Code Brain | Ram Charan: What Managers Must Do to Face a Recession

We have entered an era of persistently sluggish economic growth. A barrage of challenges has caught entrepreneurs off guard — rising costs across the board, ongoing resource shortages, and pricing adjustments that are agonizingly difficult and often lag behind cost increases. Yet dramatic shifts in the external environment can also become historic opportunities to reshape business operations and position for the future.

The fate of an enterprise hinges on its people. The fate of an enterprise hinges on its leadership. Crisis conceals opportunity; leaders must mobilize the entire organization, strive to turn change into advantage, and continue creating new value for customers, shareholders, and other stakeholders. No matter how tough things get, don't complain about the hand you've been dealt — playing it well is the real skill.

Many Chinese enterprises and entrepreneurs emerged alongside reform and opening-up, took off rapidly after China's accession to the World Trade Organization, and grew up in a macro environment of high growth, low interest rates, and sustained economic improvement. Riding the momentum of the times, they enjoyed the dividends of development and grew accustomed to high-speed growth and scale supremacy.

But fortune is fickle. Almost overnight, we have entered an era of persistently sluggish economic growth. A barrage of challenges has caught entrepreneurs off guard — rising costs across the board, ongoing resource shortages, and pricing adjustments that are agonizingly difficult and often lag behind cost increases.

But whether or not they have experienced this before, whether or not they have relevant experience, business leaders must step forward and guide their enterprises through the difficulties. At the same time, they must shift their mindset and recognize that crisis conceals opportunity. Dramatic shifts in the external environment can also become historic opportunities to reshape business operations and position for the future. No matter how difficult things become, hard times will eventually pass; in three or four years, the skies may clear. When that time comes, enterprises that want to seize the initiative during economic recovery with stronger core capabilities need to start laying the groundwork and preparing now.

Eight Rules for Understanding the Current Economic Situation

As a business leader, you likely don't need complex data and charts to feel acutely the cost pressures brought by economic recession. But gut feeling alone isn't enough — you also need to deeply understand recession's far-reaching effects on every aspect of business operations, on industries, and on the overall economy. Here are eight rules for judging economic recession. Hopefully they will help you anticipate and prepare in advance. Bear in mind that many people only come to their senses when the situation is already upon them; unfortunately, by then it's usually too late.

Rule 1: Enterprises will consume more capital

Recession and stagflation drive up costs, meaning enterprises must invest more capital to produce the same quantity of goods. From a capital chain management perspective, whether existing as inventory before sale or as accounts receivable after sale, this means greater cash flow is tied up. And in this macro environment, the more business expands, the greater the drain on cash flow.

Rule 2: High cost pressure is difficult to fully pass downstream

Typically, increased cost pressure transmits downstream step by step along the industry value chain, altering each company's profitability and bargaining power along the way. However, in a recessionary environment, this pressure is difficult to fully pass downstream — after all, end consumers' capacity to absorb costs is limited. Once that threshold is exceeded, consumers will "vote with their feet," causing overall market demand to decline, which creates even larger industry-wide problems.

Rule 3: Macro indicators offer little guidance for specific enterprises

Take inflation indicators as an example. The commonly used metric for measuring inflation is the familiar CPI. Yet CPI measures the overall macroeconomic situation and cannot accurately reflect inflation's impact on specific industries or specific enterprises. To truly understand how economic conditions affect your own business, you must start from the actual circumstances of operations and supply chains, analyzing specific situations on their own terms.

Rule 4: The effects of recession compound continuously

Many view recession through a static lens. Yet from a developmental perspective, recession is like a snowball — its effects compound continuously. Take the inflation environment in the United States as an example. Assume year one inflation is 7%; in year two, that same inflation rate means a 14.5% increase relative to the original baseline; in year three, that same rate means a 22.5% increase relative to the original baseline. Sustained increases of this magnitude over several years will inevitably push some enterprises beyond their breaking point.

