The application of lean methods has been used to eliminate non-value added activities from business and manufacturing operations. By eliminating non-value added activities, organizations havebeen able to reduce costs, improve process flows, and increase value for customers. The popularity and benefits of lean methodshave led to a demand for an engineering curriculum that includes lean principles and methods. Engineering student learners oftendo not have experience in manufacturing operations at the point in which they are introduced to lean principles and methods intheir studies, thus selecting appropriate teaching methods is important in ensuring that students develop a working knowledge ofhow to apply lean tools. Previous research has demonstrated the importance of learner perceptions ...

Previous studies found that some researchers apply lean manufacturing techniques only, whereas others apply only work study. But not all, some studies have used both techniques for productivity improvement. Therefore, a number of questions remain concerning the gap between the applications of these two techniques. The aim of this research is to fill the gap between these two techniques by reviewing the relationships, differences, and similarities between these two techniques; the results of the two techniques' applications to real case, studies and outbound logistics activities will also be reviewed. A literature review has been conducted to gain an overview of both techniques. Moreover, the case study have shown that both techniques demonstrate enhanced productivity pe...

The purpose of this research project is to improve the quality of healthcare and patient satisfaction utilizing Lean principles. This research is conducted in a middle-sized Pluakdaeng hospital in Rayong, Thailand where there are approximately 364 patients daily under the supervision of 6 doctors, 6 pharmacists, 53 nurses and 124 supportive staffs. In Lean studies, computer simulation and Value Stream Mapping (VSM) are utilized to define and eliminate wastes in the hospital business process. Findings indicate that service rate at the hospital can be increased to 28.98% and the average patient waiting time can be reduced to 28.65%. Future work, improvements, limitations and suggestions on the current research are also provided and discussed.

Corporate brand management has increasingly been seen as a strategic key issue from the point of view of shareholders / owners, top management and other stakeholders. This is due to the fact that in the ever increasingly turbulent, dynamic and competitive markets, corporate brands are ways of creating trust, stability, and differentiation in the market. Organizational learning prioritizes the creation and acquisition of new knowledge, and emphasizes the role of people in the creation and utilization of that knowledge. In this way, organizational learning presents an important route to performance, success and competitive advantage for the organizations. The strategic marketing literature reflects a growing interest in the role of competitive environment on a firm’s marketing strategy and performance. Drawing on organizational learning theory and strategic choice theory, it is argued that a firm’s strategic adaptation occurs through managerial perceptions of its corporate identity, which then contributes towards its corporate branding. The focus of this research paper is on exploring the impact of organizational learning on corporate branding of the firm. While the importance of these issues has been widely accepted, to date the linkages between organizational culture, learning, corporate branding and corporate identity have scarcely been examined together in the literature, particularly from an empirical perspective. There is some evidence that organizational learning is associated with employee commitment to enhance the corporate brands, but only a few studies have focused on the effect of culture and learning on corporate identity and corporate branding. This research paper explores the relationship between the two broad concepts, with empirical research on data collected from 5 retail organizations within the UK market.

To date, lean manufacturing principle is one of the successful improvement concepts that have been applied to eliminate waste and non-value added activities that occur in many companies. This paper explores a real work case study of the manufacturing sheet metal stamping process to demonstrate how lean manufacturing can help improve work efficiency. This study was conducted within 10 months, started from July 2013 till April 2014. Lean and other improvement tools and techniques such as visual control, Poka-Yoke, and 5s were applied to help companies identify areas of opportunity for waste reduction and improve the efficiency of production processes. Studies of the company processes showed that the deburring and polishing processes tend to create the most non-value added activities and should be addressed as quickly as possible. The improvement results have shown a positive impact on the company productivity improvements. The significant results indicate that the processing time of a polishing stage, after applying lean manufacturing principle, was reduced from 6,582 seconds to 2,468 seconds or by 62.5%. Also non-value added activities were reduced from 1,086 activities to 261 activities, or by 66.53%. Furthermore, overtime cost was reduced by 1,764 Dollar per year.

However, few studies have investigated the relationship of these types of teaching innovations with other learner characteristics, such as self-efficacy and background knowledge. This study explored the effects of collaborative activities and simulation sessions on learning and the relationships between selfefficacy beliefs, background knowledge, and learning. Data were collected from two different terms in an upper division engineering course entitled Lean Manufacturing Systems Engineering. Findings indicated that the impact of collaborative activities and simulation sessions appears to be different, depending on the concepts being taught. Simulation sessions were found to have a significant effect on self-efficacy beliefs, and background knowledge had a mixed effect on learning. Overall the results of this study highlight the complex set of relationships between classroom innovations, learner characteristics, and learning.
