1 Describe the principles of Total Quality Management (TQM).
Answer: The basic principles for the Total Quality Management (TQM) philosophy of doing business are to satisfy the customer, satisfy the supplier, and continuously improve the business processes.
Satisfy the customer
The first and major TQM principle is to
2 List the seven basic quality control tools. Describe any three of them.
Answer: The Seven Basic Tools of Quality is a designation given to a fixed set of graphical techniques identified as being most helpful in troubleshooting issues related to quality. They are called basic because they are suitable for people with little formal training in statistics and because they can be used to solve the vast majority of quality-related issues.
3 Give the meaning of the following:
(a) Quality Circle
Answer: A quality circle is a group of workers who do the same or similar work, who meet regularly to identify, analyze and solve work-related problems. Normally small in size, the group is usually led by a supervisor or manager and presents its solutions to management; where possible, workers implement the solutions themselves in order to
(b) Continuous Improvement Process
Answer: A continual improvement process, also often called a continuous improvement process (abbreviated as CIP or CI), is an ongoing effort to improve products, services, or processes. These efforts can seek “incremental” improvement over time or “breakthrough” improvement all at once.[1] Delivery (customer valued) processes are constantly evaluated and improved in the light of their efficiency, effectiveness and flexibility.
(c) Reliability
Answer: Reliability may refer to:
- Human reliability
- Reliability engineering, the ability of a system or component to perform its required functions under stated conditions for a specified period of time.
- Reliability (psychometrics
(d) Business Process Reengineering
Answer: Business process re-engineering is a business management strategy, originally pioneered in the early 1990s, focusing on the analysis and design of workflows and business processes within an organization. BPR aimed to help organizations fundamentally rethink how they do their work in order to dramatically improve customer
(e) Poka Yoke
Answer: Poka-yoke is a Japanese term that means “mistake-proofing”. A poka-yoke is any mechanism in a lean manufacturing process that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur. The concept was
4 Define ‘Six Sigma Methodology’. What are the key roles in Six Sigma methodologies? Explain DMAIC methodology of Six Sigma.
Answer: Six Sigma is a set of techniques and tools for process improvement. It was developed by Motorola in 1986. Jack Welch made it central to his business strategy at General Electric in 1995.Today; it is used in many industrial sectors.
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing
- What is ‘FMEA’? Explain the concept of ‘Risk Priority Number’.
Answer: Failure Modes and Effects Analysis (FMEA) is a systematic, proactive method of evaluating a process. An FMEA identifies the opportunities for failure, or “failure modes,” in each step of the process. Each failure mode gets a numeric score that quantifies (a) likelihood that the failure will occur, (b) likelihood that the failure will not be detected, and (c) the amount of harm or damage the failure mode may cause to a person or to equipment. The product of these three scores is the Risk Priority Number (RPN) for that failure mode. The sum of the
6Write short notes on the following:
(a) Design of Experiments
Answer: In general usage, design of experiments (DOE) or experimental design is the design of any information-gathering exercises where variation is present, whether under the full control of the experimenter or not. However, in statistics, these terms are usually used for controlled experiments. Formal planned
(b) Just – In – Time (JIT)
Answer: Just in time (JIT) is a production strategy that strives to improve a business’ return on investment by reducing in-process inventory and associated carrying costs. Just in time is a type of operations management approach which originated in Japan in the 1950s. It was adopted by Toyota and other Japanese manufacturing firms, with excellent results: Toyota and other companies that adopted the approach ended up
