If your team says it does MBSE but still treats Word documents as the truth, you probably don’t have a tool problem. You have a SysML skill gap, and it shows up in meetings long before it appears in testing.
Problems that remain hidden until integration or operations are usually more disruptive to correct than gaps found during requirements and architecture work. Each sign below points to a place where that risk can begin.

Models look full but don’t hold together
The first clues show up inside the model. There are plenty of diagrams to show, but not enough clarity to use.
1. One diagram type does all the work
Open the model and you see block definition diagrams everywhere. Every problem gets forced into a BDD, while activity, sequence, state machine, and parametric diagrams sit empty. Requirement diagrams hold a few old statements that no one updates. That pattern is syntax without method. The team can draw boxes but can’t select the view that answers the question at hand, so the model grows wide while staying shallow.
This often happens when teams learn tools before they learn modeling discipline. They don’t define who can change the structure or how a baseline gets set. SysML v2 includes textual notation and standardized API capabilities, making consistent model structure increasingly important as more work is shared between people and software.
2. Requirements can’t be traced through the model
Ask where a requirement is met and verified, and you get a pause. Someone opens a spreadsheet, while someone else opens a Word specification. The model contains requirements, but the trace links stop halfway, so you can’t move from need to test without hunting through other files.
Broken traceability quickly undermines confidence in a model. A capable team should be able to show the chain from stakeholder need through design and verification. If your team can’t do that, decisions fall back to memory. There’s no authoritative source of truth.
There are only files.
Reviews still run on slides and heroes
The next signs don’t appear in the model. They show up in how the team meets. If reviews ignore the model, it has no real authority.
3. Design reviews still run on static decks
The program claims to conduct model-based reviews, but the PDR still runs on PowerPoint. Diagrams get pasted as pictures. Numbers in the slides don’t match those in the model, and no one stops to ask which version is right. Legacy document-based habits are still winning over MBSE.
A model-centric review works differently. You walk through architecture and verification views live, then change a value and show the impact. Teams that can’t do that may not trust the model yet, and the weakness becomes visible when reviewers cannot query the underlying engineering information.
4. Integration surprises keep showing up late
Interfaces look fine until hardware meets software. Then a mismatch in units or timing stops testing for a week. The parametric diagrams that could have caught it sit blank because no one linked analysis to architecture. Teams may close that gap with structured sysml training that gives them a formal setting to practise the modelling habits needed to address interface problems earlier.
Static pictures don’t integrate. Executable models can reveal problems earlier. Once parameters and state machines connect to tools, faults can become visible before integration. That work takes discipline and is difficult to learn by watching videos alone.
Tools and people aren’t growing together
The last group concerns capacity. Licenses don’t create models. People do.
5. One person owns the model and no one else will touch it
Every team knows this person. They’re the only one who knows where things live in Cameo Systems Modeler or the team’s other MBSE tool. Reviews wait for them, updates wait for them, and vacations hurt.
That fiefdom feels safe until it isn’t. Senior modelers retire, and new hires arrive with no modeling exposure. Knowledge can leave with one resignation. Programs can stall when no one else can edit the structure safely.
6. Licensed tools sit half-used
The company pays for full seats. The team uses only the basic functions. Model governance stays off, with no version rules, baselines, or review workflow, so no one trusts what’s current. Tool vendors didn’t cause that. A lack of working habits did.
SysML v2’s API access and textual notation make disciplined structure especially important as teams connect models with more tools and automated workflows. Without training in configuration management and model review, teams risk carrying inconsistent practices into those workflows.
7. New hires have no path to get good
Ask how a junior becomes a capable modeler and you hear silence. There’s no course sequence, mentoring on real project data, or link to OCSMP certification for those who want proof of skill. Agile sprints keep moving. Confusion compounds.
Maturity frameworks offer a clear diagnosis here. A team at an early stage of adoption may be able to draw diagrams without yet modeling with rigor across a program. A defined path can address that gap. It starts with project-team reskilling on live work and grows toward enterprise-wide change once the habits stick.
What to do if you checked three or more
If you nodded at three or more signs, don’t buy more licenses. Your team needs a formal program with instructor-led labs and exercises relevant to its projects. Look for an approach that pairs OCSMP-aligned knowledge with hands-on use, allowing staff to apply new habits to live project work. Perfect models aren’t required at the start. Shared habits are, because they make the model the place where decisions happen.
