QS 9000:
A quality certification program used in the automotive industry which is based on the ISO 9000 standards.
Qualifier:
A data element, which identifies or defines a related element, set of elements or a segment. The qualifier contains a code from a list of approved codes.
Qualitative Forecasting Techniques:
A forecasting method where intuition or judgment is typically required due to the lack of hard quantitative facts. An example is where a new product is being introduced.
Quality:
The degree to which a set of defined characteristics of a product or service fulfills known requirements. The common element of the business definitions is that the quality of a product or service refers to the perception of the degree to which the product or service meets the customer's expectations. Quality has no specific meaning unless related to a specific function and/or object. Quality is a perceptual, conditional and somewhat subjective attribute.
Quality Circle:
A group composed of of individuals trained trained to identify, analyze and solve work-related problems. They present their solutions to management in order to improve the performance of the organization, and motivate and enrich the work of employees. When matured, true quality circles become self-managing, having gained the confidence of management. Typical topics are improving occupational safety and health, improving product design, and improvement in the workplace and manufacturing processes. Also see: Small Group Improvement Activity
Quality Control (QC):
The management function that ensures that the goods or services manufactured or purchased meet the product or service specifications
Quality Function Deployment (QFD):
A structured method for translating user requirements into detailed design specifications using a continual stream of ‘what-how’ matrices. QFD links the needs of the customer (end user) with design, development, engineering, manufacturing, and service functions. It helps organizations seek out both spoken and unspoken needs, translate these into actions and designs, and focus various business functions toward achieving this common goal.
Quality Policy:
A statement of the overall quality intentions and direction of an organization as formally expressed by top management. A quality policy is a compliance requirement for ISO 9001.
Quantitative Forecasting Techniques:
A forecasting method that relies on expert human judgment combined with a rating scale, instead of being purely based on hard (measurable and verifiable) data. Also see: Extrinsic Forecasting Method, Intrinsic Forecasting Method
Quantity Based Order System:
See: Fixed Reorder Quantity Inventory Model
Quarantine:
The act of setting aside materials which do not appear to meet known quality standards. Typically items in quarantine are placed into a secured area to prevent their use while an investigation is conducted and disposition is determined.
Quick Response (QR):
A strategy widely adopted by general merchandise and soft lines retailers and manufacturers to reduce retail out-of-stocks, forced markdowns and operating expenses. These goals are accomplished through shipping accuracy and reduced response time. QR is a partnership strategy in which suppliers and retailers work together to respond more rapidly to the consumer by sharing point-of-sale scan data, enabling both to forecast replenishment needs.
