The defects detection is the validation process. The defects prevention is a verification process.
defect prevention includes those strategies through which we avoid to occur a defect. for example formal risk analysis, prototyping. in defect prediction those areas are highlighted where there is possibility that defect can occur.
Acne prevention starts with a good acne system. Here is an article giving a review on a highly recommended system.

The periodic comprehensive review of a worker's health status to look for problems that may be occurring in the workplace that require targeted prevention is called medical surveillance

The defect count at which the review process is halted typically varies by organization and project. Common thresholds might be set at a specific number of major defects, such as three to five, or a percentage of the total items reviewed. If this threshold is exceeded, the review process is often paused to address the identified issues before proceeding. It's essential for teams to establish these criteria in their quality assurance guidelines to maintain a high standard of work.
Yes and it also helps with ticks.
A defect report typically includes several key fields such as a unique identifier (ID), a summary or title of the defect, a detailed description of the issue, steps to reproduce the defect, the severity and priority levels, the environment in which the defect was found, and any relevant screenshots or attachments. Additionally, it may include fields for the status of the defect, the person assigned to address it, and dates for reporting and resolution. This structured information helps teams track and manage defects efficiently throughout the software development lifecycle.
An underlying pathologic defect refers to a fundamental abnormality or dysfunction in the body's structure or function that contributes to a disease or health condition. This defect can be genetic, developmental, or acquired, and it often sets the stage for the manifestation of symptoms or complications. Identifying the underlying defect is crucial for diagnosis and treatment, as it helps healthcare providers target the root cause rather than just addressing the symptoms.
qa is set of activities whose purpose is to demonstrate that an entity meets all quality requirements. this is done by adopting a standard set of process and ususl qa techniques like review, training, facilitation etc. it can be termed as defect prevention qc is set of activities whose purpose is to ensure that all quality requirements are being met.this is defect detection, and done by testing Quality Control is mainly an inspection function. Quality assurance is an audit function. QA is process oriented Activity while QC is product Oriented Activity
You can use the defect density metric to track the number of defects found over a period of time. Defect density is calculated by dividing the total number of defects by the size of the software, usually measured in lines of code or function points. This metric helps in identifying trends in defect discovery and can inform quality improvement efforts.
