Operations Flashcards
What is added value?
The difference between the selling price of a product and the cost of bought in materials and components.
How is added value different to profit?
Profit considers all costs.
How can a business increase added value?
-Cheaper raw materials.
-Customer loyalty and brand image.
-Increase selling price.
-Add features.
-Offer convenience.
-Improve efficiency of production.
Benefits of added value?
-Creates customer loyalty.
-Can increase profit margins.
-Spread risks.
-Higher prices can be charged.
-Job security for employees.
-Higher dividends and better image for shareholders.
-More convenient and better quality for customers.
Limitations of added value?
-No guarantees that adding value will be able to be covered with higher prices.
-Higher prices need to cover higher costs could reduce demand.
-Difficult in competitive markets because can choose cheaper alternatives.
What is job production?
-Making products one at a time, usually to the buyer’s specification.
-Wedding cakes, buildings, suits.
-Made by highly skilled workers.
Benefits of job production?
-High quality products so a high price can be charged as they have lots of added value.
-Workers are motivated.
-Can be differentiated.
Drawbacks of job production?
- Unit costs are higher than using flow production.
[Labour intensive processes, so cannot use machinery as much] - Requires skilled employees who may demand higher wages and/or ongoing training
- Takes longer to produce.
What is batch production?
-Making a limited number of identical products in batches.
-At each of production, the work is completed for all the products before moving on to the next stage.
-Semi skilled workers.
-Bakeries and furniture.
Benefits of batch production?
-Lower cost per unit and higher output than job.
-Can access economies of scale.
-More motivating than flow.
-Can still differentiate.
Drawbacks of batch production?
-Time is lost when resetting machines/switching methods.
-May not be able to deal with large numbers.
-Products are not as bespoke.
What is flow production?
-Involves identical products being made on an assembly line. The product is made in stages, with parts being added as it moves along the assembly line.
-Production is broken down into simple tasks so machinery/robots can be utilised.
Benefits of flow production?
- Businesses can produce on a larger scale
- Uses less labour than job production
- Consistent quality standard, because of division of labour.
- Lower unit costs than job production
- Economies of scale
Drawbacks of flow production?
- Production can be inflexible due to use of machinery (little variation of products)
- Jobs are repetitive for staff and can lower motivation
- Initial set up and purchase costs can be high
- Can’t differentiate products.
What is productivity?
the efficiency with which a production or service activity converts inputs into outputs, expressed as ratios
What is labour productivtiy?
output/number of workers
what is capital productivity?
output/capital employed.
What is overall productivity?
output/number of employees and machines.
What is revenue contribution of machines/workers?
Sales revenue/number of workers ormachines.
What affects productivity?
-amount of capital equipment accessible
-amount of eduction/training of employees
-motivation.
-supply issues.
-experienced staff leaving.
How can productivity be improved?
-training.
-Improve motivation.
-Invest in new technology/machines.
-Retention schemes.
-Better quality raw materials so less are wasted.
What are the advantages of high productivity?
-Increased economies of scale and competitiveness.
-Spreads fixed costs over a higher output.
-Lower cost per unit.
-Higher performance bonuses.
-Higher dividends for shareholders.
What is capital utilisation?
The percentage of total capacity that is actually being achieved by the business.
How to calculate capital utilisation?
(current output/full capacity) x100
Why can businesses be below full capacity?
Lower demand, inefficiency, increases capacity has not been matched with demand.
What are the problems of spare capacity?
-Demotivaiton of staff because no overtime available or the threat of redundancy.
-Increased costs to a business (redundancy payments).
-Reduced profits.
-Lack of return on investment capital.
How can businesses deal with increased demands?
-Increase workforce hours.
-Subcontract production.
-Purchase new equipment.
How does increasing demand solve under utilisation?
-Advertising, product development and innovation.
-Increased production means utilisation rises.
-However, demand will not overcome inefficiency, and some products may not have inelastic demand.
How can subcontracting solve under utilisation?
-Someone else produces goods for you.
-Reduces the capital investment required so there is is reduction in risk.
-Can lead to difficulty in quality control and higher prices, so customers may be dissatisfied.
How does rationalisation solve under utilisation?
-Concentrating on core products.
-Most efficient at producing these and also reduces the overall full capacity, so percentage is likely to increase.
-Customers can be lost.
How can use of assets solve under utilisation?
-Retailers can sublet to other businesses.
-Manufacturers can look into new product ranges or be subcontractors for other businesses.
What are the problems with working at full capacity?
-Stressed and overwokred workforce.
-Negative effect on quality in production is rushed or if there is no time to quality check.
-Miss out on sales as you cannot deal with a sudden increase in demand.
-More machine break down/failures.St
Strengths of using capital utilisation?
-Indicates how effectively resources are used.
-As utilisation rises, cost per unit falls.
Weaknesses of using capacity utilsation?
-Higher utilisation, more negative effects on quality.
-Pressures on workforce.
What new technology is used in operations?
CAD, CAM, computer modelling, robotics, I.T.
CAD:
-Computer aided design.
-The use of computers to design new products or altering existing designs.
-Quicker design process and less likely to make mistakes.
-The output is a file that you can send to clients or straight to CAM.
-Cheap but need to have the skills to use.
CAM:
-Computer aided manufacturing.
-Computer programmed to operate robotics and manufacture products using CAD output.
-More efficient and can work 24/7, and there is more consistent quality.
-More expensive and needs specialist workers.
Computer modelling:
A computer program that attempts to simulate an abstract model of a particular system.
-Can answer many what if scenarios.
-Will improve the customer experience because more scenarios are considered.
I.T:
-Pre-formatted letters, spreadsheets and cash flow modelling helps to make each department more efficient and save time.
Advantages of new technology?
-Computers have high precision so better quality, therefore better for customers.
-Faster innovation, CAD is quicker with designing.
-Less dependant on labour.
-Increased productivity, which could lower prices for customers.
-Less waste.
-Employees have opportunities to learn new skills.
-Increased skill and capacity for technology is attractive to other businesses to locate in the UK, so the government benefits.
Disadvantages of new technology?
-Very large upfront costs.
-Workers may be made redundant.
-Managers have to train the workers to use the technology.
What is lean production?
An approach to management that focuses on cutting out waste whilst ensuring quality, productivity and reducing costs.
What is considered as waste?
-Raw material lying around.
-Work in progress products.
-The finished product waiting to be delivered.
-Skills and knowledge not being used.
What are the lean production practises?
Just in time, kaizen, cell production, time based management.
Benefits of lean production?
-Decrease in waste saves cost.
-Workers are encouraged to be involved which increases motivation.
Drawbacks of lean production?
-Businesses will struggle to meet demand if supplies are not delivered on time.
-May not be able to access economies of scale.
-Workers may be reluctant to change.W
What is just in time production?
type of lean production system that brings together all materials at the precise time they are required at each production stage. Products are only made when there is demand for the products.
Just in time: management understanding?
-Managers must walk the line and understand the whole process used to complete the product.
