Business UNIT 4 - Operations Flashcards
Operations
what is the importance of setting operational objectives?
- The operations function of a business is the ‘engine room’ of the business, and like all engine, performance can and should be measured
- All business operations of whatever size and complexity should have objectives se
what are the ways of measuring quality?
Scrap/defect rates – a measure of poor quality
Reliability – how often something goes wrong; average lifetime use Customer satisfaction – measured by customer research
Number/incidences of customer complaints
Customer loyalty – percentage of repeat business
what are speed of response and flexibility targets (objectives)
Labour productivity – output per employee, units produced per production line, sales per shop
Output per time period – potential output per week on a normal shift basis, potential output assuming certain levels of capacity utilisation
Capacity utilisation – the proportion of potential output actually being achieved
Order lead times – the time taken between receiving and processing an order
how can operations of a business add value?
- Added value is equivalent to the increase in value that a business creates by undertaking the production process
- Adding value is the difference between the price of the finished product/service and the cost of the inputs involved in making it
what is labour productivity and how is it measured?
Labour Productivity = this measures the level of output achieved with a given number of employees (how efficient the workforce is). -
formula= total output / number of employees
- The higher the number the better as it means there is a higher and more efficient rate of production per employee
what are the unit costs and how are they measured?
Unit Costs (average costs) = this measures the costs of producing ONE unit/product of output
- formula= total costs (fixed costs + variable costs) / total output
- The lower the number the better as it will give you more profit (higher profit margins
– revenue is the same). Also, if you have lower costs, then businesses tend to lower prices to gain more sales. If firms were to lower the price at the same level that they lower costs, they maintain the same level of profit.
what is capacity utilisation? How is it measured?
Capacity Utilisation = the percentage of total capacity that is being achieved in a given period
- Formula= actual level of output / maximum level of output x 100
- This higher to percentage to better as it means the business is using their capacity to the best of its ability. When a business is operating at less than 100% capacity, it has ‘spare capacity’
How do businesses increase efficiency and labour productivity?
Measure performance and set targets - Streamline production processes
- Invest in capital equipment (automation + computerisation)
- Invest in employee training- Make the workplace conducive to productive effort
- Training – e.g. on-the-job training that allows an employee to improve skills required to work more productively
- Improved motivation – more motivated employees tend to produce greater output for the same effort than de-motivated ones
- More or better capital equipment (this links with the topic of automation)
- Better quality raw materials (reduces amount of time wasted on rejected products)
- Improved organisation of production – e.g. less wastage
what is cost minimisation?
Cost Minimisation = a financial strategy that aims to achieve the most cost-effective way of delivering goods and services to the require level of quality.
what is economies of scale?
unit costs fall as output increases
give me the different types of economies of scale and explain each
Technical – large-scale businesses can afford to invest in expensive and specialist capital machinery
- Specialist – larger businesses split complex production processes into separate tasks to boost productivity – by specialising in certain tasks or processes, the workforce is able to produce more output in the same time
- Purchasing – reduced costs for larger businesses in buying inputs, such as raw materials and parts, or of borrowing money because of a larger discount given to a larger purchase than smaller businesses can make- Marketing – a large firm can spread its advertising and marketing budget over a large output and it can purchase its inputs in bulk at negotiated discounted prices if it has sufficient negotiation power in the market
- Financial – larger firms are usually rated by the financial markets to be more ‘credit worthy’ and have access to credit facilities, with favourable rates of borrowing – in contrast, smaller firms often face higher rates of interest on overdrafts and loans
- Managerial – this is a form of division of labour – large-scale manufacturers employ specialists to supervise production systems, manage marketing systems and oversee human resources
what is 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. Lean production aims to cut costs by making the business more efficient and responsive to market needs.
what are the key aspects of lean production?
cell production, kaizen and time based managment
what are advantages and disadvantages of lean production?
Advantages of lean production:
- Lead times are cut- Damage, waste and loss of stocks/equipment are lowered
- A greater focus on customer needs- Improved quality through the introduction of kaizen and quality circles
- Lower costs and contribute to improved profits- Staff are more involved and potentially more motivated
- Working environments are safer and cleaner
Disadvantages of lean production:- The business may struggle to meet orders if their suppliers fail to deliver raw materials on time
- The business is unlikely to ‘bulk buy’ its raw materials and, therefore, it may lose the benefit of achieving economies of scale
- Buffer stocks are minimal and this may lead to the business having to reject customer orders requiring delivery immediately
What are the problems with operating at a higher capacity?
low quality, added workload for employees and loss of sales as they cant meet demand
what is the difference between labour intensive and capital intensive
labour intensive- requires workers rather than machines
capital intensive- requires machines rather than workers
what are some examples of technology which help to improve opperational efficiency?
Robots, communication, stock control charts and automation
what is quality?
Quality = a measure of the worth of a product, for example its durability, reliability, or reputation
what can quality help a business to gain?
Gain a competitive advantage, add brand loyalty and improve reputation and usually increase selling prices
what is quality control?
Quality Control = the process of inspecting products to ensure they meet the required quality standards (check the product at the end for any mistakes)
- At its simplest, quality control is achieved through inspection.For example, in a manufacturing business, trained inspectors examine samples of work-in-progress and finished goods to ensure standards are being met.
- For businesses that rely on a continuous process, the use of statistical process control (“SPC”) is common. SPC is the continuous monitoring and charting of a process while it is operating. Data collected is analysed to warn when the process is exceeding predetermined limits
what are the benefits and drawbacks of quality control?
- With quality control, inspection is intended to prevent faulty products reaching the customer. This approach means having specially trained inspectors, rather than every individual being responsible for his or her own work.
- Furthermore, it is thought that inspectors may be better placed to find widespread problems across an organisation.
Disadvantages of quality control:
- Individuals are not necessarily encouraged to take responsibility for the quality of their own work.
- Rejected product is expensive for a firm as it has incurred the full costs of production but cannot be sold as the manufacturer does not want its name associated with substandard product. Some rejected product can be re-worked, but in many industries it has to be scrapped – either way rejects incur more costs,
- A quality control approach can be highly effective at preventing defective products from reaching the customer. However, if defect levels are very high, the company’s profitability will suffer unless steps are takento tackle the root causes of the failures
what is quality assurance?
Quality Assurance = the processes that ensure production quality meets the requirements of customers (continuation of checking at each stage of production)
what are the advantages of quality assurance?
Advantages of quality assurance:- Costs are reduced because there is less wastage and re-working of faulty products as the product is checked at every stage
- It can help improve worker motivation as workers have more ownership and recognition for their work (see Herzberg)
- It can help break down ‘us and them’ barriers between workers and managers as it eliminates the feeling of being checked up on
What is total quality management?
a specific approach to quality assurance that aims to develop a quality culture throughout the firm
