ABSTRACT
When dealing with applications development of open systems, the issues are numerous and varied. New systems are being developed from scratch based on new concepts; ideas that once could never be translated into a system can be. This chapter provides a personal look at the integration process and describes the experiences of one project manager in the integration of legacy systems into a new open systems environment. Integrated system development involves issues such as performance, communication, and compatibility. The chapter describes the integration effort in which the issues centered on seven major factors: user specifications, system performance and response time, communications, data accuracy, resource contention, ergonomics, and legacy systems. It discusses CPTrade, a proprietary offering system developed by the author/project manager's team at CS First Boston. CPTrade was developed in a client/server environment and completely replaced a mainframe legacy system, with a significant increase in functionality.
