operation management - a level business p1

EDUQAS EXAM BOARD

explain what is meant by operation management

operation management : managing the process of transforming inputs(raw materials , labour, technology and capital) into outputs(goods/services) to satisfy customers and achieve business objectives

operations differ according to : size/nature of a business, product / service, production method technology and workforce skills

define added value and explains ways businesses can increase it and the importance of it

Added value: is the difference between the cost of producing a product and the price the business sells it for.(Formula: Added value = Selling price − Cost of inputs)

A business can increase added value by : increasing price , reduce input cost, improve production process and improved customer service

importance : higher added value = potentially higher profit margins, differentiation and competitiveness(importance to a business), it can also provide better products/services (customers) , greater job security (employees), higher profits (shareholders),

Explain the different methods of production including job, batch and flow and evaluate them

1. job production : one at a time , usually customised.

advantages of job production: highly customised, high quality and premium prices

disadvantages of job production: expensive , labour intensive , slow

2. batch production : products made in batches / groups then machinery is changed for another batch

advantages of batch production : greater variety , lower unit cost than job

disadvantages of batch production: downtime between batches , storage required and less flexible

3. flow production : continuous production of standardised products using a production line

advantages of flow production : very high output , low unit cost , consistent quality

disadvantages of flow production : high capital cost , repetitive work , inflexible , breakdowns can stop entire lines

Explain what is meant by productivity and ways in which productivity can be increased and Evaluate the importance and impact of productivity

productivity : efficiency with which inputs are converted into outputs (formula : labour productivity = output divided by number of employees )

productivity can be increased through : training , employee motivation, specialisation , lean production

benefits : high productivity means lower unit cost which leads to greater competitiveness / profit which could lower prices

drawbacks : high cost in training / technology , redundancy , employee stress , quality can fall

Explain the concept of capacity utilisation and Evaluate the concept of capacity utilisation for a business and its stakeholders

capacity utilisation : % of maximum possible output currently being produced (formula : actual output divided by maximum possible output x 100)

high capacity utilisation

Advantage: fixed cost spreads over more output , lower average costs , assets used efficiently

disadvantage: less spare capacity , difficult to respond to demand increase , quality may fall

low capacity utilisation:

advantages : spare capacity , easier to respond to demand changes , flexibility

disadvantages: resources underused , higher unit costs , possible redundancies

Explain how new technology can be used by businesses, including the use of information technology, CAD, CAM and robotics

information technology(it): computers/software which are used to collect , process, store and communicate information . used in : stock control, communication, accounts, customer data and online sales

CAD(computer-aided design): computer software used to design/test for products digitally

advantages of CAD: faster design , easier modifications, accurate and can reduce development costs

CAM(computer - aided manufacturing): computer controlled machinery used to manufacture products

advantages of CAM: speed, consistency, precision; lower labour costs

robotics: programmable machines performing physical production tasks

advantages of robotics: 24/7 operation; consistent quality; speed; precision; dangerous tasks can be automated

disadvantages of robotics: expensive, maintenance, redundancies, skills required

Evaluate the impact of new technology on the various stakeholders of a business

business: increased productivity, quality and competitiveness

employees: safer/ new skilled jobs, possible redundancies/ de-skilling

customers: better quality and greater choice

shareholders: higher profits (maybe) but investment risk

society/government: productivity/tax revenue may rise and unemployment may rise

OVERALL DEPENDS ON EXPECTED DEMAND , COST OF INVESTMENT , WORKFORCE SKILLS AND SPEED OF TECHNOLOGICAL CHANGE

Explain what is meant by lean production and Explain the range of lean production practices that are used to reduce waste and improve productivity

Lean production = an approach to production that aims to minimise waste and maximise efficiency/productivity, while maintaining the quality and value customers expect.

• Kaizen (continuous improvement): Employees at all levels make small, continuous improvements to processes → identifies inefficiencies → reduces waste, improves productivity/quality and can motivate employees. However, constant pressure to improve can increase stress/resistance.

• Just-in-time (JIT): Materials/components arrive only when needed → ↓ inventory/storage costs, ↓ waste and ↓ capital tied up in stock → potentially improves cash flow. However, requires reliable suppliers and accurate demand forecasts; disruption can stop production and cause lost sales. Most suitable when demand and supply are reliable.

