Managing yourself: How to learn new skills
Email 2 of 7
How to learn new skills
In the previous session, we looked at the importance of both individuals and organizations getting clear about their purpose. Now we’ll hone in on the significance of learning new skills to get yourself closer to meeting your personal and professional goals.
Feeling stuck at work, and in life, is not uncommon. But it can become particularly bothersome when you’re in the position of managing others who rely on your guidance and wisdom. Fortunately, there’s a way to get unstuck: Learning new skills is key to greasing the wheels of creativity, personal development, and productivity.
Today’s fast-paced, tech-driven environment makes workplace learning even more crucial. “Sustainable prosperity will likely hinge on how well societies prepare the workforces of tomorrow,” say McKinsey’s Stephen Hall, Dirk Schmautzer, and coauthors.

Is there turbulence ahead for airlines? A leader’s guide
Leading Off
Share this email
Brought to you by Alex Panas, global leader of industries, & Axel Karlsson, global leader of functional practices and growth platforms
Welcome to the latest edition of Leading Off. We hope you find our insights useful. Let us know what you think at Alex_Panas@McKinsey.com and Axel_Karlsson@McKinsey.com.
—Alex and Axel
What’s the next destination for the aviation industry? After a postpandemic upswing in demand for air travel and improvements in the sector’s financial performance, airlines now face a more uncertain trajectory. A new McKinsey report on the state of aviation explores how economic and geopolitical tensions, consumer behavior, aircraft shortages, and other forces may shape the industry’s direction of travel. This week, we examine trends in the aviation sector and how these developments could affect travel planning for organizations—and their leaders—across industries.
The airline industry has a long record of mixed financial performance but recently saw its largest share of value-creating carriers in nearly 30 years. The airlines that reported detailed financial results recorded a collective $5 billion economic loss in 2024—a “remarkable feat” compared with the industry’s $30 billion collective economic loss in 2019, according to McKinsey’s Steve Saxon and Jaap Bouwer. They observe that recent improvements can largely be traced to better execution in six areas of value creation, among them: balancing capacity and demand, generating ancillary revenue (such as fees for premium seats and extra baggage), earning a reputation for reliability, and creating strong organizational health. In 2025, aviation leaders may need to navigate several developments that could affect economic performance, such as changes in business and consumer sentiments, a potential recession, and tariffs. “Healthier organizations will meet challenges with the cross-functional nimbleness that’s required to rapidly respond to changing external conditions,” the authors say.
That’s the number of myths about airline retailing that carriers should bear in mind as they refine their strategies. According to McKinsey’s Alex Cosmas and Nina Lind and their coauthors, these myths include the notions that more personalized offers always create better travel experiences; that travelers prefer to separately book flights, hotels, and other aspects of their trips; and that digital booking convenience has sped up travelers’ decision-making.
That’s McKinsey Senior Partner Vik Krishnan and coauthors on how airlines can modernize their planning to respond to emerging challenges. Airlines’ planning efforts are complicated by numerous factors—many of which are out of their control—including travel demand, weather, IT failures, and global crises. The authors suggest that airlines expand pandemic-era efforts that helped improve coordination between their commercial and operations functions, such as creating cross-functional planning teams, adopting agile processes, and improving tech capabilities. “While there have been green shoots, many airlines continue to plan in much the same way they have for decades,” they say. “Turning a critical eye on the current state of planning could help airlines imagine a more efficient and effective future.”
AI and analytics can be important tools to help the airline industry understand and satisfy travelers’ evolving preferences. That’s the view of British Airways (BA) CEO and chairman Sean Doyle, who is leading the largest modernization effort in the company’s history. In an interview with McKinsey Senior Partner Stephanie Hauser, Doyle notes that improving BA’s data infrastructure and employing machine learning will help improve its decision-making in areas ranging from aircraft maintenance to passenger meals. “There are ways the whole industry can use its data more effectively,” he adds. “For example, a customer flying on an airline will create about 58 different touchpoints of data. There are customers on some long-haul flights for nine or ten hours, which means there are many opportunities to give customers a more personalized experience through better use of data.”
With global uncertainty in the air, some companies are tightening travel budgets while weighing the potential business impact of geopolitical shifts. Still, overall demand for business travel has been rising after a few years of instability. McKinsey Partner Ryan Mann cites a key reason for this upturn: “People have found that there is no substitute for face-to-face engagement with their leaders and colleagues. Employees craving in-person encounters bodes extremely well for business travel.” Corporate travelers’ habits have changed in other ways. Some are extending their stays in certain destinations, alternating leisure days with workdays while they’re on the road. “It's important to remember, obvious as it may be, that business travelers have identities outside of work,” Mann says. “Many of the same elements that can inspire and energize them when engaging in leisure travel might also enhance their business outings.”
Lead by keeping tabs on aviation trends.

How can CIOs address rising geopolitical risks?

Under pressure. In the past decade, geopolitical developments have put the global IT operating model under immense pressure—and corporate CIOs are on the front line. They are confronting a patchwork of data laws, increased costs and complexity, and escalating cyberattacks. But current IT policies and models generally aren’t up to the task of addressing the range of geopolitical risks, McKinsey Partner James Kaplan and his coauthors explain. They say that CIOs will need to revise their risk practices, create new ones, and adjust their global operations—by, for example, partnering with business leaders to help shape decisions regarding geopolitical risk.

Building auth in Next.js means managing redirects, handling tokens and sessions, and making sure it all works across routes—even in edge environments like Vercel.
WorkOS AuthKit solves this with a fully hosted login UI that supports SSO, MFA, passwordless auth, and password-based login. It handles redirects, token exchange, and session logic with minimal config.
Install the SDK, configure your redirect URI, and initialize the AuthKitProvider. AuthKit handles login and session logic from there.

