I recently posted about inventory strategies and specifically about "leftover" or unsold inventory and suggested 3 reasons why there are leftovers. The first reason is the Self-Fulfilling Prophecy or SFP.
What is the SFP?
SFP refers to the fact that it is "easier" to sell things that you have sold before than it is to locate and suggest new alternatives. Thus, what you have sold before is replicated for the next campaign. All you need to do is change the flight dates and resend the IO. No fuss, no muss.
What's wrong with this, ...
