An Enterprise Design approach to leading change
Milan Guenther – President at Intersection Group

Government, healthcare, finance, big tech, you name it: enterprises run our world and enable human agency at scale. Facing crisis, loss of trust and disruption, they call out for our help. “Make us resilient”, they say.

But what if we aimed beyond the chase for survival? Can we design better enterprises, to be more useful for people, and more successful in creating positive outcomes?

Enterprise Design connects people-centric product and service innovation to the organisational and operational transformation required to deliver. Don’t worry, this is not about running another Design Thinking workshop.

Milan will introduce you to the Facets and Patterns of doing enterprise change by design. You’ll take away a toolset designed to help you tackle messy challenges, make sense of a dynamic environment, and collaboratively plot a way towards a future to thrive in ? building on the strengths of your enterprise.


Milan’s work is about design applied to the enterprise level. He is president of the Intersection Group and a co-founder of Enterprise Design Associates. He works with enterprises of all shapes and sizes to bring entrepreneurship to life: designing brands, products and organisations to be useful, and making them actually deliver. His first book Intersection introduces this Enterprise Design approach, and he has been co-organising a conference series of the same name since 2014. Milan also teaches Enterprise Design at the School of Management of Innovation at Sciences Po Paris.

Master or servant? Are we humans still ‘top dogs’ in this brave new world of massive IT?
Gerben Wierda – Lead Architect at APG

IT used to be just a tool. Humans created the tool and humans used the tool. But some fundamental changes are happening. First, the separation between humans andˇtheir IT is disappearing. Our IT is becoming more and more integrated in our behaviour and it is our behaviour is what defines what we are. We are becoming ‘mental cyborgs’. Second, the volume of IT is becoming so large that the balance between human behaviour and IT-behaviour is moving from the absolute dominance of human behaviour to something else. Something where the independent behaviour of IT systems becomes key to understanding what is happening in the world.

We are no longer the clear masters, we operate in a setting where our will and intentions are less and less instrumental in what happens day to day. IT makes change of organisations harder, not easier. IT, by being a gatekeeper between us and reality is starting to strongly influence what we believe or how we can be interacted with and even decides what happens. Our freedom and our security are no longer a purely physical things. What is going to happen with our long, position as apparent masters of our environment? And what should we do?


Gerben C. Th. Wierda M.Sc. MBA (1961) works as enterprise architect (current role: Lead Architect) for APG, which manages approximately 600 Billion Euro in assets for roughly 5 million participants in a number of Dutch collective pension funds. Before that he was (amongst other things) Lead Architect of the Judiciary in The Netherlands, Head of the forensic IT department of the Dutch Forensic Institute.

In his spare time he is an independent author of blogs (of which the central one is https://ea.rna.nl/) and books, based on real world experiences in complex enterprises (of himself or his network) and (very occasionally) gives advice or provides training/coaching. His books are Mastering ArchiMate (now in its fourth edition) and Chess and the Art of Enterprise Architecture.

Defining Antifragility and the application on Organisation Design
Edzo Botjes – Antifragility Architect at Xebia

Theme Resilient Organisations

The .com crisis of 2000, the financial crisis of 2008 and the COVID-19 crisis of 2020 show us the importance for organisations to become resilient or even antifragile to survive (unexpected) external stressors. Research states that the current VUCA world will expose enterprises to more and more stressors. Resilience is the way a system bounces back from impact by a stressor. Antifragile is the way a system improves from impact by a stressor. In his master thesis Edzo combines (1) literature research on resilience with (2) the antifragile attributes found in the literature and (3) variety engineering into one model, an Extended Antifragile Attribute List (EAAL). Enabling the leadership of an organisation to determine if the organisation should aim to be antifragile or to be a specific type of resilient. The presentation consists of the EAAL model, theory and practical application via an interactive discussion on how to recognize the context and how to adjust your behaviour as an architect.

