Model‐Based Systems Engineering (MBSE) is emerging as a pivotal paradigm, placing modeling as the underlying activity of systems' and products' lifecycle management. SysML is the OMG standard for MBSE, while Object‐Process Methodology (OPM), one of the six leading INCOSE MBSE methodologies, is in the process of becoming ISO standard and the basis for model‐based standards authoring. OPM and SysML complement each other, as each is especially suited for different lifecycle stages: OPM, which is simple and holistic, is most fit for the early conceptual stages, whereas SysML, which provides for expressing details, is good for later design stages. The tutorial introduces the principles, syntax, and semantics of OPM and SysML, highlighting their commonalities and differences, and showing how to use both in ways that promote synergy and improve critical system features, notably clarity, consistency, and completeness. The resulting model is an indispensible blueprint that puts all the stakeholders on the same page across the system lifecycle span.
