How effective are the production plan and marketing strategy behind Glastonbury Festival?
The 2 areas of festival management that you should focus on are production and marketing.
Regarding the 2 forms, I found a social media usage poll (which can be linked to marketing) and a risk assessment (which can be linked to production).  make sure to mention those 2 forms when you discuss and analyze each area of management.
Therefore, when you analyze marketing and the marketing strategy behind Glastonbury you should also mention the social media usage poll. When you analyze production and the production plan behind Glastonbury you should also mention the risk assessment.
