Micro-Frontends eigenen sich nicht in allen Szenarien! Diese Session stellt einen alternativen Ansatz vor: Frontend-Modulithen. Wir besprechen das Abbilden fachlicher Domänen, die Kategorisierung von Bibliotheken sowie Zugriffseinschränkungen zum Erzwingen entkoppelter Teilsysteme. Außerdem nutzen wir inkrementelle Builds und einen Build Cache zur drastischen Beschleunigung des CI-Prozesses. Am Ende wissen Sie, ob Frontend-Modulithen für Sie der richtige Ansatz sind und wie Sie Ihre Anwendungen…

Imagine you have an enterprise frontend monolith. Due to explosive growth, around 30 teams work on it, with about 100 different use cases. How do you keep this system scalable and consistent?
That's the question we faced inside Partner Home at Wayfair. I'm going to share our experience implementing a micro frontend architecture based on React to distribute shared concerns as long-lived applications. We used module federation, a new feature in Webpack 5.
I'll talk about the general architecture,…

Orchestrating the work of hundreds or thousands of people working at different locations around the world presents a set of challenges specific to that kind of context. It is not simply a matter of “scaling up", we need to understand underlying principles and patterns and make them work. With this session we invite you into a conversation about how to improve the way leaders and teams collaborate in our organizations. You will experience a workshop that you can reproduce for your organisation to…

How will organizations keep agility alive after their initial agile transformation? The question of what happens if agile becomes daily business is even more intriguing in this post-pandemic COVID era. Will AGILE survive these unparalleled insecure times? Participants in this workshop will explore what is needed to sustainably ‘safeguard’ an enterprise agile delivery culture after the initial ‘agile transformation’. The workshop hosts will share their observations of working in a big financial…

C++20 is now a year old. Time to take a closer look at the benefits you get when using C++ for standards 11 to 20. You learn about Coroutines by building a coroutine-based parser. The new ranges and the spaceship operator help you write less code. You will learn how Concepts help you to express constraints better and improve error messages. Doing things at compile-time saves run-time. Let‘s see how C++20 improves your code with the new features consteval and constinit. After this talk, you…

While Rust is typically pitched as systems programming language, it is equally adept at application development thanks to its high level features and great tooling. In addition to increased performance, native code has the advantage that it can easily be reused across different system components, an advantage even more pronounced in polyglot environments. In this talk, we would like to present our experience of using Rust to write core components in such a polyglot system.

Women in technology leave the industry at a higher rate than any other profession. In her invited talk, Nicola Marsden draws on deep research into what women love about work and what they don’t. Together with Karen Holtzblatt, the visionary behind Contextual Design, she has developed a research-driven framework and best-practice interventions to achieve better retention and work life culture for women in technology. She presents the framework and looks at Scrum as an example in terms of…

Today Computer vision has taken a significant spot in our phones, our roads, our markets that we don’t always even recognize if and where it is deployed. Nonetheless, our industries today have so much potential to automate (using CV) their recurrent tasks to reduce costs, while simultaneously increasing quality of the product and efficiency of the process itself. We will learn about some interesting industrial examples which benefit first-hand from simple automation and perhaps get inspired by…

C++ class design has been error prone since the beginning, until Scott Meyers told us about the Rule-of-Three. But even that is not enforced by the language. In addition, C++11 changed the set of compiler-provided special member functions and the intrinsic rules have become more complicated. However, instead of starting from the rules for special member functions, we will look at what role a class type plays and how that maps on what special member functions to define and how, if any. Examples…

Many of us have a rough idea of what side-effects are and a vague sense that they're bad. It's a shame we're not more precise about it, because when you really understand side-effects you have an excellent new lens through which you can judge individual blocks of code, larger architectural patterns, and even whole system designs. So let's start by clarifying our understanding of what side-effects are and how to spot them. We'll see how easily they arise, leaving code that's harder to understand,…

Software is often resistant to modernization efforts, no matter if it's about phasing out obsolete technologies, migration to the cloud, or establishing modern architecture. The culprit is usually a dependency or obsolete assumption that's too closely coupled to the codebase. But what's the underlying root cause of all that coupling? Often, it's shared, mutable, synchronous state. We will look at a real-world project, and we'll dig ourselves out of the hole it's dug itself into using…

In today’s software-driven world, the integrity of software assets isn’t just a regulatory and compliance requirement, it’s critical for maintaining trust and avoiding irreparable damage to your brand and reputation. We found that Compliance, Software Chain of custody and in-App Security as well as API Security are seen as an overburdened bureaucracy. But they have to be part of your software value stream. So the question is, how they can be so lean, automated and optimized that they can…

For many embedded C++ applications, compliance with the AUTOSAR or Misra rules is required. Among them is AUTOSAR Rule A18-5-5 which does not allow memory allocations with new. Since new and delete violate A18-5-5, the default STL containers must not be used in applications requiring AUTOSAR compliance. This holds for many embedded applications. With the allocators available since C++17 in the namespace std::pmr (polymorphic memory resources) these requirements can often be satisfied.

