The future of gen AI in 15 charts
The CEO Shortlist
Share this email
Curated by Liz Hilton Segel, chief client officer and managing partner, global industry practices, & Homayoun Hatami, managing partner, global client capabilities
The CEO role has never been easy: the boss is ultimately in charge of forming the company’s new strategies, then marshaling the resources to deliver on them. But what we’re hearing now from the world’s CEOs is that their role is harder than ever. Accordingly, we’re doubling down on our commitment to support them. Our CEO Excellence research is generating a steady stream of insights on how the best CEOs consistently deliver results. And other colleagues continue to surface the issues that matter most to CEOs and their teams in the C-suite. In line with that, we’ve changed the focus (and the name) of this newsletter to signal our commitment to helping CEOs—both present and future—do the best jobs they can. Rest assured, we will continue to deliver, twice monthly, four articles and reports that are must-reads for people across the workforce—from C-level execs to the front line. In this edition, we look at the future of generative AI, software developer productivity, and more. We hope you enjoy the read.
—Liz and Homayoun
All gen AI, all the time. It might feel like overload, but gen AI is just getting started. With so many current use cases—and hundreds, if not thousands, more on the horizon—knowing how to apply the technology to your business can seem daunting. To help, we’ve pulled together 15 of our most insightful charts, not only to offer ideas about where gen AI is headed, but also to help business leaders in a wide variety of industries put this tool to work, creating efficiencies and value.
Peer with us into the crystal ball with What’s the future of generative AI? An early view in 15 charts, a new visual McKinsey Explainer.What do you call it when carmakers sell insurance, bankers sell furniture, accountants sell HR services, and a few superapps sell all the above and more? We call it the ecosystem economy. Senior partners Venkat Atluri and Miklós Dietz have documented a massive shift from industry sectors to customer-focused ecosystems and make the case that this might be the biggest economic reorganization in history. What will it mean for your company?
Read or listen to the latest episode of our Inside the Strategy Room podcast, Strategies to win in the new ecosystem economy, and order the book if you’d like to go deeper.Growing the top line is good. Growing the bottom line is better. And best of all is growth that accrues to the benefit of all stakeholders. Our new research finds that companies that are “triple outperformers”—meaning they grow faster and are more profitable than peers while also improving sustainability and ESG efforts—exceed their peers in shareholder returns.
Hit the trifecta with The triple play: Growth, profit, and sustainability, by Rebecca Doherty, Claudia Kampel, Anna Koivuniemi, Lucy Pérez, and Werner Rehm.We hope you find our new focus on CEOs inspiring and helpful. See you in two weeks with four more McKinsey ideas for the CEO and others in the C-suite.

We knew her when: Unilever’s past CHRO (Chanel’s new CEO) on reimagining work
On Point
Brought to you by Liz Hilton Segel, chief client officer and managing partner, global industry practices, & Homayoun Hatami, managing partner, global client capabilities
•
Break with tradition. The COVID-19 pandemic broke traditional models of employment, says Leena Nair, former CHRO of Unilever, in an interview with McKinsey alum Mary Meaney. Creating personalized solutions for employees in 190 countries has been a huge challenge, Nair explains. To help, Unilever developed a platform called COVID Awareness and Situation Intelligence that can predict infection and hospitalization rates. Local leaders were able to use the platform’s data to decide when to open an office.
•
Working dynamically. Even before the pandemic, Unilever was investing in digital tools that enable people to work fluidly, Nair says. One digital tool matches people who have capacity in particular areas with those who are looking for those skills. In 2020, that enabled Unilever to move resources from the hard-hit parts of the business to those that were growing. About 10,000 employees have been redeployed or have used the platform, Nair adds. See five lessons Unilever’s past CHRO says she’s learned since the COVID-19 pandemic began.

