Technical Coaching with the Samman Method
Technical Coaching with the Samman Method

For a technology company, building a strong engineering culture is essential for long-term success. Today's software industry is growing so fast that a large proportion of developers will inevitably have less than 5 years experience. At the same time, many software systems contain code that is ten, twenty or even thirty years old.

It's a constant challenge to communicate a healthy culture to newcomers and prevent technical debt from getting out of control. Technical coaching is all about tackling those issues: culture and skills.

Target Audience: Developers, Architects
Prerequisites: None
Level: Basic

Extended Abstract:
The Samman method is a concrete coaching method for spreading skills and culture within an engineering organization. There are two main parts to the method:
- Learning Hour
- Ensemble working

In the learning hour the coach uses exercises and active learning techniques to teach the theory and practice of skills like Test-Driven Development and Refactoring. In two-hour Ensemble sessions the whole team collaborates together with the coach in applying agile development techniques in their usual production codebase.

In combination with strong technical leadership, the Samman method can enable the spread of skills and culture to bring a healthy engineering organization to the next level.

Emily Bache is an independent consultant and Technical Coach. She works with developers, training and coaching effective agile practices like Refactoring and Test-Driven Development. Emily has written two books and teaches courses on platforms including Pluralsight and O’Reilly. A frequent conference speaker, Emily has been invited to keynote at prestigious developer events including EuroPython, Craft and ACCU. Recently Emily founded the Samman Technical Coaching Society, a not-for-profit organisation which aims to support and inspire technical coaches around the world.

Micro-Learning-Cycles (MLCs) – Lernen ohne Zeit
Micro-Learning-Cycles (MLCs) – Lernen ohne Zeit

"Ich hatte keine Zeit, den Zaun zu flicken" - Dieses Zitat kennt wohl jeder, und doch ertappen wir uns selbst, unseren Zaun nicht geflickt, sondern stattdessen die Hühner gesucht zu haben.
Doch wie ändere ich das?
Dieser Vortrag zeigt mit dem Konzept der MLCs ein Tool auf, dieser Falle zu begegnen und sich selbst und andere in den Modus des kontinuierlichen Lernens zu versetzen.
Am Ende haben die Zuhörenden einen ersten MLC durchlaufen und ein Tool erlernt, um sich und anderen den Freiraum zum Lernen zu erschaffen.

Zielpublikum: Coaches, Entscheider, Projektleiter:innen, Transformation Manager, Architekt:innen, Lebenslange Lernende
Voraussetzungen: Keine
Schwierigkeitsgrad: Anfänger

Extended Abstract:
Micro-Learning-Cycles sind kein theoretisches Konstrukt, sie sind tatsächlich aus der Notwendigkeit entstanden, trotz vollem Terminkalender Zeit zum Lernen zu finden.
Neben der Vermittlung und Anwendung von MLC zeigt die Referentin auch aus der Praxis, wo sie MLCs einsetzte, was funktionierte und wo auch Limitierungen sind.

Ihr Motto „You go first! – Nimm dein Leben in die Hand!", steht für ihr Tun: Rein in den nachhaltigen Erfolg durch Eigenverantwortung und Selbstführung.
Anne Hoffmann unterstützt Menschen und Organisationen dabei, erfolgreich ihre Ziele zu erreichen. Als Expertin für Selbstführung und mit ihrem Motto „You go first!“ erinnert sie daran, dass nachhaltiger Erfolg durch hohe Eigenverantwortung insbesondere dann entsteht, wenn diese Selbstführung vorgelebt wird.
Anne benutzt oft Spiele, um Erkenntnisse weiterzugeben.

Zero Trust for APIs: Patterns and Practices
Zero Trust for APIs: Patterns and Practices

Zero Trust Architecture has become the norm for how to modernize IT security in an age of growing network complexity and fewer ways to define hard network boundaries. Today, APIs are a standard way of how organizations expose both technical and business capabilities. But what does it mean for an API to be "Zero Trust Ready"?

In this presentation we look at some of the general patterns that APIs need to follow for Zero Trust readiness. We also look at some concrete practices for how to follow those patterns in your own APIs and API landscape.