The purpose of Serverless is to focus on writing the code that delivers business value and offload undifferentiated heavy lifting to the Cloud providers or SaaS vendors. Today’s code quickly becomes tomorrow’s technical debt. The less you own, the better it is from the maintainability point of view. In this talk I will go through examples of the various Serverless architectures on AWS where you glue together different Serverless managed services, significantly reducing the amount of the code…

In a world of rapid changes and increasing uncertainties, organizations have to continuously adapt and evolve to remain competitive and excel in the market. In such a dynamic business landscape organizations need to design for adaptability. Designing for adaptability requires understanding the landscape organizations are operating in, identifying patterns of change, applying principles for organizational fitness, and making mindful strategic decisions to adapt change.

Target Audience: Software…

New MISRA C++ 202x are coming. This release will address modern C++ and thus is relevant not only for safety critical code in the automotive sector, but also for day-to-day C++ development. Expect the new MISRA rules to be less "miserable" for your day-to-day coding and use static analysis tooling to enforce them. Understand what kind of C++ will be considered unsafe, get examples of guidelines and learn which rules better to suppress in static analysis tools in non-safety-critical software.

What have we learnt from the transformations in large companies? And how can that help you improving your chances for success?

The DACH30 group is a workgroup of experienced transformation drivers and coaches from over 30 large companies across different industries. One sub-workgroup has been working on these two questions and we recently published our findings.

In this workshop we will share our transformation experiences and work out with you on patterns, that have proven to be helpful in…

(Agile) Games are sounding throughout the land. Everyone plays games and anyone guides games. However, what makes playing games "interesting" from the business owner's perspective? 

We look into the criteria of effectiveness and efficiency of games and thus the capabilities of creating business impact for the company.

As such, it turns out a game - is just a game and remains a play if one does not align with underlying business needs. Sounds familiar? But you wonder how to do so?

In this talk,…

So many challenges, so little time. As testers or quality engineers, we need to sharpen the saw, but how? Gamification can be a way to look at how you're doing and find out where to improve. It's a great way to have everyone engaged and get the best out of people.

In this presentation, Ben Linders will show how playing games (onsite or online) with the Agile Testing Coaching Cards and Agile Quality Coaching Cards help to explore your current quality and testing practice and decide as a team on…

Wollen wir unseren Enkeln eine lebenswerte Welt hinterlassen, müssen wir das grundlegende Paradigma unseres Wirtschaftssystems umbauen: Weg vom ausbeuterischen Wirtschaften, hin zu einem regenerativen, demokratischeren und inklusiven Wirtschaften.

Der Vortrag ist ein Plädoyer dafür, nicht auf Politiker, Konzernchefs oder ein Wunder zu warten, sondern selbstbewusst aktiv zu werden. Wir stellen erste Ansätze vor, wie Agilität konkret genutzt werden kann, um den Umbau der Wirtschaft in Angriff zu…

This is a letter from the future: we are working in an organization in a galaxy not so far away … we have a #diverse #social #digital #remote #culture - and we will tell you how we got there. We leave it open to the audience to guess how far this future is away. Or how near they want it to be. Disclaimer: may contain fragments of reality.

The adoption of static analysis of C++ and Java requires that the findings and errors can be prioritised in an efficient way. Our work shows that Machine learning (ML) can support this presentation of static analysis results to end-users. The ML engine learns from the codebase itself, and also observes the violations that the user fixes and which he ignores. The ML uses this to suggest the next best violations to fix, relying on probability of violations to be harmful or most likely to be a…

Maintaining a database containing millions of products can be very challenging, especially when the information you require of these products is subject to changes over time.

We show how we used state of the art Deep Learning methods (such as Transformers, BERT) in connection with smart text matching in order to extract relevant information from free-form text.

We also explain how we leveraged the existing database to create an automatically labelled training dataset.

Our model enables us to…

To continuously deliver IT systems at speed with a focus on business value, high-performance IT delivery teams integrate quality engineering in their way of working.

