Abstract Lean manufacturing is more than just a set of tools and techniques; it also requires a change in the organizational culture of the company involved to be a lean culture. The relationship between an organization‟s culture and its ability to implement lean six sigma technique is a longterm effort. Many manufacturing companies, when implementing lean manufacturing, emphasize only on lean tools and techniques. They ignore the human factor, or more specifically, they fail to build the right culture. Hence, these companies could not obtain the full benefits of lean manufacturing implementation, and in fact, they have difficulties sustaining the success attained. It is becoming increasingly important for companies to be responsive to global demands in order to remain competitive. Many companies are looking at lean manufacturing to help them for achieving this objective. The creation of an organization that has a culture of continuous improvement and achieving results through its various principles and philosophies is a main factor in Toyota Way Model. This research investigates the critical lean culture criteria model for successful implementation of Lean Six-Sigma methodologies. This model is built on the literature review that involves major sources of lean manufacturing community, and also is based on Toyota way culture. II The model helps organizations to assess their internal culture and adopt the lean culture criteria in order to recognize the full benefit from implementing lean methodology. The aim of this research is to analyze and determine the factors related to the impact of an organization‟s culture on the concepts of lean manufacturing based on the Toyota Way model. This aim is achieved by analyzing how conducive the current organizational culture at manufacturing companies to the implementation of lean six-sigma principles. The research uses a critical lean culture criteria model that has been designed by the researcher and was aligned to the principles relevant to the Toyota Way model. The researcher constructed a group of questions for every lean culture criterion, such that, when the organization answers these questions, it can assess the level of presence of this criterion in the organization. All questions are collected in a developed questionnaire to assess the current lean culture in radiator manufacturing and car assembling companies. The conclusion from this research indicates that the developed critical lean culture criteria model is valid to assess the organizational culture of the manufacturing companies, and successfully defined the areas of strengths and weaknesses in these companies for successful implementation of Lean Six-Sigma methodologies |
