35 years ago, Eliyahu Goldratt introduced the Theory of Constraints (ToC) in his seminal book "The Goal" as a new management paradigm for manufacturing plants, struggling with excess inventory, late deliveries, poor quality. The ToC solved this through five focusing steps - a guideline to systematic improvement and continuous learning.

Today, the ToC is one of the pillars of the DevOps movement. This talk will present its principles, and how it applies to the software industry, through a mix of…

This talk will provide insights for a successful integration of lean-quality management to scaled agile projects. We will show based on our project experience that by improving process quality, higher product quality is achieved, resulting in significantly increased customer satisfaction. We will share how the lean principles and an easy-to-use toolkit helped us to tackle complex problems by providing a proven and scalable approach for continuous improvement and boost business agility at the…

This workshop gives a short introduction to BOSSA nova (Beyond Budgeting, Open Space, Sociocracy and Agile combined to support company-wide agility), but is mainly very interactive, supported by various Liberating Structures.

It helps the participants to identify and refine their biggest challenges in the agile transformation in their organization and provides a structure in which they can create and improve a probe that they can start with when back in office.

A practical workshop for…

If you’re not making mistakes, you have no chance to learn enough! This is especially true in complex situations, where, more often than not, the difference between a success and a failure can only be seen in hindsight. Which is why it pays off to dare new things, even if that might mean you can go wrong–as long as you don’t make the same mistake twice!

In this interactive talk we will explore how psychological safety, creativity, complexity and motivation are connected. And we will exercise our…

When facilitating retrospectives, there is often a focus on the agenda, the activities and the experiments you take away from the retrospective. Also, there might be a technical theme for the retrospective, but the people and the process for cooperation and communication is often what you end up discussing.

I will provide you with tips and tricks for how to avoid neglecting the human aspect of your retrospectives; the trust, the different personality types, the feeling of safety, and what you can…

The growth of Kafka inside an organization sometimes follows the development of the broader Kafka ecosystem over its lifetime. The initial use case may be something conceptually simple, like mainframe offload or point-to-point integration, evoking the simple Large Pipe architectures of Kafka’s infancy. Then those newly populated streams of events present themselves as fertile grounds for real-time analytics, as stream processing applications grow up around them to perform analysis…

How much can you separate what you are building from how you are building it? This becomes an increasingly relevant question with IT moving from building systems to cultivating ecosystems. At the enterprise architecture level, one of the challenges nowadays is to decide which constraints to put in place to get a robust and evolvable landscape of interacting components, while at the same time it is important to minimize these constraints so that teams and units have some autonomy, and that the…

The Extended Business Model Canvas (EBMC) links Lean Portfolio Management, System Thinking, Lean Product development, and agile development in a way suitable for established enterprises, not just startups.

Two additional components, the "Contribution to Strategy" and "Technical Debt," apply now to both operational and development values. Those components are supported by two special lenses that help agile teams to connect better, align, and achieve more business agility.

Target Audience:…

80% of machine learning is said to be data wrangling. Is all this wasted effort? Hardly - often the journey really is its own reward.

In this talk, we'll briefly describe a machine learning project that predicts the outcome of test cases in a large-scale software development cycle. We'll then show what we gained from collecting the necessary data and how these insights can have lasting impact on the day-to-day work of developers, testers and architects. This includes a quick answer to the…

In speaking about better ways of thinking and problem-solving, Linda has introduced Jonathan Haidt's model for the brain. He proposes that the rational, conscious mind is like the rider of an elephant (the emotional, unconscious mind) who directs the animal to follow a path. In Fearless Change, the pattern Easier Path recommends making life easier to encourage reluctant individuals to adopt a new idea. Linda suggests that in conversations with others who see the world differently, we "talk to…

SOLID principles are well-known for designing object-oriented systems. But what if you are developing microservices? IDEALS, is yet another silly mnemonic acronym and are the core principles for microservice design. The acronym stands for: Interface segregation, Deployability, Event-driven, Availability over consistency, Low Coupling, and Single responsibility. We will relate these IDEALS to techniques, tools, technologies, and domain modeling principles we use today to develop modern…

Apache Kafka became the de facto standard for microservice architectures. Decoupled applications and Domain-driven Design (DDD) are key benefits. However, that also introduces new challenges like observability of the whole ecosystem. This session explores the problems of distributed Microservices communication and how Kafka, Kubernetes and a Service Mesh like Istio address them. Learn some approaches for combining them to build a reliable and scalable microservice architecture with decoupled and…

Together with 100 IT engineers we have been given the freedom to figure out how to transform from doing traditional IT Operations to being agile.

