Market Sizing: in-store photo printing kiosk

Hi there,

Here's what I would do

• Estimate # of daily customers per Walmart
  • Visualize # of cashiers (I always think of 10-20)
  • Estimate customer churn per cashier (around 1 every 3 minutes, so 20/hour)
    • You can get "fancy" with this if you like. Also want to multiple by a % of "overcapacity" i.e. customers are always lining up
• Take a % of these daily customers that would use photo printing kiosk (hint: It's a small %)
  • You can also get "fancy" here in terms of breakdown...probably not worth it
• For customers that print, estimate # of photos
  • Here, you should get "fancy"...have a breakdown of % users by job...small job "single photo" (1-2), medium job multi-photo (~5-10) and big job photo album (~25-50)
• Multiply out (and multiply by cents per photo if relevant)
• Estimate # of Walmarts in the region and multiply by the above

The key here is breaking things down based on 1) what makes sense and 2) what you can actually reasonably assume.

Hope this helps!

Hello!

It´s a good start, but things you need to take into consideration:

• 50% of the population is way too much (you need to include here all children, very old people, etc.)
• Instead of population in general, I would use households, since it´s much easier to calculate the visits to the supermarket per household (=family) than per individual -in line with the previous point-.
• Once you have the households that go to your store, you need the TEMPORAL component. For instance, assuming each family prints in a Wallmart every 3 months

Hope it helps!

Best,
