Work Study forms the basis for work system design. The purpose of work design is to identify the most effective means of achieving necessary functions. Work study aims at improving the existing and proposed ways of doing work and establishing standard times for work performance. Work design involves job design, work measurement and the establishment of time standards and worker compensation. Work Study is encompassed by two techniques -method study and work measurement (time study): Method study is the systematic recording and critical examination of existing and proposed ways of doing work, as a means of developing and applying easier and methods and reducing costs. The main purpose of method study is to eliminate the unnecessary operations and to achieve the best method of performing the operation. Method study is also called methods engineering or work design. Method engineering is used to describe collection of analysis techniques which focus on improving Continue reading

Kaizen – Definition, Meaning, Process, Implementation, Advantages and Disadvantages
What is Kaizen? Japan’s management philosophy has introduced a new creative strategy for competitive success in business, or the so-called “Kaizen” model. The term Kaizen began to receive attention from management experts and scholars around the world when Masaaki Imai published his first book in 1986, “The Key to Japan’s Competitive Success”. Kaizen is a Japanese word with literally mean improvement, taken from words ‘Kai’, which means continuous and ‘zen’ which means improvement. Some translate ‘Kai’ to mean change and ‘zen’ to mean good, or for the better. In the context of Lean manufacturing, kaizen is understood to signify small, incremental, and frequent improvements to a process. Lean philosophy states that the large improvement which just require small amounts of investment and risk. The kaizen main mindset is making process improvements without adding people and space to the process. The more important one is implement the change without spending the Continue reading
Methods of Production – Job, Batch and Flow Methods
Production and operation management has become an essential part of manufacturing organizations. These organizations always experience pressure in all divisions and units. Pressures are in terms of orders to be completed on due dates, breakdown of machines, absence of employees, lateness on delivery of materials, and industrial actions by employees to improve working conditions. To meet these challengers, firms usually rely on an effective methods of production and operation methods. A manufacturing organization may use different methods of production such as use job, batch or flow production depending on a number of factors. However, it is important to have a clear distinction between these three methods of production to know where each one is applicable. Whatever methods of production is used, the objective is to produce goods and services which is highly profitable and to use the most effective and efficient method. Considerations should also be made to other aspects Continue reading
Steps in Production Planning and Control
Production planning and control is one of the most important phases of production management, it is, as a matter of fact, the nervous system of a manufacturing organization. In manufacturing organization, it is essential that production is carried on in the best manner at the lowest cost, and the goods are of right quality and are produced at the proper time. This can be ensured only through proper planning of production. but mere planning of production will not solve the problem because production plans are not capable of self-actuating and do not lead to automatic accomplishment. For that the production manager has to take certain steps like, he has to regulate work assignment, review the work progress, and devise methods to bring conformity between the actual performance and planned performance — so that plans chalked out are adhered to and the standards set at the planning stage are properly attained Continue reading
Lean Manufacturing – Definition, History, Objectives, and Examples
Lean manufacturing is the production of goods using less of everything compared to mass production. It focuses on less human effort, less manufacturing space, less investment in tools, and less engineering time to develop a new product. Lean manufacturing is a generic process management philosophy derived mostly from the Toyota Production System (TPS). Lean manufacturing is a technique that allows companies to be more responsive to quickly changing markets and more sophisticated & demanding customers. History of Lean Manufacturing Toyota is often considered one of the most efficient manufacturing companies in the world and the company that sets the standard for best practices in Lean Manufacturing. Lean Manufacturing has increasingly been applied by leading manufacturing companies throughout the world, lead by the major automobile manufactures and their equipment suppliers. Lean Manufacturing is becoming an increasingly important topic for manufacturing companies in developed countries as they try to find ways to Continue reading
5 Why Analysis – A Root Cause Analysis Tool
5 Why Analysis is a simple approach for exploring root causes and instilling a “Fix the root cause, not the symptom,” culture at all levels of a company. The 5 Why Analysis was originally developed by Toyota founder Sakichi Toyoda and was later used within Toyota Motor Corp. during the development of the Toyota Product System (TPS). At Toyota, 5 Whys is still a critical component of problem-solving training, and the method is still widely applied within the company when problems occur. “Toyota Business Practices dictates using the ‘Five Whys’ to get to the root cause of a problem, not the ‘Five Whos’ to find a fire the guilty party.” – Jeff Liker, The Toyota Way It can be used whenever the real cause of a problem or situation is not clear. Using the 5 Whys is a simple way to try solving a stated problem without a large detailed Continue reading
