Quality Assurance vs. Quality Control | QA vs QC | Difference between Quality Assurance and Quality Control | Shakehand with Life

Quality Assurance and Quality Control
Difference between QA and QC
Quality Assurance and Quality Control both are different from each other in many aspects such as definition, focus, objective, execution, and many more. If you're working as a quality professional in the manufacturing or service industry then you must be aware of the difference between the two. 

Before we understand the meaning of 'Quality Assurance' and 'Quality Control', we need to understand the meaning of 'Assurance' and 'Control'.

Assurance

Assurance stands for a promise, a belief, or confidence. It is like a positive declaration, a manual, a plan, or an agreement intended to give confidence. It represents the plan of action. e.g. Showcasing a driving license to a traffic inspector provides the confidence to the inspector that the driver can able to drive the car.

Control

Control stands for the activities to manufacture a product within the specified limits or sustain a process with the lowest possible variation. e.g. control over the steering of the car, brakes, clutch, and gear for the smooth run of the car. Similarly, we can consider 100% inspection, random inspection, verification, and validity testing are a few activities of control that help to maintain and sustain the quality of the product.

What is quality?

Quality is the ratio of performance to expectation. 

So if Q=(P/E) where 'P' is performance, 'E' is the expectation and naturally 'Q' is quality.

It is expected that an organization shall deliver a maximum of 1% defective parts in every lot.

  • Now if the organization delivers more than 1% defectives that means the organization's manufacturing process has some problem and the performance of the process is not expected, and therefore the quality of the process is below par.
  • If the organization delivers exactly 1% defectives as expected then the customer perceived the quality of the process of the organization is at par i.e. performance is the same as expected.
  • If the organization delivers less than 1% defectives then, in that case, the quality of the process of the organization is above par i.e. the performance is greater than expected.

Hence the Quality Assurance includes the plan of action to control the quality or the performance of the process.

Quality Control is the bunch of activities that can control the quality or the performance of the process actually.

Difference between QA and QC under different contexts.

Definitions of QA and QC as per ISO9001

QA: A part of quality management focused on providing confidence that quality requirements will be fulfilled. It relates to how a process is performed, or how a product is made.

QC: A part of quality management focused on fulfilling quality requirements. It is more the inspection aspect of quality management

Functional Definitions

QA: All the planned and systematic activities are implemented within the quality system that can be demonstrated to provide confidence that a product or service will fulfill requirements for quality such as product or process audit.

QC: Operational techniques and activities are used to fulfill requirements of quality while manufacturing a product such as inspection and testing of the product

Evolution

QA: 1950s; The quality profession expanded to include the quality assurance and quality audit functions.

QC: 1920s; Following the industrial revolution and rise of mass production. It became important to define and control the quality of products in a better way.

Focus

QA: Focus on planning and documenting the processes to assure quality such as quality plans, inspection plans, and test plans.

QC: Focus on physical verification that the product conforms to these planned arrangements through inspection, measurement, and testing.

Key Activities

QA: Development of quality plan, development of inspection plan, development of SOPs, evaluation of the quality system through audits, preparation of documents for QMS, etc.

QC: Implementation of the quality plan, follow the inspection plan and SOPs, control the quality of product through inspection, and implementation of QMS as per the documentation, etc.

Objective

QA: Prioritize the customer requirements and translate them into technical requirements for product development with the help of the engineering team using quality function deployment.

QC: Inspect the technical requirements of a product or service and conform against the specifications to meet the customer requirements using measuring, examining, and testing one or more characteristics.

What they do?

QA: Prevent the quality problems through planned and systematic activities including documentation, SOPs, control plan, inspection plan, quality plan, FMEA, etc.

QC: Achieve and maintain the quality of product, process, and service using activities and techniques including 100% inspection, measurements, gauge R&R, Attribute R&R, etc.

How they do?

QA: Establish a good quality system and assessment of its adequacy through conformance audit of the operating system also the review of the system itself using product audit, process audit, and system audit.

