The components of an iIS process system, shown in Figure 2-1, are implemented through a number of software modules running on various nodes in your computing environment. Some of the components are provided by iIS system software (iIS process engine components, process development workshops, and system management tools). Some must be developed on site and require iIS system software (process definitions and iIS process client applications). Others must be developed on-site using other software products (organization database).
