Burning process source HCP . The application of Petri Nets made it possible to collect valuable information about the structure of production process and provided suitable basis for the simulation. However the obtained output was not sufficient to make a final decision about real process reengineering. Therefore an additional analysis with the help of another reengineering methodology was required. 4. Discussion of approaches to reengineering On the basis of literature study five different approaches to reengineering can be identified Cempel 2005 Pacholski et al. 2009 M. Hammer and J. Champy approach Hammer Champy 1993 . Manganelli and . Klein approach Manganelli Klein 1998 N. M. Tichy and S. Sherman approach Tichy Sherman 1993 . Davenport approach Davenport 1993 J. Durlik approach Durlik 1998 The first two approaches can be classified as of a consulting type the third approach is purely managerial. The remaining two approaches can be classified as mainly academic Cempel 2005 . Hammer and Champy Hammer Champy 1993 . present an approach according to which reengineering is rejecting procedures used before and looping at work needed to manufacture a product or perform a service .
