what is inventory management
the sourcing and storage of raw material or supplies of finished goods for resale
consequences of overstocking (5)
- suppliers could go out of date if they are stored for too long
- suppliers could go out of fashion before they are used
- too many suppliers leaves a risk of theft by staff, customers or thieves
- the business may have to pay for stockholding costs such as insurance and security
- the opportunity cost of money being tied up in inventory which could be better used elsewhere in the business
consequences of under stocking (4)
- the business may run out of inventory and be unable to continue production or carry on selling
- the business may not benefit from bulk buy discounts due to making smaller orders
- may be no goods to sell resulting in a bad reputation and customers not returning
- may be an increase in delivery costs since many smaller deliveries have to be made
Features of inventory management control systems (6)
- maximum/economic inventory level
- minimum inventory level
- re-order level
- re-order quantity
- lead time
- buffer inventory
maximum inventory level description and justification
- this is the most amount of inventory that should be held
- avoid consequences of over stocking
minimum inventory level description and justification
- this is the least amount of inventory that should be held
- avoids consequences of under stocking
re-order level description and justification
- level when inventory is re ordered
- avoids running out of inventory
re order quantity description and justification
- amount that is ordered
- ensures quantity ordered is not too much or too little
lead time description and justification
- time taken between an order being made and inventory arriving
- as short as lead time as possible allows a businesses to react to rush orders
buffer inventory description and justification
- this is the extra inventory below the agreed minimum to be used in emergencies
- this ensures that production doesn’t stop and sales continue to be made
just in time production advantages (5)
- allows production to flow smooth as there is no wastage as all inventory is used for production
- no money is tied up in inventory improving cash flow and working capital
- no warehouse is required saving costs
- the business is more responsive to changing external factors
- no theft
just in time production disadvantages (4)
- if deliveries were late then the business willi face the negative consequences of under stocking
- requires excellent relationships with suppliers to work effectively
- relies on good infrastructure between business and suppliers
- no room for error in production
Centralised storage advantages (4)
-specialist staff are employed to maintain inventory improving speed and security
- massive amount of inventory can be stored benefiting from economies of scale
- may be cheaper to store inventory in one large warehouse
- easier for suppliers to deliver inventory as centralised warehouses are often located close to infrastructure
what is centralised storage
storing inventory in one location in a large warehouse
what is just in time production
when supplies are only ordered when they are required for production or when an order is placed by a customer
centralised storage disadvantages (4)
- inventory has to be delivered to each department causing delays
- specialist staff need to be employed to maintain inventory which increases costs
- specialist equipment needs to be purchased and maintained
- JIT is more efficient
what is decentralised storage
when inventory is stored in many smaller warehouses
decentralised storage advantages (3)
- inventory is close at hand when needed when needed
- more responses to local needs
- smaller inventories result in no negative consequences or overstocking
decentralised structure disadvantages (6)
- can lead to wastage or theft of inventory as security is not as good
- inventory control can lead to clumsiness or inefficiency due to staff shortage
- each department may handle inventory differently leading to inconsistencies
- smaller amount of inventory results in negative consequences of under-stocking
- harder for suppliers as they have to make lots of smaller deliveries
- maybe be expensive to rent out many different and smaller warehouse’s.
computerised inventory advantages (5)
- inventory balances are automatically updated
- can be linked to sales so it updates inventory when an item is sold
- accurate and constant allowing for automatic re ordering
- can highlight seasonal shifts
- staff who want to steal will be less likely as they know they are monitored closely
computerised inventory disadvantages (3)
- costs a lot to install and maintain
- money and time must be invested to train staff to operate the system efficiently
- cashes or breakdowns can hold up re orders and production
what is the role of a logistics manager (7)
- planning inventory using production and sales budget
- organising resources needed such as staff
- commanding staff
- co-ordinating supply chain, channels and methods of distribution so deliveries are made on time
- delegate inventory to different warehouses

- motivating staff
what are sales budgets
- providing a target amount of sales so staff can aim towards this and increase productivity
- motivates sales staff to reach targets
what are production budgets
- plan production so there are enough goods to meet demand
- allow enough raw material to be purchased so there is no under stocking
- allows for not to many goods to be purchased so there is no over stocking
