Over-processing - making goods that are too complex as they could have been designed more simply
Defects - products that do not come up to quality standards and have to be rejected or corrected
Quality product
a good or service that meets customers’ expectations and is therefore ‘fit for purpose’
Quality standards

Prevention
Inspection
Correction and improvement
Benchmarking
Involves management identifying the best firms in the industry and then comparing the performance standards - including quality - of these businesses with those of their own business

Zero defects
the aim of achieving perfect products every time
ISO 9000
an internationally recosnised certificate that acknowledges the existence of a quality procedure that meets certain conditions
Optimal location
a business location that gives the best combination of quantitative and qualitative factors
Quantitative factors (choosing location)
these are measurable in financial terms and will have a direct impact on either the costs of a site or the revenues from it and its profitability
Site and other capital costs
Labour costs
Transport costs
Salaries
Market potential
Government grants
Qualitative factors (choosing location)
non-measurable factors that may influence business decisions
Outsourcing
using another business (a ‘third party’) to undertake a part of the production process rather than doing it within the business using the firm’s own employees
Business-process outsourcing (BPO)
a form of outsourcing that uses a third party to take responsibility for complete business functions, such as HR and finance
Insourcing
the reverse of outsourcing as it is undertaking a business function or process within the business rather than contracting it to another business
subcontracting
the practice of assigning to another business (the subcontractor) part of a contract – for example, a specialist activity that makes up part of a construction contract
Offshoring
the relocation of a business process done in one country to the same or another company in another country
Inshoring
ending offshoring contracts with overseas suppliers and returning functions or processes to business operations in the home country
Multinational
a business with operations or production bases in more than one country
Supply chain
every business that comes into contact with a particular product
Stock (inventory)
materials and goods required to allow for the production and supply of products to the customer
Raw materials and components
Work in progress
Finished goods
JIT – just-in-time stock control
this stock-control method aims to avoid holding stocks by requiring supplies to arrive just as they are needed in production and completed products are produced to order
JIC – just-in-case stock control
the stock management strategy that businesses use when they hold a high level of stocks because there is a risk of ‘stock-out’
Stock holding costs and cost of not holding stocks
Stock holding costs:
Opportunity cost
Storage costs
Risk of wastage and obsolescence
Cost of not holding stocks:
Lost sales
Idle production resources
Special orders could be expensive
Small order quantities
Economic order quantity (EOQ)
the optimum or least-cost quantity of stock to re-order taking into account delivery costs and stock-holding costs
Stock control charts
Charts that record stock levels, stock deliveries, buffer stocks and maximum stock levels over time
Buffer stocks
the minimum stocks that should be held to ensure that production could still take place should a delay in delivery occur or production rates increase
Maximum stock level
limited by space or financial costs
Calculation: EOQ of each component + buffer stock level for the item
Reorder quantity
the number of units ordered each time
Lead time
the normal time taken between ordering new stocks and their delivery
Re-order stock level
the level of stocks that will trigger a new order to be sent to the supplier
capacity utilisation

full capacity
when a business produces at maximum output
excess capacity
exists when the current levels of demand are less than the full capacity output of a business – also known as spare capacity
capacity shortage
a shortfall that occurs between the required operating capacity and the actual amount of operating capacity the system can provide.
productivity
the ratio of outputs to inputs during production, e.g. output per worker per time period
Labour productivity (number of units per worker) = Total output in a given time period/Number of employees
Capital productivity = Total output/Capital employees
level of production
the number of units produced during a time period
Make - or - buy decisions
Decision if a business should make a product themselves or buy them in
Figures they should consider
Expected volume (V)
Fixed or overhead costs directly associated with making the product (FC)
Unit direct costs of making the product (UDC)
Unit cost from an external supplier - including transport costs (UCS)
Formula:
Cost to buy (CTB) = V x UCS
Cost to make (CTM) = FC + (UDC x V)
If CTM exceeds CTB → it is more financially advantageous to buy-in or outsource
If CTB exceeds CTM → it is more financially advantageous to make ourselves
