I find it fascinating that markets can be so dynamic. In some markets, your customer base can change from month to month. Just making sure customers are aware of your existence at that point of entry can make all the difference in success or failure. The example Kaufman cites is learning a newborn on the way. He explains that this information marks a clear point of entry into the infant and childcare markets. If you want to zoom in even closer; once the baby is born, there are entries and exits into various specific markets such as clothes and toys from month to month.
This point of entry variable puts time and space constraints on some markets.
This means that, as entrepreneurs, you have to keep your eyes on other marketing measures such as receptibility and addressability of your audience to ensure that you aren’t wasting time or resources. If your market has a clear point of entry, then it’s safe to assume that it also has a point of market exit. Looking for sales opportunities at these entrance and exit points can be successful strategies for revenue generation.
