Start with a DEFINITION. Even if the answer doest have something obvious to define, draw on the case study and relate it to the question to find a defintion. A good definition could get you up to 2 content marks.
Next, if it is an analysis question (like "in your opinion" or "discuss"

make the ARGUMENT/ one side of your opinion. I have the problem of making too many points and not expanding the point properly. Tbh im sick of hearing the words 'expand the point!'. But if you want the marks, you've got to. All it means is connecting your point with the case study and the question i.e. making your point SPECIFIC to the case study. Examiners call this application and in a 12/15 mark question theyd hold (say) 4-6 marks.
After you've made and expanded the first point, make the counterargument to that point to show off your knowledge of both arguments. Remember in srguments the key phrases are "if this happend this would happen because.... and ....., however if that happend it would be better for the business because [Bob would be able to use an extention stategy to keep a constant cash inflow..] <- thaat last bit was APPLIED and also used SPECIALIST TERMONOLOGY)
One point for and against would actualy be enough so long as it is (sorry to say it again) EXPANDED and APPLIED.
Finaly, finish with an evaluation. I used to just say "overall i think this would be best for the business". But you have to think higher then cthis, this WHY IS THIS OPTION BETTER? To what extent is it better? Why is it best for this particular business in this case study?
All i can say now is remember to use specialist terms like the boston matrix, cash cow, use terms such as demand and suppy e.c.t.
I am not an expert, this is basicly what ive learnt over time by practising. May not all be right but i hope it helps