• Cell production: Workers and equipment are organised into self-contained production cells → ↓ movement/waiting time, ↑ teamwork and communication, and workers can become multi-skilled → greater flexibility/productivity. However, training and restructuring can be costly.

• Time-based management: Reduces waiting, set-up/changeover, production, movement and delivery times → faster production and delivery → ↑ productivity and customer satisfaction → potentially greater competitiveness.

Evaluate the importance and impact of lean production for businesses and their stakeholders

Business

Potential benefits:

• ↑ productivity

• ↓ waste

• ↓ unit costs

• ↑ competitiveness/profit margins

• ↑ quality

Potential drawbacks:

• Training/reorganisation costs.

• JIT makes the business vulnerable to supply disruptions.

• Continuous efficiency pressures may reduce employee morale.

• Some lean methods require significant changes to organisational culture.

Employees

Positive: greater involvement, multi-skilling, teamwork and potentially higher motivation.

Negative: greater work pressure, tighter performance expectations and resistance to organisational change.

Customers

Positive: potentially lower prices, better quality, faster delivery and greater reliability.

Negative: JIT-related shortages or production disruption can lead to delays or unavailable products.

Suppliers

Positive: potentially stronger long-term relationships and more predictable orders.

Negative: JIT may place pressure on suppliers to deliver frequently, quickly and reliably, increasing their costs.

Shareholders

Successful lean production can increase profitability and competitiveness, potentially increasing returns to shareholders. However, disruption or implementation costs could reduce short-term profits.

Environment

Less material, energy, inventory and unnecessary movement can reduce waste and environmental impact. However, frequent JIT deliveries can increase transport emissions

define quality and the importance of it

Quality = the extent to which a product/service meets or exceeds customer expectations and specifications.

Importance of quality

High quality →

• ↑ customer satisfaction → ↑ repeat purchases/loyalty

• ↓ complaints, returns and warranty costs

• ↑ reputation/brand image → competitive advantage

• Potentially ↑ sales, market share and profit

• ↓ waste/rework → ↑ productivity and lower unit costs

Poor quality → complaints/returns → damaged reputation → lost customers/sales → higher costs → lower profit.

Explain the difference between quality control and quality assurance

Quality control (QC)	Quality assurance (QA)
Checks the finished product/output for faults.	Prevents faults occurring by controlling the production process.
Usually involves inspection/testing.	Involves systems, procedures and standards throughout production.
Reactive — identifies problems after/while they occur.	Proactive — aims to prevent problems.
Defective products may need to be rejected/reworked.	Reduces the likelihood of defects occurring in the first place.

Explain the concept of total quality management (TQM) and the ways that it can be achieved including quality chains, empowerment, monitoring, teamwork, zero defects, quality circles and benchmarking

TQM = a whole-business approach to continuous improvement, where all employees are responsible for improving quality and meeting customer needs.

Methods of achieving TQM

• Quality chains: Every stage/employee is responsible for passing quality output to the next stage; poor quality at one stage affects the whole chain.

• Empowerment: Employees are given authority/responsibility to identify and solve quality problems → quicker decisions + greater motivation.

• Monitoring: Continuously measuring/checking processes and performance → problems identified early → corrective action.

• Teamwork: Employees work together to identify and solve quality problems → better communication and ideas.

• Zero defects: Aim to produce no defective products, rather than accepting a predetermined level of defects → reduces waste, returns and rework.

• Quality circles: Small groups of employees meet regularly to identify and solve quality problems → uses employee knowledge and encourages continuous improvement.

• Benchmarking: Comparing performance/processes against competitors or organisations considered best practice → identifies gaps and areas for improvement.

Evaluate the importance of quality for a business and its stakeholders

• Business/shareholders: Higher quality can ↑ sales, reputation and profit; however, quality systems, training and monitoring create costs.

• Customers: Better reliability, safety and consistency → ↑ satisfaction and loyalty. Poor quality causes complaints and loss of trust.

• Employees: Empowerment/teamwork can ↑ motivation and involvement, but increased responsibility and monitoring may create pressure.

