What is Quality Assurance?

Quality assurance (QA) refers to the systematic measures implemented in manufacturing and service industries to ensure that the products delivered to customers fulfill the design, performance, reliability, and maintainability requirements agreed upon in the contract.

A good example of quality assurance in project management is when a company uses the ISO 9001 standard as its framework to ensure product and service quality. This standard contains requirements for all aspects of a quality management system, including customer satisfaction, risk management, and continuous improvement.

Why is Quality Assurance Important?

There are several reasons why quality assurance is important such as

1. Customer satisfaction: Maintaining consistent customer satisfaction is essential for establishing trust, preserving brand reputation, and nurturing customer loyalty towards products and services. Quality assurance aims to ensure high-quality outputs by closely monitoring and improving processes.

2. Regulatory compliance: Industries have set standards and regulations to ensure safety, reliability, and performance. Organizations use quality assurance to follow requirements, which reduces the risk of legal problems and penalties if they don’t comply.

3. Cost savings: Quality assurance enables organizations to identify inefficiencies, defects, and waste in the production process. By reducing these issues, organizations can optimize their resources, reduce costs, and improve profitability. Detecting and solving issues early can help businesses avoid costly recalls, reworks, and customer dissatisfaction.

4. Competitive advantage: Organizations that give more importance to quality assurance have a greater chance of providing better products and services, which can make them stand out among their competitors. This benefit can result in a larger portion of the market, improved customer loyalty, and sustained success in the long run.

5. Continuous improvement: The process of quality assurance helps in fostering a culture of constant improvement by recognizing weak areas and implementing corrective measures. Constantly evaluating and refining processes improves performance, productivity, and overall effectiveness.

All in all, quality assurance is an essential aspect of maintaining high standards, ensuring customer satisfaction, and achieving organizational success.

5 Types of Quality Assurance

Process

The various quality assurance methods are

1) Failure testing

Failure testing ensures that the product or service does not fail or break. It is conducted at regular intervals to determine that the process is being conducted correctly. Some products need to withstand stress and here the process involves testing the said product under vibration, pressure, or heat. If it is a software product, then the method of failure testing consists of placing the software under high load or usage conditions.

2) Total quality management or TQM

Total Quality management relies on analysis, data, and facts to support performance reviews and product planning. Total quality management or TQM takes the help of quantitative methods for continuous improvement.

3) Statistical process control or SPC

Statistical Process is described as a methodology that is based on objective analysis and data. Statistical process control or SPC uses statistical methods to control and manage the manufacturing of products.

4) Process and Product Quality Assurance (PPQA)

Process and Product quality assurance is a systematic approach to ensure that processes that are involved in product creation as well as the product itself meet the standards and requirements of the industry or the quality standards set by the manufacturer. The objective of PPQA is to prevent defects, improve overall efficiency, and deliver higher-quality results.

5) Capability Maturity Model Integration (CMMI)

Capability Maturity Model Integration, or CMMI for short, is an effective quality assurance method used in software development. This model begins with assessing the current maturity level of your business and then training your team to guide you through each successive stage until a reliable quality assurance process has been established.

Quality Assurance vs Quality Control

Grounds of ComparisonQuality Assurance (QA)Quality Control (QC)
ObjectiveQA is a proactive process aimed at preventing defects with a focus on the process used to make the product. It's a systematic approach to determine whether the quality procedures are effective and being followed.QC is a reactive process and it comes into the picture when the product has been produced. It's a systematic approach to identifying defects in the finished products and ensuring they are corrected.
FocusQA focuses on processes and aims to prevent defectsQC focuses on the product, aiming to identify and correct defects.
What it doesQA plans the necessary guidelines to deliver a quality product and sets the standards and methodologies to meet customer requirements.QC checks whether the product meets the standards and guidelines defined by the quality assurance process.
When it happensQA activities are performed before production.QC activities are performed after production.
ResponsibilityQA is the responsibility of the entire team.QC is typically the responsibility of specific team members who test the product for defects.

Quality Assurance and Quality Control – both play an integral role in guaranteeing product quality, though they differ significantly. QA involves a proactive approach to risk management by preventing errors during production. Conversely, QC takes place after the service or good has been produced; it is centered on testing output for defects.

What are the Advantages of Quality Assurance?

1. Optimized consumer satisfaction: This involves making sure that goods and services live up to or even exceed customers’ expectations, which in turn promotes customer contentment, brand loyalty, and trust.

