The Infographic below shows how eComerce is seen from the Customer point of view. To me it also shows how retail fulfilment may well be a limiting factor. Customers are expecting an Omni channel approach more and more. We are now getting to the level of high impact high cost logistics. You can already see retailers wanting to charge for instantaneous services . Amazon Prime is a case in point. Networked delivery systems require investments and the providers will not be interested in delivering if there is no chance of a profit. I will be interested to see how the trade off between over-delivery based on service and under-delivery based on cost will turn out this year.