We use Scrum@Scale and Heart of Agile to remove debt; Organizational Debt in the form of old leadership structures that create unclear mandate for scrum roles and prevents organizing around products; Technical Debt that keeps us busy maintaining old technologies and prevents the creation of relevant cloud infrastructure products.

Our story is about how…

As architects become more senior, we are expected to contribute to growing the product, the organization, and the people. This session explores three roles of an architect that help them meet these expectations: architect as leader, as mentor, as coach. This session offers practical tools, methods, and frameworks that help both experienced and aspiring architects succeed in each of these roles.

Target Audience: Architects, engineers, developers, managers, senior/principal/distinguished engineers

Architecture work is all about trade-offs. We weigh security against ease of use, we balance availability with maintainability and contrast performance with reliability. But how do we evaluate the cost and benefits of change? As architecture is a means to an end, not an end in itself, architectural improvements have to be governed by sound reasoning, and more often than not that has to be based on numbers. Which in turn implies the need for good practices for the financial evaluation of…

We took advantage of the COVID digitalization challenge and converted our Design Sprints and UX workshops into a digital format. A dozen customer workshops in a wide variety of contexts (including logistics, public and chemical clients) have demonstrated UX workshops can also work virtualized with some advantages, e.g. being able to integrate participants from remote locations cost-effectively. In this session evaluated tools, techniques, best practices and lessons learned virtualizing UX…

In an ever increasing need of remote work, we still need to envision new business models, explore our business processes and design our software systems. While nothing can replace the in person collaboration of an EventStorming, remote tools bring their own exciting upsides. During the lock down of the COVID-19 pandemic the DDD community experimented and distilled a collection of remote modelling methods. Let us together dive into some interesting trade-offs and find amazing new tools that carry…

Do you find yourself, or your team facing unsolvable problems? Problems that start to polarise and get decided by the people with the most rank? Or the majority vote decided and it resolves in a split in the team or in people feeling left out, or excluded? Perhaps you find yourself excluded from a team or company? Polarities cannot be solved, only managed. With polarity mapping we manage that polarity and go from either-or thinking to both-and thinking, and this way includes the entire team in…

Languages that raise the level of abstraction closer to the problem domain help improve quality and productivity. This can be best achieved when the language is directly based on the problem domain, not implementation concepts or existing languages. We describe how to create domain-specific languages in tight collaboration with domain expert users: as soon as a language concept is defined it can be immediately applied by users. We demonstrate this with examples from various fields, such as…

Per default, the standard library containers allocate their memory with new and release it with delete. These calls
• do not have deterministic execution times
• can lead to memory fragmentation
In many embedded applications this is not tolerable. Therefore, using standard library containers is not allowed.
With the allocators available since C++17 in the std::pmr namespace (polymorphic memory resources) these disadvantages…

C++20 is more or less out the door. It is probably the biggest change to the language since ever. In this session we will look into some changes that templates received with C++20. The biggest change is the introduction of Concepts.

We don’t stop there. We will also talk about improvements to CTAD and NTTP. Of course, we will also look into how templated lambdas work in C++20.

By the end of the talk you have learned about the newest C++20 template updates and how to apply them.

AI is maybe the most powerful tool our generation has available. Andrew NG called it "the new electricity". But what does it take to build AI enabled products? What are the key elements to achieve production grade AI? How does it impact your development process? How can quality be achieved? These are the questions this talk tries to answer. You will get an idea why the industry is talking about nothing less than a paradigm shift when it comes to developing AI based products.

