HL Extension: Business Strategy and Decision Making

This Higher Level extension pulls the course together through strategic decision-making and the HL Business Management Toolkit: SWOT and STEEPLE, the Ansoff matrix, decision trees, force field analysis, critical path analysis and Hofstede's cultural dimensions โ€” all integrated with the four concepts.

Every screen here is HL only. The calculations (expected values, net driving force and critical-path float) are all recomputed.

Work through each screen, answer the questions as you go and collect โญ stars. Press Start when you are ready.

Strategy vs tactics

Making strategic decisions

Strategy is the long-term plan to achieve the vision and objectives; tactics are short-term actions that carry it out. Strategic decisions are large, long-term, hard to reverse and cut across every function. The Business Management Toolkit supplies tools to analyse a situation and choose between options, always weighing change, creativity, ethics and sustainability.

  • SWOT โ€” internal strengths and weaknesses; external opportunities and threats.
  • STEEPLE โ€” the external environment: Social, Technological, Economic, Environmental, Political, Legal and Ethical factors.
Quick check

Strategy or tactic?

?A supermarket decides to enter grocery delivery across the whole country over the next five years, changing its logistics and stores. This decision is best described as:
Ansoff matrix

Four growth directions (HL toolkit)

The Ansoff matrix maps growth by product (existing/new) and market (existing/new), from lowest to highest risk:

  • Market penetration โ€” existing products, existing markets (lowest risk).
  • Market development โ€” existing products, new markets.
  • Product development โ€” new products, existing markets.
  • Diversification โ€” new products, new markets (highest risk).

Decision trees

Weighing options by expected value (HL toolkit)

A decision tree maps choices (squares) and chance events (circles) with probabilities and payoffs. The expected value (EV) of a chance node is the sum of each outcome's probability times its payoff. The net expected value subtracts the cost of the decision. Choose the option with the highest net EV โ€” but remember probabilities are estimates.

expected value = ฮฃ (probability ร— payoff)net EV = expected value โˆ’ cost of the option
Calculate

Expected value

1An option has a 0.6 chance of a 500,000 dollar payoff and a 0.4 chance of a 100,000 dollar payoff. Calculate its expected value.
$
Hint: EV = (0.6 ร— 500,000) + (0.4 ร— 100,000) = 300,000 + 40,000.
Calculate

Net expected value

2Setting up that option costs 50,000 dollars. Using the expected value you just found, calculate the net expected value.
$
Hint: net EV = expected value โˆ’ cost = 340,000 โˆ’ 50,000.

Choosing with a decision tree

?Option A has a net expected value of 290,000 dollars; Option B has a net expected value of 220,000 dollars. On expected-value grounds alone, the firm should:
Force field analysis

Driving vs restraining forces (HL only)

Force field analysis (Lewin) evaluates a change by scoring the driving forces pushing for it against the restraining forces resisting it. If the net score is positive the change is likely to succeed; managers then strengthen drivers and weaken resistors.

net force = total driving โˆ’ total restraininga positive result favours the change
Calculate

Net driving force

3A proposed change scores total driving forces of 15 and total restraining forces of 8. Calculate the net force.
points
Hint: net force = total driving โˆ’ total restraining = 15 โˆ’ 8.
Critical path analysis

Networks, floats and the critical path (HL only)

Critical path analysis (CPA) schedules a project as a network of activities with durations, earliest start times (EST) and latest finish times (LFT). The critical path is the longest sequence, with zero float โ€” any delay there delays the whole project. Float (slack) is spare time on non-critical activities.

float = LFT โˆ’ duration โˆ’ ESTcritical activities have a float of zero
Calculate

Activity float

4An activity has an earliest start time (EST) of 5, a duration of 4 days and a latest finish time (LFT) of 13. Calculate its float.
days
Hint: float = LFT โˆ’ duration โˆ’ EST = 13 โˆ’ 4 โˆ’ 5.
Hofstede's cultural dimensions

Managing across cultures (HL only)

Hofstede compares national cultures on dimensions such as power distance, individualism vs collectivism, masculinity vs femininity, uncertainty avoidance, long-term orientation and indulgence vs restraint. Multinationals use it to adapt leadership, motivation and marketing to local expectations โ€” and to anticipate culture clashes.

Integrating the concepts

Balanced strategic recommendations

A strong HL answer combines tools with the four concepts. A Gantt chart and CPA plan the change; decision trees and force-field analysis test creativity against risk; and recommendations weigh ethics and sustainability, not just profit. Always evaluate: quantitative tools rest on estimates, so judgement and context still decide.

Recap

The big ideas to know

Strategy: long-term, cross-functional, hard to reverse; analysed with SWOT and STEEPLE.

Ansoff: penetration, market development, product development, diversification (rising risk).

Decision trees: EV = ฮฃ(probability ร— payoff); choose the highest net EV.

Force field: net force = driving โˆ’ restraining; positive favours change.

Critical path: float = LFT โˆ’ duration โˆ’ EST; the critical path has zero float.

Hofstede: cultural dimensions guide managing multinationals; integrate the four concepts.
