Naturally, IS / IT managers pay more attention than others to technological issues in the development of new IS / IT, because there are usually internal legacy systems that work with EDI middleware to communicate with their trading partners. EDI provides a standardized data format for two computers to communicate automatically without any manual intervention. This brings a high level of transaction efficiency, but it is not very useful for communication of unstructured information, or for evaluation and negotiation processes. Migration to new IS / IT may require interacting with different web applications and non standardized data formats that may create problems with organizational intranet systems. For example, getting demand forecast information from multiple customers and incorp orating it into intranet systems would require visiting customers’ websites individually, retrieving information, checking their data formats and re entering them in internal systems. This may be a step backward in technology for retailers unless interfaces are developed to retrieve information automatically from websites and store it in intranet systems.
