  Modeling of work systems occurs for all sorts of reasons. Requirements need
to be expressed. A pre-existing situation may need to be charted and analyzed.
Early design decisions may be captured using architecture principles. Detailed
design may be worked out. We all regard these activities as essentially being
forms of modeling. In the work systems modeling library, we consider work
system engineering from a modeling perspective. In the field of work system
engineering, a whole plethora of modeling methods is available to system
engineers and architects. Each of these methods can be used to model some
(aspects) of a domain related to an existing and/or a planned work system. The
aspects may refer to requirements, architecture, design, processing, data, etc,
etc. In other words, these methodes are essentially all intended to model
different aspects of work systems and/or their context. The aim of the work
systems modeling library (WSML) is to bring together methodical knowledge
concerning the modeling of work systems.
