PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations

Abstract Background: The peripherally inserted central catheter implantation and maintenance process was optimized at Shanghai Fu Dan University Cancer Center using lean-based methodology. Problems addressed were coping with capacity limitations and streamlining the process of patient care to reduce potential complications associated with delays in catheter administration. These clinical processes were evaluated with regard to pretreatment areas—such as booking, waiting, and patient education—and solutions were recommended to the problems that were identified. Methods: Lean methodology was used under actual clinical settings to improve the clinical process, using observations, patient surveys, interviews, data analysis, and a kaizen workshop. Three tools were applied from lean methodology: value stream mapping, bottleneck calculation, and fishbone root cause analysis. The philosophy of kaizen was used to enhance teamwork, boost morale, and encourage all members of the frontline nursing team and administration leaders to contribute ideas and suggestions for improvement. Results: A value stream map and a redesigned future value stream map were plotted at the workshop to identify problems related to inefficiency and waste and to aid in proposing solutions. Implementation of these solutions resulted in smooth and steady patient distributions on days with the largest patient volume during a typical week and an increase of 30% in the number of patients that could be seen in a week. Conclusions: The economic methodology of lean manufacturing, especially value stream mapping, can be a powerful tool for visualizing and better understanding processes to reduce waste and reengineer a standardized workstream in settings where peripheral intravenous central catheters are placed.

Productivity is an important parameter for all small and medium scale manufacturing industries. Lean manufacturing emerged as production strategy capable of increasing productivity by identifying and eliminating non value added activities. This article deals with productivity improvement in a pre-assembly line of gearbox manufacturing company with a case study using lean concepts like process flow chart, process Gantt chart and time study. This paper illustrates using a case study on how a value stream mapping has to be carried out in a planet carrier pre-assembly line. Value stream mapping and work standardization are the key tools used in lean manufacturing and lean transformation. It makes the process smoother, helps in reduction of lead time and ultimately increasing the productivity. From the observed results it was found that, the productivity has been increased from 7 pieces to 10 pieces in the first step assembly when the proposed VSM was implemented. The second step processing time was reduced by the execution of proposed value stream mapping with TAKT time of 126 minutes and 165 minutes of processing time for demand of 10 pieces were achieved and the overall processing time has been reduced by about 24%.
