The necessary information for the next part of thesis was taken from the corporate internal data and from the regulated conversation with several experts of the company. For mapping out the times of the workshop processes was used data from the entire year 2016. This technique helped with analysis of present state and to found out key problems with excessively long time duration of repairs.
