Need help coming up with a promotion situational analysis for a marketing campaign for Dior Luxury Cosmetics line.

Our idea for the marketing campaign includes an experiential kiosk set up in higher end malls across the United States that promotes Dior's new or seasonal fragrances that allows a person to identify their gender and stick their hand in the Kiosk to sample a random fragrance at that occasion for free in order to bring Dior earned media and promote new/seasonal lines. (Note: unlimited budget in this situation.)

My question primarily refers to what would be needed to evaluate the internal and external analysis regarding this promotion and what can enhance or hurt it's potential to be successful.