Trillions of Web Pages: Where Does Google Store Them?
How Do Companies Ship Code to Production?
Here are 11 steps from planning to production:
The Product Owner starts the entire process by creating user stories in a tool like Jira.
The Developer Team performs Sprint Planning activity and adds the user stories to the sprint.
Developers work on the assigned stories. Once a story is finished, they commit the code to Git and push it to GitHub.
Jenkins builds and runs the code through testing and quality check tools such as JUnit, Jacoco, and SonarQube.
If the build is successful, it is stored in the artifactory such as JFrog. Jenkins also deploys the build to the Dev Environment via Docker.
Next up, the feature gets deployed to the QA environment. Since multiple teams may be working on the same code base, multiple QA environments will be created
The QA team uses a particular QA environment and runs multiple test types such as QA, regression, and performance.
Once the QA verification is complete, features are deployed to the UAT (User Acceptance Testing) environment.
UAT testing verifies whether the feature satisfies the user’s requirements.
Once the UAT testing is successful, the builds become release candidates. They are deployed to the production environment based on a specific schedule.
The SRE team uses tools like ELK and Prometheus to monitor the production environment and handle alerts in case of issues.
Over to you: Will you add any other steps to the process?
What is Event Sourcing? How is it different from normal CRUD design?
The diagram below shows a comparison of normal CRUD system design and event sourcing system design. We use an order service as an example.
The event sourcing paradigm is used to design a system with determinism. This changes the philosophy of normal system designs.
How does this work? Instead of recording the order states in the database, the event sourcing design persists the events that lead to the state changes in the event store. The event store is an append-only log. The events must be sequenced with incremental numbers to guarantee their ordering. The order states can be rebuilt from the events and maintained in OrderView. If the OrderView is down, we can always rely on the event store which is the source of truth to recover the order states.
Let's look at the detailed steps.
Non-Event Sourcing
Steps 1 and 2: Bob wants to buy a product. The order is created and inserted into the database.
Steps 3 and 4: Bob wants to change the quantity from 5 to 6. The order is modified with a new state.
Event Sourcing
Steps 1 and 2: Bob wants to buy a product. A NewOrderEvent is created, sequenced, and stored in the event store with eventID=321.
Steps 3 and 4: Bob wants to change the quantity from 5 to 6. A ModifyOrderEvent is created, sequenced, and persisted in the event store with eventID=322.
Step 5: The order view is rebuilt from the order events, showing the latest state of an order.
Over to you: Which type of system is suitable for event sourcing design? Have you used this paradigm in your work?
How Data Lake Architecture Works?
A data lake is a centralized storage system that holds large volumes of structured, semi-structured, and unstructured data in its raw form. It allows organizations to store data at scale and process it later for different requirements.
Here’s how it works on a high level:
Data from diverse sources like S3, Excel files, databases, videos, images, sensors, and PDFs is collected for ingestion.
Ingestion happens via real-time streaming or batch/scheduled jobs, depending on the data type and source.
Ingested data is first stored in a raw data store before any transformation or processing occurs.
Data is then processed through batch or real-time processing systems to clean, transform, and prepare it for use.
The processed data is stored and made ready for downstream consumption by various tools and platforms.
Final data consumption happens through dashboard, AI models, data warehouse, real-time alerts, and reporting systems.
Over to you: What else will you add to better understand the Data Lake Architecture?
How Netflix Built a Distributed Counter
The Netflix distributed counter is a masterclass for learning system design.
A Distributed Counter is a system where the responsibility of counting events is spread across multiple servers or nodes in a network. Netflix needs to track and measure multiple user interactions to make real-time decisions and optimize its infrastructure.
For this reason, they built a Distributed Counter Abstraction.
Netflix’s Distributed Counter Abstraction operates in four main layers, ensuring high performance, scalability, and eventual consistency.Client API Layer
Users interact with the system by sending AddCount, GetCount, or ClearCount requests. The Netflix Data Gateway efficiently processes and routes these requests.Event Logging and TimeSeries Storage
Events are stored in Netflix TimeSeries Abstraction for scalability. Each event is tagged with an Event ID to ensure idempotency. To avoid database contention, events are grouped into time partitions known as buckets. Data is stored in Cassandra.Rollup Pipeline or Aggregation
Rollup Queues collect event changes and process them in batches. Aggregation occurs in immutable time windows, ensuring accurate rollup calculations. Data is stored in the Cassandra Rollup Store for eventual consistency.Read Optimization (Cache & Query Handling)
Aggregated counter values are cached in EVCache for ultra-fast reads. If a cache value is stale, a background rollup refresh updates it. This model allows Netflix to process 75K requests per second with single-digit millisecond latency.
Reference: Netflix’s Distributed Counter Abstraction
How TCP Handshake Works?
There are three steps in the handshake process:
SYN (Synchronize)
Think of it as one party extending its hand for a handshake. The process starts with the client sending a TCP segment to the server with the SYN flag. Also, an initial sequence number (ISN) is sent along with the message.SYN-ACK
This is like the second party agreeing to the handshake. The server receives the SYN segment and responds by sending a TCP segment to the client. It sets the SYN flag and the ACK flag in the segment. The ACK flag is meant to acknowledge the receipt of the client’s SYN segment by incrementing the ISN.ACK
This is where the two parties shake hands. The client receives the SYN-ACK segment and acknowledges the server’s response by sending another TCP segment with the ACK flag set. The sequence number is set to the server’s ISN after incrementing.
Some more points worth considering:
SYN and ACK are control flags used to manage different aspects of the communication process.
Sequence numbers (ISN) help the client and server keep track of the message order so that nothing gets missed.
Over to you: What else will you add to understand the TCP Handshake process in a better way?
