12. What is Software? What is Software? More than computer programs
Computer programs, procedures, and possibly associated documentation and data pertaining to the operation of a computer system.
Two major types of Software:
Generic –Stand alone, sold on open market
Customized –For specific customer

13. What is Software Quality?
Software Quality (as per ISO/ IEC 9126):
The totality of functionality and features of a software product that contribute to its ability to satisfy stated or implied needs.
Software Quality (as IEEE Std 610):
The degree to which a component, system or process meets specified requirements and/or user/customer needs and expectations.

14. What is Software Quality?
According to ISO 9126, software quality consists of:
Functionality
Reliability
Usability
Efficiency
Maintainability
Portability

15. Introduction What’s the main challenges of software development
now-a-days?
High Cost
Difficult to deliver on Time
Low Quality

16. Introduction What is Software Quality Assurance?
What is Software Testing?
What are the differences between them?

17. Introduction Software Quality Assurance (SQA):
Defined as a planned and systematic approach to the evaluation of the quality of and adherence to software product standards, processes, and procedures.
An umbrella activity that is applied throughout the software process.
Consists of a means of monitoring the software engineering processes and methods used to ensure quality.
An effective approach to produce high quality software.

18. Introduction Software Testing:
Software Testing is the process of executing a system or component under specified conditions with the intent of finding defects/bugs and to verify that it satisfies specified requirements.
Main goal ==> To detect bugs
Have different levels
Static testing vs. Dynamic testing
Manual testing vs. Automated testing

19. QA vs. Testing Software Testing Software Quality Assurance
Process-oriented activity
Oriented to bug prevention
Product-oriented activity
Oriented to bug detection

20. Introduction
What is the COST of a bug?

21. Introduction Failure Example 01 Flight Ariane 5
(Most Expensive Computer Bug in History)
On June 4, 1996, the rocket Ariane 5 tore itself apart 37 seconds after launch because of a malfunction in the control software making the fault most expensive computer bug in history.
==> mission critical issue

22. Introduction Failure Example 02 Lethal X-Rays :Therac-25 system
Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in But initially lot of people died because of massive overdose of radiation. And this is happen because of a software bug.
==> safety critical issue
