3.4 - Operations Flashcards
What are the features of operation in a business?
- responsible for actual production of goods/services
- managing the process of converting inputs into outputs that meet the needs of customers
- getting the right goods/services to the customer
- helps to measure the efficiency with which this is achieved
What are the features of costs in a business?
A business needs to keep costs low to be competitive with other stores
What is quality as an operational objective?
Concerned with satisfying and exceeding customer needs
How is quality measured?
- customer satisfaction ratings
- customer complaints
- product returns
- wastage rates
- punctuality
What is speed of response as an operational objective?
The time it takes for the customer to receive a product or service
Product flexibility
the ability to switch production from one product to another
Volume flexibility
the ability to change the level of output according to changes in customer demand
Mixed flexibility
The ability to adapt to provide alternate versions of particular goods or services
Delivery flexibility
the ability to adapt quickly to changes in the timing and volume of deliveries to customers
dependability for services?
the consistency of quality or the punctuality of delivery
dependability for products?
measured in terms of whether the product is durable, long-lasting and unlikely to breakdown
what is adding value as an operational objective?
the process of increasing the worth of resources by modifying them, it is the difference between the price of a finished product/service and the cost of the input involved making it
how can distribution and retailing add value?
brining the product within easier reach of the customer
how can marketing add value?
creating a USP based on image and branding
why are environmental objectives becoming increasingly important?
- many businesses recognise they have a duty of care for the environment
- stakeholders have an expectation that businesses will demonstrate a positive attitude in terms of the environment
- many environmental objectives will allow the business to save costs
What are all the operational objectives?
- operation
- costs
- quality
- speed of response
- flexibility
- dependability
- adding value
- environmental objectives
What are the INTERNAL influences on operational objectives and decisions?
- corporate objectives
- finance
- human resources
- resources available
- nature of the product
What are the EXTERNAL influences on operational objectives and decisions?
- market factors
- competitor’s actions and performance
- technological change
- economic factors
- political factors
- legal factors
- environmental factors
- suppliers
How does corporate objectives influence operational objectives and decision?
the operations department must ensure that its objectives and decisions are consistent with the corporate objectives of the business
How does finance influence operational objectives and decision?
they rely on considerable expenditure on capital equipment or R&D and sufficient finance to implement decisions
How does HR influence operational objectives and decision?
the skills, training and motivation of a business’ HR will have a major impact on operational objectives. If there are weaknesses in HR, less ambitious objectives will need to be set and effective decisions made
How does ‘resources available’ influence operational objectives and decision?
if the business is well resources with equipment and well-known brands, then it is easier to produce high quality products cost effectively
How does ‘nature of the product’ influence operational objectives and decision?
some products are suited to mass production, while others require individual methods of production. The impact of the product on the environment will also depend on the nature of the product.
How do market factors influence operational objectives and decision?
if demand changes, the business may need to modify its production levels. If sales are declining, it may introduce new products
How does ‘competitor’s actions and performance’ influence operational objectives and decision?
if a competitor has a successful new product a business may introduce its own new product
How does technological change influence operational objectives and decision?
Technology can affect a business’ costs, the quality of its products, and levels of productivity within the business. These factors are key performance targets for operations management and therefore is, arguably, the most important factor. Decisions on methods used can also be modified if technology changes
How do economic factors influence operational objectives and decision?
Interest rates are one economic factor that has a major impact on operations management objectives and decisions. The effectiveness of operations management is dependant on capital investment, and if interest rates increase, this can hinder the success of operations management in two different ways.
How can interest rates hinder the success of operations management?
- it can increase costs by increasing the interest paid on loans, therefore reducing profitability. As a result, the introduction of new machinery may be delayed, reducing the efficiency of production
- it may reduce sales levels as people cannot afford loans. This will mean lower output and so some targets, such as low unit costs, will be harder to achieve because bulk-buying opportunities have been reduced
How do political factors influence operational objectives and decision?
minimising production costs: this can cause conflict with politicians, who may disagree with the methods used to reduce costs, especially if this involves exploitation of workers or unsafe working conditions
How do legal factors influence operational objectives and decision?
the potential for health and safety risks, the operations management function is heavily controlled by legislation
How do environmental factors influence operational objectives and decision?
as a result of environmental legislation and pressures, firms are now much more closely controlled in terms of the products they make, the raw materials they use, and the processes in their factories
How do suppliers influence operational objectives and decision?
most businesses work closely with suppliers to ensure flexibility, high quality and relatively low-unit cost materials. A supplier that delivers these three factors can help a business to achieve its operations management targets and to compete effectively with rivals
What does analysing operational performance mean?
measuring how the business is performing in relation to its operation objectives
ways to measure operational performance
- labour productivity
- unit costs
- capacity
- capacity utilisation
What is labour productivity?
the amount a worker produces over a given time
why is labour productivity important?
- usually a significant part of total costs
- business efficiency and profitability are closely linked to productive use of labour
- in order to remain competitive, a business needs to keep its unit costs down
how to calculate labour productivity
labour productivity = output in period ( units ) / no. of employees at work
How to calculate labour cost
labour costs per unit = labour costs / output (units)
What happens to labour productivity when there is a higher output per employee?
It increases
What happens to labour productivity when there is a lower output per employee?
