Operations Flashcards
Explain added value
The difference between what a business spends to produce its goods or service, and the price customers are willing to pay
How do you calculate added value
The selling price - the cost of bought in materials and components
Explain what’s meant by innovation
Altering an already existing product
Explain what’s meant by research
Work done to see how you could improve a product
Explain what’s meant by development
Physically improving the product from the research you have conducted
Explain the reasons for innovation, research and development within a business and industry
Improve productivity
Increase competitiveness
Improve brand recognition
Increase turnover
Improve profitability
Changing external factors
Explain product innovation
Developing existing products to differentiate it from their competitors
Explain process innovation
Finding a new or better method of production to increase: efficiency, productivity, reduce costs +waste and to improve quality
Evaluate the disadvantages of innovation
Time consuming
Initial costs
Staff motivation
Evaluate the advantages of innovation
Improved productivity
Reduced costs
Increased competitiveness
Improved brand recognition
Increased turnover and profitability
Explain job production
Production items that meet specific needs of customers
Explain batch production
May similar items are produced together
Explain flow production
Continuous movement of items through production processes (when one task finishes the next one starts immediately)
Explain cell production
Workers split into teams to work on a part of the production process
State advantages of job production
Meets customers needs
High quality
Higher job satisfaction
More flexibility
state disadvantages of job production
No economies of scale
Higher costs
Requires skilled labour
Difficult costing
State advantages of batch production
Reduces unit costs
Can still address customer needs
Faster than job production
Some economies of scale
Some flexibility
State disadvantages of batch production
Time can be lost switching batches
Need to keep stock of raw materials
Can be de-motivating
Money is tied up in storage
State advantages of flow production
Continuous
Economies of scale lowers the cost of production
Division of labour and specialisation
State disadvantages of flow production
Difficult to alter the production o=process
Employee boredom
High set up costs
Can’t address customer needs
State advantages of cell production
Workers become multi-skilled and adaptable
Greater workers motivation
Can lead to efficiency
Quality improvements
State disadvantages of cell production
May not allow firms to use their machinery as intensively, meaning output will be lower
Greater investments required in new management and control process
May be rivalry between different cells and conflict may arise
Explain specialisation
Where workers perform specific tasks
Explain division of labour
The allocation of workers into specific tasks, intended to increase productivity
Explain the reasons for the introduction of specialisation and division of labour into a business
It’s introduced for the intention that worker productivity and efficiency will increase therefore lowering business costs. This creates a larger profit for them
Explain the advantages of division of labour
Workers become more efficient
Output increases whilst lowering business costs
Improves the profit margin
Explain the disadvantages of division of labour
Tasks may become repetitive so workers become de-motivated and less efficient
If talks are small and repetitive, automation may take over resulting in redundancies
Explain project management
The act of planning, organising and managing a project in order to achieve a predefined outcome or goal
Explain why businesses use project management
It helps every part of the business run more efficiently and effectively
Explain what a Gantt chart is
Graphical representation of the order and duration of tasks within a project
Explain what CPA is
A project management technique which shows how to complete tasks in the shortest possible time
Explain what PERT analysis is
Used to calculate the amount of time it takes to realistically finish
Explain the advantages of PERT analysis
More realistic given pessimistic views
A simple formula to apply
A lot of data can be visually represented
Explain the disadvantage of PERT analysis
It can be difficult to judge
Explain the advantages of a Gantt chart
Allows a visual representation
Easy to monitor
Shows time and resource allocation
Explain the disadvantages of a Gantt chart
Doesn’t show the critical activities
Can’t see EST and LFT
Can’t calculate float times
Explain the advantages of CPA
Helps reduce the risk and cost of complex projects
Encourages careful assessment
Better allocation of resources
Provides managers with a useful overview of the project
Allows resources to be delivered just in time (JIT)
Explain the disadvantages of CPA
Reliability is largely based on accurate estimates
Doesn’t guarantee success of the project
Resources may not be as flexible as the management hope