How to get a grip on your microservices system using a service-mesh
Edwin van Wijk – Principal Software Architect  at Info Support, Microsoft MVP

Theme Resilient Systems

Many organizations are now building microservices based systems. But with the adoption of this architecture-style, the need arises for a good way to manage and monitor all the services and their traffic. To handle this, you can leverage what is called a service-mesh. In this session attendees will learn what a service-mesh is and how to implement one for a microservices based system using Kubernetes and Istio. Topics covered are: intelligent traffic-routing, canary releasing, testing resiliency using chaos-engineering and monitoring using several available telemetry dashboards.

The Positive Side of Change Resistance
Bard Papegaaij, Director at Transgrowth

Theme Soft Skills

Change almost always causes resistance. Change threatens our identity: the careful crafted narrative we tall ourselves to feel (relatively) safe and valued in our work environment. Our emotional system acts like a defensive shield against these threats like an immune system responds to pathogens entering our body. In this workshop participants are shown how this sub-conscious immune system works and how the negative force of resistance can be turned into a positive force for change. By practicing on themselves and each other, participants learn to recognise the symptoms of their own immunity to change at work. Using these insights they then practice ways to change the conversation from the content of the change to the nature of the resistance. This helps to remove the threat and instead see the change as an opportunity to strengthen one?s identity and personal narrative.

A low-code architecture for financial services. Good reasons, better challenges and best practices.
Alcedo Coenen, Enterprise Architect at International Card Services

Theme Top Technology Trends

International Card Services (part of ABN AMRO group) has realised a completely renewed IT landscape with an architecture of low-code platforms, enabling its credit card business to modernize and extend with other financial services. The choice for low-code is essential, based on business strategy and organisational principles more than technical principles. While many financial companies have chosen a way of high code, ICS has chosen for the low-code paradigm and wants to be a customer centric company. How that is working, both technical and organisational, will be the subject of this presentation.

Software Architecture for Scaleups
Sander Mak, Director Of Technology at Picnic Technologies

Theme Resilient Systems

As a start-up, you have only goal: iterate on your product until people fall in love with it. Code is king, and shipping fast and frequently is essential. Picnic has found its product-market fit and is now in a quite different phase: scaling up. Software architecture plays an important role in making this transition, but it requires a conscious change in mindset.

In this talk, we’ll look at how software architecture has become an explicit concern across our product teams, without impeding on their autonomy. Steering architecture without unnecessary centralization is a challenge we need to face head-on. Come and learn about our successes (and failures) in bringing software architecture to Picnic as a scale-up.

Moving conversations, better solutions
Maryse Meinen, Scrum master / agile coach at Practical Agile NL

Theme Soft skills

Asking better questions, pure listening and having authentic conversations starts with an open attitude and a desire to practice. Like any art conversing is something you develop by doing? We are what we repeatedly do. So we? Ill start awakening your true listener within with hands-on exercises. We will also excite your inner questioner and practice with types of questions that will sparkle conversations. All the while focussed on an open mindset and a readiness to shift perspectives.

Prerequisite for high adaptability and response speed is the ability to quantify coherence 
Roel Wagter – Enterprise Architect at Solventa 

Theme Resilient Systems 

There is a direct link between the level of coherence in an organization and its performance, including responsiveness and adaptability. Measuring ‘enterprise coherence governance’ has been applied annually in a number of companies since 2014. However, measuring coherence itself, as a result of ‘enterprise coherence governance’, was not yet an option. In collaboration with a PhD student from Radboud University Nijmegen, we have developed an artifact with which this is now possible. A first experiment with representatives of 10 organizations has recently been carried out. In this presentation we would like to discuss the content of the artifact, called the Enterprise Coherence index, and the results of the performed experiment.  

From Accidental Architects to Collaborative Architects
Evelyn van Kelle and Paul de Raaij – Strategic Software Delivery Consultant at Qxperts 

Theme Soft Skills / Resilient Organisations 

Michael Nygard famously said, “Team assignments are the first draft of the architecture” and Conway’s Law tells us this quote isn’t talking about any rubbish. As architecture follows the communication structure of the organisation the organisation design forms the starting point of any architecture. As a result, organisational designers such as HR departments and managers become accidental architects of the software, without any software design knowledge. Up to the Software Architect to work around that. In this workshop, we will dive into some organisational theory and problems we often see in organisations. After this short introduction, it is up to you to create your own position paper containing beliefs and actions to boost the collaboration between the architects and the organisational designers in your organisation. 


