| IMPLIMENTING LEAN TOOL JET IN GEAR | | | | RESEARCH METHODOLOGY: |
| MANUFACTURING COMPANY | | | | Initially the general information of the company is |
| A STUDY | | | | accessed from the website of the company. |
| Prabhat Kumar, Ajay Verma | | | | Subsequently the detailed information is available from |
| | | | | the plant visit. The information obtained during |
| | | | | discussion with, managers, production in charge, |
| Shri G.S.Institute of technology and science Indore | | | | supervisors, workers, etc. Information is collected |
| (M.P.) | | | | regarding the identifying area, which include system of |
| | | | | 5s, kaizen, JIT, Quality management. The information |
| - A STUDY | | | | was made available through company records, |
| | | | | documents etc. |

| manufacturing company. The concept of the Toyota | | | | Case Study addresses the application of lean |
| Production System or what is known today in the US | | | | manufacturing concept to the continuous production |
| as “Lean Manufacturing.” The basic idea behind | | | | process sector with a focus on the process industry. In |

| the customer’s perspective. The primary objective | | | | 1. Overproduction – In Industry the reasons of the |
| of lean manufacturing is to assist manufacturers who | | | | overproduction is poor flow of information, and |
| have a desire to improve their company’s | | | | management also want to engage the worker for |
| operations and become more competitive through the | | | | production, and also Lack of stable schedules. |

| U.S. manufacturers have always searched for | | | | |
| efficiency strategies that help reduce costs, improve | | | | |
| output, establish competitive position, and increase | | | | |
| market share. Early process oriented mass production | | | | |
| manufacturing methods common before World War II | | | | |
| shifted afterwards to the results-oriented, | | | | |
| output-focused, production systems that control most | | | | |
| of today's manufacturing businesses. After World War | | | | |
| II Japanese, manufactures were faced with the | | | | |
| dilemma of vast shortages of material, financial, and | | | | |
| human resources. The problems that Japanese | | | | |
| manufacturers were faced with differed from those | | | | |
| of their Western counterparts. These conditions | | | | |
| resulted in the birth of the “lean” manufacturing | | | | |
| concept. Lean Manufacturing initiative focused on cost | | | | References |