QC: Find and eliminate the causes of quality problems so that customer requirement is continually met and the tools used for this purpose include; Why-Why analysis, cause and effect diagram, What is-What is not, etc.

Defect Control

QA: Predict potential defects right from the product development and process design, categorize the defects like critical, major and minor and establish a quality system that could prevent the occurrence of the defects such as prototype testing, Failure Mode Effect Analysis (FMEA), etc.

QC: Identify the defects and defectives through in-process inspection, sorting of defective parts through 100% inspection, and implement the inspection plan to prevent the escape of defective parts such as final inspection as per AQL.

Performance Evaluation

QA: Evaluate the performance of the product against a system, standard, or specified requirements for customers. e.g. Evaluation of the performance of a tyre with a particular car.

QC: Ensure the job management, competence, and performance during the manufacturing of the product or service within the system to ensure it meets the quality plan as designed e.g. testing the performance of a tyre while manufacturing.

As a Quality Tool

QA: Way of management, it is a complete system including the control also to assure the quality of the product or service. 

QC: It is a process itself and part of the QA, just measures and determines the quality level of the products or services.

Overview

QA: It is a process-centric and proactive approach. It is a staff function that uses the 7 new QC Tools. It prevents the defects with help of quality audits and quality tools.

QC: It is a product-centric and reactive approach. It is a line function that uses 7 basic tools for process improvement. It finds the defects by a walk of the process, testing, and inspection.

Quality Function Deployment: Introduction to House of Quality, Aspects, Need, Evolution and QFD Teams

For every organization, customer satisfaction is the primary focus, so to achieve customer satisfaction it is mandatory for an organization to capture the voice of the customer clearly and so identifies the resources to manufacture a product in which the voice of the customer could be clearly reflected. But to capture the voice of the customer and then translate it into the product is quite difficult if not impossible. So if the requirements of the customer are not captured clearly then an organization never be able to produce a product according to the expectations of the customer. Here the Quality Function Deployment plays a vital role in the process of translating the customer requirements into the final product.

Quality Functional Deployment

Quality Function Deployment is a planning tool to fulfill customer expectations through product design, engineering changes, and production process. QFD is really an effective quality tool that translates the voice of the customer into the final product. 
QFD first initiated by Dr. Mizuno, who was a professor at the Tokyo Institute of Technology, Japan, and the first application of QFD was in 1972 at Mitsubishi Heavy Industries, Ltd. in the Kobe Shipyard Japan. 
QFD supports an organization to improve the engineering knowledge of the employees, productivity, and quality of the product and service and reduce the production costs, product development time, and engineering changes.

House🏠 of Quality

The house of quality is a significant part of the quality function deployment. An organization builds the structure of the house of quality for new product development. The house of quality has different sections/rooms for different objectives concerning customer requirements and technical requirements.
Quality Function Deployment | House of Quality

Customer Requirements: Room1

This section is like the entrance of the house and assigned for the customer requirements or the voice of the customer also known as WHATs categorizes the customer requirements into primary and secondary level.

Technical Descriptors: Room2

This section is on the first floor of the house and assigned for the technical descriptors or the voice of the organization also known as HOWs categorizes the technical requirements into primary and secondary level.

Relationship Matrix: Central Hall

In this section which is considered the central hall of the house, the QFD team studies the relationship between customer requirements and technical requirements like how closely the customer requirements are related to the technical requirements (WHATs vs HOWs)

Interrelationship Matrix: Room3

This section is on the top of the house, here the QFD team studies the interrelationship between technical descriptors like how the material of the product affects the process of manufacturing of a product (HOWs vs HOWs)

Customer Competitive Assessment and Prioritized Customer Requirements: Room4

This section is the backyard of the house, here the QFD team calculates the customer competitiveness of our product in the market compared to the competitor's product and also prioritizes the customer requirements on the basis of absolute weight and percent score.

