The Four Pillars of SysML (in 30 minutes)

This video presentation covers the basic concepts and notations of the Systems Modeling Language (SysML) in under an hour. I developed the original 4 pillars charts around 2006... since then they have been incorporated into a surprising variety of presentations, white papers, and textbooks. I recently decided to update the graphics and provide my own commentary in a more accessible format.

Very nice explanations, Thank you very much!

Nice pace man!. Other videos are basically just reciting the official docs where they mention every type of connection etc. At least here you give a good overview of what most people will want to use.

Setting Systems Engineering back more than 50 years.

As a Systems Engineer practicing for 36 years I am dumbfounded. Apparently Object Oriented S/W programming needs have now driven a redesign of Systems Engineering practices so that the coders' job can be done without the need to think.

If SysML turns out anything like Object Oriented Code, the documentation generated will be nearly indecipherable and scattered willy nilly so that putting it into an understandable description of what the system does will take longer than the design required in the first place.

I do appreciate the explanation however, it is well presented. I just fail to see the utility in SysML other than placating the needs of OO programmers. It certainly doesn't do much to help understand what a system is actually supposed to be doing as far as I can see.
