Abstract This paper describes methods and tools developed and in use, in a large engineering company when process design forms part of a concurrent plant design project. One of the most important aspects is how to handle the information flow between different disciplines. The methods and tools to solve the information-sharing problems are using new ICT technologies such as the Extensible Markup Language (XML) and the Web. Also the measuring of concurrent plant design and engineering performance as for the information existence, accuracy, completeness and timing is discussed. As a case example of how the process design can be integrated with other disciplines by using new ICT technology, Jaakko Pöyry Oy's MODE concept is described.
