MANG2069 Making Successful Decisions

Module Overview

This module considers the generic aspects of decision processes that take place at individual and organisational levels and demonstrates how various lines of enquiry and analytical techniques can help achieve better quality decisions. It draws sharp attention to the central, yet often neglected, role that judgment and decision making play in determining fortune or failure in all areas of our professional and personal lives. To this end, students are exposed to a range of theoretical perspectives, research findings and historical examples that highlight the limitations and shortcomings of many commonly used approaches to decision making. Students will then learn how to utilise a range of qualitative and quantitative analytical methods to help them better understand and make decisions. They will practice thinking critically about the strengths and weaknesses of these methods in order to develop the ability to select the most appropriate decision analysis technique(s) for each situation. The module, therefore, provides students with (i) a deep appreciation of how decision processes impact on the ability of individuals and organisations to effectively achieve objectives (ii) comprehensive knowledge of the limitations and biases inherent in human judgment and (iii) the ability to select and apply a range of decision making tools and techniques based on a critical understanding of the extent to which such approaches can facilitate successful decision making.

Aims and Objectives

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • the limitations and biases inherent in many judgment and decision making processes;
  • decision analysis techniques and the circumstances under which each technique is best applied;
  • the relative strengths of various decision making processes and decision analysis techniques.
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • identify when and how cognitive limitations and biases can have a detrimental influence on judgments and decisions;
  • use prescriptive and descriptive theories to understand and analyse judgments and decisions;
  • apply and critically evaluate decision-making models and decision analysis techniques.
Transferable and Generic Skills

Having successfully completed this module you will be able to:

  • identify the limitations to and consequences of commonly used approaches to decision making and problem solving;
  • use a range of approaches to critically analyse and evaluate theoretical perspectives and research evidence;
  • use frameworks and analytical techniques to better understand simple and complex problems and to identify effective solutions.


The module syllabus is organised into two parts: Part 1: Decision Processes This part of the module examines the general nature and structure of decision making processes, explores commonly used decision strategies, and identifies some of the key factors that underlie systematic judgmental biases and poor decision making. The material covered in this part is largely drawn from the disciplines of cognitive psychology, social psychology and behavioural economics. Emphasis is placed on critical comparisons between different theories/findings and on the potential of decisions to have far-reaching consequences in and beyond the context in which they are made. The subjects covered in Part 1 are:  An Introduction to Decision Making Processes Decision Making and the Classical Decision Making Module Probability Judgment and Heuristics information Processing and Bounded Awareness Utility and Prospect Theory Mental Accounting Choice Architecture Emotions, Ethics and Honesty in Decision Making Group Decision Making Processes Part 2: Decision Analysis This part reviews and applies many key concepts and techniques from the discipline of decision analysis. These techniques can aid decision making under risk and uncertainty and overcome the challenges of decision complexity. The material covered in this part is largely drawn from the disciplines of operational research, economics and decision analysis. Emphasis is placed on understanding the conditions under which specific techniques are most appropriate and on thinking critically about the relative merits of each approach for the given context. The subjects covered in Part 1 are: Decision Making Under Risk and Uncertainty Decision Trees The Value of Information and Bayes Theorem Competitive Decision Making Cooperative Decision Making Multi-Attribute Decisions Multi-Criteria Decision Analysis Attitudes to Risk and Risk Efficient Choices
