Intro to Marketing Research: Problem Definition and Research Objectives Symptom vs Root Cause

What It Is

Symptom vs Root Cause analysis is a marketing research method used to identify the underlying causes of a problem or issue, rather than just its surface-level symptoms. A famous example of this is the Tylenol tampering crisis in 1982, where seven people in the Chicago area died after taking Extra-Strength Tylenol capsules that had been laced with potassium cyanide. Johnson & Johnson's response was to recall all Tylenol products from the market, but they also conducted a root cause analysis to identify the underlying causes of the tampering, which led to a redesign of the packaging and a shift to triple-seal containers. This matters for marketing decision-making because it helps companies to address the root causes of problems, rather than just treating the symptoms.

Key Terms & Concepts

• Symptom: A visible or measurable indicator of a problem or issue. (Example: A decline in sales is a symptom of a larger problem.)
• Root Cause: The underlying cause of a problem or issue, rather than its surface-level symptoms. (Example: A root cause analysis might identify a lack of trust in a brand as the underlying cause of a decline in sales.)
• Fishbone Diagram: A visual tool used to identify and organize potential causes of a problem. (Example: A fishbone diagram might be used to identify the root causes of a decline in customer satisfaction.)
• 5 Whys: A method used to drill down to the root cause of a problem by asking "why" five times. (Example: A company might use the 5 Whys method to identify the root cause of a defect in their manufacturing process.)
• Pareto Analysis: A method used to identify the most common causes of a problem. (Example: A company might use Pareto analysis to identify the most common reasons for customer complaints.)
• Cause-and-Effect Diagram: A visual tool used to identify and organize potential causes of a problem and their relationships to each other. (Example: A cause-and-effect diagram might be used to identify the root causes of a decline in sales.)
• Root Cause Analysis (RCA): A systematic approach to identifying and analyzing the root causes of a problem. (Example: RCA might be used to identify the root causes of a product recall.)
• Failure Mode and Effects Analysis (FMEA): A method used to identify and evaluate potential failures in a product or process. (Example: FMEA might be used to identify potential failures in a new product design.)
• Fault Tree Analysis: A method used to identify and evaluate potential failures in a system or process. (Example: Fault tree analysis might be used to identify potential failures in a manufacturing process.)
• Systemic Thinking: A way of thinking about problems that considers the interactions and relationships between different components of a system. (Example: Systemic thinking might be used to identify the root causes of a decline in customer satisfaction.)
• Systems Thinking: A way of thinking about problems that considers the interactions and relationships between different components of a system. (Example: Systems thinking might be used to identify the root causes of a decline in customer satisfaction.)
• Causal Loop Diagram: A visual tool used to identify and analyze the causal relationships between different components of a system. (Example: A causal loop diagram might be used to identify the root causes of a decline in sales.)
• Causal Chain: A series of events that are linked together by cause-and-effect relationships. (Example: A causal chain might be used to identify the root causes of a decline in customer satisfaction.)
• Causal Path: A series of events that are linked together by cause-and-effect relationships. (Example: A causal path might be used to identify the root causes of a decline in sales.)
• Causal Model: A mathematical or statistical model used to describe the relationships between different variables. (Example: A causal model might be used to identify the root causes of a decline in customer satisfaction.)

Common Misunderstandings

• Misunderstanding: Symptom vs Root Cause analysis is only used for product recalls.
• Correction: Symptom vs Root Cause analysis is a general method used to identify the underlying causes of any problem or issue, not just product recalls. (Example: A company might use symptom vs root cause analysis to identify the root causes of a decline in customer satisfaction.)
• Misunderstanding: Root Cause Analysis (RCA) is only used for manufacturing processes.
• Correction: RCA is a general method used to identify and analyze the root causes of any problem, not just manufacturing processes. (Example: A company might use RCA to identify the root causes of a decline in sales.)
• Misunderstanding: Systemic Thinking is only used for complex systems.
• Correction: Systemic Thinking is a general way of thinking about problems that considers the interactions and relationships between different components of any system, not just complex systems. (Example: A company might use systemic thinking to identify the root causes of a decline in customer satisfaction.)

Quick Application / Identification

Scenario: A company is experiencing a decline in sales of its flagship product. The marketing team has identified several symptoms, including a decline in customer satisfaction and an increase in customer complaints. However, they are not sure what the root cause of the problem is. What should they do?

Answer: Conduct a root cause analysis to identify the underlying causes of the problem.

Explanation: Root cause analysis is a systematic approach to identifying and analyzing the root causes of a problem. By using this method, the marketing team can identify the underlying causes of the decline in sales and develop a plan to address them.
