3. Marketing (AS)

3.1 Nature of Marketing & Demand‑Supply Interaction

• Marketing is the process of creating, communicating and delivering value to satisfy customer needs.
• Demand‑supply diagram – equilibrium price, shifts caused by changes in consumer preferences or production costs.
• Market share = (Company’s sales ÷ Total market sales) × 100 %.

3.2 Market Research & Analysis

• Primary data: surveys, interviews, focus groups – fresh but costly.
• Secondary data: published reports, statistics – cheaper, may be outdated.
• Quantitative (structured, numerical) vs qualitative (opinions, attitudes).
• Sampling techniques – random, stratified, systematic, convenience; each has advantages and limitations.

3.3 The Marketing Mix (4 Ps)

Product	Price	Place	Promotion
Features, branding, life‑cycle, packaging, warranty.	Pricing objectives, cost‑plus, competition‑based, psychological pricing, discounts.	Channels (direct, indirect), logistics, retail formats, e‑commerce.	Advertising, sales promotion, public relations, personal selling, digital marketing.

3.4 STP – Segmentation, Targeting & Positioning

• Segmentation bases – demographic, geographic, psychographic, behavioural.
• Targeting strategies – undifferentiated, differentiated, concentrated, micromarketing.

• Promotion mix – integrated marketing communications, social media, sponsorship.
• Place decisions – intensive, selective, exclusive distribution; channel conflict management.
• Customer Relationship Management (CRM) – data‑driven approach to retain and upsell customers.

4. Operations Management (AS)

4.1 Production Methods & Factors of Production

• Job production – custom, high flexibility, high cost per unit.
• Batch production – moderate flexibility, set‑up costs between job and flow.
• Flow (mass) production – low flexibility, high volume, low unit cost.
• Cellular production – groups of similar processes, reduces movement.
• Lean production – waste elimination, continuous improvement.
• Capital‑intensive vs labour‑intensive – impact on skill requirements and cost structure.

4.2 Productivity & Efficiency

Labour productivity = Output (units) ÷ Labour hours.

Capacity utilisation = (Actual output ÷ Maximum possible output) × 100 %.

4.3 Location & Scale of Operations

• Location factors – market access, labour costs, transport, utilities, government incentives, agglomeration economies.
• Economies of scale – internal (technical, managerial) and external (cluster) – lower average cost as output rises.
• Dis‑economies of scale – bureaucracy, coordination problems, reduced flexibility.

4.4 Inventory Management

• Inventory types – raw materials, work‑in‑process (WIP), finished goods.
• Economic Order Quantity (EOQ):
  EOQ = √[ (2DS) / H ]
  where D = annual demand, S = ordering cost per order, H = holding cost per unit per year.
• Re‑order point (ROP): ROP = (Average daily usage × Lead time) + Safety stock.
• Just‑In‑Time (JIT) – minimal stock, reduces holding costs but increases vulnerability to supply disruptions.
• Just‑In‑Case (JIC) – higher safety stock for risk‑averse environments.

4.5 Outsourcing & Technology

• Outsourcing – contract external firms for non‑core activities (e.g., logistics, IT).
• Benefits: cost reduction, focus on core competence, access to specialist skills.
• Risks: loss of control, quality issues, dependency on supplier.
• Key technologies – ERP (integrates finance, HR, production), CAD/CAM, robotics, AI‑driven forecasting.

4.6 Quality Management – Impact of QC Methods on Business

Definitions

• Quality Control (QC): Operational techniques (inspection, testing) to ensure products/services meet set standards.
• Quality Assurance (QA): Systematic processes that give confidence that quality requirements will be fulfilled.
• Total Quality Management (TQM): Organisation‑wide culture of continuous improvement involving all employees.

Common QC Methods

Method	Key Features	Typical Use	Impact on Business
Inspection	Visual/functional checks; 100 % or sampling	Finished‑goods testing, low‑volume bespoke items	Reduces defective output; increases labour cost and possible waste if re‑work required
Statistical Process Control (SPC)	Control charts (X‑bar, R, p‑charts) monitor process variation	Continuous production lines	Early detection of variation → lower scrap, higher consistency, improved customer satisfaction
Six Sigma	DMAIC cycle (Define‑Measure‑Analyse‑Improve‑Control); aims for ≤3.4 defects per million	Complex processes, high‑value products	Significant cost savings, stronger brand reputation, competitive advantage
ISO 9001 Certification	Documented QA system, internal audits, continual improvement	Companies seeking market access, especially internationally	Improved stakeholder confidence, easier entry into new markets, potential price premium
Benchmarking	Comparing processes/performance with best‑in‑class firms	Strategic improvement projects	Identifies gaps, drives innovation, can reduce costs and increase market share

Overall Business Impact

• Cost reduction: Fewer defects → lower re‑work, scrap, warranty claims.
• Customer satisfaction & loyalty: Consistent quality builds brand trust, encouraging repeat purchases.
• Reputation & market positioning: Quality certifications can be used as marketing tools.
• Operational efficiency: QC data feeds into process improvement (lean, Six Sigma).
• Compliance: Meets legal and industry standards, avoiding fines and product recalls.

5. Finance & Accounting (AS)

5.1 Need for Finance & Sources

Finance is required for start‑up, working capital, expansion, research & development, and to cope with unexpected events.

Source	Nature	Cost	Control
Bank loan	Debt	Interest payable	High (lender covenants)
Equity (share issue)	Equity	Dividends & dilution	Low (no fixed repayments)
Trade credit	Short‑term debt	Usually none (if paid within terms)	Medium
Retained earnings	Internal	Opportunity cost of not distributing profit	Full
Leasing	Finance	Lease payments + interest	Medium
Venture capital	Equity	High expected return, possible control share	Low (VC involvement)

5.2 Working Capital & Cash Flow

• Working capital: Current assets – Current liabilities.
• Cash‑flow forecast – projected cash inflows (sales, receivables, loans) vs outflows (payables, wages, overheads).
• Cash conversion cycle = Inventory days + Receivables days – Payables days.

5.3 Costing & Break‑Even Analysis

• Fixed costs (FC) – do not vary with output (rent, salaries).
• Variable costs (VC) – vary with output (materials, direct labour).
• Contribution per unit = Selling price – Variable cost per unit.
• Break‑even volume = FC ÷ Contribution per unit.
• Example: FC £120 000, SP £30, VC £12 → Contribution £18 → BE = 120 000 ÷ 18 = 6 667 units.

5.4 Budgeting & Variance Analysis

• Types of budgets: Static (fixed), Flexible (adjusts for activity level), Zero‑based (every expense justified).
• Variance = Actual – Budgeted.
  • Favourable variance – results better than budget.
  • Unfavourable variance – results worse than budget.
• Common variances – sales volume, material price, labour efficiency, overhead absorption.

6. Business & Its Environment (A‑Level)

• Porter’s Five Forces: Quantitative scoring (1‑5) for each force to assess industry attractiveness.
• Ansoff Matrix: Market penetration, market development, product development, diversification – assess risk.
• BCG Growth‑Share Matrix: Classify SBUs as Stars, Cash Cows, Question Marks, Dogs; decide on investment or divestment.
• Value Chain Analysis: Identify primary (inbound logistics, operations, outbound logistics, marketing & sales, service) and support activities (firm infrastructure, HRM, technology, procurement) to find cost advantage or differentiation points.

7. Human Resource Management (A‑Level)

7.1 Advanced Organisational Structures

• Matrix – dual reporting (functional & product); benefits for project focus, risk of role conflict.
• Network/Virtual – core activities retained, non‑core outsourced; enables rapid scaling, reliance on ICT.