Rule 5: Recession creates psychological volatility, which in turn fuels further momentum

Economic fluctuations create psychological volatility. Under inflation, the more people fear price increases, the more they tend to stockpile; the more they stockpile, the more supply-demand imbalances worsen; the greater the supply-demand gap, the more prices skyrocket; the more prices skyrocket, the more people stockpile even more. Under deflation, sustained price declines create supply surpluses, which is equally unfavorable for enterprise development.

Rule 6: Changing input-output ratios requires re-examining established investment plans

Recession significantly impacts enterprise investment planning. Previous input assumptions and output projections may deviate substantially due to inflation or deflation. Enterprises must adjust relevant assumptions and projections based on economic conditions and re-examine previously made investment decisions. Established investment plans may well be overturned — be mentally prepared for this.

Rule 7: Responding to recession must not come at the cost of customer trust

Faced with enormous cost pressure, don't panic and resort to desperate measures, especially sacrificing long-built customer trust to protect short-term profitability. Understand this: once brand image is damaged and customer trust is lost, attempting to repair and make a comeback may prove harder than reaching the heavens.

Rule 8: Economic downturn will inevitably reshape industry competitive dynamics

Understand that the current economic environment is both challenge and opportunity, and will inevitably reshape industry competitive dynamics. Enterprises that passively wait and sit on their hands will likely suffer heavy damage or even be eliminated; enterprises that can both manage short-term responses and lay groundwork for the future, building a foundation for long-term development, will likely emerge as future winners.

Based on these rules, you'll find that many enterprise leaders have been too slow to act and too limited in their approaches in responding to the broad trend of recession. Blind cost-cutting is merely a stopgap measure — an enterprise might survive one year, but if recession persists for several years, it will inevitably become unsustainable.

Five Strategies for Breaking Through Economic Recession

Activate wartime readiness and seize the initiative

Faced with sudden economic shocks, some enterprises have mature response mechanisms — they can detect signs of major change earlier and formulate comprehensive response strategies, preparing in advance and gaining first-mover advantage. Catalent, the global leader in contract development and manufacturing organizations (CDMOs), is one such enterprise that understands "preparing for a rainy day." In early 2021, amid intensifying inflation and surging personnel costs, it conducted trend analysis and corresponding deployment across all links in its industry chain. Its CEO John Chiminski said: "In this situation, even if you can't control the trend, you must at least go with it — you absolutely cannot fall behind by even a fraction."

As early as June 2021, they detected the phenomenon of industry-wide salary increases. "During that period, recruitment difficulties appeared across all industries. The biopharmaceutical industry has high talent requirements, making recruitment even more challenging. Take our company as an example: our turnover rate is typically around 9%, but it jumped to 11% in 2021 and reached as high as 13% in the first half of 2022, with new employee onboarding training volume doubling." Talent is the foundation of an enterprise; with industry-wide salary increases and surging labor costs, plus soaring raw material costs, what happens to profitability? The situation was urgent, and Chiminski immediately convened his core team for joint discussion.

This is the purpose of establishing a "war room." In critical moments, every enterprise needs such a mobilization mechanism — one that makes everyone immediately recognize the severity of the problem and the urgency of time, and immediately enter a state of combat readiness. You can call it by a different name, but you must never treat crisis response as just another agenda item in regular meetings, discussed and decided through routine procedures.

Discussions in the "war room" cannot stay superficial, focusing only on the present and treating symptoms rather than root causes. They must include not only tactical discussions on how to respond to disasters, but also strategic thinking — based on data and scenario analysis, conducting trend assessment and response planning, thinking about how to prevent and mitigate disasters. When closely monitoring emerging changes and warning signals, you must judge not only the direction of development but also the speed of development; only then can you possibly prepare in advance, seize the initiative, and gain first-mover advantage.