Quality engineering is the new concept in achieving the right quality of IT systems. Testing only after an IT product was developed is an outdated approach. Built-in quality from the start is needed to guarantee business value in today’s IT delivery models. Quality engineering is about changes in skills, organization, automation…

In large software projects the assessment of the impact of a code change can be a cumbersome task. If the software has grown and shows an evolutionary design there are always unwanted side effects.

Change control boards are established. But on what data do they judge what can happen with the changes? Very often there is the HIPPO syndrome which means it is the highest paid person's opinion.

In this talk we will show you ways to come to a deterministic prediction of the impact, what data you need…

On-Call is an increasing reality for developers, especially when a site has strict uptime requirements. And sadly, the experience often sucks. It's easy to mandate 24x7 support, it's much harder to set it up in a way that doesn't make the life of the people in the rotation miserable.
I want to talk about improving alerting. I'm focusing on creating high-quality alerts that trigger when they should and don't trigger when nothing is happening. Continuous tuning, automation, and using the right…

The idea of looking at your organization as a single coherent system is tempting, but is it realistic? If it isn't, what does that mean for software developers, and how can we make discoverable what we are developing? This talk looks at organizations as ecosystems rather than as systems, and asks what that difference means for software development. It all boils down to focusing on software as components implementing business capabilities, and how to best capture these capabilities and make them…

Stories from a High Performing Team is a talk about the teamwork in a software development team at ThoughtWorks, a global Tech Consultancy. The team including the speakers - Jennifer (Developer), Xiaofan (Experience Designer) and Ursula (Business Analyst) - have been working for 14 month together which is a rare case in the consultancy business. The team is known for being high performing and today they want to share stories and practices for agile software development teams on how to reach this…

If any person or groups of people feel unwelcome because of the language being used in a community, its products, or documentation, then the words should change. We can choose words that are precise, not dependent on metaphors, and convey messages without negative connotations.
We will discuss the process of auditing our own work and identifying divisive language. We will also talk about methods to standardize replacements and collaborate with writers and product developers to carry out these…

Besides IoT and Machine2Machine communication Digital Twins are a cornerstone of the fourth industrial revolution. In general, a Digital Twin is the virtual replica of a physical object or system. But what does this mean in detail – what are the ingredients of a Digital Twin? How can Digital Twins be built and utilized and what value do they bring? This talk gives an overview of different types of Digital Twins, different applications from public to industrial utilization and architectural…

Due to the capabilities of Kubernetes, the usage of patterns rises to solve complex questions, but causing often confusion and unnecessary implementations. This talk intends to show what are the right scenarios for and for which cases another pattern is more suitable.
In this talk, Max will introduce you to various patterns, often misused by running applications and services within Kubernetes. The focus will be on structural patterns like Sidecars and Ambassadors as well as more advanced patterns…

Some codebases are nicer to work with than others. This is true for applications, services, libraries, frameworks, even programming languages themselves. Is this a purely personal choice or are there universal characteristics of software that can make code a joy to work with? Daniel has been thinking about this for a long time, especially since he poked a stick at the SOLID principles for fun a few years ago and people came after him with pitchforks.

Agile is becoming a standard delivery method adopted by organizations across the globe, according to VersionOne’s 11th Annual State of Agile Report. While 94 percent of survey respondents said their organizations practiced Agile, 80 percent said their organization was at or below a “still maturing” level. There are multiple reasons on why the Agile maturity of the teams are low, but the key one is teams look at Agile as a process change rather than a cultural change.
At Accenture we have been…

The clean code principles are well-known in modern, agile software development. But what has become the default for our business code, unfortunately by no means applies to our infrastructure code. Instead, we find badly crafted, complicated and highly tangled code that is manually tested using a trial and error approach. However, for modern cloud based systems the infrastructure code plays a crucial role. So it's about time we begin to treat it as a 1st class citizen! This hands-on session shows…

Data technical debt refers to quality challenges associated with legacy data sources, including both mission-critical sources of record as well as “big data” sources of insight. Data technical debt impedes the ability of your organization to leverage information effectively for better decision making, increases operational costs, and impedes your ability to react to changes in your environment. The annual cost of bad data is in the trillions of dollars, this problem is real and it won't go away…

Who drove your digital transformation? Your CEO? Or COVID-19? Across workplaces, markets and everyday habits, the pandemic transformed our world beyond our control. The way that we work, what we work on, even why we work were all transformed in ways that few organisational transformation programs ever achieved. Software played a key role in this transformation and, for better or for worse, it runs the world. We will explore the changes to the way we live that have moved from possibilities to…

Each project has its own unique technology stack, different business logic and a unique team. The definition of quality in our projects can vary greatly. However, there are good practices that will work everywhere. There are steps that can be taken in every project and team to produce the software of better quality. I will tell you how to improve communication and processes, and what tools we can use not to be ashamed of the fruits of our work. Everything from a programmer's perspective.

