Does lean implementation interact with group functioning?

Area of Science:

• Healthcare Management
• Organizational Psychology
• Process Improvement

Background:

• Healthcare Lean interventions often focus on operational efficiency, neglecting socio-technical aspects like teamwork.
• Understanding the impact of Lean on teamwork is crucial for successful healthcare improvement initiatives.

Purpose of the Study:

• To explore the relationship between a Swedish hospital Lean intervention and changes in teamwork over time.
• To assess how different levels of Lean implementation affect healthcare teamwork.

Main Methods:

• Utilized the Group Development Questionnaire (GDQ) for employee surveys at three hospital units (2010, 2011).
• Collected qualitative data (interviews, observations, document analysis) to contextualize Lean implementation.
• Employed linear regression analysis to compare expected teamwork changes with empirical GDQ data.

Main Results:

• Ward-I: Successful Lean implementation correlated with improved teamwork.
• Ward-II: Partial Lean implementation showed slight teamwork improvement.
• Emergency Department (ED): Both Lean implementation and teamwork deteriorated; regression analysis was significant (p=0.02 for ED, p=0.04 for Ward-II).

Conclusions:

• Lean's impact on teamwork is contingent on proper implementation, potentially affecting structural and productivity aspects more than relational ones.
• Initial group functioning significantly influences Lean implementation success in healthcare settings.
• Integrating theoretical expectations with qualitative and quantitative data aids in evaluating complex change interventions like Lean.
