2. Inventory related costs –in transit, in
storage or WIP
3. Transportation costs – vary depending on
mode of transport used, product and size
Trade off between the various cost factors

Question: When would you have higher
reorder point than usual?
reorder point than usual?
- Unreliable suppliers
- Huge variations in order lead time
- Large fluctuations in C-demand
Thus, have to increase safety stocks as well … increased
inventory costs …
58. Just in time - JIT
Right products at the right quantities just when they are required.

59. KANBAN
Concept that implies that the
organisation holds LOW
inventory levels and NO SAFETY
STOCK because carrying
inventory tied up working capital.
61. NB RE JIT:
1. Close relations between supplier
and customer
2. Attention given to quality
3. Organisations must have adequate
storing facilities
4. Organisations must have adequate
transport options
5. Suppliers must deliver a reliable
service
6. Short and reliable order lead times
7. Purchasing quantities are reduced
62. Advantages of having JIT:
1. Lower inventory levels = reduced
stock holding cost
2. Low/ no safety stock levels =
reduced stock holding cost
3. If organisation and supplier have
good relationships … leads to
higher quality (cannot send back
due to time issue)
63. Disadvantages of having JIT:
1. Risk of running out of stock due to
late deliveries
SO – SELECTING SUPPLIERS ON
FOLLOWING CRITERIA:
a) Quality of goods they provide
b) Their reliability
c) Their capability
d) Sound financial position
e) Good location
f) Stable labour force
