In a global market the customer selects the supplier, which can provide short and reliable delivery dates. Delivery dates largely depend on duration of lead times, therefore the basic requirement of customers can be fulfilled only by gradual transition from workshop production type to flexible manufacturing systems (reduction of number of operations, reduction of transition times, overlap of operations) or by a suitable method for reduction of lead times of orders in a current workshop production type (without big investments). The article describes methods for reduction of lead times, the emphasis being given to the reduction of lead time of operation; the method is based on the analysis of current order flow through workplaces, computer-aided design of flow diagrams, definition of average lead times of workplaces, and finding the critical workplaces that have the biggest influence on lead times. Three-line ABC analysis is used to find out the critical workplaces. Presented are the results of lead time reduction in a tool production department which exports 30% of its production, 5% of its production is sold on domestic market and 65% of production is used by the company itself. The company has a strong competition on domestic and global markets and the only surviving strategy seems to be in shortening delivery dates (i.e. shortening lead times of orders).