• Suppliers: Quality standards may improve supplier performance but can increase their costs and requirements.

• Environment: Less defective output/rework → less material and energy waste.

Explain the importance of purchasing and working with suppliers

Purchasing = obtaining the materials, components, goods or services a business needs for production/operations.

Effective purchasing is important because it can:

• Ensure reliable supply → production can continue.

• Obtain appropriate quality → fewer defects/returns.

• Negotiate lower prices → ↓ unit costs → ↑ profit.

• Build strong supplier relationships → better reliability, flexibility and communication.

• Reduce delivery times → supports JIT and customer service.

• Improve cash flow through favourable payment terms.

Explain what is meant by stock control and Understand the importance of controlling stock

Stock = materials/components, work-in-progress and finished goods held by a business.

Stock control = managing stock levels to ensure the business has enough stock to meet demand without holding excessive amounts.

Why control stock?

Effective stock control can:

• Prevent stockouts → avoid production stoppages/lost sales.

• ↓ storage/insurance/security costs.

• ↓ risk of stock becoming obsolete, damaged or perishable.

• Reduce capital tied up in stock → improve cash flow.

• Support efficient production/customer service.

Explain methods of stock control including traditional stock control methods, just-in-time and computerised stock control

Traditional stock control: Stock is monitored manually, often using stock records/cards and regular physical checks.

Pros: simple, relatively cheap.
Cons: time-consuming, human error, less accurate/real-time.

Just-in-time (JIT): Stock arrives only when needed for production/sales.

→ ↓ storage costs + ↓ capital tied up + ↓ obsolete stock.

Risk: supplier failure/demand increases → stockout → production stoppage/lost sales.

Computerised stock control: Computer systems automatically record stock levels and sales, often using barcodes/RFID, and can trigger reorders.

→ accurate, real-time information + less human error + faster reordering.

Limitation: software/equipment costs and dependence on accurate data/technology

Interpret stock control diagrams and explain the main components including re-order level, lead time, buffer stock and minimum stock level

Know these components:

• Lead time: time between placing an order and receiving the stock.

• Re-order level: stock level at which a new order is placed so delivery arrives before stock runs out.

• Buffer stock: minimum reserve stock held to protect against unexpected demand/supply problems.

• Minimum stock level: lowest stock level the business aims to reach; usually the buffer stock level.

Diagram logic

Stock level ↓ as stock is used → reaches re-order level → order placed → stock continues falling during lead time → delivery arrives → stock rises.

If demand/supply is unexpectedly disrupted, buffer stock prevents stock reaching zero.

Key formula: Re-order level = maximum usage × maximum lead time

Evaluate the importance and impact on businesses and their stakeholders of holding too much or too little stock

Too much stock	Too little stock
↑ storage/insurance/security costs	Risk of stockouts
Capital tied up → ↓ liquidity/cash flow	Production may stop
Risk of damage/obsolescence	Lost sales/customers
Particularly costly for perishable goods	Emergency ordering may ↑ costs
Greater ability to meet unexpected demand	Lower storage costs + less capital tied up

Stakeholder impact

• Business/shareholders: Too much → higher costs and tied-up capital; too little → lost sales and potentially damaged reputation/profits.

• Customers: Too much generally improves availability; too little can cause delays/stockouts.

• Employees: Too little can cause production stoppages/uncertainty; excessive stock may increase operational workload.

• Suppliers: Too little can result in urgent orders; effective stock management can create more predictable purchasing.

define innovation, research and development

• Innovation: Successful introduction of a new or significantly improved product, service or process.

• Research: Gathering new knowledge/information to generate ideas or solve problems.

• Development: Turning research/ideas into a usable, tested product/process.

• R&D: Research + development undertaken to create/improve products or processes.

Explain the process of product design and development

1. Generate ideas – market research, customer feedback, employees, competitors/technology.

2. Screen ideas – assess demand, feasibility, costs, resources and profitability.

3. Design/develop concept – features, materials, function and target market.

4. Prototype & test – test quality, safety, performance and customer response.

5. Modify – use feedback to improve the product.

6. Launch – production, marketing and distribution.

7. Review – monitor performance/customer feedback and improve further.

Evaluate the costs and benefits of innovation, research and development for a business and its stakeholders

Costs of innovation/R&D: High R&D, labour, equipment and testing costs, Opportunity cost of using resources elsewhere, Long development time → delayed returns, Risk of failure → expenditure may not be recovered.