Modern architectures (e.g. event-driven and reactive) will gain more traction as we build more complex systems, connect more distributed components and slice systems into smaller autonomous pieces. Unfortunately, many companies don’t update their business processes to reflect this. I’ll give an example and discuss the consequences, motivating you to advocate for a redesign of your business processes internally. Too much attention gravitates towards the technical side of reactive, without…

My hope for the future of software development; We learn that we are responsible for so many big and small impacts to society and that we have to take that seriously. We learn that even if software processes are described in great detail, we should not stop questioning whether we are still doing the right thing, the right way. We can bring our whole self to work. But most of all we learn that continuous integration is something you must have, continuous delivery is very nice to have, and…

Are the skills we apply as software developers of general value? Is our activity the collaborative exploration of creative spaces or the solitary application of mathematical techniques? This talk explores what programming can be, and what that means for teaching. Specifically, the prevalent approaches to teaching don't work, with disastrous effects for both inclusion and software quality. What does work is quite surprising. This talk gives a perspective on teaching from over 30 years of…

This talk will examine principles that assist with successfully evolving from a monolith to Microservices. Deciding what to decouple along with when and how to incrementally evolve a system are the main architectural challenges in this process. It is important to commit to "stop adding to the monolith" - all new code is added as microservices; the "Strangler Pattern". The new features are microservices, occasionally replacing part of the monolith. Also, when writing new microservices code, it is…

Raiffeisen Bank International (RBI) started in 2017 with “Group Digital Solutions” a journey in order not to oversleep the digitization of the banking industry.

Due to new approaches such as DevSecOps & Continuous Testing, the topic of software tests, whether manual or automated, had to be completely redesigned and implemented.

This talk gives insights into the test strategy & the fullstack test automation architecture that were used.

Target audience: testers, developers, architects, managers

For this keynote, Intel Software and TNG Technology Consulting go on a journey to some amazing innovations in Artificial Intelligence. Starting with the concept of Intel® oneAPI and introducing software development tools enabling a multi-architecture future, the keynote will travel in real-time to the AI Labs of TNG in Munich where Thomas Endres, Martin Förtsch and Jonas Mayer will take the audience on an exciting Live Innovation Hacking Tour showcasing the latest capabilities of AI at the edge.

Throw a line of code into many codebases and it’s sure to hit one or more testing frameworks. There’s no shortage of frameworks for testing, each with their particular spin and set of conventions and, but that glut is not always matched by a clear vision of how to structure and use tests — a framework is a vehicle, but you still need to know how to drive.

Compared to many languages, C++ has had slower widespread adoption of unit testing. This talk takes a deep dive into the practices and…

Looking back, especially now, makes us sad, but Linda will share scientific evidence that remembering the past provides measurable benefits. She'll outline the science and help us remember some of the "good old days" and then we'll all feel better.

Extended Abstract:
Many of us experience nostalgia as a bittersweet emotion. It combines the memory of good times with the ache of loss. You might think that people who are more nostalgic are…

Autonomous and automated systems are increasingly being used in IT such as finance, but also transport, medical surgery and industry automation. Yet, the distrust in their reliability is growing. This presentation introduces the validation of autonomous systems. We evaluate in practical situations such as automatic driving and autonomous robots different validation methods. The conclusion: Classic methods are relevant for coverage in defined situations but must be supplemented with cognitive…

After years of introducing “CI”/CD-Pipelines, after using Jenkins, CircleCI, Docker and K8s, your teams still don’t deliver software within minutes? And your customers still know about bugs before you do? Well, maybe you’re doing it wrong.

We’ll share our experiences on how to incrementally get organisations and systems to be able to leverage all the things associated with “continuous everything”. We argue for solutions tailored to individual situations, and more connected to software…

Over the history of software systems, the way we build such artifacts, the way we design them, the way we express them have evolved in seemingly disruptive ways. Even today, the pendulum swings between low ceremony agile methods to more rigid waterfall-ish ones; from big balls of mud to microservices and then back to big balls of microservices. In this talk, we'll examine the past, the present, and the future of software architecture: the role it plays in software systems, and the timeless…

At the core of agile development are self-organizing cross-functional teams. Yet, this is often understood as e.g. backend & front-end developers working together. If an organization is aiming for company-wide agility, to fully benefit from agility it has to enable teams as value centers that are truly cross-functional by bringing in different perspectives from business, markets, cultures, beliefs etc. This way cross-functional teams overcome not only the limitations of organizational silos but…

Sustainability is often defined as the interconnection of: social connection, economic wellbeing, and a healthy environment. The recent corona pandemic has yet again highlighted the potential as well as the necessity of a fundamental technology: the internet. However, to be sustainable, the internet also needs to assess, mitigate, and live up to its responsibilities for a healthy environment – an element of the equation that is too often neglected. What is the internet’s environmental impact and…
