FREE Product Quality Management Questions and Answers
Is carried out to test each individual part, usually a program, to make sure it is as error-free as possible.
A "Unit Test" is a type of software testing that focuses on testing individual components or units of a program in isolation to ensure that they are defect-free and functioning as intended. Unit testing is a fundamental practice in software development and quality assurance, and it is typically performed by developers themselves or by dedicated QA engineers.
A standard of quality control defined as one mistake for every million opportunities
"Six 9s of Quality" is indeed a measure of quality control that represents a very high level of reliability and precision. It refers to a product or process that has been engineered to have an extremely low failure rate. Each "9" represents one decimal place, and the number of nines indicates the level of reliability in terms of faults per million opportunities.
Anything that has to be altered before the program is delivered
A "Software Defect" (also known as a "bug" or "software issue") is any deviation from the expected behavior or functionality of a software program. It represents an unintended flaw, error, or problem in the code that needs to be addressed in order for the software to function as intended. A software defect can occur in any part of the software, including the code, design, user interface, or documentation.
Delivering goods that are appropriate for usage and meet requirements
Conformance is an integral part of quality management systems and practices. It helps organizations achieve consistent quality, reduce defects, and build customer trust. By focusing on conformance, organizations can enhance their reputation, reduce rework, and minimize the risk of delivering products that do not meet customer needs or expectations.
The initial investment for machinery used for inspection and preventative tasks
"Measurement and Test Equipment Costs" refer to the capital investment made by an organization to acquire the necessary tools, instruments, and equipment used for performing prevention and appraisal activities in quality management. These activities are aimed at ensuring that products, processes, and services meet the required quality standards and specifications.
The price of assessing procedures and results to make sure a project is error-free or has a manageable error range
"Appraisal Cost" is a term used in the context of quality management and cost accounting. It refers to the cost incurred by an organization to assess, measure, and evaluate processes and their outputs to ensure that products or services meet the required quality standards. The goal of incurring appraisal costs is to identify and address defects or errors before they reach the customer.
A charge for all mistakes that are not found and fixed before being delivered to the consumer.
"External Failure Cost" is a term used in quality management and cost accounting. It refers to the costs incurred by an organization due to defects, errors, or quality issues that are not detected and corrected before the product or service is delivered to the customer. These costs arise when defects or quality problems are identified after the product has reached the customer.
The price of organizing a project's planning and execution so that any errors are prevented or kept to a manageable level
Prevention costs involve expenses aimed at establishing processes, systems, and practices that minimize the occurrence of defects and errors. By addressing potential problems at their source, organizations can save costs associated with fixing issues later in the project lifecycle. The concept of prevention costs emphasizes the importance of a proactive approach to quality management.
Replaces trial and error tactics with scientific investigation in order to eliminate faults.
"Robust Design Methods" are an approach used in engineering and product development to design products and processes that are less sensitive to variations, uncertainties, and external factors, with the goal of reducing defects and improving overall quality. This approach emphasizes the use of scientific principles and systematic methodologies to minimize the impact of variability and improve the reliability and performance of products.
Demonstrates the number of units handled properly through the process steps.
Yield is a term used to represent the percentage of units that are successfully handled correctly through a process without defects or errors. It's often used as a measure of process efficiency and quality control. Yield is calculated by dividing the number of defect-free units produced by the total number of units that entered the process, and then multiplying by 100 to get the percentage.
Occurs in order to test the functioning of grouped components between unit and system testing.
"Integration Testing" is a phase of software testing that takes place between unit testing and system testing. It focuses on testing the interactions and interfaces between different units or components of a software system. The goal of integration testing is to ensure that these grouped components work together as intended and that any issues arising from their interactions are identified and resolved.
An expense required to fix a discovered flaw before the product is delivered to the consumer
"Internal Failure Cost" is a concept in quality management that refers to the costs incurred when defects or quality issues are identified and corrected within the organization's processes before the product reaches the customer. These costs are associated with identifying and addressing problems during production, preventing the defective product from being delivered to customers.
The price of conformance plus the price of non-conformance
"Cost of Quality" (COQ) is a comprehensive concept used in quality management and cost accounting to measure the total cost associated with achieving and maintaining quality within an organization. It encompasses both the costs incurred to ensure that products or services meet quality standards (cost of conformance) and the costs incurred due to failures or deviations from those standards (cost of non-conformance).
Accepting responsibility for mistakes or poor performance
Taking responsibility for failures and addressing non-conformance is essential to minimize the Cost of Non-Conformance. Organizations can reduce these costs by implementing robust quality management systems, conducting regular quality assessments, investing in employee training, fostering a culture of quality, and continuously improving processes. By focusing on preventing quality issues, organizations can not only save costs but also enhance customer satisfaction, loyalty, and long-term business success.
Test the system as a whole as a single unit.
"System Testing" is a phase of software testing that focuses on testing the entire software system as a complete entity to ensure that it meets its specified requirements and functions as intended. This phase comes after unit testing and integration testing and before the software is released for actual use. System testing involves evaluating the system's functionality, performance, security, and other aspects from an end-to-end perspective.
A three-step cycle that includes planning, monitoring, and recording the quality of an organization.
ISO 9000 is a set of international standards that outlines the principles and requirements for implementing a Quality Management System (QMS) within an organization. It focuses on ensuring that an organization consistently meets customer and regulatory requirements while aiming to enhance customer satisfaction and continuous improvement.