2. Cost reduction: The quality assurance process involves locating and eliminating waste, errors, and inefficiencies throughout production. As a result, expenses are reduced, profitability rises, and resources are used more effectively.

3. Regulation and standard compliance: Adhering to established quality assurance standards and frameworks is crucial since it aids firms in meeting legal requirements, lowering their legal risks, and improving their reputation in the target market.

4. Continuous improvement: By identifying areas of weakness, taking remedial action, and refining processes to improve overall performance and efficiency, quality assurance contributes to the development of a culture of continuous improvement.

5. Competitive advantage: Organizations that prioritize quality control are more likely to deliver superior goods and services. Long-term, this may result in more market share, higher client retention rates, and better success.

Quality Assurance Principles

Quality assurance relies on two fundamental ideals: “fit for purpose,” ensuring the product/service is suited to its primary use, and “right first time,” which rectifies any errors before they have a chance to occur. By adhering to the aforementioned two fundamentals, we aim to ensure that our product or service is functioning properly continuously by controlling project conditions. Quality assurance entails the administration of raw materials, products, and components’ quality; services associated with production; in addition to overseeing, manufacturing, and inspecting procedures.

History of ISO and QA

Quality assurance has been around since the Middle Ages, but it wasn’t until World War II that its importance was particularly highlighted.

During this period, there was an enormous demand to inspect high volumes of munitions produced in the United States, which made QA practices even more essential. Established in Geneva in 1947, the ISO issued its first standard in 1951 concerning industrial reference temperatures for measurements.

As their influence rose exponentially, so did their scope of standards and regulations. The ISO 9000 family of standards has been available to the public since 1987. Each standard, identified by a unique number, guides different situations and needs.

Quality Assurance Standards

As the times evolve, so must Quality Assurance standards to remain applicable and useful for today’s businesses. ISO regulations should undergo regular updates to keep up with current trends and industry needs.

Leaders in the industry are now turning to ISO 9001:2015 for guidance. This version is an upgrade; it provides a more customer-centered approach and helps leaders understand how to transform their companies with top management practices, as well as stay up-to-date on advancements.

In addition to making general enhancements, ISO 9001:2015 features an improved structure and greater insights into risk-based decisions.

QA Certifications

There are several quality assurance certifications available to ensure that organizations comply with the set standards. Customers make this certification qualifying criterion before selecting the required product or service. Some important certifications are –

1. ISO 9000

The ISO or International Organization for Standardization is responsible for mapping the processes that are used for the implementation of quality assurance.

Most organizations use ISO 9000 to ensure an effective quality assurance system is in place. This standard was established in the year 1987 and its objective is to verify and review whether the company is following the processes and checking whether it needs any improvements.

An organization that wishes to receive this certification has to be audited based on its operations, services, products, and functions. The ISO 9000 certification helps in

  • Offering the best available customer services
  • Minimizing waste
  • Boosting the productivity of the employees
  • Making improvements in both international and domestic trade
  • Increasing the profit of an organization

2. CMMI Levels

The CMMI or Capability Maturity Model Integrated has been specially developed for improvement in software processes.

This process improvement approach has been based on the process-maturity framework and is used in the software industry to assist in business processes.

It has found high acceptance in software development organizations. The companies who wish for the CMMI certifications are certified from 1 to 5 levels based on their mechanisms. These levels are

  • Level 1 – (Initial) – This is the initial level of CMMI certification, and has no documentation and processes that have been followed till now; the quality environment is considered unstable.
  • Level 2 – (Repeatable) – This is known as the repeatable level or Level 2 of CMMI certification. It ensures all the processes are followed at the required project level.
  • Level 3 – (Defined) – This is known as the Defined level or level 3 of CMMI certification. Here the processes are documented and defined at the organizational level and are subject to some improvement
  • Level 4 (Managed) – This is known as the Managed level or Level 4 of the CMMI certification. It uses process metrics to control the processes
  • Level 5 (Optimizing) – Level 5 or Optimizing the level of CMMI Certification puts its onus on continuous improvement of the processes

3. Test Maturity Model

The Test Maturity Model or TMM assesses the process maturity during the testing environment. It has five levels

  • Level 1 (Initial) – At this level ad-hoc method is used, and you will not find a quality standard for testing processes
  • Level 2 (Definition) – This level defines procedures and prepares test cases, plans, and test strategies
  • Level 3 ( Integration) – In this level, testing is carried out in the full software development cycle
  • Level 4 ( Management and Measurement) – This level reviews designs and requirements