Cash management is a matter of survival

Cash management is a matter of enterprise survival and the key to safely navigating recession. At all times, enterprise leaders must have a clear grasp of cash sources, cash uses, and cash changes. They must also vigorously reduce costs and increase efficiency, striving to achieve cash flow break-even at lower revenue levels. For financial statements, don't focus only on the income statement — pay attention to the balance sheet and cash flow statement as well. For profitability, don't focus only on book profit and profit margins — pay even more attention to cash profit.

If you don't take cash seriously and implement no control measures, your enterprise will sooner or later find itself in precarious circumstances. The impact of a major recession is broad and deep; previous optimistic calculations may well fall through. For example, fixed-price orders will see profits eroded once costs rise sharply; variable-rate loans will see interest expenses soar once rates rise sharply; energy-intensive industries will suffer direct or indirect heavy blows to operations once energy prices spike.

In this macro environment, all aspects related to customer service and revenue — such as receivables, inventory, and production — can potentially become major cash drains. Every customer's situation differs; a customer with payment terms as long as 275 days, even if highly profitable, likely doesn't look good on the books. For example, after conducting a customer inventory, one major U.S. bank discovered that several large enterprise clients had enormous negative impacts on its overall balance sheet, and decisively chose to terminate those relationships.

Under the trend of rising interest rates and slowing economic growth, enterprises must manage cash even more carefully, quickly identifying and resolving bottlenecks and bleeding points. Whether operating expenses or capital expenditures, exercise doubled caution. All business planning and forecast analysis must include cash flow analysis; even investment plans already approved must be re-analyzed and re-decided based on current macro changes and future trend projections.

Adjust pricing quickly

Crisis conceals opportunity. Enormous cost pressure will force enterprises to adjust pricing, making this an excellent opportunity to rethink pricing methods. To seize this opportunity, you must first structurally deconstruct your pricing approach and clarify what exactly we're talking about when we discuss pricing in general terms.

• Revenue model: Are you charging by one-time transaction, ongoing subscription service, or case-by-case contract?
• Pricing mechanism: Are you referencing competitors, referencing indices, using continuous dynamic adjustment, or conducting one-on-one price negotiation?
• Pricing objective: Is it to avoid idle capacity, meet profit margin targets, meet price targets, or maximize total profit?
• Pricing strategy: What is the strategic intent behind pricing — to increase market penetration, stabilize existing customers, or maximize value creation?

Whatever combination of these pricing elements you used in the past, you should now consider: Should you make changes now? After the 2008–2009 financial crisis, one U.S. crane manufacturer successfully extricated itself from difficulties through proactive pricing transformation. At the time, the economy was extremely weak, the shipping industry had suffered heavy blows, and demand for container-handling cranes was severely affected. The company had already invested heavily in building these multi-million-dollar cranes; reducing or halting production would not only cause enormous losses but also render previous investments worthless. Misfortunes never come singly — right then, news of order cancellations came one after another.

Subsequently, the company innovatively changed its revenue model, shifting from selling cranes to shipping companies to charging per container lift. This was highly attractive to shipping companies as well: instead of paying high upfront crane purchase costs, they only paid per actual use. Thus, in an extremely difficult macro environment, the crane manufacturer gradually completed its revenue model transformation, and customers gradually accepted the container lifting service and its pricing. When the shipping industry recovered four or five years later, container lifting services had become a highly profitable new business. Faced with adversity, this company didn't sit idle waiting to die — it actively sought change, using proactive pricing transformation as a key breakthrough point. Not only did it safely navigate the economic crisis, but it also laid a solid foundation for vigorous development after recovery.

By contrast, some pricing combinations are quite dangerous. For example, one contract manufacturing enterprise (revenue model), to ensure full factory capacity utilization (pricing objective), signed a five-year contract with a client two years ago with locked-in prices and no adjustment mechanism. Faced with high inflation and soaring raw material and labor costs, if the enterprise doesn't take decisive measures, it will inevitably fall into the abyss of cash flow exhaustion or even bankruptcy.

Though every enterprise's situation differs, value-based pricing is the general trend and worth serious consideration by more enterprises.

Reduce costs and increase efficiency to support development
