Webel Parsing Analysis (with strict traceability of all elicited model elements) can be used side-by-side with "freestyle" modelling with incremental benefit the more it is used.
Even relatively informal elicitation of model elements using the SysML ElementGroup and a Parsing Analysis approach is extremely powerful.
Translating authoritative technical documents written in “natural” engineering language (snippet-by-snippet) into Webel Parsing Analysis diagrams creates consistent underlying systems models and can bridge easily to existing methodologies.
Humans work well with natural language: Many stakeholders – including those who are not necessarily familiar with UML or SysML modelling symbols and diagrams - benefit enormously from having plain text in diagrams side-by-side with graphics.
Webel Parsing Analysis is a "meta-process" that can be applied to general domain source documents to elicit Requirements (and related model elements) or to a Requirements Specification itself as a special case of a domain source document!
Not even the most experienced requirements engineers can easily state requirements perfectly in consistent requirements-friendly language first shot; requirements and constraints are often buried in the natural text of domain source documents.

Webel Parsing Analysis: A Snippet (keyword «snippet») must have exactly one 'source' Document (keyword «document»).
Webel Parsing Analysis: A custom Document stereotype (keyword «document») extends the UML standard profile Document that extends Artifact (which is NOT in the UML4SysML intersection). Such a Document may act as the 'source' of a «snippet».