The value of personal data in an international perspective
Jurjen Braakhekke, Managing Advisor and Marlies Rikken, Advisor at InnoValor

Theme Data as an Asset 

In this talk we take an international perspective to personal data management. Over the last few years, MyData Global has developed into a strong community that want to empower individuals by improving their right to self-determination regarding their personal data. Within MyData Global the operator thematic working group has developed a reference model for personal data eco-systems and more than 27 operators have used this model to describe themselves, creating a growing understanding of the field. We will dive into this model and plot the different viewpoints as presented in the track on this model, indication the way they can be united and how they reinforce one another. 

EA artifacts facilitating digital transformations’ strategic planning process
Frank Grave – Open University

Theme Resilient Organisations 

The exploitation of new value propositions enabled by disruptive digital technologies—also known as digital transformations—influences firms’ configurations of people, processes, and technology and must be considered in the enterprise’s strategy. Strategy planning, i.e., the process that determines strategy, is facilitated by enterprise architecture (EA). Hence, strategic plans are reflected in EA documents called artifacts. An explorative multiple case study in the financial services sector shows a fragmented implementation of EA artifacts, with each organization having established its own almost unique way of using EA artifacts. 

Battle for the Boardroom
Ronald Baan – President Data Management Association Dutch Chapter (DAMA NL) 

Theme Data as an Asset 

Data-driven working sounds like something we should want, let our decisions be guided by objective data. What do we need to make that work? How do we position data management and a CDO in our organization? Is the CDO a threat to the CIO or does it fill in a part of the responsibility of the CIO? How important is data management actually for data-driven working and can it not simply be set up per IT system? 

The human in the Solution
Annelore Luning, Enterprise Solutions Architect and Eltjo Poort, Vice President, Consulting Expert at CGI 

Theme Resilient Organisations 

Understanding the human context of a solution still appears to be one of the hardest nuts to crack in architectural design. We bring anecdotal and quantified evidence of this problem, and discuss the growing number of tools architects have available to help us solve it. We will discuss our experiences with tools such as empathy maps, personas and storytelling, and compare them with the audience’s lessons learned. After the workshop you will be familiar with ways to manage the human side of architectural design.

Then join this talk of the NAF focusgroep Industry 4.0! 


How cognitive biases and ranking fosters an ineffective architecture and design
Kenny Baas-Schwegler and Evelyn van Kelle – Strategic Software Delivery Consultants at Qxperts 

Theme Soft Skills

The power of collaborative modelling comes from having a diverse group of people who, together, have a lot of wisdom and knowledge. You would expect that all this knowledge will be put to use, co-creating, and to design a model. In reality, we don’t actually listen to all the available input and perspectives due to cognitive biases and ranking. Because not everything that needs to be said has been said, we will end up with sub-optimal models and architecture. Even worse, people don’t feel part of the solution and don’t commit to it. Good architecture and design need all the insights and perception. If you are not aware, cognitive biases and ranking kills those insights and kills the effectiveness of your architecture! We will let you leave this talk with how being aware of cognitive bias and how Deep Democracy the lewis method can really let the group say what needs to be said and take a collective autocratic decision in architecture and designing your software. 



Leadership Skills Optional?
Thijmen de Gooijer – IT Architect at Kommuninvest of Sweden,
Matthias Kittner – Head of Software Architecture and DevOps at ESI Group

Theme Resilient Organisations 

Architecture job descriptions often focus on technical skills, and we agree that these are important. However, delivering an architectural vision, requires the architect to ride the elevator between the boardroom and the “engine room”, and to influence different people and cultures, but often without formal power. Yet, we observe controversy about the role of soft skills in software architecture. This limits our development and the growth of new talent. During this open space workshop we will together explore the architect’s social role: why is there controversy on the role of soft skills; what leadership skills do we need; what skills are specific to our profession; and how do (future) architects learn and develop these skills. We will learn from each other and document thoughts that will help us grow ourselves and the next generation of great architects. 