Benefits: New/improved products → ↑ sales/market share., Differentiation → competitive advantage, Improved processes → ↑ productivity/quality and potentially ↓ costs, ↑ brand image/customer loyalty.

Stakeholders

• Shareholders/business: Potential ↑ growth/profit, but high costs and risk.

• Customers: More choice, better quality/features and potentially lower prices.

• Employees: New skills/jobs, but retraining or job losses from automation.

• Suppliers: Potential ↑ orders, but changing technology may make existing suppliers unnecessary.

• Society/government: Innovation can create jobs/economic growth but may create environmental/social issues.

Explain what is meant by economies of scale

Economies of scale = the fall in average cost per unit as output increases.

Why? Fixed costs are spread over more units and/or the business gains efficiencies from operating on a larger scale.

Key formula:

Average cost = Total cost ÷ Output

Explain the different types of internal economies of scale and their benefits

Type	Meaning → benefit
Purchasing/bulk-buying	Larger orders → greater bargaining power/quantity discounts → ↓ input cost per unit.
Technical	Large-scale/specialised machinery → ↑ productivity → ↓ average cost.
Managerial	Larger firms can employ specialist managers → greater expertise/productivity → ↓ average cost.
Financial	Larger, established firms may access finance more easily/cheaply → ↓ cost of borrowing.
Marketing	Advertising costs spread over greater output → ↓ marketing cost per unit.
Risk-bearing	Large firms can diversify products/markets → spread risk → greater stability.

explain what is meant by External economies of scale and their benefits

External economies of scale = cost advantages received because the industry/area in which a business operates grows, rather than because the individual business grows.

Examples:

• Skilled labour pool develops → easier/cheaper recruitment.

• Infrastructure improves → lower transport/communication costs.

• Specialist suppliers locate nearby → easier/cheaper sourcing.

• Industry knowledge/training increases → ↑ productivity.

Important: These benefit multiple businesses in the industry, not just one firm.

Explain reasons for internal diseconomies of scale and the problems caused by internal diseconomies of scale

Diseconomies of scale occur when a business becomes too large, causing average cost per unit to rise.

Causes

• Communication problems → information takes longer to reach employees → mistakes/delays.

• Poor coordination → difficult to manage large operations.

• Bureaucracy → more layers of management → slower decision-making.

• Employee motivation falls → workers feel less valued/less connected → ↓ productivity.

• Managerial difficulties → harder to monitor/control a large workforce.

Problems

↑ average costs → ↓ profit margins or higher prices → ↓ competitiveness → potentially ↓ sales/market share/profit.

Explain the survival of small firms

Small firms can survive despite lacking many economies of scale because they can:

• Differentiate products through quality, uniqueness or personal service.

• Serve niche markets that large firms cannot profitably target.

• Be flexible → respond quickly to changing customer needs.

• Provide personalised/customer-focused service.

• Have lower management/communication costs.

• Build strong customer relationships and loyalty.

• Face lower overall demand requirements where the market is small.

Evaluate the impact of economies and diseconomies of scale on a business and its stakeholders

Economies of scale

• Business/shareholders: ↓ average costs → ↑ competitiveness/profit potential.

• Customers: Potentially ↓ prices and ↑ choice.

• Employees: Growth may create jobs/career opportunities, but greater scale can reduce personal involvement.

• Suppliers: Larger orders can increase sales but firms may use bargaining power to force lower prices.

• Society: Lower prices can increase consumer welfare, but large firms may gain significant market power.

Diseconomies of scale

• Business/shareholders: ↑ average costs → ↓ profitability/competitiveness.

• Customers: Potential ↑ prices or ↓ quality/service.

• Employees: Poor communication, bureaucracy and reduced motivation.

• Suppliers: Large firms may have greater bargaining power, potentially squeezing supplier margins.