How to Choose a Replication Strategy
How to Choose a Replication Strategy

Latest articles
If you’re not a subscriber, here’s what you missed this month.
To receive all the full articles and support ByteByteGo, consider subscribing:
In the last issue, we kicked off a 2-part series exploring common data replication strategies. We learned about the leader-follower model - its synchronous and asynchronous variations, consistency considerations, failure handling, and more.
In this issue, we'll examine two alternative approaches - multi-leader and leaderless replication. We'll contrast their designs, dive into how they work, and see the types of use cases where they excel.
By the end, you'll understand the core replication models and how to select the right strategy based on your system needs and constraints. Let's jump back in where we left off last week.
Multi-Leader Replication
Multi-leader replication, sometimes called leader-leader replication, involves the use of multiple primary nodes, also known as leaders, each capable of receiving and processing write requests. These leaders replicate data between each other to stay up to date. Each leader may also have follower replicas for read scaling.
The primary advantage of this model is increased write availability. With multiple active leaders, failure of one node doesn't disrupt writes - other leaders continue handling write requests. This improves upon leader-follower designs where a failed leader halts writes until a new leader is available.
However, multi-leader replication comes with its own set of challenges. For instance, with multiple leaders handling write requests, conflicting changes may occur when leaders modify the same data concurrently.
Managing Conflict
Conflicts are a natural outcome in multi-leader replication models given that multiple leaders can perform write operations simultaneously. Effective conflict management is a complex task, but it is crucial for ensuring data consistency and integrity.
Here are some commonly employed conflict resolution strategies.
Last Write Wins
This is a straightforward method where the most recent change takes precedence. While easy to implement, it risks discarding important updates.
Conflict-free Replicated Data Types (CRDTs)
CRDTs allow for seamless reconciliation of conflicting changes by merging them. CRDTs come in various types for different kinds of data like counters, sets, and lists, and automatically resolve conflicts without requiring a separate conflict resolution process.
Operational Transformation
Operational transformation is often used in real-time collaborative applications. It takes the operation itself into account, not just the state of the data. This method is complex to implement but offers fine-grained control.
Application-specific Resolution
In some cases, conflict resolution logic can be pushed to the application level. The application can employ domain-specific rules or even involve human intervention for resolving conflicts.
Data Partitioning
Another alternative is to partition data across multiple leaders to minimize conflicting changes. However, implementing cross-partition transactions requires careful coordination, and potential hot spots on busy data partitions need to be managed effectively. It’s worth noting that this strategy can reduce the overall write throughput across the cluster.
Replication Lag and Inconsistent Reads
As with leader-follower replication, multi-leader systems are susceptible to replication lag and inconsistent reads. They cause temporary inconsistencies between leaders until updates fully propagate. Applications must be designed with this in mind.
Use Cases
What are some use cases for multi-leader replication? For applications that have users globally, multi-leader replication can reduce the latency for end-users by allowing them to interact with a nearby leader node.
Systems that cannot afford downtime, such as financial transaction platforms, can benefit from having multiple leaders. Even if one goes down, operations continue.
For applications with heavy write loads, distributing the write operations across multiple leaders can prevent any single node from becoming a bottleneck.
Tradeoffs and Challenges
In essence, multi-leader replication is particularly useful for applications that prioritize high write availability, fault tolerance, and globally-distributed data accessibility. Many modern databases can leverage this replication strategy, either natively, or with an extension, with varying degrees of success.
Multi-leader replication provides high availability but requires careful design around consensus, conflict detection, and resolution mechanisms. When implemented well, it can be a powerful approach for maximizing write throughput and availability.
In the next section, we’ll explore the leaderless replication model which takes a different approach.
Leaderless Replication
Leaderless replication takes a quorum-based approach. This concept may sound a bit strange, especially when we've just spent some time discussing models that operate under a clear hierarchy. In a leaderless system, any node in the network has the authority to accept write operations. The absence of a single leader fundamentally changes the dynamics of our system.
Quorum Writes and Reads
Now, let's start with a key concept that underpins leaderless replication: 'quorum writes and reads'. In a system without a leader, we don't rely on any single node to validate a read or write operation. Instead, we aim for consensus among a certain number of nodes. This number is called the 'quorum'. Using a quorum approach balances high availability with data accuracy, since we no longer require full consensus across all nodes.
In this system, we use three important values.
'n' is the total number of nodes in our system.
'W', the write quorum, is the minimum number of nodes that need to agree for a write to be considered successful.
'r', the read quorum, is the minimum number of nodes that need to agree for a read to be valid.
For strong consistency, a general guideline is to have w + r > n. It ensures that any read overlaps with any write and returns the most recent value.
For example, imagine a system with 3 nodes (n=3). If we configure w to 2, that means we need two out of three nodes to acknowledge a write request before it is deemed successful. If one of the nodes went down, the write operations could still continue. This idea works similarly for reads. If r is set to 2, the read operation would query 2 nodes and return the most recent data between the two.

