A system for producing a process advisor application uses a process mapping program, a compiler and a program such as a Java servlet to produce a process advisor application. The process mapping program is used to create a decision tree, and the compiler compiles the decision tree into a data file. The data file is then converted into one or more computer viewable documents, such as web pages.
