In the era of cut throat competitive market, Indian industries are under tremendous pressure to continuously reduce the cost and improve product quality. The main objective of this research paper is to provide a road map for investigating the opportunities to reduce cost and improve productivity and quality in the existing production system through the application of Lean-Kaizen concept using value stream mapping (VSM) tool at shop floor of an Indian Small-Scale Enterprise (SSE). On the basis of collected data from the selected industry, a current state map was made. After analysis, the current state map was modified to develop a future state map. By comparing current and future state map, the gap areas were identified and takt time (TT) was calculated considering actual market demand. To overcome the gap between current state map and future state map and to synchronize cycle time of each station with talk time, Kaizen event (KE) was proposed. Fuzzy technology for order preference by similarity to ideal solution (TOPSIS) was applied to prioritize and select the appropriate KE for optimized performance level. After analysis of data obtained after application of the Lean-Kaizen concept, the final improvements in terms of improved productivity (57.15%) and reduced lead time (69.47%), reduced cost (65.61%), and station cycle time (75.25%) were recorded. Through the case study drawn from realistic situations of the industry, the authors highlight that implementation of Lean-Kaizen using VSM and fuzzy TOPSIS provides improvement opportunities across the organization. The findings can inspire the SSEs to adopt the Lean-Kaizen concept for optimizing continuous improvement opportunities in their production industry. This study offers the researchers and practitioners a good example for understanding, selecting, and performing KE program. They can even attain more improvement in various areas by establishing or improving these KE programs.

PT. IE is engaged in the business of making Lighting and Lampposts. Based on observations and interviews, there are still some wastes that arise in the flow of the production process, among which there are still many wastes of waiting time, transportation, movement and inventory. These wastes cause the product completion time to be longer and the resulting quality decreases. To eliminate or reduce waste, it is necessary to apply Lean Manufacturing. Lean Manufacturing is a systematic approach to eliminating waste and changing processes by identifying and reducing waste with continuous improvement and striving to create a production flow along the value stream by eliminating all forms of waste and increasing the added value of products to customers. From the Pareto diagram, it is found that transportation waste has the highest percentage of 26.21%, waiting time is 21.38%, motion waste is 19.31% and waste inventories are 15.17%. while the results of the Value Stream Mapping Current State Map mapping obtained a production lead time of 7,680 seconds and a total cycle time of 6,660 seconds and a PCE Current State Map value of 53.09%. Identify the root causes of waste using Fishbone diagrams, 5 Why Analysis, 5W+1H, Fault Tree Analysis and FMEA. After corrective actions have been taken, based on the Value Stream Mapping Future mapping there is a decrease in production lead time to 5,220 seconds and a decrease in total cycle time to 4,860 seconds and an increase in PCE Future State Map to 68.10% so that there is an increase of 15.01% which shows The company's production process has become more Lean.PT. IE bergerak dalam bisnis pembuatan Lighting dan Tiang Lampu. Berdasarkan observasi dan wawancara, masih terdapat beberapa pemborosan (waste) yang timbul di aliran proses produksi di antaranya masih banyak terjadi pemborosan-pemborosan waktu tunggu, transportasi, gerakan dan inventori. Pemborosan-pemborosan tersebut menyebabkan waktu penyelesaian produk menjadi lebih lama dan kualitas yang dihasilkan menurun. Untuk menghilangkan atau mengurangi pemborosan diperlukan adanya penerapan Lean Manufacturing.Lean Manufacturing merupakan pendekatan sistematik untuk mengeliminasi pemborosan dan mengubah proses dengan cara mengidentifikasi dan mengurangi pemborosan dengan perbaikan kontinu dan berupaya untuk menciptakan aliran produksi sepanjang value stream dengan menghilangkan segala bentuk pemborosan serta meningkatkan nilai tambah produk kepada pelanggan. Dari diagram Pareto ditemukan waste transportasi memiliki persentase paling tinggi sebesar 26,21%, waktu tunggu  21,38%, waste motion 19,31% dan waste inventories 15,17%. sedangkan hasil pemetaan Value Stream Mapping Current State Map diperoleh production lead time selama 7.680 detik dan total cycle time selama 6.660 detik serta nilai PCE Current State Map sebesar 53,09%. Identifikasi akar permasalahan pemborosan menggunakan diagram Fishbone, 5 Why Analysis, 5W+1H, Fault Tree Analysis dan FMEA. Setelah dilakukan tindakan–tindakan perbaikan, berdasarkan pemetaan Value Stream Mapping Future ada penurunan production lead time menjadi 5.220 detik dan penurunan total cycle time menjadi 4.860 detik serta ada peningkatan PCE Future State Map menjadi 68,10% sehingga ada peningkatan 15,01% yang menunjukan proses produksi perusahaan telah menjadi lebih Lean.

The Construction and Demolition (C&D) industry is very close to various waste management issues as the generation of waste is inevitable in every construction. In Indonesia, to make an applicable implementation of C&D Waste Management, the improvement must be made by looking into the actual field process. The improvement uses DMAIC as the lean tools and VSM to state the current process of material from its delivery on the site into a waste. Waste that is being monitored is the most used materials in the case study project which are concrete. A notable project was taken for the study as it will help other structure projects to imitate the down-to-earth future state, aiming at the reduction of waste generation rate and also business process improvement. The result shows that the process of concrete from orders to waste took eight steps, and three of them are improved, producing 3% lesser waste from the current state. The best scenario WGR were analyzed to also answer the stakeholder interest within the case study.

High-end cabinet making is traditionally an artisan process that utilizes few manufacturing principles. Manufacturing lead time, labor hours required, and productivity can be improved by industrializing the process. This paper focuses on a case study of a high-end cabinet manufacturer in Edmonton AB, Canada and the proposed process and facility improvements. First, computer simulation using Simphony.NET and movement analysis of people/materials of the cabinet manufacturer’s current state of operations is conducted to establish a baseline. Next, suggested process and facility layout improvements and their anticipated results are quantified through future state simulation in order to aid management in making decisions for plant changes and to prove their effectiveness. These improvements include: application of lean principles, modification of their current production methods to reduce bottlenecks, and future state facility layout based on an optimized flow of people and materials.
