If a business built a plant to produce products without first designing a process to manufacture them, the risk would be lack of capacity without significant plant redesign. Similarly, lacking a software engineering approach and tools for designing e-business connections before creating them, can risk: 1) designing the business partnership incorrectly, 2) not implementing the connection quickly enough, or 3) having operations that cannot adapt to changes in business direction. This paper presents a software engineering tool for developing process-oriented Internet applications that implement e-business connections. It gives an approach for using this tool in conjunction with standard commercial IDEFO tools to create adaptable connections. It is organized to match a formal demonstration that shows the step-by-step usage of these tools, and cites software engineering principles that, when applied, ensure adaptability.
