Defining Antifragility and the application on Organisation Design

The .com crisis of 2000, 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 by 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 resilience. 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.

Building Quantum Computers in the Netherlands

Being able to control individual quantum systems will cause a second quantum revolution, with quantum computing as the most radical innovation. Once you know how to build a quantum computer, it’s easier to understand the value chain that’s behind the desirable ‘quantum computing as a service’. And that’s essential to estimate when and how quantum computing will start adding value.

The value of personal data in an international perspective

In this track we have seen different aspects of the use of data in organisations and eco-systems, different ways of creating value from data, personal identities and personal data. We focus on personal data management in this summarizing talk and 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 16 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.

From Accidental Architects to Collaborative Architects

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.

Moving conversations, better solutions

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’ll 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.

How to get a grip on your microservices system using a service-mesh

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 introduce you to 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.

A low-code architecture for financial services. Good reasons, better challenges and best practices.

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.

Three angles will be presented:

  1. The good reasons for low-code are about the starting points, the principles and the nature of low-code.
  2. The better challenges are about combining four low-code platforms, organizing architectural governance and managing partners.
  3. The best practices are about API management, the role of business analysis and the importance of agile working

Leadership Skills Optional?

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.

The human in the Soluition

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

Site Reliability Engineering (SRE) in a Multi-cloud World

Google has been practicing Site Reliability Engineering (SRE) since the early 2000’s. Through published books and external talks Google has been sharing the concepts of its opinionated DevOps implementation publicly. Today, microservices based architectures are widely adopted and the need to run these services simultaneously in different environments is increasing. In this talk we will look at the impact of these trends on the implementation of SRE and how related challenges are overcome?

The Positive Side of Change Resistance

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.

Prerequisite for high adaptability and response speed is the ability to quantify coherence

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.

AI Operations – Using AI for your Ops

AI is now more and more used in many fields. From physical robots to chat bots, from fraud detection to speech synthesis. But did you know AI can also be very useful to optimize your operations? A simple error message usually is too high level for detailed follow-up. This is where AI can be used to automate more steps in your operations processes and make improvements. Sebastiaan will interview Eduardo using his own questions as well as questions from the audience.

How cognitive biases and ranking fosters an ineffective architecture and design

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.
