Quality Control (QC) is a system of routine technical activities, to measure and control the quality of the inventory as it is being developed. The Quality Control system is designed to: Provide routine and consistent checks to ensure data integrity, correctness, and completeness; Identify and address errors and omissions; Document and archive inventory material and record all QC activities. Seven Quality Control Tools An organization can be made better by applying proper quality management and quality management tools and techniques. The following seven quality control tools are considered basic tools for achieving quality. Tools Techniques Checksheet Departmental purpose analysis Pareto diagram Poka-yoke Histogram Fault tree analysis Control chart Design of experiments Scatter diagram Quality function deployment Statistical process control Flowchart Failure mode and effects analysis Cause and effect diagram Benchmarking The above basic tools are classified under 2 categories “Data Acquisitions” and “Data Analysis”.

Production Management Techniques
Inspection in Production Management – Concept, Objectives and Stages
Production control is introduced not merely to ensure that the goods will be produced on time, but is also meant to see that the goods produced are of the right quality. This is done through inspection of the products manufactured. Since the purpose of inspection is to compare the products with the standards of quality set earlier, it too, can be regarded as an effective agency of production control. One way of inspection is to examine the quality of finished products at the end of the process of production. But this may involve too much of wastage in the form of rejected products. To minimize the rejection of defective products, inspection may be conducted at every stage of production. Inspection can occur at three points: before production, during production, and after production. The logic of checking conformance before production is to make sure that inputs are acceptable. The logic of Continue reading
Kaizen and Kanban in Lean Manufacturing
Kaizen Kaizen is broadly interpreted as the Japanese term for continuous improvement, although it is perhaps more accurately translated as a form of control. It applies to all aspects of organisational output, and can thus be linked to both Toyota Production System (TPS) and types of waste, as well as the means of introducing and managing basic employee working conditions. One of the most popular tools of Kaizen is a Kanban, which of itself translates to differing types of organisational process control, which collectively lead to greater organisational production efficiency. The overarching principle of Kaizen, and Kanban within that, is to create a ‘pull through’ organisational process, as opposed to push through. Historically, for many manufacturing organisations, understandably, they would place the manufacturing process itself at the heart of operations, and would strive to make this element as efficient as possible working towards metrics such as overall equipment Continue reading
Quality Control (QC) – Meaning, Definition, and Benefits
What is Quality? Quality has become one of the most important factors of consumers decision in selecting a product among competing products (services). This phenomenon is wide spread regardless of the fact whether the consumer is an individual organisation, retail store, or a military defense programme. The quality of products / services can be evaluated in several ways. It is important to identify different dimensions of quality Garrin (1987) discusses eight components or dimensions of quality as follows. Performance (Will the product do intended job?) Reliability (How often does the product fail?) Durability (How long does the product last?) Serviceability (How easy is it to repair the products?) Aesthetics (How the product looks like?) Features (What does the product do?) Perceived Quality (What is the reputation of the company?) Conformance to standards (Is the product made exactly as the design indented?) Meaning of Quality Control Quality control is defined as Continue reading
Method Study
Method Study is a technique which analyses each operation of a given piece of work very closely in order to eliminate unnecessary operations and to approach the quickest and easiest method of performing each necessary operation; it includes the standardization of equipment, method and working conditions; and training of the operator to follow the standard method. The philosophy of method study is that ‘there is always a better way of doing a job’ and the tools of method study are designed to systematically arrive at this better way of doing a job. Method study is essentially used for finding better ways of doing work. It is a technique for cost reduction. Method Study may also be defined as the systematic investigation of the existing method of doing a job in order to develop and install an easy, rapid, efficient and effective and less fatiguing procedure for doing the same Continue reading
Important Aspects of Total Quality Management (TQM)
Total Quality Management (TQM) is a management philosophy that supports the process of continuous improvement within an organization and where total emphasis is placed on the customer. In the socioeconomic viewpoint, TQM defines the customer as all members of society and facets of environment that interact with the activities of the company. TQM is also defined as a set of management practices throughout the organization, geared to ensure the organization consistently meets or exceeds customer requirements. The goal of TQM philosophy is – “Do the right things right the first time, every time.” One of the principal aims of TQM is to limit errors to 1 per 1 million units produced. Total Quality Management (TQM) is a significant advance over traditional Quality Control (QC) programs. Traditional QC concerns itself with the number of final items found defective, replacing them with good items, or else negotiating the predicted failures into a supply Continue reading
