Business Sense

Business sense refers to the ability to quickly grasp economic dynamics and make decisions that are both strategically and commercially sound. In consulting, it’s not enough to repeat theories from your business degree. What matters is a deep understanding of how companies operate, what drives markets, and what different stakeholders are aiming to achieve.

Consultants with strong business acumen can quickly adapt to new industries, understand client needs, and set priorities that make economic sense. They don’t just ask, “What is analytically correct?” – they also ask, “What truly benefits the company?” This mindset often makes the difference in a case interview.
 

 

Why Your Business Sense Matters in Consulting

As a consultant, you’re expected not only to analyze complex problems but also to think in a solution-oriented and entrepreneurial way. A strong business mindset helps you put analyses into context, assess actions realistically, and focus on generating maximum client value.

In day-to-day consulting, you're working under pressure, collaborating with decision-makers, and constantly weighing trade-offs. Those who think commercially and can strategically prioritize have a clear edge.

In a case interview, showing that you understand markets and business models is key – it sets you apart and proves your readiness for the job.

👉 In our Case Library, you can prepare effectively with curated practice cases and put your business sense to the test.

Stern Stewart Case: TexGroup – Breaking the crisis of a traditional textile company
TexGroup is a family-owned German heritage company, now in its third generation of leadership. Specializing in high-quality, Made-in-Germany textiles, the company operates across four distinct product segments: TexCasual, TexPremium, TexSport, and TexProfessional. TexGroup supplies its products to a diverse portfolio of fashion brands, with a strong focus on the European market. In recent years, TexGroup has faced increasing financial pressure, with steadily declining profit margins. The recently concluded 2024 fiscal year closed with a historically low EBIT margin of just 0.6%, raising serious concerns among management about a continued downward spiral that could push the company into financial losses. To stop this negative trend and secure long-term success, TexGroup is seeking an external consulting team to setup and implement a structured turnaround program. The primary target is to achieve 10% sustainable EBIT margin within two years. Note: During our assessment day, candidates could receive a laptop and an Excel file to analyze data and perform calculations. While this case can be solved without the Excel file, downloading it allows for a more pragmatic experience. Download the file here.

Roland Berger Case: Launch of a Mobile Neobroker
"FemVest" is a venture-backed fintech aiming to launch a mobile neobroker in Germany in 2026. The company believes that women are structurally underserved in the area of retail investing: women are less likely to hold a securities account, invest smaller amounts on average, and enter the market later than men. At the same time, the financial relevance of women is growing — driven by rising incomes, demographic shifts, and inheritances. FemVest has already secured regulatory approval as well as a custodian bank and execution partner. However, key strategic decisions remain open: the target segment has not been finalized, the product and service offering is not yet defined, the business model has not been established, and the go-to-market strategy has not yet been developed. The board is asking you, as a consultant, to analyze the market potential, develop an initial business case, and derive concrete strategic recommendations for market entry.

Commercial Feasibility of Natural Gas Pipeline
A large natural gas field is unexpectedly discovered on the Mediterranean island of Corsica. The gas can be accessed and produced relatively easily and is of good quality. Europe, and especially Germany as the largest gas consumer in the EU, is looking for alternative gas suppliers to reduce its one-sided dependence on Russia. An initial market study has shown that stable demand in Western Europe would allow for around 10 billion cubic meters (bcm) of natural gas per year from the new gas field to be sold on the European market for the next 25 years. To achieve this, however, the gas must be transported to the important Western European gas hub Baumgarten in Austria. Several large oil and gas companies sense a business opportunity here and are now asking themselves whether it is economically feasible to build a corresponding gas pipeline from Corsica to Austria. One of these companies has approached you as a consultant to provide your assessment.

How Business Sense Shows Up in Case Interviews

Your business sense won’t be tested directly – but it shows up in your thinking, your assumptions, and your recommendations. Here are five moments when it really counts:

5 tips on how to show business sense in case interviews

1. Define a clear objective.

Clarify what the company wants to achieve in the case. Is it short-term profit, long-term growth, or a stronger market position? A well-defined goal aligns your analysis and recommendations – and shows you understand the business context.

2. Develop sound hypotheses.

Top candidates derive economically plausible hypotheses. If revenue is dropping, explore potential causes like demandpricing, or competitive pressure.

3. Evaluate actions realistically.

Go beyond theory. Consider real-world feasibility, conflicting objectives, and strategic risks. Instead of simply saying “raise prices,” consider price elasticity, customer segments, and likely competitor reactions.

4. Interpret numbers in the right context.

Numbers only make sense when interpreted correctly. High margins might signal a premium position – or upcoming competitive threatsBusiness sense means understanding what the numbers imply in context.

