OCSMP Model User case studies
OCSMP Model User · Put your knowledge to work in context.
The OMG-Certified Systems Modeling Language Professional (OCSMP) Model User credential - abbreviated MU - is the entry-level exam in the OMG SysML certification series. According to OMG, the exam tests the knowledge and skills required to interpret a basic SysML model of a system, covering system behavior, structure, and requirements as well as cross-cutting constructs. OMG positions the Model User as the prerequisite to the remaining SysML Model Builder exams (Model Builder Fundamental, Intermediate, and Advanced), and describes the certified individual as a productive contributor - for example a junior systems engineer - who interprets models within a systems engineering team using a model-based systems engineering approach with SysML. The exam is delivered through Pearson VUE, either at a secure test center or online, and OMG notes that it is available in Japanese. The OCSMP Model User case studies are 5 cases and about 3,330 words.
