Control is a frequently used word, this lecture simplifies what a control is, the generic components of control process and its interactions. Control is universal only the control subjects vary. By the end of this lecture, learner understands and able to design a control feedback loop for any control subject.

Preview 05:39

There are varieties of control subjects such as cost control, production, inventory, budgets controls etc. Similarly Quality has always been a major control subject. This lecture describes the definitions of quality control as defined by renowned quality practitioners and the International Organisation for Standardisation (ISO) as well.

Preview 02:38

Control stations are the areas or a places where the control takes place. In this lecture, we will learn about the various control station locations that generally used by big industries. This will be helpful for the learner to decide the control station locations for their own industries.

Quality control involves a lot of decision making processes. Decisions following an inspections have long effects based on critical, usage and safety of product. Delegation of decision making is essential for effectiveness of quality control and assurance. This lecture is all about the delegation of decision making process of quality control.

Inspection
6 Lectures 18:12

Inspection and testing are the most important activities of quality control. This lecture provides an introduction of inspection, its objectives and the need of inspection and testing.

Introduction
04:31

This lecture talks about the different methods of categorizing the inspection, such as categorizing inspection by type, location, size etc.

Categories of inspection
04:21

This is an interesting lecture on decision of 'fitness for use' of a product. Items found not conforming to specification might at times be fit for use depending upon its usage, criticality and safety parameters. This lecture explain what is the differences between conformance to specification and 'fitness for use'.

Conformance to specification/fitness for use
05:11

This lecture talks about the classification of defects on the basis of seriousness. Every quality characteristics does not have same effect on fitness for use. Some are of serious and critical importance and many are minor. obviously, charcteristics which are critical deserve greater attention to quality.

Acceptance sampling 1
12 Lectures 41:27

The important aspects of Statistical Quality Control start from this lecture. Acceptance sampling is the process of evaluating a portion of the product from a lot for the purpose of accepting or rejecting a lot. This lecture provides the introduction to acceptance sampling.

Introduction
03:46

Acceptance sampling always carry some risks. There two major kinds of risks related to producers and consumers as part of the acceptance sampling. This lecture provides a good understanding about these risks and its associated terminologies.

Sampling risks and indices
05:06

Producer's risk or the type I error is the probabilty that a good lot will be rejected by a particular acceptance sampling. Producer's risk is always stated in conjunction with numerical index called Accepted Quality Level (AQL). This lecture explains the producer's risk and AQL.

Producers risk and acceptance quality level
04:06

Consumer's risk or the type II error is the probability that a bad lot will be accepted by a particular acceptance sampling. Consumer's risk is always stated in conjunction with numerical index called Limiting Quality Level (LQL). This lecture explains the consumer's risk and LQL.

Consumers risk and limiting quality level
03:20

Operating Characteristic Curve (OCC) is a graph that represents the probability of acceptance of a lot at different incoming quality levels. This lecture introduces the OC curve and how an ideal OC curve looks like.

Operating characteristic curve (OCC)
04:46

In this lecture, you will learn to identify the chance of acceptance of the lot at a particular level of incoming quality. Once we identify the chance of acceptance then it is easier to plot the probability of acceptance and lot quality in OC curve. Also learn how to find out the producer's / consumer's risks at a particular AQL / LQL.

Constructing OCC curve
06:29

Shape of and OC curve is affected by different sizes of lot, sample and acceptance number. In this lecture you will learn about these effects and identify optimum number of sample and acceptance number that gives an OC curve close to ideal.

Effect of lot size, sample size on OCC
04:20

Apart from the two common quality indices for sampling plans such as AQL and LQL, a third commonly used index is the Average Outgoing Quality Limit (AOQL). Learn more about AOQ and AOQL in this lecture.

Average outgoing quality limit (AOQL)
03:52

Based on the type of data of the control subject, inspection can be majorly classified as attribute and variable plans. Learn in this lecture about the various types of sampling inspection plans that will be useful to learners who wish to implement them in their respective organisation.

Types of sampling plans

Acceptance sampling 2
10 Lectures 34:39

Method of sample selection has a substantial influence on the result of inspection. A sample must be a true representation of entire lot. Random sampling method explained in this lecture significantly reduces the sampling biases.

Selection of random samples
05:10

Inspection is a non value added activity and add costs. Hence whenever it is known that the process quality has been improved; the level of inspections should also be reduced. In this lecture, the learner gains the standard method of switching from normal inspection to tightened or reduced inspections.

Normal, tightened and reduced inspections
04:57

This is the practical lecture on the implementation of standards discussed in previous lectures. ISO 2859 part I is the international standard for devising sampling plans for inspection by attributes. By the end of this lecture, the learner will effectively learn to devise a attribute inspection plans for his organisation.

Implementation of ISO 2859 standard
08:35

In this lecture, you will learn the various methods of variable sampling plans, basic statistic such as mean and standard deviation etc.

Sampling inspection by variables
04:21

In this lecture you will practically learn how to accept a lot in variable inspection plan when the standard deviation of the lot is known. This is will be helpful for organizations using variable sampling methods to inspect their product or processes.

In this lecture you will practically learn how to accept a lot in variable inspection plan when the standard deviation of the lot is not known. This is will be helpful for organizations using variable sampling methods to inspect thier product or processes.