5. Make a well-founded recommendation.

Your final recommendation should be logical and economically viable. Acknowledge risks or gaps, and show that your solution could succeed in the real world.
 

How to Train Your Business Sense

Business sense isn’t innate – it’s a skill you can develop. The key is to build a solid understanding of economic principles and learn how real-world decisions are made.

Start by regularly reading business news. Outlets like New York Times, the Wall Street Journal or the Financial Times will help you get a feel for marketsbusiness models, and strategic thinking. Go beyond the facts – try to understand the economic rationale behind each story.

When practicing case interviews, stay sharp and reflective. Ask yourself: Is my reasoning not only logical but also economically sound?

Mock interviews with peers are especially helpful. You’ll improve your communication skills and receive valuable feedback.

Also, think like an entrepreneur in daily life. Observe companies, analyze new strategies, and reflect on what drives success or failure. The more often you go through this process, the sharper your business intuition becomes – and that’s what sets you apart in interviews.
 

Key Takeaways

Business sense is one of the most important success factors in both consulting and case interviews. It reflects your ability to quickly recognize economic patterns, form sound assumptions, and make realistic, client-oriented decisions. In interviews, what sets top candidates apart isn’t memorized theory but the ability to see the bigger picture: understanding what really matters to a business, prioritizing strategically, and proposing solutions that are both practical and value-driven.

To demonstrate your business sense, it’s crucial to clearly define the objective of the case, develop plausible hypotheses, assess potential actions not only analytically but also from a business standpoint, and interpret numbers within the correct context. Your final recommendation should be not just logical, but economically viable and well thought through.

The good news is that business sense can be learned. By regularly reading business news, reflecting on strategic decisions, working through case interviews critically, and actively seeking feedback, you’ll build a strong foundation in economic thinking. Over time, this mindset will not only boost your interview performance but also set you up for long-term success in consulting.

Presentation and Communication
Consulting Skills & Preparation
The majority and the most obvious part of preparation is, of course, the substantive preparation for your case interview. However, you also need to present what you have learned in a way that gives your interviewer an impression of your personality and character. This means that you must appear confidentand communicate clearly and precisely. The best preparation is useless if you come across as closed-off and insecure. As a consultant, you must always appear trustworthy and confident when interacting with clients to be taken seriously and to enable you and your team to work in a solution-oriented manner. This is already tested in the case interview – albeit indirectly ;)

General Knowledge
Consulting Skills & Preparation
In case interviews, having solid general knowledge can make a big difference, especially in market sizing questions. Knowing basic facts about regions, population sizes, and economic indicators helps you build stronger arguments. It’s not just about the analysis itself but also about showing interviewers that you understand global trends and can quickly process key information — an important skill in consulting. In a case interview, quick and accurate estimates are essential. For example, if you're asked to evaluate the potential market for a product in a specific country, having solid data — like the population size — is crucial. Without this information, it can be challenging to make a meaningful calculation. In addition to national market data, it's important to know about key global markets. Being familiar with major economic regions like the U.S., China, and the EU is valuable because large consulting firms such as McKinsey and BCG operate extensively in these areas. A solid understanding of these regions shows that you can think about global factors and helps you stand out from other candidates. What Your Knowledge of Population, Economy & Geography Says About You Having strong general knowledge in specific areas not only shows that you are well-prepared, but also that you can quickly understand economic relationships—a crucial skill in consulting. When you have information like population sizes or a country's Gross Domestic Product (GDP) at your fingertips, you can quickly verify assumptions and make informed decisions, which is exactly what case interviews expect. Additionally, your knowledge of these topics demonstrates a genuine interest in world affairs and your ability to recognize and understand global trends. This insight is vital for evaluating how political, economic, and social changes affect businesses. It also highlights your capability to absorb and use complex data effectively. Population Country/Region Population (approx.) Worldwide 8.05 billion China 1.426 billion India 1.419 billion Europe (EU states) 450 million USA 335 million Indonesia 277 million Brazil 203 million Russia 143 million Japan 124 million Germany 83 million UK 68 million GDP Forecast in USD for 2024 Country/Region GDP 2024 (approx. in trillions USD) Worldwide 105 trillion USD USA 25 trillion USD China 18 trillion USD Japan 4.3 trillion USD Germany 4.5 trillion USD France 3.0 trillion USD UK 3.1 trillion USD India 3.9 trillion USD Italy 2.2 trillion USD Brazil 2.1 trillion USD Canada 2.2 trillion USD Key Data to Know for Your Case Interview In case interviews, making quick and accurate estimates is key. A good grasp of units, along with basic fraction and percentage calculations, is essential for working efficiently. Additionally, being comfortable with time units is important for making rough estimates and calculations. The table of larger and smaller time units below provides a handy overview of commonly needed values. These fundamental skills help you tackle tasks confidently and quickly.
