  SEMAT/OMG Essence provides a powerful Language and a Kernel for describing
software development processes. How can it be tweaked to apply it to systems
engineering methods description? We must harmonize Essence and various systems
engineering standards in order to provide a more formal system approach to
obtaining a Systems Engineering Essence. In this paper, an approach of using
Essence for systems engineering is presented. In this approach we partly
modified a Kernel only within engineering solution area of concerns and
completely preserved Language as an excellent situational method engineering
foundation.
