Process orientation in production and business administration is a major means of increasing flexibility and speed while decreasing costs. During the past years the notion of human resources as a potential and means of ensuring flexibility in decentralised organisations gained importance. Even though systematic approaches to modelling and design of business processes and process organisation do exist, they mostly are related either to the derivation of targets on a strategic enterprise level or to specification of information technology and structures. Conversion of strategic targets into design of process activities at an operational level is usually not done in any systematic way and leaves a gap in existing methodology. This paper presents a human oriented approach to analysis and conceptual design of activities within a business process reengineering framework and its application to shop floor management.