Technical Competitive Assessment and Prioritised Technical Descriptors: Room5

This section is at the bottom of the house, here the QFD team calculates the technical competitiveness of the product and the higher ranking of the product shows the engineering superiority of the product compared to the competitors' product and also prioritizes the technical descriptors.

Aspects of  Quality Function Deployment

Quality Function Deployment has two aspects 1. Quality Deployment, 2. Function Deployment

Quality Deployment

Quality deployment means translating customer requirements into product design requirements, it is a creative approach for example; the realization of the customer expectations into the design of the mobile device such as reasonable cost, nice finish, durability, feather touch, fine grip, lightweight, medium size, user friendly, etc.

Function Deployment

Function deployment means translating the product design requirements into product, parts, and process requirements, it is an action approach for example; realization of a mobile device as per design of the mobile device, planning for material procurement to manufacture the mobile device, developments of the parts like Cabinet of mobile device, PCB, ICs, Camera, Screen, Softwares, Wifi, Bluetooth, etc. Planning of the process of assembling the parts of the mobile device such as soldering, surface mounting, embedded system, etc.

Evolution of Quality Function Deployment

  • 1977: The evolution of QFD started with the implementation of QFD at Toyota manufacturing with the production of Mini-Vans
  • Oct. 1979: Toyota reported a 20% reduction in start-up costs in the launch of a new Van.
  • Nov. 1982: Toyota reported a 38% reduction in start-up costs.
  • April 1984: Toyota reported a cumulative 61% reduction in start-up costs
  • 1984: QFD introduced to the United States of America in Xerox Inc. by Dr. Clausing

The Need of QFD for an Organization

QFD helps an organization in many ways and become the need of the hour as mentioned below
  • Protects the voice of the customer and ensures that the voice of the customer is being heard.
  • Identifies the conflicting requirements like increasing the resolution of the camera of a mobile device without increasing the cost of the mobile device and ensures that the conflicting requirements are resolved before the production
  • Controls the voice of the organization to enter into the product design adversely it implies, the organization always takes care of the customer requirements and never change the design of the product on its own without taking the consent of the customer to invite the customer dissatisfaction.
  • Directs the QFD team to design the product as expected by the customer
  • Focuses on the need of the customer and hence avoids the improvements that customer doesn't want.
  • Guarantees to implement the voice of the customer into the final product or service.
  • Saves the time to design or redesign and modification of the product by one-third to one-half of the time taken by traditional means.
  • Reduces the development costs.
  • Saving the time to design a new product can help an organization to push the product into the market earlier than expected.

QFD Teams

QFD teams are of two types; 1. The New Product Design Team, 2. Existing Product Modification Team

The New Product Design Team

  • Translates the customer requirements into new product design for example design of a new smartphone as per the customer requirements.
  • Members of the team are from Marketing, Design, Quality, Finance, and Production.
  • Members of the team might be from the customer side to provide the inputs for customer requirements
  • Members of the team might be from the supplier side to provide the inputs for the design requirements and product planning.

The Existing Product Modification Team

  • This team identifies the modification opportunities in the product through the assessment of the market performance of the product.
  • For example; modification of the camera resolution and processor up-gradation of a mobile device.
  • Fewer members are required in this team because of modification work only

Two-Tailed Test for Hypothesis Testing in Statistics, Research and Lean Six Sigma

Hello everyone,
In this blog, we'll study a two-tailed test in the context of hypothesis testing. So far with respect to hypothesis testing, we have studied,

Testing a Hypothesis

For testing a hypothesis we have three different situations

Case 1: H0: μ=μ0 and Ha: μ not equal μ0

When the null hypothesis stated as the population mean equals to the hypothetical population mean and alternative hypothesis stated as the population mean is not equal to the hypothetical population mean. It implies the population mean is either lower than or higher than the hypothetical population mean

Case2: H0: μ=μ0 and Ha: μ < μ0

When the null hypothesis stated as the population mean equals to the hypothetical population mean and alternative hypothesis stated as the population mean less than the hypothetical population mean

