Code Wars: Bringing Balance to the Design Force
Code Wars: Bringing Balance to the Design Force

How much design is enough design? How much is overdesign? When does — or should — design happen? How big is 'design'?
Anyone who has ever looked at the methodology landscape or has juggled different roles in software development — programmer, architect, coach, therapist, code paramedic, politician — knows that there are many answers to these questions, and they often contradict one another.

In this talk, we will consider different scales and time frames of design in software, bringing some balance to competing perspectives and recommendations

Target Audience: Developers, Architects, Tech Leads, Project Leads
Prerequisites: Interest in software architecture and design
Level: Advanced

A Commune in the Ivory Tower? – A New Approach to Architecture
A Commune in the Ivory Tower? – A New Approach to Architecture

Traditional (i.e. hands-off, blessed-few) approaches to architecture rarely (if ever) work. But in the world of microservices, autonomous teams, and continuous delivery, architecture is more important than ever. Is there an alternative?

Target Audience: Architecture Practitioners (Architects, Lead Developers, etc.)
Prerequisites: Experience delivering software architecture
Level: Advanced

Extended Abstract:
I’m an architect, and I think a lot about architecture. Mostly I think about how irrelevant architecture is if it doesn’t get shipped to production. I worry a lot too. I worry about how to help all the teams I’m supposed to be helping, without slowing them down, getting in their way, or making their lives harder rather than easier.

This paper introduces a mindset and an associated set of practices which do away with the traditional idea of “Architects” while bringing the practice of “Architecture” to the fore. I’ll explain how I and colleagues have used this approach at multiple clients to help everyone become an architect, without things reducing to chaos (though there is a healthy dose of anarchy).

A highly enthusiastic, self-starting and responsible Tech Principal; Andrew Harmel-Law specialises in Java / JVM technologies, agile delivery, build tools and automation, and domain-driven design.
Experienced across the software development lifecycle and in many sectors including government, banking, and eCommerce, what motivates him is the production of large-scale software solutions, fulfilling complex client requirements. He understands that people, tooling, architecture and process all have key roles to play in achieving this.
Andrew has a passion for open-source software and its communities. He has been interested in and involved with OSS to a greater or lesser extent since his career began, as a user, contributor, expert group member, or paid advocate.
Finally, Andrew enjoys sharing his experience as much as possible. This sharing is not only seen in his formal consulting engagements, but also informally through mentoring, blog posts, conferences (speaking and organising), and open sourcing his code.

Cloud Chaos and Microservices Mayhem
Cloud Chaos and Microservices Mayhem

The cloud has fundamentally changed how we design applications and introduced whole new categories of software-development disasters. With a focus on Java, this talk will introduce some of the new tools, patterns, and best practices for modern distributed application development. It also gives a tour of some of the most painful anti-patterns Holly has seen as a cloud consultant.

Target Audience: Architects, Developers, Strategic Decision Makers
Prerequisites: Basic experience of cloud computing, Knowledge of Java
Level: Advanced

Extended Abstract:
The cloud is just someone else's data center, but it has fundamentally changed how we design software and what we expect from our platforms. Our applications have gotten bigger, more distributed, and more complicated, and there are whole new categories of mistakes we can make. Some things that were a good idea ten years ago turn out to be a terrible idea in the cloud; and what used to be ‘good enough’ for testing really isn’t anymore. Managing microservices architecture demands a lot of us, to ensure observability, operational resiliency, and organisational agility. With a focus on Java, this talk will introduce some of the new tools, patterns, and best practices for modern distributed application development. It also gives a tour of some of the most painful anti-patterns Holly has seen as a cloud consultant.

Can High Performing Software Solve the Climate Crisis?
Can High Performing Software Solve the Climate Crisis?

Green software engineering is an emerging discipline and being a part of the climate change solution is a relatively new part of many software companies' strategy. For some of us, building resource efficient solutions is something we have already done for a long time, but we called it performance work. Where do the two meet and when are they different? This talk introduces the field of green software engineering and explains where it intersects with performance optimizations, giving you the tools to take an active part in the climate solution.

Target Audience: Architects, Developers
Prerequisites: Basic understanding of software and performance metrics like latency and resource utilization
Level: Advanced

Extended Abstract:
Software has a huge carbon footprint and impact our global commitment to keep global warming to no more than 1.5°C – as called for in the Paris Agreement. To reach this goal, emissions need to be reduced by 45 % by 2030 and reach net zero by 2050. The rising interest in getting a better handle on the carbon emissions of software has garnered interest from the research and practitioner communities across industry, government, academia, and civil society.

