In the handbook, Figure 2.0‐1 "SE in context of overall project management" shows the relationship between systems engineering and project management. While some SE responsibilities overlap with those of project management, the larger set of responsibilities focus on technical work. Microsoft Project isn't intended to be used to define requirements, perform technical trade studies, model and compare alternative system architectures, or configuration manage technical artifacts of the engineering process.
Hope that helps to clarify my prior comment. Happy to discuss more.

I never meant to imply that Microsoft Project is a suitable tool for aiding in any of these things. Anyone crazy enough to try...
But if you want to make a Gantt chart, Project does well enough. The NASA systems engineers I knew certainly used Project for that purpose. Thus I hardly think you can say that it "isn't suitable for systems engineering" as it is useful in creating/viewing/editing one of the key tools of a system engineer's work -- a project schedule.
