Primary action sequence
A primary action sequence is the normal ordered set of interactions between an actor and an application during a use case.
Object-Oriented Software Design in C++
The expected ordered set of interactions that occurs during a use case.
- How it is used
- Structures detailed use case behavior after a triggering actor starts an interaction.
- How deep it goes
- Defines ordered interactions, limits them to about 10 steps, and defers failures to alternate action sequences.
- Examples
- Uses a customer searching a book catalogue through an attribute form and receiving matching books.
- What you can do after
- Evaluate whether a use case is practical and split it when its action sequence becomes too complex.

Software Design for Python Programmers
A primary action sequence is the normal ordered set of interactions between an actor and an application during a use case.
- How it is used
- Structures the normal interaction flow within a use case description.
- How deep it goes
- Defines ordered actor-facing steps and limits them to about ten, while deferring failures to alternate sequences.
- Examples
- Uses a customer searching a book catalogue through an online form as its concrete interaction example.
- What you can do after
- Apply it via use case descriptions to document practical normal interactions from an actor’s perspective.
