Software Configuration Flashcards
What is software configuration?
Includes everything that can change during the lifetime of a piece of software
What are some examples of software configurations?
- Specifications (requirements, design, testing, etc)
- Source code etc
- Issues
- User Documentation
- Binaries
- Connecting/underlying services/software
- Libraries
- Compilers/Builders
- Hardware
What is software configuration management?
It is responsible for managing all the changes that can occurr
