Consulting Consulting
Back to overview

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.

Forvis Mazars Case: Prüfung der Carvermietungen GmbH
Sie sind Abschlussprüfer der CarVermietungen GmbH, einem deutschen Unternehmen, das geleaste Fahrzeuge europaweit an Privat- und Geschäftskunden weitervermietet. Im Rahmen der Prüfung führen Sie Interviews mit dem Management des Unternehmens durch. Dabei wecken insbesondere die langfristigen ökologischen und digitalen Herausforderungen der Firma Ihr Interesse. Sie erfahren unter anderem, dass die Hauptunterschiede zum üblichen Geschäft in einem Transformationsplan liegen und lassen sich vom CFO den Plan vorstellen. Die Finanzdirektorin teilt Ihnen stolz mit, dass die CarVermietungen GmbH in die Elektrifizierung der Fahrzeugflotte investiert. Die Anzahl der Elektroautos wird im Lagebericht veröffentlicht. Die CarVermietungen GmbH bietet ihren Kunden seit dem vierten Quartal eine Erweiterung zum bestehenden Bonusprogramm an. Die Kunden können ihre gesammelten Bonuspunkte am Jahresende auf ein Umweltprogramm übertragen, das vorwiegend in den Anbau von Bäumen und Wasseralgen investiert, um die klimafreundliche CO2-Bindung zu fördern. In diesem Zusammenhang hat das Unternehmen auch eine weitere Zielgruppe definiert und eine entsprechende Kundenliste erstellt. Darüber hinaus wurden im laufenden Geschäftsjahr durch den Zukauf von Daten über ein soziales Netzwerk zusätzlich neue Kunden hinzugewonnen. Die CarVermietungen GmbH hat im letzten Quartal außerdem in P2P-Carsharing investiert, da sich dieses neue Geschäftsmodell im Ausland bereits als vielversprechend erwiesen hat. Private Autobesitzer haben die Möglichkeit, ihr Fahrzeug über die Carsharing-Plattform anzubieten und die Vermietung gänzlich über eine App abzuwickeln. Die Mietwagengebühren betragen ein Drittel des Mietwertes und die CarVermietungen GmbH zahlt eine Versicherung, die jeden Kunden abdeckt. Die Versicherungsprämien für das Folgejahr wurden bereits ausgezahlt.

Deloitte Case: Footloose
Duraflex is a German footwear company with annual men’s footwear sales of approximately €1 b. They have always relied on the boot market for the majority of their volume. In this market they compete with three other major competitors. In the fall of 2019, Badger – one of Duraflex’s competitiors – launched a new line of aggressively priced work boots. The strong success of this line has caused Duraflex’s management to re-evaluate their position in work boots. With limited additional resources, the management must now decide if they should focus their efforts on competing with Badger in the work boot sector, or allocate their resources on further strengthening their position with casual boots. The management team approached you and asked for your advice. In order to advise them on their future work boot strategy please prepare first some insights regarding market size and competitive landscape.

Hara Coffee Co's innovative coffee subscription model
Our client, Hara Coffee Company, is a large coffee chain with over 200 locations in the United Kingdom. They import beans from numerous regions and batch-roast them in the UK, offering customers a vast selection of premium blends. In addition to serving delicious coffee, our client offers freshly made sandwiches, pastries, and salads of the highest quality. Hara Coffee Co. is also one of the most socially and environmentally responsible coffee brands in the United Kingdom, and their value proposition heavily relies on customers paying a premium for delicious products that do not compromise on sustainability metrics. The rising cost of living has significantly reduced the revenue of coffee chains throughout the United Kingdom over the past year. People are increasingly choosing to brew their own coffee at home, with beans delivered by subscription. The CEO of Hara Coffee Company is intrigued by the expansion of coffee subscription models in the UK. They requested that our team investigate whether their chain could also introduce a coffee subscription model, in which customers pay a fixed monthly fee and receive a certain number of coffees throughout the month.

Zero Carbon Mine (McKinsey 1st & 2nd round)
Client goal Our client is an international mining company Global Mining Corp (GMC) that focuses on copper mining and is interested in the possibility of producing and selling “green copper”, which is the same product as normal copper but with a certified zero carbon footprint for its entire life cycle until sale. The client engaged your team to help determine the prospects for achieving net zero for their Chilean and Australian copper mines in the next 10 years and decide whether they should pursue this path. Description of situation The client operates open pit copper mines mostly in remote areas of Chile and Australia. In most cases, the copper ore is blasted with explosives and turned into rubble, which is then collected by heavy bulldozers in big piles, loaded by power shovels onto haul trucks, which transport the material over several kilometers to the processing site. Mobile equipment is diesel operated and very heavy, up to 400 tons for a fully loaded haul truck. During processing, a series of mechanical operations take place to break down the rubble further before chemical processes like acidic leaching are used to produce the final product: copper cathodes. This material is then transported by trucks and rail to the nearest port where it can be shipped to its final destination, depending on the customer.

Business Strategy: Home Delivery Solution for Retailer Chain
Kadara, a privately-held US retailer active in the Midwest with annual sales of approximately USD 3 bn, is trying to figure out a solution to last-mile home delivery. The company currently operates out of 100 brick-and-mortar stores selling primarily groceries and home essentials (e.g. paper towels, diapers, blenders). They also sell all non-perishable products offered in their stores through their website. Currently, all sales from their website are delivered via 3rd parties (e.g. FedEx, USPS), picking up products from regional distribution centers, and their minimum delivery time is next day. Kadara does not have out-of-store delivery options but they know that services such as Instacart and Postmates are being used by customers to arrange home delivery of groceries. Kadara's management believes that they are, at best, leaving money on the table due to their limited home delivery options and, at worst, at risk of being de-selected by customers as they move towards delivery options. Kadara’s future CEO, the granddaughter of the founder, has jumped on the chance to move the company into the future. To that end, she has developed a recommendation to Kadara's board to buy Dallas Drone Technologies (DDT). DDT designs, manufactures and operates small-to-midsize flying drones. Their initial models focused on aerial photography but they added goods movement capabilities about two years ago. The future CEO believes that drone delivery is key and that Kadara should buy DDT for USD 100 m to become a leader in the space. Kadara's current CEO would like your help specifically in evaluating the option to buy DDT and generally in how to think about home delivery and the future of their business.

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.
