About this exam

The OMG-Certified Systems Modeling Language™ Professional (OCSMP) SysML® Model Builder Fundamental credential - commonly shortened to MBF - is the entry point of the OMG SysML certification series. OMG describes it as the prerequisite to the remaining SysML Model Builder exams, and the exams were designed by SysML and MBSE experts, many of whom co-authored the SysML specification, to meet industry demand for a more qualified MBSE workforce. The exam tests the knowledge and skills required to construct a basic SysML model of a system, covering model concepts and organization, purposes and benefits of modeling a system, basic requirements for capture and management, structure and behavior models, parametric models, allocation relationships, and use of stereotypes. MBF suits engineers who must build rather than merely read models: OMG positions a certified individual as a productive contributor, for example a reliability engineer or quality test engineer, in modeling tasks performed by a systems engineering team employing an MBSE approach using SysML. It is also the natural stepping stone toward the Model Builder Intermediate and Advanced exams. Preparation can combine OMG-Accredited Training, which is optional, with self-study using the official exam info sheet; you then book and pay through Pearson VUE. The exam costs $350 and is available in Japanese as well as English.

What you'll study

Common questions

About OCSMP Model Builder Fundamental preparation

What does the Model Builder Fundamental exam cover?

OMG lists eight topic areas: model concepts and organization, purposes and benefits of modeling a system, basic requirements capture and management, structure models, behavior models, parametric models, allocation relationships, and use of stereotypes. Expect questions that ask you to construct or complete a basic SysML model rather than only interpret one, since construction is the stated skill being tested.

How much does the exam cost, and how do I pay?

Each OMG exam is $350. You create or sign into a Pearson VUE account, through which you book, purchase, cancel, and reschedule exams and access receipts and score reports. OMG also publishes an Exam Discounts & Promos page and explains how to buy single and bulk exam vouchers, so check that page before paying full price.

What happens if I fail - can I retake it, and is it cheaper?

Yes. OMG states that if you fail your exam, you should check your score report for your 20% exam retake discount code. Retakes are booked through your Pearson VUE account like the original attempt. There is no published limit on attempts in the source material, but plan to address the weak domains shown on your report before rebooking.

Where and how do I take the test?

You schedule at a secure test center or online with online proctoring. OMG advises testing your system first if you choose the online option and contacting customer support for help. Booking, payment, cancellation, and rescheduling all happen through Pearson VUE. The exam is available in Japanese as well as in English.

How long does the exam take, and how many questions are there?

OMG's public pages do not state a question count or a time limit; those details sit in the downloadable exam info sheet linked from the exam tab. Download that sheet before you plan your pacing, and treat any question count or duration you see elsewhere as unverified unless it comes from OMG directly.

What score do I need to pass?

The passing score is not published on the OMG certification pages in the source material. Your Pearson VUE score report after the attempt is the authoritative record, and it is also where the retake discount code appears if you do not pass. Do not rely on second-hand passing percentages when deciding whether you are ready.

How should I prepare, and in what order should I take the SysML exams?

OMG allows either OMG-Accredited Training, which is optional, or self-preparation using the exam info sheets. MBF is the prerequisite to the remaining SysML Model Builder exams, so take it before Model Builder Intermediate, which in turn is the prerequisite to Model Builder Advanced. Model User is a separate interpretation-focused exam and is also a prerequisite to the remaining MB exams.

What do candidates most often get wrong on this exam?

The most common weakness is treating the exam as a diagram-symbol quiz. The stated skill is constructing a basic model, so practice building requirements, structure, behavior, parametric, and allocation elements in a tool and connecting them consistently. Also drill the stereotype and allocation material, which candidates tend to skim because it looks simple but appears throughout the domain list.

What do I receive after passing?

Within hours of passing, OMG issues Credly digital credentials that you claim and share; check your inbox and junk folder for the email. You can also print a PDF or hard copy of your certificate. The credential is OMG's industry stamp of approval of an individual's SysML modeling and analysis ability.

Is this the right certification if I only need to read models?

Probably not. If your job is interpreting models rather than building them, OMG's SysML Model User exam covers interpreting a basic model - system behavior, structure, requirements, and cross-cutting constructs - and targets a junior systems engineer. MBF targets productive contributors who construct models, such as reliability or quality test engineers.
