I was working with a client who wanted to produce a new line of products, but they were not meeting our established standards for quality control. After careful consideration and consultation with my team, we decided that it would be best to reject the product and refuse to accept it from the supplier.

This was a difficult decision because the client was expecting us to deliver on time and within budget. However, after weighing up all the risks associated with accepting a substandard product, we concluded that it was better to reject it than risk delivering an inferior product to our customers. We communicated our decision to the client and provided them with a detailed explanation of why we felt it was necessary to reject the product. In the end, the client respected our decision and accepted our reasoning.”

21. Are there any tools or technologies that you use when performing quality checks?
