Study Techniques

Lean manufacturing and work study are both popular and have been widely applied to achieve quality and productivity improvement in several industrial sectors (automotive, health care, and etc.) with high success. 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 performance. The case study results indicate the relationships, differences, and similarities between the techniques and the benefits of each. In fact, lean manufacturing techniques provide a good overview of processes, whereas the work study techniques focused on critical areas. The effects of applying these techniques are contrasted. Finally, time spent and cost were reduced at the outbound logistics stations.

Abstract: Lean manufacturing has been one of the most standard method in the manufacturing and service industry for elimination of waste. Every manufacturing industry has to put in continuous effort for its survival in the current impulsive and competitive economy. The purpose of this paper is to investigate the adoption of lean manufacturing tools and techniques in the manufacturing industries. This paper is based on actual implementation of lean manufacturing techniques. It focuses on the execution of flow from the start until the end of the implementation, types of analysis and tools applied, evaluation methods and how the industry benefited from the implementation. In this case study we particularly focused on Shop floor management, Quality Management (QM), Supplier and Customer Management (SCM) and Workforce Management (WM). After going through various testing on implementation of Lean Manufacturing principles in Micro Small medium Enterprise (MSME), researcher studied thoughts of some author where they discussed pragmatic problems they overcome while implementing lean principles in developing economies MSME. At the end, the result shows that there is monthly increment in capital productivity and labour productivity. And decrement in inhouse rejection, breakdown hours and customer complaint from the implementation of lean.

Global Performance

PurposeThe purpose of this paper is to present the “Assessment Model of Lean Effect” (AMLE), a theoretical model that measures Lean manufacturing implementation effect over the global performance of a company.Design/methodology/approachAMLE model is divided in two criteria types: the “Facilitators criteria” and the “Results criteria”. “Results criteria” are inspired from the European Foundation for Quality Management (EFQM), Global Reporting Initiative (GRI) and ISO 26000. The “Facilitators criteria” are based on the main philosophy of the Lean manufacturing, which is the total elimination of all types of waste. The development of the scoring scale was based on the results, approach, deployment, assessment and review (RADAR) philosophy and the experience of nine consultants from the automotive field; the choice of the consultants was based on three conditions. Furthermore, each consultant has his\her own weight according to its expertise. Lastly, the AMLE was validated via a case study set in an automotive industry company called FEBA. The validation process is divided in two different steps: the first step is related to Facilitators assessment and scoring; via the evaluation of the different projects implemented by FEBA to eliminate the different types of waste. The second step concerns Results assessment and scoring, via the evaluation of the performance measurements used by FEBA to assess the effect of the Facilitators' implementation.FindingsThe developed model (AMLE) enabled the Lean manufacturing effect assessment on the global performance of a firm from the automotive field. The case study results reveal that the aforementioned firm does not give priority to social measurements. Consequently, the performance of the firm was negatively impacted.Research limitations/implicationsThe criteria of AMLE are inspired from the definition of the Lean manufacturing given by Taiichi Ohno, from ISO 26000 and from GRI; meaning that these criteria could be adjusted if other references existed or developed. In addition, the scoring rules are established according to the experience of a limited number of consultants from the automotive field. The scoring rules establishment would lead to meaningful outcomes, if the number of participants was increased. During the assessment of the global performance, the perception of the auditor plays an important role in terms of scoring because the scoring rules allow the possibility to the auditor to give from the minimum to the maximum of the score, according to his perception and experience. For the case study, the validation of the developed model requires starting with the “Facilitators” implementation process and then measure the generated global performance. However, due to time constraints and limited opportunities for new projects, the validation was based only on existing projects managed by the firm. To address the study limitations, it is envisaged to detail and explain the scoring rules while extending the number of consultants. Furthermore, the assessment of Lean manufacturing global performance through the AMLE model may be subjective and requires a mathematical modeling. In fact, the Lean manufacturing performance assessment via the developed model could have a degree of subjectivity; that is why the design of a mathematical model seems required.Practical implicationsThe research findings may direct practitioners and decision makers to the importance of assessing the global effect of the Lean manufacturing on the overall performance of the firm. The AMLE model is a tool allowing the assessment of Lean manufacturing effect over economic, environmental and social performances.Originality/valueThe developed model is the first one assessing the global performance generated by the elimination of waste via the application of the Lean manufacturing.

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%.

The purpose of this study is to make productivity better by means of 5S, work study, and Muda elimination in corrugated carton industry which was conducted from November 2018 to March 2019 from a case study of XYZ Co., Ltd. The data were collected from managers and supervisors and the problems were analyzed by brainstorming together with cause and effect diagram. Crucial problems of production occurred from human errors, i.e. production employees ignored to check the availability of machines before operating the machine, production employees neglected to prepare materials for next orders while machines operating, and warehouse employees randomly checked the humidity before the storage of corrugated sheet papers. Employees could be trained about production process, machine operation, quality inspection, and planning process. The production process could be changed from operating machine without checking machine availability and removing material remains in the machine to check availability and removing materials remains in the machine before operating new purchasing order. The output was then increased from 2,000 to 2,300 ton per month, accounting for 15.00 percent of improvement. The defect was reduced from 160 to 140 pieces per month, accounting for 12.50 percent of improvement. Regarding the storage process, it could be changed from random check of humidity to check of humidity every time. The messy in warehouse had caused mixing of wet or damp raw materials with good quality raw materials. Once it was improved by cleaning, classifying materials, products and areas with sign boards, the results showed that the materials and products were easier to find and product quality was increased. Company launches 5S policy and doing 5S activities continuously twice a month. The findings presented that the number of employees who neglected to comply with the organizational regulations was reduced from 6 to 2 persons, accounting for 66.67 percent of improvement.
