A company believes that their manufacturing processes can be measured, analyzed, improved, and controlled. They have the commitment of the entire organization, particularly top management, to initiate a quality control process. The company has decided to produce output of their product at or below a particular defect level with the goal of improving all of their processes to that level of quality or better. Which quality process is the company using

Customer relationship management (CRM) is primarily concerned with managing a company's interactions and relationships with current and potential customers. While important for overall business strategy, CRM does not directly address manufacturing processes or defect levels, making it irrelevant to the company's goals for quality control.

Reengineering involves radically redesigning business processes to achieve significant improvements in productivity, cycle times, and quality. Although it may lead to quality improvements, it is not specifically focused on defect reduction at a defined level like Six Sigma is. Therefore, while it could be part of a broader strategy, it does not align with the company’s specific commitment to defect levels.

ISO 9000 refers to a set of international standards for quality management systems. While it emphasizes quality assurance and continuous improvement, it does not provide a structured methodology to achieve specific defect levels or process improvements like Six Sigma. Thus, it does not fully encapsulate the proactive approach described by the company.