Case3: H0: μ=μ0 and Ha: μ>μ0

When the null hypothesis stated as the population mean equals to the hypothetical population mean and alternative hypothesis stated as the population mean greater than the hypothetical population mean

Now In case 1, we use two-tailed test to test the null hypothesis and in two other situations we use a one-tailed test such as left-tailed test and right-tailed test for case 2 and 3 respectively

Rejection Regions, Acceptance Region, and Critical Limits

In a two-tailed test, there are two rejections regions also known as critical regions, one on each tail of the curve. For a 5% significance level, the value of alpha (α) is 0.05. it defines the probability of the rejection area for the null hypothesis when it is true. And if we apply the two-tailed test, then it equally splits on both sides of the curve such as (α/2)=0.025

Now the acceptance region is 95% or 0.95, here in this region the null hypothesis will be accepted. The acceptance region is the area under the normal curve between the critical limits defined by Z=+/-1.96 at a 5% significance level. You may name these limits as lower critical limit and the upper critical limit for suitability

Now the area under the left half of the curve up to the lower critical limit Z= -1.96 is 0.475 and the area under the right half of the curve up to the upper critical limit  Z=1.96  is also 0.475 and both taken together equals to 0.95 or 95% area of the curve.

Now to find the area under the normal curve for Z=1.96, you may refer the table “Area under the standard normal distribution”  in any book of business statistics

Here 1.96 is the critical value, and if the value of test statistic like ‘Z’ test comes out less than  or equal to1.96  then the null hypothesis will remain in acceptance region and if the value of test statistic comes out above 1.96 at 5% significance level then the null hypothesis will rest in the rejection region.

Hence mathematically Acceptance Region is defined by;
A: |Z|<=1.96
And Rejection Region is defined by;
R: |Z|>1.96

Now to better understand the concept of the two-tailed test, let's take an example

Example Problem

A sample of 400 male students is found to have a mean height of 67.47 inches. And the mean height of a large population of male students is 67.39 inches and the standard deviation is 1.30 inches. Conclude that at a 5% significance level, whether the sample is taken from the population having a population mean 67.39inches.
Now to conclude that whether the sample is taken from this population at a 5% significance level, we first state the null and alternative hypothesis…..

Solution

So the null and alternative hypothesis for the given problem can be stated as
H0: μ=67.39 and Ha: μ not equal 67.39
Here alternative hypothesis is two-sided hence we use two-tailed test, also it is given that
  • The sample mean (xbar)=67.47inches,  
  • The hypothetical population mean (μ0)=67.39 inches, and 
  • Population standard deviation (Std. Dev.p)=1.30 inches
  • And Number of students in sample (n) = 400
Now let's process the z test by replacing the value of  x bar, mu not, sigma p, and N in the z statistic, assuming the population to be normal
Z= (xbar-μ0)/(Std. Dev.p /sqrt(n)
Z= (67.47-67.39)/(1.30/sqrt(400) = 0.080/0.065=1.231
The calculated value of ‘Z’ is 1.231 less than the critical value of Z=1.96 at a 5% significance level under a two-tailed condition hence it will lie in the acceptance region and therefore null hypothesis is accepted.
And we may conclude that the given sample with mean height of 67.47 Inches drawn from the population with a mean height of 67.39 inches and a standard deviation of 1.30 inches at a 5% significance level.

Prevention of the Community Transmission of COVID-19 using 5S Methodology

Hello everyone,
In this blog, we are going to study, how to prevent the community spread of COVID-19 using 5S. But first, let me remind you the 5S, The 5S are Sort, Systemize, Sanitize, Standardization and Sustain

1. Sorting

Now let's begin with Sort. Sort implies an organization of necessary and unnecessary things for us. So here in the case of COVID-19, we’ll study what are necessary for us and what we must avoid stopping the transmission of COVID-19.

