You are correct in your thinking. Quality control is an essential aspect of managing quality within a company. It involves checking and reviewing the work that has been done to ensure that it meets the desired quality standards. Without proper quality control measures, a company will face several challenges.

To understand how a company is doing without spending money on quality control, they would need to consider alternative methods. Here are a few possible approaches:

1. Customer Feedback: One way to gauge the quality of a company's products or services is by collecting and analyzing customer feedback. This can be done through surveys, online reviews, or direct communication with customers. By actively seeking feedback, a company can learn about the experiences and satisfaction levels of its customers, helping them understand how they are performing.

2. Internal Monitoring: Companies can also establish internal monitoring processes to track the quality of their work. This can include regular audits, inspections, or self-assessment checklists. By implementing such measures, the company can identify any potential quality issues and take corrective actions.

3. Quality Indicators: Developing quality indicators or key performance indicators (KPIs) can provide a quantitative measure of how well the company is performing. These indicators could include metrics such as customer complaints, product defects, or service errors. Tracking these indicators over time can reveal trends and help identify areas for improvement.

It is important to note that while these methods can provide some insight into the company's quality performance, they may not be as comprehensive or effective as a dedicated quality control system. Quality control involves a proactive and systematic approach to ensure consistent quality, and investing in it can help a company avoid costly quality issues, improve customer satisfaction, and ultimately enhance profitability.
