The application controller concept addresses DPS/end user interface problems in applications of a stable and repetitive nature. These interface problems arise both during development and operation of an application. To tackle these problems the application controller concept proposes a methodology for the application development process which is based on a state networking technique. One main aim of this methodology is to involve the end user in the definition and design of his application to a high extent. This paper presents the experience gained with the methodology in the course of a major application development project at Lufthansa. The application controller concept is also a proposal for a software system which supports the actual operation of the application at run time. The last two sections of the paper will elaborate on some of the properties of this software system.
