Recommendations


  • Geographic Performance
    Asia is the best performing region and further investment in this region should yield substantial returns.

Oceania is the worst performing and strategies should be explored for expansion in this region.

  • Catalogue Offering
    The catalogue currently only offers English language films and should be expanded to include more localised content.
  • Customer Loyalty
    Development of a rewards program for loyal customers to encourage repeat rentals.