It decreases
Factors influencing labour productivity
- extent and quality of fixed assets ( e.g equipment, IT systems)
- skills, ability and motivation of the workforce
- methods of production organisation
- extent to which the workforce is trained and supported (e.g working environment)
- external factors (e.g reliability of suppliers)
How can a business increase labour productivity?
- introducing new technology to speed up the production process
- modifying the production process so that is operates more efficiently
- recruiting workers with better qualifications and motivation
- implementing new approaches to improve workers’ motivation
- providing better training for the workforce
- improving the flexibility of operations so that less time is wasted
Potential problems of increased labour productivity
- potential ‘trade-off’ with quality
- potential for employee resistance (e.g introduction of new technology)
- employees may demand higher pay for their improved productivity
Fixed costs
costs that do not vary with the level of output / production e.g rent, salary, insurance costs.
Variable costs
costs that vary directly with the level of output / production e.g raw materials, packaging, delivery costs
Total costs calculation
fixed costs + variable costs
unit costs
the average production cost per unit
how to control unit costs
- change suppliers
- use cheaper resources / materials
- improve the production process
- reducing waste
capacity
the maximum total level of output at production that a business can produce in a given time period.
the ideal capacity will depend on
- the level of demand for a product
- flexibility of production lines
- seasonability of demand/output
- implications of failure to meet demand
- opportunities for sub-contracted or outsourced production
- availability of staff and resources
Capacity utilisation
this measures the extent to which a business is using its production potential
it is the % of total capacity that is actually being achieved in a given period
capacity utilisation calculation
capacity utilisation = (actual level of output / maximum possible output) x 100
what does higher capacity mean
the more resources that are being fully utilised
Low capacity utilisation may be a concern because…
- suggests relatively low demand
- likely high cost per unit because the fixed costs are not being spread over many units. This means a high fixed cost per unit which may result in low profit margins
What is bad if if capacity utilisation is 100%
No scope for maintenance or repair. The business may also find that it cannot respond to sudden orders or deal with emergency situations.
When can capacity change?
- when a machine is having maintenance problems (reduced)
- labour; by working more production shifts/overtime, capacity can be increased
- seasonal or unexpected changes in demand (easter eggs in Nov & Dec before shipping to shop after Christmas)
The costs of capacity are…
- equipment; production line
- facilities; building rent, insurance
- labour; wages & salaries involved in production or delivering a service
How can a business work at more than 100% capacity utilisation
- increasing workforce hours (extra shifts, encourage overtime : temp. staff)
- sub-contract some production activities (assembly of components)
- reduce time spent maintaining production equipment
Problems working at high capacity
- negative effect on quality (production is rushed. less time for quality control)
- employees suffer (added workloads & stress, de-motivating if sustained for too long)
- loss of sales (less able to meet sudden or unexpected increases in demand, production equipment may require repair
Lean production
An approach to management that focuses on cutting out waste, whilst ensuring quality. This approach can be applied to all aspects of a business - from design, through production to distribution.
What is lean production in a nutshell…
- doing the simple things well
- doing things better
- involving employee in the continuous process of improvement and as a result, avoiding waste and therefore reducing costs
Why do businesses need to cut out waste
waste = cost
Examples of waste in a business
- over-production
- waiting time
- transport
- stocks
- motion
- defects
How is over-production waste in a business
making more than needed; leads to excess inventories which may then become unsavable
How is waiting time waste in a business
equipment and people standing idle waiting for a production process to be completed or resources to arrive
How is transport waste in a business
moving resources (people, materials) around unnecessarily
How is stocks waste in a business
often held as an acceptable buffer, but should not be excessive
How is motion waste in a business
a worker who appears busy but is not actually adding any value
How is defects waste in a business
output that does not reach the required quality standard - often a significant cost to an uncompetitive business
Effective lean production requires…
- good relations with suppliers
- committed, skilled and motivated employees
- a culture of quality assurance; continuous improvement & willingness to embrace change
- trust between management and employees
Methods of lean production …
- just in time production (JIT)
- cell production
- time based management
- simultaneous engineering
Just in time production
JIT aims to ensure that inputs into the production process only arrive when they are needed
How does JIT work?
- based on a ‘pull’ system of production, customer orders determine what is produced
- requires complex production scheduling - achieved using specialist software to connect production dept with suppliers
- requires close co-operation with high quality suppliers
Advantages of JIT production
- lower stock holding means a reduction in storage space which saves rent and insurance costs
- as stock is only obtained when it is needed, less working capital is tied up in stock
- less likelihood of stock perishing, becoming obsolete or out of date
- less time spent on checking and re-working production as the emphasis is on getting the work right first time
Disadvantages of JIT production
- there is little room for mistake as minimal stock is kept for re-working faulty products
- production is highly reliant on suppliers and if stock is not delivered on time, the whole production schedule can be delayed
- there is no spare finished product available to meet unexpected orders, because all products is made to meet actual orders
- a need for complex, specialist stock items
Cell production
a form of team-working where production processes are split into cells. Each cell is responsible for a complete unit of work
Advantages of cell production
- closeness of cell members should improve communication
- workers become multi-skilled and more adaptable to the needs of the business
- greater employee motivation, from variety of work, team-working and responsibility
- quality improvements as each cell has ‘ownership’ for quality on its area