Corporate boards have a new mandate: Help companies build geopolitical resilience
On Point
Brought to you by Liz Hilton Segel, chief client officer and managing partner, global industry practices, & Homayoun Hatami, managing partner, global client capabilities
•
Rerouting supply chains with AI. Multinational companies with complex supply chains now have a new tool at their disposal: generative AI. In the face of ongoing geopolitical tensions and uneven economic recovery from the COVID-19 pandemic, companies are using generative AI to identify vulnerabilities and help them quickly connect with suppliers. Some countries now have regulations requiring monitoring of environmental and human rights issues, which can be identified through technology. While only about 14% of supply chain professionals currently use AI, a new survey shows that more than 90% plan to start. [FT]
•
Managing geopolitical risks. Recent McKinsey Global Institute research shows that global flows of data, exports, and talent remain strong; however, the world is also becoming more fragmented. While senior leaders know it’s important to navigate geopolitical risks, the role of corporate boards in doing so is not always clear. McKinsey senior partner Chris Leech and colleagues suggest steps directors can take to help them deal with larger-scale forces such as macroeconomic shocks and climate change. Reassessing a board’s composition to include diverse domain expertise and relevant experience and holding meetings in a range of markets to deepen a board’s understanding are first steps.
•
Building boards for today’s global order. A board composed of subject matter experts with clearly defined roles (for example, through a set of key committees) can help companies build resilience in supply chains and other areas. Dashboards that regularly review relevant markets can help boards gain clarity on critical developments and their effects. Learn how boards can adapt their monitoring and mitigation strategies for the fast-changing geopolitical landscape.

Delivery by drone may be landing on a porch near you

ON DRONE DELIVERIES
Drone deliveries are developing, but challenges remain
Robin RiedelYou might be startled if you looked out your window and saw a drone hovering near your door, about to release a package onto your front steps. But such a sight could become more common as companies ramp up the use of drones in making deliveries. In 2021, there were close to half a million commercial-drone-delivery flights globally, and that number grew to about 875,000 in 2022 (an average of almost 2,400 drone deliveries per day). In 2023, we expect drone deliveries to exceed the one-million mark.
The benefits of such trips go beyond quickly providing a lunch order or birthday gift. Delivery drones fly at an average speed of 30 to 60 miles per hour, which allows them to rush critical supplies to people in disaster zones and remote, inaccessible areas. In crowded urban areas, deliveries via air routes could ease traffic congestion. The environmental advantages are also clear: delivering a one-pound burrito with a drone that usually weighs between five to 25 pounds generates far less emissions than using an average car, which weighs about 4,100 pounds.
If the scale-up continues, as we expect, there could be many winners. Some skeptics might question our current growth projections, however, since companies thus far have made limited progress on their long-standing plans to increase drone delivery flights. So what recent developments are encouraging more optimism? And what challenges remain?
First, the positives. Investor interest in drone delivery opportunities is at an all-time high: funding reached $101 million in 2022 but has hit $770 million in just the first half of 2023. The technology has also advanced considerably; for example, drones can now accurately navigate during subpar conditions, such as rainstorms.
In another major shift, the time-consuming process of defining regulations has recently borne fruit. As of March 2023, at least seven major regulatory bodies had issued rules about commercial-drone operations, focusing on aircraft certification, operator certification, airspace and operating rules, and infrastructure. (Aerial platform drones—those used for inspections or other types of observation—have lower certification requirements, so they are already in more widespread use.) In the United States, the Federal Aviation Administration’s Beyond Visual Line-of-Sight Aviation Rulemaking Committee released a report in March 2022 that included some recommendations, still under review, that could facilitate multiple aspects of delivery drone operations, including pilot certification and repair and maintenance.“In 2023, we expect drone deliveries to exceed the one-million mark.”
Public opinion of drone deliveries has also warmed. In a McKinsey survey of over 4,600 consumers, 56 percent of respondents said that they would opt for drone delivery if it was faster than the alternatives and did not cost more. Further, in a recent survey of drone industry executives, respondents reported that they expected 60 percent of their end customers to return after the first use of drone services.
Now let’s look at the challenges ahead. Despite the uptick in consumer acceptance, many people still worry that delivery drones may generate too much noise, invade privacy, or simply interfere with their enjoyment of a scenic sunset by crisscrossing the sky. Publicizing the benefits of delivery drones, such as lower emissions, may win over some new adherents. Consumers may also become more supportive if they see how longer-range drones can increase equity by improving people’s access to critical products and services. For example, there is a start-up that delivers vaccines and medicines to over 2,000 hospitals in Ghana, Rwanda, and the United States. Once consumers become more aware of such services, they may become more tolerant of a drone’s buzzing.
Beyond winning over consumers, the drone industry must address some remaining regulatory and technological barriers. Currently, many countries allow operators to control only a single drone, and some also require visual observers for some parts of the flight. The resulting high labor costs make it challenging to scale flights. On the technology side, the industry could benefit from further improvements in batteries—to support longer flights—and in the detect-and-avoid systems that help drones navigate crowded areas.
Of course, drones have uses that extend far beyond delivery, and these applications are also advancing, maybe even at a faster rate. Many companies, for example, including a large furniture retailer, use drones in warehouses to take photographs of inventory, which they then analyze using artificial intelligence. Others monitor remote assets using aerial surveillance drones that can check for damage, eliminating the need for costly on-site visits. Outside the corporate sphere, drones have been incorporated into aerial firefighting, agricultural seeding, and wildlife management. Eventually, passenger drones may play a big role in transportation. Even though it’s still early in the game, the possibilities are endless within this exciting sector.ABOUT THE AUTHOR

