quality assurance refers to activities associated with guaranteeing the quality of a product or service. quality control is based on the scientific method, which includes the phases of analysis, relation, and generalization.
The inputs to the quality assurance process are:Output from quality planning - The following output items from the quality planning process become the input to the quality assurance process:• Quality management plan - This plan is the output of the quality planning process, and it describes how QA will be performed for this project.• Quality metrics - A quality metric is an operational criterion that defines in specific terms what something (such as a characteristic or a feature) is and how the quality control process measures it. The quality metrics developed during quality planning, such as defect density, failure rates, reliability, and test coverage, must be employed during QA.• Process improvement plan - The process improvement plan, helps improve the quality of the project and must be implemented during QA.
A job description provides the quality assurance professional with the list of tasks performed in a particular job and the performance steps (procedures) required to perform each of the tasks.
Quality ControlEmphasizes testing of products to uncover defects, and reporting to management who makes the decision to allow or deny the release.Quality AssuranceAttempts to improve and stabilize production, and associated processes, to avoid, or at least minimize, issues that led to the defects in the first place.

different between quality control & quality assurance
A
The main processes in Project Quality Management are: quality planning and assurance, quality control and quality improvement
The three spheres of quality are: Quality Managament Quality Assurance Quality Control
Quality assurance is the end result of a good quality control system. Basically, quality assurance means that the end user (customer) can be assured that the goods/service he paid for will be of high quality.
The quality assurance by PDSA cycle ensures that quality control, quality management system and construction process is maintained.
Quality assurance (QA) - Quality assurance is the process of auditing the results from quality control measurements to ensure that the quality requirements are being met. This process is used during the execution of the project. In most cases it is used alongside quality control. Quality control - This refers to monitoring and controlling the project results to ensure they meet the agreed-upon quality standards
* QA = Quality Assurance * QC = Quality Control
Clearly, there are marked differences between quality guarantee and quality control. Assurance of quality is a set of preventive activities, which are focused on processes whereas quality control is a detection activity, which is focused on detecting the defects once the product is manufactured. Assurance defines the standards to be followed in order to meet the customer requirements whereas quality control ensures that these defined standards are followed at every step. This is done by conducting various tests and checks. Based on these tests and checks, the quality control prepares regular reports that act as an input to the assurance of quality department which then reviews the same and decides on the corrective and preventive actions required in the processes.

Advantages of quality control: Ensures products meet standards, reduces defects, and maintains consistency. Disadvantages of quality control: Reactive approach, does not prevent issues, and can be costly. Advantages of quality assurance: Prevents issues through process improvement, promotes a proactive approach, and enhances customer satisfaction. Disadvantages of quality assurance: Requires ongoing monitoring and adjustment, can be time-consuming, and may not eliminate all potential problems.
