System Requirements Engineering

5Integration with Other Methods

5.1. Context

In this chapter, we analyze how our method can be integrated with other approaches. This makes it possible to highlight similarities and, particularly, the elements that are complementary.

First, we will conduct this analysis using the IBM Harmony SE method supported by the Rhapsody tool, which is the method used in the ISC Master. Then, we will discuss the Arcadia and Cesam methods widely used by companies that regularly host ISC Master’s students on internships.

5.2. Integration with the Harmony SE method

The Harmony SE [HAR 14] method is integrated into the Rhapsody software tool via a specific profile that must be added to a SysML project. The approach is as follows:

• – add the Harmony SE method to the project from the “File” menu on “Add Profile To Model” by choosing the HarmonySE directory and then the HarmonySE.sbs file before validating;
• – create the Harmony SE project by right-clicking on the project in the tree structure, then on “SE-Toolkit” and “Create Harmony Project”.

5.2.1. Modification of the project structure

Creating the Harmony SE project allows us to create an organized project structure with five main packages (SysML Package) as shown on the left part of Figure 5.1. In particular, this structure highlights the main engineering processes with physical architecture (Design Synthesis), functional architecture (Functional Analysis) and requirements analysis (Requirements Analysis).
