- in the right quantity
- and the right quality
- in the right place
- at the right time
- for the right customer
- at the right cost
What is the difference between outsourcing and offshoring?
Outsourcing: third party provider
Offshoring: transfer of specific processes to lower cost location in other countries (still own it)
What is back- and nearshoring?
Backshoring: move activities back to original home market
Nearshoring: move offshored activities to countries closer to home market
What are order-losing sensitive qualifiers?
Order qualifiers that are more critical than others in terms of the outsourcer’s requirements
How is the framework for evaluating potential outsources?
What are the four stages of outsourcer-outsourcee relationship?
- Master-servant stage: low cost is main driver
- Consultative stage: outsourcer consults with outsourcee on regular basis
- Peer-to-peer relationship stage: ideal stage, synergies, long-term, win-win
- Competitive stage: outsourcee takes the lead and starts competing with outsourcer
What are the four primary modes of integration within a supply chain?
- Internal
- Aim: integrate communication and information systems
- Backward (external)
- Forward (external)
- Forward and backward (rare) (external)
What is the difference between supply chain integration and collaboration?
Integration: alignment and interlinking of business processes
Collaboration: relationship between supply chain partners developed over a period of time
What is vertical and horizontal collaboration?
Vertical collaboration: between suppliers and customers (easiest)
Horizontal collaboration: between competitors and supply chain actors
What is the unionist view?
That logistics is part of the wider entity which is SCM (adopted by the book)
What is craft production?
Goods customised for individual customer needs
What is just-in-time (JIT)?
A system where inventory is pulled downstream through the system, which prevents stockpiling and inefficiency.
What are the seven key areas of the Toyota Production System (TPS)?
- Overproduction
- Waiting
- Transportation
- Inappropriate processing
- Unnecessary inventory
- Unnecessary motion
- Defects
What is MTS and MTO?
Made-to-stock (push + inefficient) and made-to-order (pull + Toyota)
What is an agile supply chain?
‘To a truly agile business demand volatility is not a problem; its processes and organisational structure as well as its supply chain relationship enable it to cope with whatever demands are placed upon it.’
In the above figure, the supply chain to the right is better able to cope with demand volatility, as it has more options in the second step to steer production towards another product.
Professor Christopher: ‘the ability to respond rapidly to unpredictable changes in demand’
What is postponement?
A production philosophy used for mass customisation, which involves the reconfiguration of product and process design so as to allow postponement of final product customisation as far downstream as possible
Also known as: ‘delayed product configuration’, ‘delayed product differentiation’ and ‘late stage customisation’
What is a stock-keeping unit (SKU)?
It is a unique version of a product in terms of size, packing, colour etc.
What are functional products?
- Predictable demand
- Long product life cycles
- Low variety
- Long lead times
Requires an efficient supply chain
What are innovative products?
- Unpredictable demand
- Short product life cycles
- High variety
- Short lead times
Requires a responsive supply chain
What is the taxonomy for selecting global supply chain strategies?
What is the bullwhip effect and what are the five causes?
When the inventory levels fluctuate along the supply chain, as small fluctuations in end customer demand result in amplification of demand upstream.
- Non-zero lead times
- Demand signal processing
- Order batching
- Price variation
- Rationing and gamin
What are the different types of simulation?
- Stochastic or deterministic
- Static or dynamic
- Discrete event and/or continuous
What is a stochastic and deterministic model?
Stochastic: Has a least one input variable that is random
Deterministic: has no random input variables
What is a static and dynamic model?
Static: do not include the passage of time (presents at a particular point in time)
Dynamic: includes the passage of time and represents systems as they change over time
What is a discrete and continuous simulation?
Discrete: changes occur at discrete points in time triggered by events (e.g. inventory)
Continuous: the state variables change continuously with respect to time and therefore observations are collected continuously (temperature)

- Design and run experiments
Who is the consignor and consignee?
Consignor: sends the consignment
Consignee: receive the consignment
What types of logistics service providers (LSP) exists?
- Hauliers or trucking companies: carry freight
- Freight forwarders/agents/brokers: travel agents (just arrange transport for goods and not people)
- Non-vessel-owning common carrier (NVOCC): companies who consolidate smaller shipments from various consignees into full container loads which the NVOCC then takes responsibility for (agent+principal)
- Couriers: immediate delivery of products
- Integrators: big companies like DHL, UPS, FedEx etc. Carries all the responsibility from consignor to consignee
What are the two common meanings of shipping?