Building a sustainable tomorrow – Smart buildings & infrastructure
Sander Meijer – Lead Enterprise Architect at BAM 

Theme Top Technology Trends 

BAM, the largest builder in the Netherlands, focuses on the increasing demand for sustainable and smart solutions in the Netherlands, the United Kingdom and Ireland. In these markets, BAM aims to further develop solutions throughout the entire life cycle by providing clients with innovative and sustainable solutions for design, development, implementation, maintenance and facility management. This also involves offering energy- and climate-neutral concepts and the roll-out of sustainable energy solutions for offices, homes and infrastructure.

By extracting data from assets, such as buildings, roads, bridges, and analyzing them using artificial intelligence, we can turn them into a digital twin and better understand the assets. We use artificial intelligence to simulate the future and now see what awaits an asset and what we need to do to ensure that the assets fulfill their function optimally. Using IoT, we allow assets to communicate with our back office, with other assets and with vehicles, and their combined data flows lead to new insights and opportunities for optimization. We offer these insights to our clients, tenants, homeowners and others. With the help of augmented reality and, for example the Hololens, we make it easier for our employees to carry out project and maintenance work. This technology also helps with the sale of homes by simulating what the future home will look like for the owner.

We also apply modern technology in our back office processing, such as RPA, and we use low-code technology to develop Apps. In addition, we use modern technology to support data-driven working and the aforementioned smart applications. For example, we recently implemented a Lakehouse with Microsoft technology.

These developments are increasing our dependence on IT. This also means that we are increasingly involved in business continuity, disaster recovery and cyber security. It means that we design, implement and manage the IT infrastructure, applications and data in a robust manner. During the Covid pandemic we demonstrated that we succeed in this.

As Lead Enterprise Architect and manager, Dr. Sander Meijer has been responsible for BAM’s enterprise architecture since 2017. Together with business and IT leaders, the enterprise architecture team translates the requirements for digital and data-driven working into modern and secure IT infrastructures, applications and data architectures.
Sander has over 20 years of experience in management, IT and enterprise architecture. He studied computer science and obtained his doctorate in business administration from Erasmus University Rotterdam.

From Bit to Qubit – an introduction to quantum technology
Ingrid Romijn – Division Coordinator at QuTech 


Quantum technology is based on the principles of quantum mechanics, describing the world of the smallest particles and their interactions. Major breakthroughs in the last decades allow us to use and manipulate these interactions in radical new applications of quantum computing, quantum networking and quantum sensing.
For example, quantum computers will have the potential to solve certain problems much more quickly than could ever be achieved using conventional computers. With quantum communication the security of information exchange can be enhanced by making message interception almost impossible – if anyone were to try, it would be immediately apparent to the sender and the recipient.  

What are potential uses of this technology, and what are the timelines associated to them? What could be the impact? Should companies already prepare for this emerging technology?  

In this session a short introduction on this novel technology will be given, and the questions above will be discussed. 

Dr. Ingrid Romijn is Division Coordinator in the Quantum Internet Division at QuTech. Ingrid was part of the team to create and write the Dutch National Agenda for Quantum Technology, and is currently program manager in the Quantum Delta NL foundation. 



Transcend the cloud: How cloud-native thinking paves the way
Cornell Knulst – Principal Consultant / IT Strategy Consultant @ Info Support

As cloud has the opportunity of being a digital discriminator, we noticed that not all organizations leverage the full potential of cloud. As there is a difference between doing agile and being agile, the same goes for cloud.

Over the past few years we guided several organizations in their cloud journey. We’ve seen that there is already a lot to gain from the first steps into the cloud.

But how to ensure that your organization really reaps the benefits and transcends the cloud? How to ensure cost efficiency, compliance, security and resiliency by design and during run? 

We think it starts with a cloud-native mindset. In this session we guide you through several real-world customer cases and show you how making the shift towards cloud-native execution will pave the way towards transcending expectations with cloud.

KLM rapidly scales up customer service during the start of the pandemic
Veronique van Houwelingen – KLM

During the beginning of the pandemic KLM and Air France had 10x more social media cases than normal. We will explain you during this session how we implemented a customer centric prioritization model.
