Candidates often face the challenge of choosing between pre-defined frameworks and custom solutions. In case interviews, candidates may struggle with this balance. Some consultants, as discussed at a recent McKinsey event, suggest developing tailored approaches rather than using existing frameworks, while others find that established models and past experience are valuable.
As explained in this section, for beginners, we recommend using popular frameworks as they offer a reliable foundation and help avoid inconsistencies. Relying solely on intuition can lead to less structured hypotheses. Established frameworks provide a solid base for effective case structures.
Understanding Inductive and Deductive Approaches to Case Interview Solving
1. Inductive Approach
Case interviews present real business problems based on the interviewer's past work experiences. These problems are designed to reflect the actual challenges faced by clients rather than being theoretical puzzles. This approach allows candidates to understand the type of work consultants do and the impact they have on clients.
Definition: The inductive approach draws general conclusions from specific observations. It’s a bottom-up method where you gather data, identify patterns, and formulate broader theories.
Process:
Gather Data: Collect relevant data points and observations.
Identify Patterns: Analyze the data to find recurring themes or anomalies.
Formulate Hypotheses: Develop generalizations or hypotheses based on the patterns.
Draw Conclusions: Validate the hypotheses with additional data or reasoning.
Example:
A company’s sales are declining. Using the inductive approach, you start by examining detailed sales data, customer feedback, and market conditions. You might notice that sales decline more steeply in certain regions or customer segments. From these observations, you could infer broader issues, such as regional competition or shifting customer preferences.
2. Deductive Approach
Case interviews present real business problems based on the interviewer's past work experiences. These problems are designed to reflect the actual challenges faced by clients rather than being theoretical puzzles. This approach allows candidates to understand the type of work consultants do and the impact they have on clients.
Definition: The deductive approach starts with a general hypothesis and tests it through specific observations. It’s a top-down method where you begin with a broader premise and seek data to confirm or refute it.
Process:
Formulate Hypothesis: Start with a broad hypothesis based on existing knowledge.
Develop a Framework: Create a logical framework to test the hypothesis.
Gather Data: Collect specific data to confirm or refute the hypothesis.
Test Hypothesis: Analyze the data against the framework.
Draw Conclusions: Conclude based on whether the data supports or contradicts the hypothesis.
Example:
If the hypothesis is that declining sales are due to poor customer service, the deductive approach involves gathering data on customer service performance, complaints, and satisfaction scores. You then analyze this data to see if poor customer service correlates with the decline in sales, confirming or refuting your hypothesis.
Comparative Example:
Case: A company is experiencing declining sales.
Deductive Approach:
Hypothesis: Sales decline due to increased competition.
Steps: Analyze market share, competitor actions, and customer preferences.
Conclusion: Validate or refute the hypothesis and provide recommendations.
Inductive Approach:
Start: Collect and analyze sales data, customer feedback, and market trends.
Steps: Identify patterns (e.g., customer demographics, purchase behavior).
Conclusion: Formulate theories based on data patterns and provide recommendations.
