AI Leadership

The cases.

59 cases from CDayZ 2026 and the book written around it: the ones worked at the tables in Zadar, the participants' own dilemmas, and the cases written for the book. Each opens in Codex Mercatorum with its questions, the rounds of answers and the NEO Turn.

Tuesday 6 October — Art of Intelligence

The first day at the tables, in the Providur's Palace.

  1. 60

    The Encyclical Magnifica Humanitas

    11:00–13:00 · Magnifica humanitas · Lead: Dražen Kapusta

    On 15 May 2026, one hundred and thirty-five years to the day after Rerum novarum, Pope Leo XIV signed Magnifica humanitas, an encyclical on safeguarding the human person in the time of artificial intelligence.

  2. 03

    CEO Fire Chat

    15:00–16:00 · CEOs — a fireside chat, not a case · Lead: Iva Kapusta

  3. 02

    The Gold Medal the Model Did Not Win

    16:00–17:00 · Peak performance · Lead: Dražen Kapusta

    Sara Beram won a gold medal at the Mediterranean Games. Behind that moment were years of training, coaching, mental preparation, discipline, and continuous analysis of her performance. AI also became part of that process. Her coach used fight footage and AI-supported analysis to review rounds, identify patterns, and ask better questions.

  4. 08

    75% Data Problem, €250 Billion Opportunity, Fog, Solution

    17:00–18:00 · 8ra / IPCEI-CIS · Lead: Dražen Kapusta

    Europe is facing a major digital challenge. By 2030, the EU wants 75% of European businesses to use cloud-edge technologies. At the same time, more than 70% of Europe’s cloud market is currently served by the three largest American providers.

Wednesday 7 October — Art of Trade

Security, robots, hotels and the AI office.

  1. 33

    AI for Security and Business

    10:00–11:00 · Security & business — the peak-season week · Lead: Gordan Akrap

    Imagine you are the CEO of a family-owned food company during the most important week of the year. For six weeks, an attacker has quietly been inside your company. It began with a convincing supplier email.

  2. 05

    Imagine Robots in Business Three Years from Now

    11:00–12:00 · Robots · Lead: Iva Kapusta

    Imagine a warehouse in 2029. It is highly automated. Robots move goods, AI analyses operations, and different technology providers manage different parts of the process. At 2:17 in the morning, two robots stop in front of the same loading area.

  3. 21

    The Meeting Where Everyone Was Right and Nothing Moved

    12:00–13:00 · New CEOs · Lead: Srđan Jovanović

    At 11:47, the CEO realised they were having the same meeting for the fourth time. The slides were new. The arguments were familiar. The commercial director wanted to enter a neighbouring market while an important customer was willing to open doors. The finance director wanted stronger evidence that the expansion could pay for itself.

  4. 14

    AI Office

    15:00–16:00 · AI founders & systems · Lead: Tali Režun

    Imagine a company where employees have been experimenting with AI individually for months. Some use it for research. Others draft emails or automate routine tasks. One five-person team decides to redesign an entire workflow.

  5. 12

    Problem, Solution. All the Rest Is Noise

    16:00–17:00 · Command · Lead: Snežana Ilić

    Imagine a company where most meetings last ten minutes. The person responsible states the problem in one sentence. The team considers no more than three options. A decision is made, ownership is assigned, and the team agrees when to review the outcome.

Thursday 8 October — Art of Leadership (I)

At Hotel Hyatt: AI in the firm, the expert and the agent, the board, the hackathon.

  1. 13

    The AI Everyone Used but Underperformed

    10:00–11:00 · AI in the firm · Lead: Dražen Kapusta

    Imagine a company where almost everyone already uses AI. Sales writes proposals faster. Marketing creates more content. Finance analyses data instantly. Managers arrive with polished presentations. Every department has an AI success story.

  2. 15

    The Best Person for the Old Job Was Ready for the New One

    11:00–12:00 · Agents & governance · Lead: Snežana Ilić

    Imagine an employee everyone calls when something goes wrong. For twelve years, Martin has become indispensable. He knows customers, systems, exceptions, and difficult situations better than anyone else.

