Abstract
This paper presents an analysis of the critical region in furniture production.
The analysis includes quantification of incompatibility, and analysis of the causes of this
incompatibility with the Ishikawa diagram. An analysis of Parto-Lorenc was used in order
to quantify identified incompatibilities within assumed research period. In order to
determine risk associated with the occurrence of a given type of incompatibilities and its
importance for the next stage of the manufacturing process as well as for external
customer FMEA method was used.
