The look and feel of the interfaces are tuned during the Interface Definition subphase. The menus and windows are adjusted to fit the current requirements of the workflow in the organization. Authorization is added, allowing groups of users access to only that information required for their role in the organization.

In order to communicate easily and effectively with the user, the core system usually requires further work on the user interface. The employees' roles in the organization are discussed, to define how they will use the system, and levels of authorization are defined. Generated screens and functionality based on the core system are grouped together to support these roles, and then fine-tuned. Performing these tasks on a stable core system minimizes costs, for example, if you have to make repetitive screen adjustments when base data significantly alters in content.