  3. 16

    The Board Pack Was Perfect. The Decision Was Not.

    12:00–13:00 · Boards · Lead: Luka Gauta

    Imagine a board considering the acquisition of a successful competitor. Everything looks convincing. Strong customers. Excellent financial model. Promising synergies. AI has helped analyse documents and prepare answers to every expected board question.

  4. 09

    The Sale That Happened Before the Meeting

    15:00–16:00 · Retail & brands · Lead: Saša Pavlaković

    Imagine a sales director preparing for the most important meeting of the quarter. Twenty-four slides. Product demonstrations. Customer references. Seven minutes into the meeting, the customer interrupts.

  5. 11

    The Executive Who Built Twice

    16:00–17:00 · Built twice · Lead: Irena Grofelnik

    For years, we treated executive leadership and entrepreneurship as opposite career paths. One represents governance, responsibility, and organisations. The other represents ownership, speed, and risk.

  6. 18

    The Hackathon Where Nobody Wrote Code

    17:00–17:30 · AI Hackathon · Lead: Dražen Kapusta

    Imagine a traditional manufacturing company invited to an AI hackathon. The sales director laughs. “We have no developers. What are we going to hack?” But nobody writes code. Each company provides only two sentences.

Friday 9 October — Art of Leadership (II)

The new roles of leaders, from Lex Mercatoria to the AI economy, and the tribe.

  1. 31

    Three Titles Arrived Before the Job Did

    10:00–11:00 · The school — a new role for its alumni · Lead: Aco Momčilović

    Marta had three proposals on her desk and one MBA diploma on the wall behind her. Lamora offered a Chief Transformation Navigator, two Navigators and a Navigation Analyst. Beutiful offered a Head of Applied Intelligence Experience whose experience, on closer reading, was eleven months.

  2. 10

    The First Monday as CEO

    11:00–12:00 · New CEOs · Lead: Vlatka Šrajbek

    Imagine it is your first Monday as CEO. On Friday everyone congratulated you. By Monday morning, everyone needs something. Pricing approval. Cost decisions. HR issues. Board questions. Suppliers calling.

  3. 06

    From Lex Mercatoria to the AI Economy

    12:00–13:00 · Chambers · Lead: Dražen Kapusta

    Imagine two companies doing business across borders. AI agents help exchange offers, specifications, and delivery details. The buyer sends an updated specification. The supplier’s AI agent acknowledges receiving it.

  4. 23

    Do You Need a Tribe in the NEO Era?

    15:00–16:00 · Universities · Lead: Zrinko Petener

    Think about the people you studied or worked with during the most intense period of your career. You saw each other under pressure. You worked late. You disagreed. You watched each other solve difficult problems.

  5. 24

    The Trip They Still Talked About Years Later

    16:00–17:00 · Pharma & healthcare · Lead: Ivana Babić

    Five years after a learning journey, someone posts an old photograph. Within minutes, people begin remembering conversations rather than presentations. Getting lost on the way to a meeting. Dinner discussions.

Friday 9 October — the closing session

The Zadar Declaration and the closing session.

  1. 25

    The Zadar Declaration and the Closing Session

    17:00–17:30 · The closing session — everyone who stays to the end · Lead: Iva Kapusta

    For more than twenty years, COTRUGLI has worked with thousands of executives, entrepreneurs, and leaders. Over time, certain patterns become visible. The most successful people are not always the smartest.

Cases from the MBA and the Vanguard

Real dilemmas from the participants' own firms, signed with a code, each with the mentors' rounds.

  1. 35

    Who Should Own the Intelligence?

    MBA module — a startup deciding whether to buy AI capability or build it · A participant's case · MBA-A1

    We have already launched an AI-powered platform designed to help smallholder farmers turn raw farm data into actionable insights. The platform collects information from farmers about their farms, crops, soil, farming practices, and field conditions.

  2. 36

    Who Owns the AI?

