Introduction In today’s competitive world, it became very difficult for any industry/organization to sustain and grow substantially in market because of various challenges faced by organizations. Rapid changes in demand of customers and market can be specified as one of the reasons. Growth of any industry is mainly influenced by the extent to which they are utilizing their resources. Any step or change which improves utilization of resources will directly affect the productivity as well as profitability of the organization 1 . In tractor part industry, components are machined on various machines/stages before they are converted into a finished product. The machining processes are carried out in a specific defined order. Therefore, low productivity at any stage of production results in bottleneck formation affecting the productivity of whole plant. There can be many reasons which affect production rate as well as productivity of the machine or plant. It becomes necessary to obviate such obstacles so as to increase productivity and profitability of the organization. Therefore, in this research work, reasons responsible for delays in production shop were identified, further they were broken into elements and can be readily measured as fixed or variable. Finally, these measurements can be combined into work standards. Work sampling is a work measurement technique in which large numbers of instantaneous observations are taken at random intervals over a specified period of time of group of workers, machines or processes. Work sampling technique is used in measuring or forecasting, the rate of output of an existing or newly designed operation, also in determining how much time is consumed for various productive and nonproductive activities of a process or operation 2 . Abstract Objective: The aim of this paper is to study the operator activities in tractor part industry and the percentage distribution of various operations. The study also aims to analyze the personal and delay allowances by observing the operations and deriving the ratios within manufacturing period, so that utilization of machines can be enhanced by removing delays. Methodology: A work sampling technique was used in the current study; relevant reports are studied to give the basis and methodology of the technique. In accordance with work sampling technique the machines to be observed, the number of observations and the procedure for making observations are determined and the percentage distributions of unproductive activities are calculated. Findings: It is found that 74.43 percent of the available time for production of tractor components is utilized in productive activities and 25.57 percent of total available time is wasted due to avoidable and unavoidable delays. It is also observed that Setup time/ Job changing activity has maximum percentage of occurrence among all the delays i.e. 6.06 percent of the total available time.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
