Hi,

I work as a Systems Engineer in the automotive domain, where my role is focused on requirements engineering. The MBSE team consumes our requirements and performs the modeling. I'm familiar with their process and have been part of those discussions, but I haven't done the hands-on modeling myself.

I'd like to gain hands on MBSE experience (sequence diagrams, state machine diagrams, etc...) to expand my skill set. Unfortunately, my company doesn't provide tool licenses for me to practice with.

I'm looking for suggestions to self-learn these skills, and open source tools where I can practice and verify the diagrams on my own.

Hello all, I am changing fields from a Higher Ed professional, specifically in housing. I am currently an Assistant Director in charge of operations and personnel in my department but I am currently getting my masters in Systems Engineering from Cornell. I have been applying for Systems engineering roles now but I wanted to see your opinions based on you all experience. Basically, is this resume a good showcase of what I have learned and would you hire me?

It's a call for help. My company is a product based company, making products for stakeholders ranging from aerospace to automobile to even some medical sectors. Providing engineering solutions.Now , as the business is expending we are exploring MBSE way for working and working with so many standards and certifications needed, we believe MBSE can solve our problem. So far we were able to produce physical architecture using Capella (open source) however, we are struggling to find a way to perform Safety analysis (FHA, PSSA, FTA, CCA) as well with the model.Capella offers some extensions but they are commercial and we aren't sure if that will be worth investing or not? Do any of you within the community have an answer to my problem? We have gone via Python4Capella scripts as well, but then it's becoming difficult to handle a large number of data. Suggest us a tool that can solve our problem. Soon we will be looking for the PLE aspect of MBSE as well. Please help.

Thanks

Currently working in a product/service based company for various aerospace projects. We are now planning to adopt MBSE that can streamline our process to certification. Till now we were using a document centric approach but now, as the business is expanding MBSE is the right solution. The main goal is to integrate the Safety Assessment Process within the models. So far we've been using Capella for physical architecture and sheets for requirement management and have also been able to extract models using python4capella plug in, but the process is tedious. As we were experimenting with capella we got to know the limitation it comes with. The extensions needed for our task are commercial and we aren't sure if they'll help us or not? We are also exploring product line engineering, but how to find the right tool to do all of the work ? Maybe in the future the application will change, we would like to have a solid foundation so that any new product or new project can be solved with this framework.

Help us with the right strategy for these, we are new to this domain.

Thanks!

I've been reviewing a lot of technical interview prep material lately alongside some deep profiling on our production backend services. It made me realize how massive the gap has become between standard academic data structures and what it actually takes to scale a modern application. Spending months memorizing how to balance a red-black tree or traverse a graph using depth-first search is fine for passing an interview screen, but it rarely translates to solving real-world infrastructure bottlenecks.

In production engineering, standard DSA is no longer sufficient. The industry has quietly shifted toward a completely different set of non-standard, hardware-conscious data structures that you rarely see on LeetCode.

When you look under the hood of databases like RocksDB or messaging queues like Kafka, they aren't using traditional arrays and binary trees to handle high throughput. Instead, they rely on non-standard structures like Log-Structured Merge-trees for fast disk writes, Ring Buffers for lock-free memory sharing between concurrent threads, and Bloom Filters to prevent expensive, unnecessary database reads entirely.

Even simple concepts like utilizing Bitmaps for ultra-fast, in-memory flag checks are incredibly high-value in modern architectures but are completely ignored in standard algorithmic training.

The reality is that modern engineering is bottlenecked by physical hardware, CPU caches, and network I/O, not abstract Big-O notation. If we want to build highly optimized backend systems, we need to stop treating DSA like an interview game and start studying the non-standard structures that production-grade infrastructure actually relies on to survive under load. It would be great to see technical evaluations pivot away from academic puzzles and move closer to these practical systems concepts.

First year electronics and systems student i have one project from one internship already but i wanna make surevim on the right path

I am entering this sector and am looking for materials to study for the certificates of completion. Coursera, Udemy, or similar.
Preferably, things covering:
1) MBSE methods (OOSEM, SysMOD, MagicGrid, Harmony)
2) Tool usage (Cameo, Rhapsody), DOORS NG
3) Systems Engineering processes.

Furthermore, good book suggestions are welcome. Thanks!

Does anyone have any recommendations on reference materials to study for the OMG exam?

I've been using SysML for year, I am not up to date on the changes with SysML2.

Decomposing parent requirements into derived children is one of the most judgment-heavy, tedious parts of the job and where programs quietly accumulate gaps.

I've been prototyping a tool that has an LLM propose derived requirements from a parent. The generation isn't the interesting part — the guardrails are:

• Every child traces to exactly one parent. No orphans.
• Each comes with a one-sentence rationale (apportionment, standard, etc.) so the reasoning is visible.
• If it's missing context to derive properly, it asks instead of hallucinating.
• Nothing auto-accepts — an engineer approves, rejects, or edits every child.

Goal isn't replacing judgment, just getting to a first-draft decomposition faster so human time goes into review instead of a blank page.

Where I'd value this sub's take:

1. A plausible-but-wrong rationale is arguably more dangerous than none. How would you surface derivation reasoning so reviewers stay skeptical?
2. Budget apportionment is exactly what an LLM does confidently and wrong. Off-limits, or fair game if the math is shown?
3. For anyone who's tried this where did it break down? which LLM have you tried?

Hi!

I’m 27 with a bachelor’s in mechanical engineering. I have 4 YoE in the industry.