    MBA module — the inventory that showed four AI environments · A participant's case · MBA-S1

    On Monday morning, Elena received what looked like a simple request. Her organisation had been asked to prepare an inventory of the artificial intelligence systems it used: the name of each system, its purpose, the type of data involved, and who was responsible for it.

  3. 38

    Before You Enter the Room

    MBA module — preparing the argument, or preparing the room · A participant's case · VanguardJ1

    A few months ago, our organization was considering how best to structure a managed services organization supporting customers across multiple countries and regions. At a high level, there were two competing approaches.

  4. 39

    The Leader the Operation Could Not Afford to Lose

    MBA module — when operational stability begins to depend on one person · A participant's case · MBA-S2

    The operation was finally stable. That was when he started to think he had created a new problem. At one point in his career he had taken responsibility for a high-volume operation run by a large international company.

  5. 40

    Nobody Changed on Monday

    MBA module — when a training budget changes nothing on Monday · A participant's case · MBA-S3

    The company sells heating systems — boilers, and increasingly heat pumps — in one small European market. It is the national sales arm of a large German manufacturer: €30 million in revenue, €9 million in gross profit, around fifty people, no factory. Everything it sells reaches the end customer through installers and wholesalers.

  6. 41

    The Algorithmic Bench: Who Owns standard of care in Autonomous Diagnostic Triage?

    MBA module — who owns the standard of care when triage is automated · A participant's case · VanguardJ2

    The emergency department at Jane General Hospital System was operating at 140% capacity when the executive committee deployed Aegis-Triage, an advanced AI decision-support agent designed to prioritize incoming critical patients.

  7. 42

    The Stadium That Drank the Water

    MBA module — prestige or water, when the decision is already political · A participant's case · VanguardG1

    In a semi-arid county in East Africa, the decision has already been taken in private. The county government, supported by the national political leadership, is about to break ground on a multi-purpose stadium. The budget is approximately KES 20 billion.

  8. 43

    The Line at the Bottom of the Email

    MBA module — when telling the customer it was the AI costs a third of the meetings · A participant's case · MBA-L1

    The test was meant to be routine. By Thursday it was the most uncomfortable slide in the commercial review. Eight months earlier, the company had rolled out an AI agent to its outbound team.

  9. 44

    Who Understands the Code?

    MBA module — faster software, or developers who still understand it · A participant's case · MBA-D1

    A small software company develops a specialised platform used by customers around the world. The company has a close technical team: eight developers work on new features and improve the software, while six engineers provide global support to customers.

  10. 46

    The Sentence That Decided Nothing

    MBA module — when "equally important" becomes a number (a European telco) · A participant's case · MBA-A2

    “The router loses the signal every evening. I pay for the fastest package, and my children do their homework on mobile data.” It was one of several thousand comments in the February customer survey. The company’s AI analytics system had read all of them overnight and linked the complaints to equipment age, acquisition channel and churn.

  11. 47

    The Cognitive Atrophy Dilemma

    MBA module — when intelligence becomes abundant, should leaders protect the human ability to think? · A participant's case · MBA-T1

    For most of human history, progress has followed a simple pattern. We created tools to reduce physical effort. The wheel reduced carrying. The engine reduced walking. The crane reduced lifting. Every major technological breakthrough allowed people to do more work with less exertion. No one worries today that forklifts made humans weaker.

  12. 48

    Accountability Without Authority

    MBA module — when responsibility expands faster than mandate, recognition and executive ownership · A participant's case · MBA-M1

    Daniel was a middle manager in the finance function of a large company operating in a volatile and demanding market. Formally, his role was to manage a team, ensure that the department delivered its operational responsibilities, and provide expert support in financing, liquidity management and financial risk.

  13. 49

    Who Chooses the Next 240?

    MBA module — using AI to select young innovators when the deadline is faster than the people · A participant's case · VanguardD1

    I coordinate programmes for a pan-African network of university innovation hubs, supported by a UN agency. There are 23 hubs in 21 African countries, with five more opening by December. Many of the students and young founders who come through our hubs have never had access to serious training, mentors or funding.

