It aims to set a framework for minimizing issues and preventing defects before they arise through process design. This approach is a QC process involving inspecting and assessing all product parts.

Process vs product

That means checking product development or project outcomes to meet the previously defined quality standards. QC is a reactive process that responds to problems and aims to detect errors, such as software defects, glitches, or imperfections. This helps ensure you are producing a high-quality product before it reaches consumers. Organizations typically have a systematic approach to QCing products. Quality assurance is a broad concept in the life sciences industry.

In a bar graph-like structure, each bar within a histogram represents a group, while the bar height represents the data frequency. This diagram shows the connection between two variables by planning related data. The scatter diagram graphs pair numerical data with one variable on each axis to determine their relationship. The points will fall along the line or curve if the variables are correlated. Below you can see the integration of this time-tracking software with Trello. Moreover, our specialists customized seamless bundling with Trello to simplify the time-tracking process.

Unlike the definition Merriam-Webster’s dictionary provides, our version of quality doesn’t refer to “excellence.” Instead, it’s based on the expected needs of the customer. Inspection involves physically examining the deliverable for any defects to see if it matches the requirements. In statistical sampling, you select a random number of items from a batch and inspect them for defects and conformance issues. QC, meanwhile, involves measuring activities to verify the finished product before distribution. The key difference between QA and QC is that QA focuses on preventing defects and QC focuses on identifying weaknesses.

However, defect detection and remediation must still be recorded and executed in an organized method. Quality Assurance is popularly known as QA Testing, is defined as an activity to ensure that an organization is providing the best possible product or service to customers.