Dos

First talk about the necessary things to do
  • Stay at home and work from home
  • Follow the social distancing
  • Wash hands with soap and water for 20 seconds
  • Cover your nose and mouth while sneezing or coughing with tissue paper or your own elbow
  • See a doctor if you feel fever, dry cough, and breathing problem, and also isolate and quarantine yourself for 14 days as a preventive measure to stop the transmission of COVID-19
  • Filter the information coming to your phone in the form of video, text or graphics
  • Share only, if the information is valid and the source is confirmed

Don'ts

Now things we must avoid to do, to prevent the transmission of COVID-19 are
  • Don’t be the part of a gathering
  • Don’t spit in public
  • Don’t touch your nose, mouth, and eyes
  • Don’t ignore the symptoms like fever, dry cough, and breathing problem
  • Don’t leave home to go outside in case you are sick
  • Don’t handshake with anyone, especially if you are experiencing cold and fever
  • And Don’t believe in rumors

2. Systemization

Now come to 2nd ‘S’ the Systemization or ‘Set the things in an Order’
  • Keep the soap and sanitizer in the washroom at an optimum level to wash the hands frequently for 20 seconds daily.
  • Keep the mask or handkerchief at a place where you can get it easily
  • Keep the tissue paper in your pocket and throw it in a covered dustbin after use...
  • Make the list of people u are meeting daily to track your 14 days history until we overcome this life-threatening challenge of COVID-19
  • Stay at a distance of 1-2 meters while gathering at the workplace if not possible to avoid.

3. Sanitization

Now come to 3rd ‘S’ the Sanitization’, to prevent the transmission of COVID-19 the role of sanitization is utmost important and it includes;
  • Washing hands with soap and water for 20 seconds or sanitize with an alcohol-based sanitizer
  • Sanitize the items at the workplace like table-tops, laptop, paper tray, pen holder, etc.
  • Sanitize the toys of the children and avoid kissing them.
  • Sanitize the things which are being commonly used or touched frequently by the people at the workplace like meeting rooms, desktops, door handles, water taps, bathrooms, etc.
  • Sanitize your mobile phones and avoid sharing it with other people.
  • And the most important, sanitize the information to avoid rumors by deleting videos, text, and graphics which are coming from untrusted and unknown sources and which you can’t verify personally

4. Standardization

Now come to 4th  ‘S’ the Standardization,  The standardization ensures the standard practice of  first 3S and visual management and it includes in case of prevention of covid19 transmission
  • Place a chart in washroom or workplace to monitor the handwashing frequency in a day
  • Place a chart to track the body temperature in the morning.
  • Place a chart at the place of workout to track your daily exercise
  • Place a chart in the kitchen to track the balanced diet for breakfast, lunch, and dinner to improve immunity
  • Place the chairs at a 1-meter distance in the drawing-room, balcony, garden, and on the terrace to practice social distancing at home and workplace
  • Place a chart to track the 14 days history that showcases, the place and person you met with
  • Visit only WHO website, who.int and the website of the ministry of health and family welfare, mohfw.gov.in as the standard source of information with respect to the COVID19 pandemics.

5. Sustain

Now come to 5th  ‘S’ the sustain, and it means habit formation and it includes;
  • Do the daily exercise for 30 minutes like yoga, aerobics, jogging, and dancing.
  • Make it a habit to wash hands for 20 seconds with soap and water before every meal like breakfast, lunch, and dinner
  • Make it a habit to use the tissue paper or your own elbow while sneezing or coughing
  • Practice to avoid touching your mouth, nose, and eyes as much as possible
  • Practice safe greetings like Namaste, wave, nod, or a bow
  • Practice to talk with the people at a distance of 1 meter 
  • Practice avoiding to visit in crowded places.
  • Develop creative skills like writing, painting, cooking, stitching, etc. while staying at home.
  • Develop the habit of reading the books rather read the long messages in WhatsApp and see the meaningless videos
  • Learn from past, stay in present and plan for the future to make yourself ready to face this kind of life-threatening challenge.
  • And Practice spreading the love…. not the COVID-19 and hatred