Target Audience: Architects, Developers, API Designers, API Program/Platform Managers, Security Leads
Prerequisites: Basic knowledge of API terminology
Level: Advanced

Beyond Taming Technical Debt
Beyond Taming Technical Debt

Discipline, determination, a highly visible area, and a few sticky notes, are all you need to move beyond problems with technical debt.

Target Audience: Developers, Project Leader, Designers, Product Owners, Decision Makers
Prerequisites: Basic Knowledge of Software Development Process
Level: Basic

Extended Abstract:
## Making great software is challenging
It doesn't matter how qualified a team is, it will never be able to produce perfect, flawless, entirely bug-free software.
While teams are discovering how to build the right software in the right way, the environment the team operates in changes.
This results in a constant reorientation of the product, and the corresponding software solution, which will cause gaps between how things work, and how they should work.
Unfortunately, the market won't wait infinitely until teams have addressed these issues in the software, and organizations tend to run out of patience too.
That is why teams often have to move forward with designs and code that are ... let's call them sub-optimal.
These gaps, they are technical debt: a loan against the future, where things will be fixed, at some point ... Hopefully.
According to a global survey performed by Stripe, Inc. amongst software engineers in 2018, researchers found that **engineers estimate to spend 17,3 hours per week on addressing technical debt**.
That same research established that developers work about 41.1 hours per week. With that in mind, addressing technical debt constitutes well over a third of the time a typical engineer spends per week.
**If engineers are spending that much time, how could they better utilize their attention?**
Why do they seem unable to gain control over this metric and push it downwards?
While technical debt sounds nice and predictable: "you just have to pay interest", it really is like a loan with a mobster, and not with a bank.
It will show up unannounced at your doorstep at 3.30 in the morning, demanding that you pay up now!
How can you prevent being surprised by this goon?! And what can you do to leverage the benefits of borrowing against the future?
Because when the conditions are right, taking out a loan and paying it back Tomorrow might just help you ship a better product today.

## Imagine...
- A lightweight process to discover technical debt without a big investment up front
- A data-driven approach to identify the technical debt that needs attention right now
- A system that is easy to introduce, and simple to enforce
- Something that will guide engineers to articulate technical debt in terms of our roadmap
- Which will ultimately improve the flow of work in your organization

## The Wall of Technical Debt™️
A few years ago [Mathias Verraes coined the term "_The Wall of Technical Debt_"][1]. During this presentation Marijn Huizendveld will show you how to institute such a process for managed technical debt. Doing so will provide you with a safety net that allows you to make "naive" design choices every now and again to ship your ideas as fast as possible, without sacrificing sustainable delivery in the long run.
[1]: verraes.net/2020/01/wall-of-technical-debt/

Marijn Huizendveld – In a small backstreet of Tokyo lives a man named Aki, a 78 years old former chef. Aki spent most of his life trying to perfectly cook the rice he buys from his friend Mato. He's been at it for 57 years now, and still searches for ways to improve his cooking methods. There is probably not too much anybody else could tell Aki about cooking this specific type of rice. When it comes to his process, Aki's understanding is unrivaled.
After years of trial and error, Marijn Huizendveld could be called the Aki of Domain-Driven Design, due to his extensive background in both programming and strategy. He uses this experience to show teams and organizations how to recognize and act on problems and opportunities in an autonomous, self-learning fashion.

Maintenance and Evolution of Large Scale Software Systems – Business, Dev & Ops Challenges
Maintenance and Evolution of Large Scale Software Systems – Business, Dev & Ops Challenges

Even in the time of agile software development and devOps, maintenance and evolution of large-scale software systems remain challenging. This is not only caused by technical debt, but is heavily caused by lost knowledge, high complexity of micro-service architectures, difficult requirements management, not available documentation, and the complexity of communication among and coordination of the many stakeholders. In our session we will talk about the challenges we identified in our study and present new approaches to address these challenges.

Target Audience: Architects, Developers, Project Leader, Manager, Decision Makers
Prerequisites: Project Management Experience, Software Maintenance
Level: Expert

Use Testing to Develop Better Software Faster
Use Testing to Develop Better Software Faster

As developers, our job is to deliver working software. With the shift to CI/CD and the move to the cloud, the need to have the right feedback at the right time only increases. There are many ways that testing can help us with that. Not only can testing help us verify our solution and prevent us from breaking things, it can also help us design our software, find flaws in our architecture and come up with better solutions. In this talk I will highlight some of the many ways that testing can help you to develop better software faster.

