  Despite potential benefits in Software Engineering (SE), adoption of software
modelling in industry is low. Technical issues such as tool support have gained
significant research before, but individual guidance and training have received
little attention. As a first step towards providing the necessary guidance in
modelling, we conduct a systematic literature review (SLR) to explore the
current state of the art. We searched academic literature for modelling
guidance, and selected 25 papers for full-text screening through three rounds
of selection. We find research on modelling guidance to be fragmented, with
inconsistent usage of terminology, and a lack of empirical validation or
supporting evidence. We outline the different dimensions commonly used to
provide guidance on software modelling. Additionally, we provide definitions of
the three terms modelling method, style, and guideline as current literature
lacks a well-defined distinction between them. These definitions can help
distinguishing between important concepts and provide precise modelling
guidance.
