Continuous experimentation, when software engineers are invested in product and business
Is it virtuous for a company to let its software engineer invest in the product and the business? In contrast to a hands-on approach, we have chosen to take a central role, self-managing, to cover the phases from gathering requirements to following u ...

Model Tension Heuristics: Preventing Accidental Design Debt
”All models are wrong, but some are useful.” This insight from George Box has become a cornerstone of software modeling. While exploration and experimentation are essential for shaping models, it is often challenging to know when a model is wrong or, ...

A Defense of Technical Excellence
The speed / quality trade-off fallacy gets many teams stuck in downward spiral feedback loops - sacrificing quality for speed, both are lost. Teams find their backlogs filled with bugs, their stakeholders frustrated by missed deadlines and the te ...

Taming technical debt: from burden to strategic advantage
Let’s flip the table. Instead of considering technical debt like this shapeless burden that just happens to be there, let’s analyse debt’s characteristics and when and how it appears. Then let’s dig into how we can get an accurate view of technical d ...

Preparation - The underrated potential for CoMo workshops
When it comes to Collaborative Modelling (CoMo), simplicity and adaptability are often perceived as defining strengths, but this notion of "just adapting on the fly" can be misleading. Many CoMo methods are deceptively simple, creating false confiden ...

Security and Architecture: To Betray One Is To Destroy Both
Flawed architecture introduces vulnerabilities that even the best security cannot mitigate. Likewise, a well-architected system without robust security remains a ticking time bomb in the face of modern threats. In this talk, I will explore how these ...
