  3. 3. Business process maps The first geographical maps date back to the 7th Millennium BC. Since then cartographers have improved their skills and techniques to create maps thereby addressing problems such as clearly representing desired traits, eliminating irrelevant details, reducing complexity, and improving understandability. PAGE 2
  4. 4. Example of a map Road map of The Netherlands. The map abstracts from smaller cities and less significant roads; only the bigger cities, highways, and other important roads are shown. Moreover, cities aggregate local roads and local districts. Also not use of color, size, etc. PAGE 3

  18. 18. Navigation• Whereas a TomTom device is continuously showing the expected arrival time, users of today’s information systems are often left clueless about likely outcomes of the cases they are working on.• Car navigation systems provide directions and guidance without controlling the driver. The driver is still in control, but, given a goal (e.g. to get from A to B as fast as possible), the navigation system recommends the next action to be taken.• Operational support provides TomTom functionality for business processes.
