System Testing

Correct answer: Six 9s of Quality

'Six 9s of Quality' (99.9999%) is a quality standard that aims for extremely high reliability, allowing for only 3.4 defects per million opportunities. This level of quality is often sought in critical systems where errors can have severe consequences, such as telecommunications or medical devices. It represents near-perfect performance.

Question 5: An expense required to fix a discovered flaw before the product is delivered to the consumer

External Failure Cost
Measurement and Test Equipment Costs
Internal Failure Cost (Correct answer)

Correct answer: Internal Failure Cost

Internal failure costs are expenses incurred to rectify defects or non-conformances discovered *before* the product is shipped to the customer. These include costs associated with rework, scrap, re-inspection, and retesting. They are distinct from external failure costs, which occur after the product has been delivered to the consumer.

Question 6: Is carried out to test each individual part, usually a program, to make sure it is as error-free as possible.

Unit Test (Correct answer)
User Acceptance Testing
System Testing

Correct answer: Unit Test

Unit testing involves testing individual components or 'units' of software in isolation to verify that each part functions correctly according to its design. This granular level of testing helps identify and fix bugs early in the development cycle, ensuring the building blocks of the system are robust and error-free before integration.

Question 7: Test the system as a whole as a single unit.

System Testing (Correct answer)
Unit Test
Integration Testing
User Acceptance Testing

Correct answer: System Testing

System testing evaluates the complete and integrated software system to ensure it meets specified requirements. It tests the entire system as a single entity, verifying that all components work together harmoniously and that the system performs as expected in its intended environment. This comprehensive test ensures the product functions as a whole.

Question 8: Anything that has to be altered before the program is delivered

Integration Testing
Software Defect (Correct answer)
Quality Circles

Correct answer: Software Defect

A software defect, often called a bug, is an error, flaw, or fault in a computer program that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. These defects must be identified and corrected before the program is delivered to ensure proper functionality and user satisfaction. Any necessary alteration before delivery points to a defect.

Question 9: Replaces trial and error tactics with scientific investigation in order to eliminate faults.

Robust Design Methods (Correct answer)

Correct answer: Robust Design Methods

Robust Design Methods, pioneered by Genichi Taguchi, focus on designing products and processes that are inherently insensitive to variations in manufacturing or environmental conditions. This approach uses scientific investigation and statistical methods to optimize designs, thereby reducing defects and improving quality without relying on costly trial-and-error. It proactively builds quality in, rather than inspecting it out.

Question 10: Occurs in order to test the functioning of grouped components between unit and system testing.

System Testing
User Acceptance Testing
Integration Testing (Correct answer)
Unit Test

Correct answer: Integration Testing

Integration testing is performed after unit testing and before system testing, focusing on verifying the interfaces and interactions between different modules or components of a software system. Its purpose is to ensure that these grouped components work together correctly as a cohesive unit, addressing issues that arise when individual units are combined. This bridges the gap between individual component functionality and overall system behavior.

Question 11: A three-step cycle that includes planning, monitoring, and recording the quality of an organization.

ISO 9000 (Correct answer)
Cost of Quality

Correct answer: ISO 9000

ISO 9000 is a globally recognized set of standards for quality management systems that guides organizations in establishing and maintaining effective quality processes. It outlines a systematic approach that includes planning for quality, continuously monitoring performance, and meticulously recording quality-related data. This cycle ensures that products and services consistently meet customer and regulatory requirements, fostering continuous improvement.

Question 12: The price of assessing procedures and results to make sure a project is error-free or has a manageable error range

Appraisal Cost (Correct answer)
Prevention Cost
Internal Failure Cost

Correct answer: Appraisal Cost

Appraisal costs are a component of the Cost of Quality, specifically related to evaluating products, processes, and services to ensure they conform to quality standards. These costs are incurred during activities like inspections, testing, and audits, all aimed at assessing quality and identifying defects. The goal is to catch errors before they reach the customer, ensuring a manageable error range.

Question 13: The initial investment for machinery used for inspection and preventative tasks

Appraisal Cost
Prevention Cost
Internal Failure Cost
Measurement and Test Equipment Costs (Correct answer)

Correct answer: Measurement and Test Equipment Costs

Measurement and Test Equipment Costs refer to the capital expenditure on tools and machinery specifically acquired for quality control activities. This includes the initial investment in equipment used for inspecting products, testing components, or performing preventative maintenance tasks. These tools are crucial for maintaining quality standards and ensuring compliance throughout a project's lifecycle.

Question 14: A charge for all mistakes that are not found and fixed before being delivered to the consumer.
