/commitment and clear organizational focus/prioritization/alignment had the highest weighted averages of success factors. The lack of these 2 factors had the highest weighted averages of biggest barriers for achieving measurable performance improvements with Lean implementation.

Conclusions: 

Leadership engagement and organizational focus can facilitate achieving the organization's performance improvement goals, whereas their absence can considerably hinder performance improvement efforts. Many different approaches have been used to quantify the impact of Lean, but currently used institutional performance measures are preferred by the majority of Lean experts.
