  2. Outline • Terminology • How does V&V fit in the lifecycle? • Waterfall lifecycle • Testing Relationships

  3. Terminology from IEEE Glossary (1) • bug: See fault • defect: See fault. • fault: A manifestation of an error in software. A fault, if encountered, may cause a failure. • failure: The inability of a system to perform a required function within specified limits. A failure may be produced when a fault is encountered • error: Human action that results in software containing a fault

  4. Terminology from IEEE Glossary (2) • static analysis: The process of evaluating software without executing it. • dynamic analysis: The process of evaluating software based on its execution.

  5. Terminology from IEEE Glossary (3) • verification: The process of determining whether or not the products of a given phase... fulfill the requirements...Did we build it right? • validation: The process of evaluating software... to ensure compliance with software requirements.Did we build the right thing?
