A person who is asked this will need to provide an answer based on their personal experience. Indicating a specific incident where they have done well at using analytical work to ensure quality assurance and control and how they would also use this for the current job would be helpful.

An audit is performed by an outside party; a control is exercised by an internal party. A control provides assurance to management, while an audit provides assurance to outside investors.
A
different between quality control & quality assurance
From my experience in QA, this is one of the most common misconceptions in the field - people think Quality Assurance and Quality Control are the same thing. They're absolutely not, and understanding the difference is crucial for anyone working in software development. Quality Assurance (QA) is proactive - it's about preventing defects before they happen. QA focuses on establishing processes, standards, and procedures that ensure quality is built into the product from the beginning. Think of it as creating a framework that makes it nearly impossible for bad code to reach production. Quality Control (QC) is reactive - it's about detecting and fixing defects after they occur. QC involves testing, inspecting, and validating the finished product to catch issues before they reach users. The key differences I see in practice: Timing: QA happens throughout the entire development lifecycle, while QC typically occurs at the end during testing phases. Focus: QA is process-oriented (how we build software), while QC is product-oriented (what we actually built). Approach: QA asks "Are we following the right processes?" while QC asks "Does this product work correctly?" Examples from my experience: QA activities: Writing coding standards, establishing review processes, creating test strategies, setting up CI/CD pipelines QC activities: Running test cases, performing code reviews, conducting user acceptance testing, bug reporting The relationship: QC is actually a subset of QA. You can't have effective quality control without solid quality assurance processes in place first. In practice, both are essential. Great QA processes reduce the number of defects QC needs to catch, but you still need QC as your safety net. Teams that only focus on one usually struggle with quality issues - either they're constantly firefighting bugs (weak QA) or they're shipping products with obvious defects (weak QC).
Dice control is assurance that the dice are legal and that the dice have not been tampered with or switched by a player.
Quality control focuses on identifying defects in products or services, while quality assurance focuses on preventing defects from occurring in the first place. Quality control involves inspecting and testing products, while quality assurance involves implementing processes and procedures to ensure consistent quality.
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.
tools used in audits and reviews to provide assurance on whether the subject matter of the engagement (such as internal control or management's discussion and analysis of operations) complies with applicable criteria for measurement and disclosure.
Section A of the annual statement of assurance typically outlines the governance framework and internal control systems within an organization. It provides an overview of the assessment process, including the roles and responsibilities of management in ensuring compliance with relevant laws and regulations. This section also highlights any identified risks and how they are being managed, as well as the overall effectiveness of the internal control mechanisms in place.
