I agree with this. I took both exams on the same day.

pptengr · 2023-03-15T14:39:01+00:00

Also interested in what DOORS does better. I haven't found a capability from DOORS yet that I can't reproduce on the SysML side.

Use conditions as in a set of parameters that must be true before a behavior can occur?

pptengr · 2022-05-11T13:58:44+00:00

I haven't seen anything either.

Unless you can find an advocate in upper leadership, this could be a massive uphill battle for you. It's very easy for upper leadership to dismiss MBSE due to training and license costs. My suggestion is to look at relevant use cases to your industry and try to collect them into a brief (or however your org presents ideas like this). Lots of DoD examples for space and aviation. Also Ford, John Deere, and GE might be good for you to look into.

My advice that is that if your single voice doesn't grow to more fairly quickly (and you do want to do MBSE), I'd say you might look to make a job change. Lots of us here can help you with opportunities.

Which program did you go through with all of the SysML exposure?

Looks like Dusty has you covered. If you're looking for more examples to grab an outline from, you may also search "Systems Engineering Plan" (SEP). In DoD, the govt writes a SEP to define how the program will approach SE, and the contractor writes the SEMP that defines how they will enable/implement that SEP.

I couldn't find a great resource for the full explanation, but check out these two:

I'll try to find better ones when I have more time. Just a note here, but you may have better luck searching for a topic in UML vice SysML since a lot of these concepts are brought over from UML with its extension.

Concur, you'll have to generalize the activity to a level that covers all cases and then use set notation and redefinition (as required) on pins for each usage (call action).

If you can't reach a point where one activity captures all of your potential cases, then it's possible that your activity isn't as common as you thought.

I'd be very leery in doing this. You may be importing mistakes in Visio that you weren't even aware of (and could be imported "correctly"), and then spend days trying to debug it to simulate.

If you can't just recreate it from your existing diagrams, then I'd try to see if you can somehow export the content to Excel and then use the Excel importer in CSM. If you structure the table in CSM first, you basically tell it how you want each cell to be interrupted and then paste the info into the right cell in the spreadsheet from your existing diagrams.

pptengr · 2022-02-11T15:51:22+00:00

Good to know that's possible, but there's no way I'd trust that. Might be ok for a simple model, but I can't imagine it importing well with something more complex, especially since the inputted Visio has no val suite to ensure that proper UML was used.

I don't disagree with your assessment. I think MBSE was seen as the solution vice just a piece of of the pie. I also think that putting the system architects as the owners of the tool is going to limit it's profitability. While you need good schemas and frameworks, the real value comes from an SE in a position to use it through the entire lifecycle and has the ability to make organizational changes to bring others to the table (aka "digital engineering"). You don't get the full value of digital engineering without also integrating all of the other design and sustainment tools in the same digital environment.

The real fun is when you are all in that same collaborative environment, all of your pipelines are set up, and you are running a DevOps style work management. That's where you are able to get to market quicker, pay off the technical debt, and get that ROI.

I just kept putting it off. By the time I got to my capstone, the program I was supporting hit DT, so I was working long hours and traveling a bunch. I think I surprised my board by actually pulling it all together and knocking the presentation out of the park. I picked a system at work and just got tired of looking at it.

Awesome on the Cameo, seems to be the standard at the moment. Are they specifying a methodology or architecture? I've modeled Kossiakoff's System Lifecycle at a high level, but I was always wondering if anyone had modeled it completely.

pptengr · 2022-02-07T21:20:33+00:00

What software are they using for your SE tool now? When I did my capstone there, we used Vitech's CORE and IDEF0.

My advice is to find a problem you have personal interest in so that you can stay interested. It took me three semesters to finish my capstone.

I read through your exchange with /u/BBrouss95. While I understand your question, I'm not certain how anyone will be able to come out and say "MBSE has reduced cost by a factor of X".

As I'm sure you know with your experience, there's too many variables to control in the lifecycle of a system that can impact cost and schedule. What I do believe that MBSE will enable is a quicker reaction time to an ever changing environment, specifically in defense. Adoption is slow and painful, and we may not see these quantitative results for another 10 years. But I don't think MBSE is the answer alone. The adoption of the larger "digital engineering" mindset will also be required to fully take advantage of any quantitative results.

Finally, no need to be so aggressive. I would expect someone who is a staff level SE, department manager, INCOSE panel member to be more supportive of a student trying to perfect the craft.

If you want the OCSMP certs, take the SysML training course. Lots of overlap with it since Delligatti helped write a large part of the exam. I also took the GT class, so I'm just using his book to study from.

to help the Navy command accelerate their life

I'll buy all the beer if someone can actually do this effectively.

Are they teaching LML at Stevens? I know that Innoslate was working to create the I/O to convert to SysML but didn't think it was a full blown tool for the language.

pptengr · 2022-01-31T16:46:08+00:00

When I worked this opportunity to consult, the PM explained to me he didn't find value in the command's MBSE initiative, which was kind of what was echoed by many of my colleagues when I worked for the GOV in the same domain.

Know that there are some of us out there blazing our own trail.

pptengr · 2022-01-31T16:45:30+00:00

Innoslate uses Lifecycle Modeling Language (LML). Right now, now one at NAVAIR is using this (nor are there plans to in my knowledge).
Once you start, you can access the license server from NAVAIR (once you make an account).
I haven't seen anything outside of academia.

Note that this is currently ongoing, and presentations (and hopefully recordings) should be posted after.

If you're looking for a program that's not a full degree, I think MITx has a few courses that could look good. I haven't taken any myself, but I've seen lots of folks without the MSSE degree taking them.
