3.3.3 — Decision-Making Techniques

Key idea

Quantitative techniques like decision trees and investment appraisal reduce risk, but they rely on estimated data — qualitative judgement is always needed alongside the numbers.

  • Decision trees — map out choices with probabilities and expected values to compare options.
  • Investment appraisal — payback, ARR and NPV each give a different perspective on a project.

Unit overview

What you need to know for WBS13

Objectives shape every decision
Every strategy question requires you to link back to business objectives. Short-term vs long-term, stakeholder conflicts and the mission statement all matter.
Quantitative tools have limits
Decision trees, CPA and investment appraisal give useful numbers, but examiners reward you for evaluating their limitations — estimated data, external changes, qualitative factors.
Competitiveness is relative
A business is only competitive compared to its rivals. Use the financial statements, ratio analysis and human resource measures such as labour productivity and labour turnover to analyse competitive position — and always consider the market context.
Change depends on key factors
Whether change succeeds depends on organisational culture, the size of the organisation, the time and speed of change, how resistance is managed and transformative leadership. Contingency planning identifies key risks through risk assessment, then plans for business continuity and succession.
