The focus is on trialling the components and components (parts) of the outcome.
For example you might trial:
- The CSS for a website
- Navigation for a website
- Functions for a program
- Queries fora database
- Functions for a Spreadsheet model
- Subsystems in an electronic circuit
- Systems or parts in a computer system
- Systems or parts in a network development
As a result you can determine the most suitable outcome.
