Criteria for A Lean Organisation: Development of A Lean Assessment Tool
(2014) Pakdil, Fatma; Leonard, Karen Moustafa
Lean principles have long been recognised as a competitive advantage. Although there are several measures for various aspects of lean production in the literature, there is no comprehensive measure for overall lean implementation in business firms. An appropriate measurement tool is needed to assess the effectiveness and efficiency of the lean implementation throughout the entire organisation. Based on lean research, a comprehensive tool called the leanness assessment tool (LAT) is developed, using both quantitative (directly measurable and objective) and qualitative (perceptions of individuals) approaches to assess lean implementation. The LAT measures leanness using eight quantitative performance dimensions: time effectiveness, quality, process, cost, human resources, delivery, customer and inventory. The LAT also uses five qualitative performance dimensions: quality, process, customer, human resources and delivery, with 51 evaluation items. The fuzzy method allows managers to identify improvement needs in lean implementation, and the use of radar charts allows an immediate, comprehensive view of strong areas and those needing improvement. Practical uses of the LAT are discussed in the conclusion, along with possible limitations.
The Effect of Organizational Culture on Implementing and Sustaining Lean Processes
(2015) Pakdil, Fatma; Leonard, Karen Moustafa; 0000-0002-6299-6427; H-8189-2013
Purpose - Lean systems thinking was widely studied using relevant variables, but there is a dearth of published theoretical or empirical evidence about the cultural aspects of lean processes. The lack of conceptual development is one of the motivations for this study. Do organizational cultural variations correlate with the success and effectiveness of lean processes? What organizational infrastructures are required for effective lean implementation and continuation? The paper aims to discuss these issues. Design/methodology/approach - Examining literature in the area of lean production and lean management, the authors sought current literature at the intersection of organizational culture and lean processes, particularly implementation and sustainability, but found little relating to the topic. Therefore, using the Competing Values Framework taxonomy, the authors examine this intersection, relying on related research in the areas. Findings - In this paper, a brief discussion of lean processes in relation to organizational culture leads to propositions that identify the various cultural dimensions and their purported effect on lean implementation and sustainability. A model of this interaction is developed. Those quadrants of the Competing Values Framework that might be useful in developing research directions for the future are identified. Research limitations/implications - Future research directions include the measurement of organizational culture in firms that have implemented lean processes. This would be a step toward looking at the effect that the different quadrants in the Competing Values Framework have on various elements of lean efforts. This would take a significant amount of work, because the manufacturing industry, the leader in implementing and sustaining lean processes, may have institutionalized particular organizational cultures. It would be an interesting step forward in the understanding of how lean processes are operationalized across different firms and industries. However, there are multiple ways to examine culture; the authors believe this method allows the capture of the entire spectrum. Practical implications - Knowing which dimensions influence lean effectiveness and the way that they wield that influence allows managers to develop the firm's organizational culture to one that will support implementing and sustaining lean efforts. The challenge to implement and sustain lean processes lies in the need to identify the organizational culture infrastructure that will allow this system that was first used by Japanese firms to operate well in other organizational contexts. The values and norms that underlie lean processes may create conflict with the culture that already exists within the organization; such divergence retards adoption and performance. Originality/value - There is a lack of research at the critical intersection of organizational culture and lean implementation/sustainability. Culture is key to making the changes required of lean implementation and in sustaining the drive toward lean production and management. The paper begins to fill that gap.
Implementing and Sustaining Lean Processes: The Dilemma of Societal Culture Effects
(2017) Pakdil, Fatma; Leonard, Karen Moustafa
Lean processes allow the elimination of waste and the resulting improvements in productivity. However, implementing and sustaining lean processes are easier in some organisations than in others. There may be societal culture differences, as the successes in initial implementation in Japan have not been followed by global success. As organisations accelerate their lean efforts to gain or maintain competitive advantage, studying societal cultural effects seems timely. Understanding of the societal culture that the firm or subsidiary is operating in would be useful in determining how lean processes should lead the effort. Using the cultural dimensions developed by Hofstede, we examine the interconnection of societal culture and lean processes. For example, a societal emphasis on individualism is positively associated with a high level of lean process adoption, in terms of individual employee involvement, individual creativity and firm efficiency. A societal emphasis on high uncertainty avoidance is positively associated with a high level of lean process adoption, in terms of control and standardisation, efficiency and long-term philosophy. A societal emphasis on high power distance is positively associated with a high level of lean process adoption, in terms of control and standardisation, and efficiency. A long-term orientation in the society will be positively associated with a high level of lean process adoption, in terms of all of the dimensions. A societal emphasis on femininity will be positively associated with a high level of lean process adoption, in terms of employee involvement, creativity and long-term philosophy.

Validation of Qualitative Aspects Oof The Lean Assessment Tool (LAT)
(2018) Pakdil, Fatma; Toktas, Pelin; Leonard, Karen Moustafa
Purpose - The purpose of this paper is to test the reliability and validity of the qualitative section of Lean Assessment Tool (LAT) starting from the point where a reliable and valid tool is needed to measure increasing leanness level of business organizations. Design/methodology/approach - The questionnaire used in this study included the qualitative component of LAT developed by Pakdil and Leonard (2014). The unit of the study was individual employees who work in manufacturing firms participating in this study. This study focused on the data collected from three firms that operate in Turkey and two firms that operate in the USA. The total respondents from Turkish firms were 263 employees, while the 205 employees responded from US firms. Findings - Exploratory factor analysis and confirmatory factor analysis were completed to determine valid and reliable factors that compose LAT's qualitative component. The statistical analysis showed five distinct factors, namely process, delivery, quality, customer satisfaction and human resource. In addition, the fuzzy logic showed appropriate loadings to make the argument for its use in analysis of the LAT. Research limitations/implications - This study moves the debate about the success or failure of lean efforts forward. With the debates about lean and its potential, it is necessary to have a scientific determination of success and the areas where further work in the firm is needed. Such measurement is the backbone of management progress, and the authors believe that this paper is useful. Second, the necessity of reliable and valid tools of lean assessment is obvious in the literature and practice. The findings of this study help academicians find reliable and valid tools to measure lean success both in the literature and practice. Practical implications - Managerial implications include the development of a way to assess the areas of success and areas requiring further work. Failure to measure success and needs for further work has been the reason for the questionable results found in investigating lean implementation efforts. If there is no way to determine what is needed to improve lean efforts, they will be seen as failure, even if part of the implementation has been successful. This tool has been found to be potentially useful for evaluation of these crucial and time-consuming efforts. Originality/value - In this study, the qualitative section of LAT has been validated. The results demonstrated that, based on two countries' data sets, the scale was found to be reliable and valid within itself and across sociocultural boundaries.
