Quality assurance in its broadest form can be defined as the set of actions that companies take to be able to provide goods and services to consumers with the expected level of quality.

The application of a quality assurance system generates confidence and assurance for companies that their products will meet the appropriate conditions of expected quality.

Therefore, to this end, they apply quality standards as part of a system that allows the development of the organization, direction, and control of the entire process.

It can also be said that managed software testing services is an audit that verifies that quality standards are met, that is, it checks that all the minimum requirements expected in the product are met.

Secondly, for companies to comply with quality assurance, they must follow a line of actions previously planned, systematized, and finally implemented in the form of a set of standards that the company must follow.

However, quality assurance requires that all processes be documented; both planning, determining tasks and responsibilities, recording results, and all control mechanisms that are applied within each company.

How Quality Assurance Was Born?

How Quality Assurance Was Born

In fact, quality assurance first appeared as an important element of companies' production operations during the 1920s.

Since then, Walter Shewhart, who was one of the first to develop control cards, has been considered the initiator of this system. The same goes for Harold Dodge who developed sampling techniques and George Edwards with his contribution to economic analysis techniques to solve problems.

Thus, these three characters formulated new inspection methods and theories focused on maintaining and improving quality, which they did when they were transferred from Western Electric's inspection service to Bell Telephone Laboratories; These contributions are considered the basis of what is called quality assurance.

What Benefits Of Quality Assurance Can You Get?

What Benefits Of Quality Assurance Can You Get

1. Avoid waste and reduce costs

On the one hand, avoiding the appearance of waste is achieved because the insurance system improves the company's productivity, because it allows it to better focus on achieving the objectives and what customers expect from the quality of the product.

In addition, waste can be reduced or disposed of because it is possible to identify activities that only increase costs and do not value the process, in the same way as it promotes the achievement of efficiency.

2. Improved quality and customer satisfaction

Similarly, continuous improvement makes it possible to improve the quality of the products delivered to the customer, which gives the necessary confidence that the desired quality is achieved and maintained, because everything is documented and certified.

As a result, the company will get satisfied customers, which encourages them to increase their purchasing frequency and recommend the products to other people, generating higher sales revenues and, of course, higher profits.

Components Of The Quality Assurance System

Components Of The Quality Assurance System

The quality assurance system includes the following elements:

1. Administration Manual

Of course, a project management manual includes important data that must be taken into account to be used in each company's quality management plan, so specific procedures are defined to achieve objectives in a specific way for each organization, usually with the help of a quality management software.

2. Quality control measures

Of course, quality control measures establish the degree or level of quality achieved in each activity evaluated as part of the process. Be able to use criteria such as performance within the set deadlines, compliance in the execution of budgets, and the frequency of errors or defects in the process, among those that could be mentioned.

3. Reports on the performance obtained

On the other hand, reports on the performance achieved must be prepared periodically throughout the development of the different parts of the project, as this will monitor how all activities are carried out and avoid higher costs, if only the final process is inspected.

Above all, it is possible to assess whether deadlines are met, based on the schedules already prepared, the progress of the delivery process, technical performance, and any activity that involves costs.

Quality Assurance: FAQs

Quality Assurance (QA) is a crucial process that ensures a product or service meets the desired standards for functionality, usability, and overall excellence. Here are some commonly asked questions about QA:

What is the difference between Quality Assurance (QA) and Quality Control (QC)?

  • QA focuses on preventing defects by establishing processes and procedures throughout the development lifecycle. It's proactive and ensures quality is built into the product from the beginning.
  • QC focuses on detecting defects through testing and inspections. It's reactive and identifies issues that need to be fixed.

What are the benefits of implementing Quality Assurance?

  • Reduced costs: Catching defects early in development is cheaper than fixing them later.
  • Improved product quality: QA helps ensure your product meets customer expectations and functions as intended.
  • Enhanced customer satisfaction: High-quality products lead to happier customers.
  • Increased efficiency: QA helps streamline development processes and avoid rework.
  • Improved brand reputation: Delivering quality products strengthens your brand image.

What are the different types of Quality Assurance activities?

  • Requirements gathering and analysis: Ensuring clear and well-defined requirements for the product.
  • Test planning and execution: Creating and running tests to identify bugs and ensure functionality.
  • Defect tracking and management: Logging, reporting, and resolving identified issues.
  • Risk management: Identifying potential risks and implementing strategies to mitigate them.
  • Audits and reviews: Evaluating processes and procedures to ensure effectiveness.

Who is involved in Quality Assurance?

QA can involve various roles depending on the organization:

  • QA Testers: Execute tests and identify defects.
  • QA Analysts: Design and develop test plans and strategies.
  • Software Developers: Work closely with QA to fix identified bugs.
  • Project Managers: Ensure QA activities are integrated into the development process.

What are some common QA tools and methodologies?

  • Testing frameworks: Provide structure and automation for test execution (e.g., Selenium, Cypress).
  • Bug tracking systems: Facilitate reporting, tracking, and managing defects (e.g., Jira, Bugzilla).
  • Version control systems: Track changes and manage different versions of the product (e.g., Git).
  • Agile methodologies: Promote iterative development with continuous testing and feedback (e.g., Scrum, Kanban).

How can I get started with Quality Assurance?

There are several ways to get involved in QA:

  • Online courses and certifications: Many resources offer training and certifications in QA methodologies and tools.
  • QA internships: Gain practical experience by participating in internship programs.
  • Start by testing your own software: Develop critical thinking and problem-solving skills by testing applications you use daily.

A Final Word

In conclusion, we can say that qa as a service brings many benefits to companies, especially in terms of reducing costs, delivering products of the expected quality, and, above all, satisfying their customers.

Since this system makes it possible to document the processes to maintain the delivery of products and services with the expected quality, it must always be constantly reviewed and updated periodically, as continuous improvement must always be sought.
