If you are in B2B Enterprise, just having a quarterly meeting with your customers vs having none can be the difference between a success and a failure for this customer.

All business are different, there is not one road to success, there are as many as successful companies. As a result non-contextual business advice is usually useless.

In B2B Enterprise also. Most companies fails not because they don't have a good product, but because they don't sell well enough
