Concepts & Terminologies
• What is Quality?
– Conformances to requirements
– Fitness for use
– performs these specified functions correctly over repeated use or over a long period of time

Concepts & Terminologies
• Purpose of QA
– To ensure software quality through the related set of (validation and verification) activities

Concepts & Terminologies
Error, Fault, Failure and Defect
![Page 14: Quality Assurance in SDLC](https://reader034.fdocuments.us/reader034/viewer/2022050920/5489823db4795984178b556e/html5/thumbnails/14.jpg)
Concepts & Terminologies
Error
• Missing/Incorrect Human action
Fault
• Incorrect step in computer program
Failure
• Inability of a system
• Behavioral deviation
Collectively referred as Defect

Concepts & Terminologies
Verification and Validation?
![Page 16: Quality Assurance in SDLC](https://reader034.fdocuments.us/reader034/viewer/2022050920/5489823db4795984178b556e/html5/thumbnails/16.jpg)
Concepts & Terminologies
Verification
• Verification evaluates documents, plans, code, requirements, and specifications
• For example,
• Inconsistent Requirements
• Design Walkthroughs
• Code Inspections
Validation
• Validation evaluates the product itself.
• Involves the execution of tests designed to cover each of the specific system requirements

Practices
• So how it is done in Industry?
• Create a QA plan/test strategy Planning
• Specification Review Analysis
Design
• Develop test cases for testing (validation) Development
• Test cases execution on developed software and Integration testing Testing
• Build validation/Shipment assurance Deployment
![Page 19: Quality Assurance in SDLC](https://reader034.fdocuments.us/reader034/viewer/2022050920/5489823db4795984178b556e/html5/thumbnails/19.jpg)
Practices
• It could be improved like
• Create a QA plan/test strategy
• Review project plan Planning
• Specification Review Analysis
• Analyze design Design
• Develop test cases for testing (validation)
• Code Inspection/Review
• Unit Testing
Development
• Test cases execution on developed software
• Integration testing
• Test Automation (tools)
• Non-Functional Testing
Testing
• Build validation/Shipment assurance Deployment
