P(O)LT Purchasing (Order) Lead Time = Purchasing Flow Time
Order Delivery Date - Material Order date = Purchase Flow Time
The time to receive the order is opened by the relevant group.
Although it varies on a sectoral basis, the general processes are;
Order confirmation
Bid collection
Tender (if there is no Institutional Agreement)
Contract (if not available)
Payment confirmation
Payment
Production
Foreign Logistics
Handling
Quality control
Internal Logistics
etc.
Ways to shorten the Purchasing Flow Time;
Development of stock tracking systems
Simplification of procedures
Establishment of decision support systems to anticipate seasonal needs
Automation of orders by including them in the Minimum Stock system
Preventing orders from opening on weekends (An order opened on Friday can only be processed on Monday.)
Reducing the number of transactions thanks to order consolidation
Developing the supplier portfolio by category
Improving communication with suppliers
Ultimately, looking at the process as a whole, carefully overhauling all stages, and carefully evaluating the feedback to be received from internal and external stakeholders in this process (Using people's brains, not just their hands)
