Conclusion
Based on the research, we can say that the experience of the Lean method by health-care managers was mainly positive. In addition, the organizations studied were progressing in the application of the Lean method, which indicates that the Lean method is seen as suitable for daily work in health care and its development. The middle managers experience highlighted improved communication, greater operational efficiency, new tools for use in the workplace, as well as an increase in the discussion culture. On the basis of the experience of the managers, we can say that the Lean method is suitable for health care.
Features which have earlier received international criticism regarding the Lean method were also raised by the respondents in our survey. It is not possible to unequivocally measure and show that most of the positive experiences achieved by the method were actually due specifically to the activities in accordance with the method and the application of its various tools. However, the local managers felt that individual results can be achieved solely through the application of Lean tools. The research brings forth understanding and knowledge of managers experiences of the Lean method in Finnish health care. It emerged from this research study that a common set of values which respects human dignity developed due to the use of the method and was discernible as a common set of patient and workplace community values. The main objective of Lean methods is for an organization to develop a process-oriented management strategy without producing waste. Based on the results of this research, it is clear that managers experienced a lack of time for the implementation of Lean methods and physical structures limited the development of day-to-day functions as well. If the organization is not committed to the method, according to the interviews it will have little chance of success, given that the development policies require the allocation of resources for additional training, as well as the development of the relevant processes. This was reflected in interviews with concerns about how working time would be sufficient for all the development required.
