Purpose: The aim of this research is to examine how lean has been implemented at geriatric care in a municipal department in Sweden, focusing on the experiences and challenges of the employees, together with the strengths and weaknesses of the lean philosophy. Design/methodology/approach: The primary method used was a case study with interviews and observations on spot, in combination with a literature study. All with the intention of defining and describing lean, its value, and how organizations generally apply lean. Findings: All sources of information have shown that there are many advantages with lean such as better communication and a better-organized workplace. In addition, lean tools help to eliminate non-value adding activities (waste). However, implementations also bring about issues and challenges such as the difficulty of creating a long lasting lean commitment. A lack of follow-ups and the decreasing demand for lean from the executives have been the main issues within the geriatric care. The next step might be to create a common organizational culture, which is permeated with continuous improvements, focusing on value-adding activities for the residents and others stakeholders. Originality/value: Very few studies have addressed lean implementation in geriatric care as well as in a municipal department.
