8.1 Business scenario

In this scenario, ABC Electronics consists of multiple Retail stores and Wholesale departments. The Retail stores get their supplies from the Wholesale departments and have a need to request the delivery dates of those supplies.

Currently there is no integration of the Retail and Wholesale applications. All interactions between the two are done over the phone or by mail. In this scenario, a solution must be found to allow the Retail stores to request delivery dates from the Wholesale departments.

The solution requires the following elements:

  • A central access point for all services inside the enterprise.

  • Decoupling Retail store functions from the Wholesale department functions so that changes made to the Wholesale department systems or their location do nor require a change to the Retail store systems.

  • A central security control point that controls access to the Wholesale department services.

  • Protocol conversion between the Retail store systems and the Wholesale department service providers to accommodate the addition of new services. The transition of protocols used between the Retail and Wholesale systems must be transparent.

ABC Electronics is planning to implement the solution in three stages:

  • Stage 1: Basic integration:

    The Retail system requests either the service of Wholesale1 or the service of Wholesale2, therefore the Retail system has to know which Wholesale holds the part it needs.

  • Stage 2: Enhanced integration:

    ABC Electronics enhances this solution, so that the Retail system no longer needs to know where the part is.

  • Stage 3: Extended enterprise:

    ABC Electronics wants to allow external Retail systems to get delivery dates from the Wholesale departments and to plan for allowing internal Retail systems to get delivery dates from external Wholesale suppliers.
