Frequent machine breakdown, high changeovertime, and high manufacturing cost are becoming great threat. The author’s main aim to keep up the Research is to improve OEE to meet customer’s increasing demands without addition of capacity thus meeting business goals. This document demonstrates the need to overcome most of bottleneck of equipment’s unavailability for resources utilization and to run the process more effectively. Improvement in OEE was possible through reducing the changeovers and cycle time and developing the workforce culture align to the focused improvements. The outcome of this Research may expect to have marked improvement in productivity with best utilization of the capacity along with right quality product, at right time.  \nKeywords—Equipment downtime, Productivity, Losses, Cycle time.  \nI. INTRODUCTION  \nIn all the manufacturing industries delivering the quality product at the right time has become more challenging intoday’s market situation . The paper Use of Spaghetti diagram for identification and elimination of waste movements in shop floor for OEE Improvement Maintenance has become more challenging in the current dynamic business environment. The manufacturing sector has been experiencing tremendous challenges in ensuring all products are delivered to customers on time. However, the current business environment and pressures from various parties such as customers, suppliers, governments and so forth have put manufacturing sectors under severe pressure. To operate efficiently and effectively, manufacturing sectors need to ensure no disruption due to equipment breakdown, stoppages and failure.  \nManufacturing systems in particular often operate at less than full capacity, with low productivity, and the cost of producing products are high. Recent study (Mobley,1990) shows that 25-30% of total production cost is attributed to maintenance activities in the factory. The quality of  \nmaintenance significantly affects business profitability. The importance of maintenance functions has increased due to its role in keeping and improving the availability, product quantity, safety requirements, as maintenance costs constitute an important part of the operating budget of manufacturing firms (Al-Najjar and Alsyouf 2003:85-100) . In response to maintenance problems encountered in manufacturing environment, the Japanese developed and introduced the concept of Total Productive Maintenance (TPM), in 1971. TPM is a maintenance system defined by Nakajima (Nakajima 1988) in Japan, which covers the entire life of equipment in every division including planning, manufacturing, and maintenance. It describes a synergistic relationship among all organizational functions, but particularly between production and maintenance, for continuous improvement of product quality, operational efficiency, capacity assurance and safety.  \nII. LITERATURE SURVEY  \nA. SPAGHETTI DIAGRAM:  \nA spaghetti diagram is a visual representation using a continuous flow line tracing the path of an activity through a process. The continuous flow line enables process team to identify redundancies in the work flow and opportunities to expedite process flow.  \nThe intent of this in literature review was to identify ways to shorten the walking time from one activity to another for frequently performed tasks","cbCaikV6jvLEuVxI","https://ap.wps.com/l/cbCaikV6jvLEuVxI","pdf",807822,"English","# I.