  14. 50

    The Manager Who Was Faster Than Everyone

    MBA module — when AI makes one leader look like ten · A participant's case · MBA-A3

    The first sign that something had changed was not the quality of the work. It was the speed. Within three months, one middle manager had become impossible to keep up with. He answered emails within minutes, produced meeting summaries before anyone else had finished processing the meeting, and delivered polished presentations overnight.

  15. 51

    The Robot That Came First

    MBA module — when technology arrives before volume, capability and proof · A participant's case · MBA-A4

    The first meeting was supposed to be about a robot. Within an hour, it became a conversation about what kind of hospital the customer intended to become. The hospital was privately owned, financially strong and already well known in several areas of medicine.

  16. 52

    The Automation That Failed Because It Worked

    MBA module — fix the exception or change the process, when one customer journey crosses two companies · A participant's case · MBA-B1

    The process was quite simple. When a customer had an insurance claim and the insurer needed photographs, an employee entered the claim into InScope and sent the customer a link. The customer opened the link, followed the instructions and took the required photographs.

  17. 53

    The Veto Nobody Wanted to Call

    MBA module — when the final veto teaches people to bring problems late (a small pharmaceutical company) · A participant's case · MBA-G1

    I run the Quality Assurance and Control Department at a small pharmaceutical company. We distribute medicines and medical devices, and we operate a small manufacturing line. Around 120 people work here across office, warehouse, and production floors, and everyone knows everyone by first name.

  18. 54

    The Standard in Her Head

    MBA module — when a brand's standard lives in its founder's head and the first big order tests it · A participant's case · VanguardS1

    The order was one the brand had been working toward for three years. A regional retailer wanted a collection of naturally dyed, eco-printed garments, ten times the brand's usual monthly volume, with a second order to follow if the first went well and possibly getting another retailer on board.

  19. 55

    From Alarm to Action

    MBA module — how far a 24/7 NOC should trust an AI Co-Pilot in a live incident · A participant's case · MBA-V1

    02:17. The night shift in a telecom Network Operations Center sees three BTS/cell-unavailable alarms appear in the RAN monitoring tool. Three sites are not unusual enough, by themselves, to explain the cause. They could be unrelated local failures. They could be power. They could be transport.

  20. 56

    The Architect Who Became the Bottleneck

    MBA module — when a small practice's quality still runs through the founder's desk · A participant's case · MBA-H1

    I have run my architecture practice for thirteen years. It is a small office, and that has always been part of its strength. Clients know who is responsible. Decisions can be made quickly. I know the history behind every important drawing, every conversation with a consultant, and every promise made to an investor.

  21. 57

    The Dashboard Nobody Asked For

    MBA module — when the best tool in the division is the one nobody approved · A participant's case · MBA-N2

    It is the last week of the month, and Alex is doing what he has done every month since he joined: preparing the billing reconciliations for the corporate print fleets his manager is responsible for. He is a junior billing assistant in the managed print division of a large IT group.

  22. 58

    Everyone's Initiative, Nobody's Decision

    MBA module — when a flat organisation sends every decision to the same six people · A participant's case · MBA-J1

    A fictional leadership case for discussion. The managing director had built the branch himself. When he arrived in Zagreb, the local office of the international group had twenty people and one large customer. Eight years later, it had eighty-five people, a strong regional reputation and some of the best engagement scores in the group.

  23. 59

    The Control That Never Sleeps

    MBA module — when AI becomes the bank's primary checker (a Southeast European bank) · A participant's case · MBA-P1

    For years, the final check before a loan is disbursed has looked much the same.

  24. 61

    The Companies That Never Knock

    MBA module — the innovation hub that waits for small firms to ask (a European Digital Innovation Hub) · Lead: Tomislav Plesec

    The services were ready. The AI experts were available. The European funding was in place. Companies could receive support, training and access to advanced digital expertise at little or no direct cost.

The MBA module

The cases of the Vanguard Leadership MBA module.