Join me on Thursday for how to Master Software Remediation using New Relic Vulnerability Management
Hi MD,
It's Liam Hurrell, Manager of Customer Training at New Relic University, here. Do you feel like your regular security assessments come up with huge list of potential vulnerabilities that lack enough context to know which are real and what to fix first? Do you want to enhance your team's awareness and get actionable insights on how to mitigate all these threats? If so, you can register for the free online workshop that I'll be hosting on Thursday 7th September at 2 PM BST/ 3 PM CEST.
Applications today often consist of thousands of components, each with the potential to carry critical security vulnerabilities. Mitigating threats is no longer the sole responsibility of security teams, with a new shared responsibility between DevOps and Security teams (DevSecOps) to have a security mindset across the development pipeline. In this practical session, you’ll find out about how New Relic vulnerability management lets you see and fix security issues in one connected experience with zero configuration, open integrations, automatic risk prioritization, and alerting on newly discovered vulnerabilities across all teams (Dev, Ops, Sec).
You can find the full agenda on the registration page here. While we recommend attending the hands-on workshop live, you can also register to receive the recording.
Hope to see you then,
Liam HurrellManager, Customer TrainingNew Relic

If you’re feeling burned out, you’re not alone. How widespread is employee burnout?
On Point
Brought to you by Liz Hilton Segel, chief client officer and managing partner, global industry practices, & Homayoun Hatami, managing partner, global client capabilities
•
Burned out and unemployed. It’s not just full-time workers who are getting burned out: people looking for work are also on edge. Many may spend countless hours applying to jobs, networking, and interviewing—only to be rejected and end up having to start over. One careers expert advises job hunters to set aside a specific time every day to create job alerts, reply to emails, and submit applications. Establishing a routine can help to ease the mental burden of a lengthy job search, the expert adds. [BBC]
•
A worldwide challenge. When there’s a chronic imbalance between the demands of a job and the resources available to tackle them, workers may become depleted, cynical, and emotionally distant. Employee burnout is a widespread challenge. Between February and April 2022, McKinsey conducted a global survey of nearly 15,000 workers and 1,000 HR decision makers in 15 countries. On average, one in four employees surveyed reported experiencing symptoms of burnout, McKinsey partner Erica Coe and coauthors found.
•
Toxic work environments. In all 15 countries surveyed by McKinsey, toxic workplace behavior was the biggest predictor of burnout symptoms and intent to leave—by a large margin. Employees who report experiencing high levels of toxic behavior at work are almost eight times more likely than those who don’t to experience burnout symptoms, according to the 2022 survey. Explore our McKinsey Explainer to learn the steps employers can take to effectively target toxic workplace behavior and address employee burnout.

CEOs get one chance to make a good first impression. What does it take to transition well?
On Point
Brought to you by Liz Hilton Segel, chief client officer and managing partner, global industry practices, & Homayoun Hatami, managing partner, global client capabilities
•
A team effort. Even superstar CEOs can’t do it all alone: behind every great leader is a great team. To build a strong leadership team, a successful leader needs to consider which leadership team style is best for the company, its mission, and the CEO’s personality. For instance, the CEO could foster competition or cooperation among team members. By aligning on the leadership team’s purpose, outlining team structures, and deciding the right approach to dissent and decision making, executives can mold individuals into one team. [Fast Company]
•
A challenging transition. The CEO role is unique. As the face of the company and the ultimate integrator, the chief executive’s position comes with new responsibilities and stakeholders. So it’s no wonder that 90% of CEOs say they wish they had managed the transition differently, according to McKinsey senior partners Kurt Strovink and Carolyn Dewar. Dewar coleads McKinsey’s CEO excellence work and is a coauthor of the book CEO Excellence: The Six Mindsets That Distinguish the Best Leaders from the Rest.
•
Success from the start. In writing CEO Excellence, the McKinsey authors sat down with about 70 of the world’s best CEOs. More than two-thirds said that the role wasn’t what they had expected it to be, Dewar shares. Yet there is a profound opportunity for both personal and institutional renewal. Transitioning to a new CEO can “unfreeze” organizations, reaffirm what’s valuable about the culture, and innovate for the next chapter. For four elements of a successful CEO transition, listen to the full interview on our Inside the Strategy Room podcast series.

