Ce que l'on conçoit bien s'énonce clairement ... (N.Boileau)

This is the first chapter:

Requirements Analysis

The aim of the "Requirements Analysis" is to get a complete description of our system environment, focusing on the user needs. The objective is thus to identify the external actors, the data flows between the actors and the system and finally the list of Use Cases.

Actors:

The analyst team, specialised in collecting and formalising the user requirements.

The key question here is:
=> "What is the system ?"

Inputs:
=> User Requirements (needs)

Outputs:
=> UML Model
=> MMI prototype (if needed)
=> Requirements Analysis Document
=> Validation Plan Document

Activities:
=> Activity A : Definition of Actors
=> Activity B : Definition of Context
=> Activity C : System Description