  1. 29

    The Night the Titles Came Off

    Community (the Friday eXperience) · Lead: Petra Kosić

    At half past ten, the regional CEO was helping move a table. An entrepreneur held the other end. A younger manager cleared a path while someone rescued three glasses from the edge. They had spent the afternoon discussing leadership in a room where their names and positions appeared on a screen.

  2. 30

    Learning Together, Building Together — Stronger Together

    Family firms · Lead: Irena Grofelnik

    At the end of the first module, they compared notes on the journey home. They had listened to the same faculty, discussed the same case and spent the weekend with the same generation. Their notebooks looked surprisingly different.

Beyond the four days — cases for the book

Cases written for the book, outside the programme.

  1. 04

    Why Smart People Still Produce Weak Decisions

    Intelligence

    The meeting began on time, which made it look disciplined. The agenda was clear. The slides had been sent the evening before. Finance had prepared numbers. Sales had brought market signals. HR had employee concerns. Operations had capacity constraints. Marketing had customer data.

  2. 07

    The Season Was Full, but the Destination Wanted More

    Hotels & tourism

    Imagine you are a hotel owner after a successful summer season. The hotel is full, guests are happy, and one guest asks: “We would love to come back in November. Could someone organise the whole stay for us?”

  3. 17

    The Rail That Never Decides

    AI Act — lawyers & advisors

    Imagine your largest customer suddenly withholds €62,400 from an invoice. They claim your delivery was late and your product failed to meet specification. Your company disagrees. Normally this would become weeks of emails, lawyers, and conflicting memories.

  4. 19

    The Job Nobody Could Hire For

    HR

    The eighth candidate withdrew on a Thursday. The founder read the recruiter’s message twice. “She likes the company and the team. Her concern is the scope of the role.” The position had been open for four months.

  5. 20

    The European Company That Finally Raised Its Ambition

    Europe — the big-name hour

    The invitation arrived through a customer they already served. A European industrial group was preparing a common operating programme across several countries. Its procurement team wanted to know whether the company could support the wider organisation.

  6. 22

    The Customers Who Stopped Buying and Started Belonging

    Marketing & media

    The founder arrived at her own customer event and found that nobody needed her to open it. At one table, an experienced customer was helping a newcomer adapt a template. Across the room, two people compared how they had introduced the company’s product to their teams.

  7. 26

    The Infrastructure That Changed Sides

    Energy

    The disaster-recovery plan was excellent. It had been audited twice. It failed in an afternoon — not because anything in it broke, but because the world it assumed stopped existing.

  8. 27

    The Invoice Nobody Wanted to Send

    CFOs

    The invoice had been ready for eleven days. Nobody had sent it. He found it on a Monday, in the shared folder, numbered and complete: the second milestone on a custom test line for a large manufacturer, 184,000, the biggest single line his engineering firm had ever written.

  9. 28

    The Deadline That Was Not the Clock

    B2B & the region

    --- The deadline arrived before the offer did. On a Tuesday morning the CEO of a precision-components manufacturer in a small Central European country — 340 people, one plant, a reputation built over nineteen years — received a two-line message from the procurement lead of a large infrastructure group in the Gulf.

  10. 32

    The Sky Had No Border. The Data Did.

    One Sky — the cross-border low-altitude corridor

    In 2031, the distance between Shenzhen and Hong Kong had not changed. The meaning of that distance had. Thousands of autonomous aircraft now moved through the low-altitude layer above the Greater Bay Area.

  11. 34

    Sales Owned the Result. No One Owned the Whole.

    Organizational coherence — when formal authority is not enough to govern the whole · Lead: Irena Grofelnik

    At the end of a business-process review, the CEO heard two competing explanations for the same commercial problem. The process consultant's diagnosis was direct: the problem did not sit in sales alone. It ran through procurement, logistics, inventory and sales.

  12. 37

    The Hour Before the Decision

    Security, performance and command — the reserve case

    The exercise begins at 04:40, and the first thing that fails is not a machine. Twenty-two people are in the room: eleven officers on a command course and eleven executives who were invited because the academy wanted to see what happens when the two groups are given the same problem. A port matters to both of them.
