Overview

Before seeing what needs to be done in the tool, an overview will explain the concepts.

At Project Definition level, we create a User Story (that is a Sequence Diagram), we will define the interactions between the Customer, the Product, the Environment and the internal activities of the system.

Interactions can generate internal activities, depending on <conditions>.

Internal activities can have performance Requirements (ex: timing performance).

At System Analysis level, we will analyze the internal activities and decompose the system into different functions. These functions can interact through INTER Functions flows.

We will reuse the interactions and their conditions from the previous level, and we will refine the Vehicle Performance Requirements with Functional Performance Requirements.
