Which of the following is an advantage of quality assurance?

Choosing the option that states "Everyone becomes responsible for quality" highlights an essential principle of quality assurance in business processes. This approach emphasizes that every employee, irrespective of their role, plays a vital part in maintaining and enhancing the quality standards of products or services.

When the entire workforce is engaged in quality assurance, it fosters a culture of accountability and ownership. Employees become more invested in the outcomes of their work, leading to collective efforts towards minimizing errors and improving processes. This not only enhances the overall quality of output but also promotes teamwork and communication across departments, ultimately leading to more efficient operations.

In contrast, the other options imply aspects that negatively affect operations and employee engagement. For instance, increased need for final inspection suggests a reactive approach to quality, where mistakes are identified at the end of the process rather than prevented throughout. Higher production costs relate to the financial burdens associated with poor quality management rather than the benefits of effective systems. Lastly, less employee motivation can stem from a lack of ownership or recognition in the quality assurance process, which is contrary to the goals of instilling a quality culture. Thus, the correct answer captures the positive influence of a comprehensive quality assurance system on employee involvement and responsibility.
