What causes your customers to fail?

You have laid out a compelling vision based on your customers' success. You are passionate about your vision. You are creating a brand that is executing against your vision. You are well on your way to amazing growth. So what is stopping you? The better question might be what is stopping your customer?  It is important to recognize the factors that are causing your customers to fail and find a way to overcome them.  It could be something simple like lack of parking or something more significant, think about shipping costs and Amazon.com, which led them to create Prime.  There is also the frequently mentioned case of Febreze, which according to its Wikipedia entry,

"The product initially sold poorly until P&G realised that people had become accustomed to the smells in their own homes, then switched to linking it to pleasant smells and cleaning habits to produce the successful product."

Regardless of the cause, if there is something that is causing your customers to fail, you have to find a way to address it.
