Quality Assurance vs. Quality Control: Choosing the Right Career Path

Quality assurance and quality control both fall under the umbrella of quality management. These jobs have similarities but also differ in many ways. The following guide will outline the roles of quality assurance and quality control professionals, including their skills, qualifications, salaries, and job outlooks to help you decide between the two career paths.

Quality assurance vs. quality control

Quality control is a reactive process that focuses on identifying and resolving issues that arise in the final product after it has reached consumers. Quality assurance is a proactive process primarily concerned with ensuring quality requirements are met before the product or service is released to the public. Quality assurance teams focus more heavily on development processes. In contrast, quality control activities center on the product. Since software development is an iterative process wherein products are consistently revised, updated, and patched, quality assurance teams working with software products may require reactive processes or quality control methods as well.

What is quality assurance?

Quality assurance (QA) is a set of activities and procedures, also known as quality standards, that take place during and after product development. QA helps ensure quality requirements are met and that the finished product or project outcome meets customer requirements. A QA testing team also seeks to solve problems experienced by consumers after a product or service hits the market. Like project managers, quality assurance teams ensure a project or product is advancing toward delivery while adhering to quality standards and company guidelines.

Why is QA important?

QA is important because it benefits an organization to have set guidelines and standards, such as those for training, documentation, monitoring, and audits during production. It’s a continuous effort to improve and ensure quality. QA guidelines also keep projects in scope and on track by aligning team members on collaboration practices and methods, such as code reviews in software development.

What is quality control?

Quality control (QC) focuses on monitoring results after a product is developed and produced. That means checking product development or project outcomes to meet the previously defined quality standards. Quality control activities are geared towards responding to problems and detecting errors or product quality issues such as software defects, glitches, or imperfections. The quality control process is a systematic approach that helps ensure service or product quality is maintained after it reaches the market.

Why is QC important?

QC is important because it identifies and corrects problems and defects as they occur to make sure that the final product is the highest quality possible. QC can involve software testing and beta or canary testing, which provide lessons applicable to future projects and products. Without QC, the organization can’t be sure that the product works as intended and suits the customers’ needs. A proper QC process leads to happier customers who have more incentive to be loyal to the company.
