Have a cup of coffee! Deducing usability problems in a structured way with occurrence/severity diagrams

The complex interface of a coffee vending machine is tested for usability. To analyse the results, a new structured method is generated. This method involves the use of sticky notes, clustering of information and application of occurrence/severity diagrams. This new method is explained and the results are discussed.
