Yes, for a 2 mark question, write the definition and then an example.
HOWEVER, if there is a Case Study and the Question involves a Definition worth 2 Marks - Then you must definite the term, and then relate your definition to the Case Study Information provided.
I've done 8 Practice Exams for Business Management, and I haven't seen an Exam that asks for a Definition and has no Case Study Information provided before it. I don't think any of the VCAA exams do either. Usually, definition questions are used as a lead-in to get your brain thinking, and then the next question after that will be worth 3 or 4 Marks (or anything higher as well) which MAY or MAY NOT require you to refer to your Definition in an explanation for the Question.
95% of the time, there will be a Case Study, so you are expected to always relate back to it whenever you can, including for straight Definition Questions worth 2 Marks.
Hope this helps!