How does a Password Manager Work?
Implement passkey authentication in minutes (Sponsored)
Join TikTok, Paypal, Google, and other leading tech companies by giving your users a faster and more secure sign-in experience with passkeys. Building an in-house auth solution takes months and requires ongoing maintenance from security engineers. But there’s a better way. Passage by 1Password is a cross-platform, ready-to-ship passkey solution. ByteByteGo readers get an exclusive six-month free trial – just use the code ‘BYTEBYTEGO6MO’ once you sign up in the console.
Top 5 Most Used Architecture Patterns
OAuth 2.0 Flows
Authorization Code Flow: The most common OAuth flow. After user authentication, the client receives an authorization code and exchanges it for an access token and refresh token.
Client Credentials Flow: Designed for single-page applications. The access token is returned directly to the client without an intermediate authorization code.
Implicit Code Flow: Designed for single-page applications. The access token is returned directly to the client without an intermediate authorization code.
Resource Owner Password Grant Flow: Allows users to provide their username and password directly to the client, which then exchanges them for an access token.
Over to you - So which one do you think is something that you should use next in your application?Scale automated QA without overspending (Sponsored)
Most QA teams are too resource-constrained to maintain an automated end-to-end test suite for their entire product. But costs to scale QA are hard to justify. The end result? Gaps in test coverage and bugs shipped to production. Here's a cost-effective solution to get 80% automated test coverage in just 4 months.
QA Wolf is a new technology-enabled service that leverages Playwright to build end-to-end test suites. Plus, they include 24-hour maintenance (ask about their zero flake guarantee) and unlimited parallel runs on their Kubernetes infrastructure.
Current customers include Cohere, Gumroad, and Napster (and they boast a 4.8/5 rating on G2).
Understanding Database Types
To make the best decision for our projects, it is essential to understand the various types of databases available in the market. We need to consider key characteristics of different database types, including popular options for each, and compare their use cases.
Types of Software Engineers and Their Typically Required Skills
In this overview, we'll explore three key types of Software engineers:
Front-End Engineer:
Specializes in creating user interfaces using HTML, CSS, and JavaScript. They focus on ensuring that apps are visually appealing and user-friendly.Back-End Engineer:
Works on the server-side of web applications, managing data, business logic, and server infrastructure to ensure functionality, performance, and security.Full-Stack Engineer:
A versatile expert who combines the roles of Front-End and Back-End engineers, handling UI design, server-side tasks, databases, APIs, and ensuring seamless application integration. They cover the entire development spectrum from start to finish.
Over to you: Which type of software engineer resonates most with your interests and career aspirations?
How does a Password Manager such as 1Password or Lastpass work?
How does it keep our passwords safe?
The diagram below shows how a typical password manager works.
A password manager generates and stores passwords for us. We can use it via application, browser extension, or command line.
Not only does a password manager store passwords for individuals but also it supports password management for teams in small businesses and big enterprises.
Let’s go through the steps.
Step 1: When we sign up for a password manager, we enter our email address and set up an account password. The password manager generates a secret key for us. The 3 fields are used to generate MUK (Master Unlock Key) and SRP-X using the 2SKD algorithm. MUK is used to decrypt vaults that store our passwords. Note that the secret key is stored locally, and will not be sent to the password manager’s server side.
Step 2: The MUK generated in Step 1 is used to generate the encrypted MP key of the primary keyset.
Steps 3-5: The MP key is then used to generate a private key, which can be used to generate AES keys in other keysets. The private key is also used to generate the vault key. Vault stores a collection of items for us on the server side. The items can be passwords notes etc.
Step 6: The vault key is used to encrypt the items in the vault.
Because of the complex process, the password manager has no way to know the encrypted passwords. We only need to remember one account password, and the password manager will remember the rest.
