SNA legacy protocol was implemented to interface with driver and vehicle information systems. Application Integration Requirements Application integration requirements were different for each of the eight organizations involved in the project. Three different interfaces for Tandem, IBM MVS and DEC from a single Windows client application were designed and developed. The networks and available communications software interfaces are unable to meet the error recovery and performance requirements of these applications. The project was forced to drop Tandem RSC middleware used in a wireline environment.
Dedicated attention is needed to take care of safety considerations.
Lack of attention to the ergonomic design could ultimately affect the overall success of the project. Properly implemented solutions can generate tangible economic savings and non-tangible benefits sufficient to justify large expenditures on such systems. This pilot project was one of the most sophisticated of its type in North America.