“TDD is when you write tests before implementing the business logic” - a simple sentence that is also often misunderstood.
Moving from one project to another, I have observed how many times people were terrified of TDD. I have been there too.
This session will focus on trying to understand HOW and more importantly WHY you should consider TDD. I've transformed failures from my experience into a series of lessons learned, things that in hindsight should have been obvious.

Target Audience: Architects,…

In this talk, we will give an overview about all the different aspects that affect climate change from the software engineering perspective and discuss a number of concrete actions that every software engineer can take (and should keep in mind day-in day-out) to help fight climate change. During the talk, we will not only provide an overview of the landscape, but also cover topics in more depth and discuss the challenges that come with them.

With AI entering more and more aspects of our lives, scepticism and worries towards this technology are increasing too. Empathy towards basic human needs and a great User Experience can help AI being more widely accepted and used.
But how to get there?
After covering basic UX principles, the talk will deep dive into the fields of trust, transparency and explainable AI.
The goal is to outline a path to a fruitful collaboration and…

The world in which a software system lives is filled with meaning. The structure, concepts and names that inform the code, its changes and the mental models held by developers are expressions of meaning. The very act of development is an exercise in meaning — it's discovery, its formulation, its communication.
But just because we are immersed in concepts of meaning from an early age, and just because the daily work of software development is about wrangling meaning, that doesn't mean we're…

I will introduce two AWS services: CodeGuru and DevOps Guru.
CodeGuru Reviewer uses ML and automated reasoning to automatically identify critical issues, security vulnerabilities, and hard-to-find bugs during application development.
DevOps Guru analyzes data like application metrics, logs, events, and traces to establish baseline operational behavior and then uses ML to detect anomalies. It does this by having the ability to correlate and group metrics together to understand the relationships…

Everyone wants to innovate, the question is how do you change your environment to support innovation?
Gabrielle will introduce the innovation imperative; why innovation is a necessity, a look at the disruptors threatening the fundamental ways we do business, and how to create a sustainable innovation strategy. 
We then go to the mean streets of Chelsea, London and meet Riccardo Mariti of Riccardo's restaurant. Riccardo will show you need to disrupt your business before you get disrupted and the…

This talk describes how to build and run a successful product development organization that delivers business value, not just features. I will cover what makes effective product development teams, how to structure, loosely couple, align and choreograph them, especially in larger organisations with up to 100 teams. Methods I will talk about include OKRs and Kanban Flight Levels. In this context I will also show when and how decentralised product teams can benefit from centralised platforms.

Within DDD we have the perspective of strategic design where we can split a large-system into multiple sub-domains, each having its purpose and responsibilities, where teams can work in autonomous, clean bounded contexts. One of the most effective ways to define these boundaries is by collaborative modelling with all the stakeholders involved in these domains. Join us were we share war stories about our experience doing collaborative modelling in several companies with 30+ people.

For most people, AI means robots taking human jobs or China’s surveillance of its citizens. Despite the hype around it and its image of progress, the real workings of artificial intelligence are not widely understood. Companies are already implementing a web of algorithms to optimize manual business processes. Most of the time, the larger IT organization is not included on the journey. This talk is an overview of how IT leaders can center the development of human teams in a world that is…

When breaking up our software into modules we all too often forget the important social aspects; how the design affects the teams. We need modules that not only make us efficient but also harmonious.
We know that good fences make good neighbours, but only when the boundaries are placed correctly. We are going to take a closer look at why modularity is needed, what it actually can do for us, and how we can increase our chances of getting it right by taking a systems thinking approach.

Machine Learning appears to have made impressive progress on many tasks from image classification to autonomous vehicle control and more. ML has become so popular that its application, though often poorly understood and partially motivated by hype, is exploding. This is not necessarily a good thing. Systematic risk is invoked by adopting ML in a haphazard fashion. Understanding and categorizing security engineering risks introduced by ML at design level is critical. This talk focuses on results…

The primary cause of technical debt in your organization is very likely your project managers – not your programmers nor your architects. In this keynote Scott Ambler explores the root causes of technical debt within organizations, many of which trace back to the project management (PM) mindset and the strategies that result from it. Scott works through how to make leadership aware of technical debt and its implications, how to evolve your management practices, and strategies to embed technical…
