Six Sigma is a widely used Operational Approach towards Operations Management and is frequently applied within Manufacturing Businesses, however the fundamental processes also apply within businesses operating within the Service Industry. The Purpose of Six Sigma is to reduce process variation so that virtually all the products or services provided meet or exceed customer expectations. Six Sigma adopts a very data driven, disciplined method for eliminating defects within processes and promoting business improvement within organisations. Six Sigma is able to show quantitatively how a process is performing and to achieve ‘Six Sigma Status’, a process must not produce more than 3.4 defects per million opportunities. Six Sigma is dissected into three core elements including: Process Improvement, Process Design/Re-Design & Process Management and will be explored below. 1. Process Improvement The Process Improvement aspect of the Six Sigma Model addresses the concept of improving existing processes with the ultimate objective of 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
Meaning of Value Analysis
The purchasing manager conducts value analysis that aims mainly at achieving cost effectiveness and maintaining the required level of quality. Value analysis is an organized effort that studies in detail the ‘value’ of material. Value Analysis reviews the design changes with the objective of eliminating high cost materials and the materials that are technically obsolete and reducing the number of parts. After analyzing the functions and cost of material, the purchasing manager evaluates the possibilities of using the material. Value Analysis can be defined as a process of systematic review that is applied to existing product designs in order to compare the function of the product required by a customer to meet their requirements at the lowest cost consistent with the specified performance and reliability needed. The Value Analysis technique was developed after the Second World War in America at General Electric during the late 1940s. Because of World War, 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
Project Production
Project production is characterized by complex sets of activities that must be performed in a particular order within the given period and within the estimated expenditure. Where output of a project is a product, such products are generally characterized by immobility during transformation. Operations of such products are carried out in “fixed position assembly type of layout” which can be observed in production of ships, locomotive and aircraft, construction of roads, buildings, etc. Characteristics of Project Production Definite beginning and definite end: Each project has a definite beginning and a definite end. “Fixed position” layout: Where the output of a project is a product, such products are generally characterized by immobility during transformation. Operations on such products are carried out in “fixed position assembly type of layout” which can be observed in production of ships, locomotive, aircraft, construction of roads/ buildings, etc. High cost overruns: Often delays take place in Continue reading
Objectives of Material Handling
Materials handling may be defined as the art and science of movement, handling and storage of materials during different stages of manufacturing considered as material flow into, through and away from the plant. It is in fact, the technique of getting the right goods safely, to the right place, at the right time and at the right cost. All tangible and intangible benefits can be reduced to four major objectives. The application of material handling methods and equipment to be of greatest benefits should be governed by the following: 1) Reduced Costs: Cost-Reduction programs have two broad goals; either to reduce the cost of Material Handling or to reduce total production cost; by improved handling procedures. The latter concept net reduction in total manufacturing costs. The Ways in which cost reductions are realized through improved material handling are; Reducing material handling labour. Reducing the Material handling work done by direct Continue reading