Target Audience: Developers
Prerequisites: Basic knowledge in Java
Level: Advanced

Extended Abstract:
Testing doesn't always get the attention it deserves in software development. Many developers claim to be bad at it, or are just not that interested. (These may or may not be related.)

Micro-Service Delivery without the Pitfalls
Micro-Service Delivery without the Pitfalls

In this session I’ll examine some of the things that can go wrong when organisations jump headfirst into micro-service architectures without understanding the potential pitfalls.

I'll explain contract testing from the ground up. You'll learn how it can decouple micro-service dependencies during development, allowing your teams to work effectively. And I'll describe sophisticated, free, open-source tooling that helps integrate contract testing into your software lifecycle, giving you the confidence to release micro-services independently.

Target Audience: Architects, Developers, Decision Makers, Release Managers, DevOps
Prerequisites: English, basic software design/architecture, software lifecycle

CANCELLED: Diversity, Equity, and Inclusion: Theoretical and Practical Reflections on Finding the Right Balance in your Organization
CANCELLED: Diversity, Equity, and Inclusion: Theoretical and Practical Reflections on Finding the Right Balance in your Organization

Unfortunately, this presentation has to be cancelled at short notice for personal reasons.

This talk covers the fundamentals of diversity, equity, and inclusion (DEI), including key definitions and statistics. Moreover, the link between DEI, sustainability, and innovation will be made, including reflections on the importance but also complexity of finding a balance.

As part of this talk, I will link theory and research to my work as the Global Head of Diversity, Equity, and Inclusion in a fintech company, including giving practical examples of how we are embedding DEI into our organization.

Target Audience: People Leaders, Managers, Decision Makers, C-suite
Prerequisites: Open-mindedness, interest in DEI
Level: Basic

Extended Abstract:
What does diversity, equity, and inclusion have to do with sustainability and this year’s conference focus on “finding the right balance?” Everything.

In this talk, I will cover the basics of D, E, and I including definitions and statistics, including introducing various “diversity dimensions” and the concept of “intersectionality.” Then, I will link the DEI agenda to the people sustainability agenda, including showing how the world is already diverse and if your organization is not: how you are likely missing out on learning, development, innovation, user experience knowledge, and even market share.

In doing so, I will link theory and statistics to my work as Global Head of Diversity, Equity, and Inclusion in a fintech company, including giving practical examples on how we are embedding DEI into processes and policies. Finally, I will give reflections on how DEI is a journey that also must be balanced and prioritized, just as any other business priority, before opening up to audience questions.

Elizabeth Benedict Christensen, Ph.D. has extensive theoretical and practical experience in diversity, equity, and inclusion in the academic and business worlds. Elizabeth has taught at university-level about Diversity, Cultural Analysis, Communication, Research Methods and beyond. She completed a Ph.D. on sense of belonging before returning to the business world in 2017 to bridge theory with practice, including sharing her passion for DEI globally.

You're in Charge – Now What?
You're in Charge – Now What?

What should you do if you are promoted or hired to be the first Head of Architecture in a big, international organisation? What should you do to shape the role to deliver value to the organisation and its customers? How do you work with many development teams to shape the current legacy spaghetti mess into a coherent system, without becoming a bottleneck?

In this talk I'll respond to all questions and more, by sharing my experience in becoming the first Head of Architecture in a big international organisation.

Target Audience: Architects, Developers, Senior Managers
Prerequisites: Knowledge of software architecture
Level: Expert

Extended Abstract:
In this talk I'll share my experience in becoming the first Head of Architecture in a big international organisation, and on how I shaped the role to deliver value both to the organisation and its customers. Among other things, I'll share what I did to:

- Work productively with the development teams and be relevant.
- Navigate the political landscape to influence decisions.
- Create an architectural decision process tailored to the needs of the organisation.
- Provide guidelines and constraints to decentralise decision making while avoiding chaos.

The attendees will get a better understanding of what the role encompasses, and future heads of architecture may get a better view of what expects them in this role.
