Organizations like Wal-Mart, Ikea, HSBC are keenly participating in the development of their vendors by means of training and operational support. They get their supplies customized as per their needs both in terms of time and quality.
Going a step forward Wal-Mart went a step forward in getting the operations of its vendors standardized and even certified.
An example for the same is that the fresh meet stock sold in Easyday Stores(a J.V. of Wal-Mart and Bharti for Indian markets) comes from vendors who comply with food safety standards.
They could not have introduced this category or would have maintained the standards themselves if the vendors would have provided the stock in the old fashion… the organizations trained and got their vendors certified to introduce this category which was previously untouched by so called organized retail.
