Managers, leadership and decision making

Overview

This study guide covers the essential topic of Managers, Leadership, and Decision Making. Examiners consistently test candidates on their ability to distinguish between management (organising resources) and leadership (inspiring people). You will need to understand four key leadership styles, apply the Tannenbaum-Schmidt continuum, calculate expected values using decision trees, and evaluate how stakeholders influence business choices using Mendelow's Matrix. Mastery of this topic requires both precise knowledge of definitions and the ability to apply these concepts to specific business scenarios.

Management vs Leadership

Managers

Role: Organise resources (people, money, time, equipment) to achieve business objectives.
Key Actions: Planning, coordinating, and controlling.
Impact: Ensure the day-to-day operations run smoothly and efficiently. "Managers do things right."

Leaders

Role: Inspire and motivate people.
Key Actions: Setting a vision, taking risks, and getting others to follow them.
Impact: Drive change and set the strategic direction of the business. "Leaders do the right things."

Leadership Styles

Examiners expect you to know four main styles and be able to recommend the most appropriate one for a given scenario.

1. Autocratic: The manager makes all decisions alone. Communication is one-way (top-down). Best for crisis situations or with unskilled workers, but can demotivate staff over time.
2. Paternalistic: The manager makes decisions but explains why, showing care for employee wellbeing. Builds loyalty but limits real employee influence.
3. Democratic: The manager consults the team widely before deciding. Boosts motivation and creativity, but decision-making can be slow.
4. Laissez-faire: Employees have maximum freedom to make decisions. Best for highly skilled professionals, but risky if staff lack direction.

The Tannenbaum-Schmidt Continuum

This model shows that leadership style is not fixed; it exists on a spectrum from boss-centred to subordinate-centred leadership.

Effective leaders adapt their style based on:

• The urgency of the decision
• The skill and experience of the team
• The nature of the task
• The culture of the organisation

Scientific Decision Making

Businesses use a structured approach to reduce risk: identify the problem, gather data, generate options, evaluate using quantitative tools, decide, implement, and review.

The most important quantitative tool is the Decision Tree.

• Square nodes: Decision points
• Circle nodes: Chance events (with probabilities)
• Expected Value: (Probability of outcome A × Financial value of A) + (Probability of outcome B × Financial value of B)
• Net Gain: Expected Value - Cost of the decision

Factors Influencing Decision Making

• Risk: The measurable chance of a negative outcome.
• Uncertainty: When probabilities cannot be reliably estimated.
• Opportunity Cost: The value of the next best alternative given up. Always include this in evaluation answers.
• Intuitive Decision Making: Relying on experience and gut feeling rather than data.

Stakeholder Mapping

A stakeholder is any individual or group with an interest in the business. Mendelow's Matrix maps them by Power and Interest.

• High Power, High Interest: Manage closely (e.g., major investors)
• High Power, Low Interest: Keep satisfied (e.g., government)
• Low Power, High Interest: Keep informed (e.g., local community)
• Low Power, Low Interest: Monitor (e.g., general public)