The objective of this session is to break beyond surface-level discussions and dive deep into understanding the challenges and opportunities related to assessing and mitigating the carbon impacts of software systems, through the lens of high performing software.

The Lost Art of Software Architects
The Lost Art of Software Architects

In 2022, is having a dedicated software architect still useful, or are there better ways to fulfil this role? The answer, as usual, is "it depends”.

Target Audience: Software Developers and Architects
Prerequisites: None
Level: Advanced

Extended Abstract:
Traditional approaches to software architecture usually trigger thoughts of ivory tower dictators who are a long way removed from the process of building software, probably because they no longer write code anymore. This unfortunate stereotype of “architecture astronauts” delivering large design documents to the development team before running away to cause havoc elsewhere has unfortunately resulted in a backlash against having a dedicated architect on a software development team, particularly in environments where teams are striving to be autonomous and self-organising.
But, in 2022, is having a dedicated software architect still useful, or are there better ways to fulfil this role? The answer, as usual, is “it depends”.

Simon Brown is a renowned consultant specializing in software architecture, and the author of some of the most popular software architecture books, including „Software Architecture for Developers” (a developer-friendly guide to software architecture, technical leadership and the balance with agility). He is also the creator of the C4 model for visualizing software architecture, and the founder of Structurizr.

XP – 25 Years Later: Balancing New Tech and Proven Practices
XP – 25 Years Later: Balancing New Tech and Proven Practices

When Extreme Programming (XP) was first described 25 years ago the IT industry was in a different place. Since then, we've seen widespread adoption of agile approaches, the rise of the open source and public cloud ecosystems, and much more. And while these trends have improved our ability to deliver complex software systems, the mastery of the actual craft — working effectively in a team, delivering quality software at a sustainable pace — is as important as ever.

This talk will place XP into today's world of modern software development.

Target Audience: Developers, Architects, Software Engineers

Take it Back
Take it Back

Das agile Manifest wurde vor über 20 Jahren von Entwicklern für Entwickler geschrieben. Mittlerweile fühlt es sich aber immer mehr an, als ob die agile Bubble eine eigene Welt ist, die von Scrum Mastern und Agile Coaches übernommen wurde. Developer nehmen eher passiv an den vorgeschriebenen Meetings teil, statt den Prozess aktiv zu gestalten.
Was läuft da schief? Und wie können wir das ändern?
In dieser Session geht es um Motivation, sinnvolle Konflikte und Empowerment.

Zielpublikum: Architekt:innen, Entwickler:innen, Projektleiter:innen
Voraussetzungen: Projekterfahrung

Creating Sustainable Change When Skeptics are Lurking
Creating Sustainable Change When Skeptics are Lurking

When you want to make a change, the skeptics are lying in wait throughout the process. You must continually recognize them if you want the change to be sustainable. Who are they and why are they resisting?

We want to be understanding but oh, they can be annoying. We are told to increase communication, but before shouting more information, we must understand why they are irritating us.

This presentation will provide some practical tips for identifying and dealing with resistance in your organization and perhaps in your personal life too.

Target Audience: Everyone who sees a need for change but also sees resistance
Prerequisites: None
Level: Advanced

Extended Abstract:
When you want to make a change, whether it be agile, AI, cloud, microservices, or anything (!), the resistors are lurking everywhere throughout the process. You must continually recognize them if you want to create a sustainable change. Who are they and why are they resisting? We want to be understanding but oh, they can be annoying. We are told to increase the communication, but first we must understand why they are irritating us before we are tempted to shout more information at them.

This fits into the conference theme of Finding the Right Balance because leaders must continually handle skepticism surrounding the change while, at the same time, moving the process forward at a rate that attempts to work for everyone. As the Signature Track describes, this presentation will, “illuminate the area of tension in which decisions can be made, but also to show practical tips and empirical values so that teams can make the appropriate decisions.”

In a fun and enlightening way, it will point out why resistors annoy us and offer some practical tips that attendees can use on Monday morning for identifying and dealing with this resistance in their organizations and perhaps in their personal lives too.

Mary Lynn Manns, PhD, is the co-author of two books with Linda Rising, "Fearless Change: Patterns for Introducing New Ideas" and "More Fearless Change: Strategies for Making Your Ideas Happen". She has led numerous presentations and workshops on the topic of change throughout the world at conferences and in organizations that include Microsoft, amazon.com, Apple, Procter & Gamble, and Avon.