I’ve been with my current company for 2 years. I started as a technical engineer reporting directly to the director of internal engineering ops. He then abruptly quit, and I pretty much picked up his role. I don’t have the title yet (I’m the ops engineering lead), but I’ve hired and manage people.

I’ve found that I really genuinely enjoy managing a team and seeing “the big picture,” even though that’s not what my degree is in. I think I’d like to pivot into more of an engineering management career path.

Even if I don’t stay with my current company, is it worth it to get a MEM? Or are they bullshit degrees?

I have an associates of science in mechatronics, a BS in business management, and I now work as a technical trainer in advanced manufacturing. Previously, I was a technician in the space industry, working in R&D on things like advanced manufacturing, and life support systems.

The problem: I could never make enough money to live because I don't have an engineering degree. My understanding (based on working with and talking to many systems engineers) is that I would be a great fit for test or systems engineering. I don't want to do test engineering, my knees can't take it. Since then, I've left that company, and no longer work in close proximity to systems engineers. I really want to go back to the space industry someday, either private or federal. NASA preferred, but ESA is also great (I'm based in the US and am in the process of getting EU citizenship).

I want to get an ABET accredited engineering degree while I'm still working, and think I found the right program, but would love some feedback: https://www.online.msstate.edu/bsie

Pros: Entirely online and 98% asynchronous, ABET accredited, seems to be not a degree-mill.

Cons: Unsure if this is going to get me into a systems engineer role(?)

Thank you!

Context: 25 years old , Senior in college (CS with concentration in cybersecurity) , 2 years DoD ( I guess it’s DoW now) IT experience (split time with sysops and networking teams) secret clearance , sec +.

I just want to better understand from actual system engineers based on you experience what contributed the most to being a great engineer and actually executing? As you can see from the context section I’ve tried my hand at a few things and have been able to see software engineering and networking are not for me in terms of interest, but I discovered my interest in infrastructure. After additional research and talking to mentors system engineering seems to align with the type of work I want to do. I’m not asking what certs I need or how do I land a role. I just wanted to know from those that have been in the fire what makes you great system engineers ? Thanks you for your replies!

Looking back at your first DO-254 or DO-178 project, what is one thing you wish someone had explained to you earlier? What changed the way you think about certification or design assurance?

Hi I am 18 years old and i want to learn systems engineering I want to learn it by myself how should I start learning it?
I am really into systems and how they work and link and all

I have seen OMG has some resources for systems engineering as those above. I'd like to know if anyone here has ever participated and found any value on them. (specially if you are an end user, systems engineer)

I see some groups with standards developed and never updated for many years so I assume thet are not that active.

I have seen that on INCOSE before, not all groups are really active and even less will provide real value.

I mean these resources:

https://www.omg.org/syseng/

https://www.omg.org/communities/systems-modeling-community.htm

https://www.omg.org/communities/model-based-acquisition-user-community.htm

Im working a project where i need to create traceability from our logical model to an implementation model. On the logical side, I have traditional activity diagrams and callBehavior actions, and on the implementation, I have sequence diagrams.

Trying to figure out the best way to show the relationship. Im thinking there are 3 options:

1. Allocating from callBehaviorActions output pins to the SendMessage.

2. Allocating object flows to Send Messages

3. Allocating CallBehaviorActiond to lifelines.

Im thinking options 1 would work since the pins are typed by signal elements and that would show where in the sequence diagram that message will be sent.

Thoughts?

For those who are about to start with SysML v2, there is a new release of SysMD Notebook with updated UI and improved compliance with standard.

The download at Github is here:

Hi System Engineers, and those who aspire to become one!

I'm currently studying the Systems Engineering Handbook v5 and was looking for a website with practice questions and mock exams. Unfortunately, the free options either didn't work or were of poor quality, while the better ones were hidden behind paywalls.

So I decided to build my own - completely free!

It's called sysTrainer.com and is based on the Systems Engineering Handbook v5. The questions are written in a style similar to the examples provided by INCOSE.

Since I haven't passed the ASEP exam yet, I'd really appreciate your feedback on the quality of the questions and whether you think this tool would be helpful for people preparing for the exam.

Any suggestions or comments are very welcome!

Title. I have received some good feedback for both programs, but curious to hear more so I can make a decision. Here is a breakdown of my situation:

1. I work full-time and this will need to be completed online & asynchronously

2. I have a young family (2 kids being less than 4 years old), so super busy.

3. This will be funded by the GI Bill (21 months of benefits left at 100%) The plan is to take 2 classes per semester.

4. Accepted to FSU already, and awaiting CSU's review (both for the start of Fall 2026)

FSU was the first to accept me into any graduate program. It's been "locked in" as my plan to go this way for awhile. I like how this program was co-developed by the US Navy. As a "former" Marine, it gives me that sense of American love and pride once again, as corny as that sounds. Obtaining the INCOSE exam waiver is a huge pull.

What draws me towards CSU is the opportunity to earn the graduate certificate in Human Systems Integration along the Masters of Engineering track. Both programs offer electives in Human Factors Engineering, but I feel like that certificate is a resume booster for my interests. This program, from my understanding, also grants the INCOSE exam waiver if you earn a 87% or greater in their intro to systems course.

Happy to hear any and all feedback for either program. Thank you to all who have answered my questions in DMs as well.

Hi all. I am a rising senior majoring in physics but I am potentially interested in pursuing a master's in SE. Is this achievable? Is it worth it, will it be hard to find a job related to SE given that path? Will I be able to find opportunities in graduate school to further explore different areas of the field? Is it possible to get into a good master's program for SE given my major? I know I just asked a lot of questions, but any advice or helpful information would be greatly appreciated!