What is the purchase price variance (PPV)?
A measure of the variance between the actual price paid versus the standard cost of the item. The standard cost of an item would be included in a bill of material (BoM) for a particular product and is used to calculate the product cost.
What is inventory turnover?
The higher the better
What are the two broad costs associated with inventory?
- Procuring the inventory
- Money spent to process a procurement order
- Money spent to actually buy the inventory
- Holding the inventory
What are the notations of inventory?
D: Annual use of a particular item, in number of items per year
S: Order-processing cost, in $/order
p: Price per item, in $/unit
H: Holding cost per unit per year, in $/unit/year
Q: Number of items ordered in one purchase order, in units
T: Time periods between purchase orders in fraction of a year
SS: Safety stock, in units
L: Lead time, in fraction of year
I: Current inventory on hand, units
TAC: Total annual cost
What are the total annual cost, TAC (of inventory)?
Total Annual Cost (TAC) = Purchase cost + Holding cost + Order-processing cost
TAC = pAD + (SS+Q/2)H + (D/Q)S
What is the economic order quantity?
The best order quantity which is the lowest cost balanced between order processing costs and inventory holding costs.
What is the reorder point (ROP)?
A predetermined level at which orders are issued when the inventory is depleted to that level.
ROP = D * L + SS
What is the periodic inventory control system?
A system where orders are reviewed periodically after the passage of a fixed time, T. Reorder at fixed time intervals (convenient).
What are the four strategies to manage and reduce inventory volumes?

- An ‘L’ flow operation with conveyor
What are the four value adding activities of warehouse handling?
- Creating bulk consignments (transport economies)
- Breaking bulk consignments (transport economies)
- Combining freight (production postponement principle)
- Smoothing supply to meet demand (holding buffer stock to decouple lean production from the agile supply of goods to the market)
If none the freight requires none of those, then storage should be avoided (costly and non-value adding)
What are some of the order picking methods, and when are they most useful?
- Pick-to-order (low-volume operations)
- Batch picking (large-scale operations)
- Pick-to-zero/pick-by-line
- Zone picking/pick-and-pass
- Wave picking

- Supply-side information (when will freight be delivered, etc.)
What are the key drivers of information technologies?
- Complexity

- Diffusion
- Velocity
- Accuracy
What are the four barriers to information visibility and transparency?

- Financial
- Technical
- Organisational
What are dependent and independent demand?
Dependent: part of an order for multiple interrelated items (complete bicycle → bicycle pedals are demanded, but dependent on the order of the complete bicycle)
Independent: ordered independently of any other product (bicycle pedals)
What is Materials Requirements Planning (MRP)?
The tool for planning and controlling the manufacture and assembly of orders with dependent demand (push system + dependent demand) - software
What is MRPII?
Manufacturing Resource Planning which utilises the core functionality of MRP but integrates business function beyond manufacturing and logistics to include finance, procurement, marketing, sales, etc.
What is CPFR?
Collaborative planning, forecasting and replenishment.
CPFR fills the inter-organisational gap that ERP cannot, and is more than just a software application. It is a new collaborative method of scheduling logistics between suppliers and customers.
Time, complexity, scale and substantial investments are required, and are therefore constraints. Most often used by leading supermarkets and their top-suppliers.
What is VMI?
Vendor managed inventory.
It enables supply to more accurately and precisely meet demand, and thus avoid things such as the bullwhip effect.
