QWAN - Quality Without a Name

Our Services

Consultancy & mentoring

We take a holistic, systemic approach to grow your development organization. An effective software development organization needs to attend to technical skills, agile processes, team organization, and personal growth.

Training

We deliver courses on (agile) software development. Small groups, intensive courses, hands on, VERY interactive ... & fun!

Software development

Have we mentioned that we're software developers? We are. And we're passionate about the quality of our work. We believe that for sustainable development, we need state-of-the-art practices like test driven development, continuous integration and relentless refactoring.

Werken met Rob en Marc is een bijzonder geruststellende en inspirerende ervaring. Ze hebben in onze transitie naar een totaal nieuw systeem, nieuwe architectuur en een hernieuwde definitie van craftsmanship een cruciale rol gespeeld. Met hun unieke stijl vertalen ze hun verbluffende kennis en ervaring naar kleine stapjes en hebben ons daarin meegenomen op een manier dat we werkelijk het idee hebben dat we het zelf bedacht hebben. Wat dit betekent voor draagvlak en slagkracht moge duidelijk zijn. Zonder Rob en Marc was ons dit niet gelukt.

-Geert Bossuyt, delivery manager at ZorgDomein

Duurzaam Agile software ontwikkelen vergt niet alleen een Agile mindset, maar ook een Agile skillset. QWAN heeft ons geholpen om die te ontwikkelen. Niet door advies vanaf de zijlijn, maar door actieve participatie op het spelveld. Samen de handen vuil maken en lering trekken uit de praktijk. De ene keer door het stellen van coachingsvragen, de andere keer door het voorbeeld te geven of door het geven van instructie. Steeds wat nodig is om verder te groeien als ontwikkelaar en als team.

-Hans Kalle, development manager at RIGD-Loxia

At your TDD training course, I actually learned something! (comparing with other unit testing courses)

Very educational (as I expected); I can definitely apply this in my project

“This was the first training where I had:
- no problem to stay awake
- no problem with the afternoon "dip"
- no problem to stick to the subject
- no problem completing the exercises.

Managing coupling through Hexagonal Architecture

03 February 2026

We wrote in our previous post on coupling: without coupling there is no working software, but how do we keep coupling manageable? In this post, we will look at Hexagonal Architecture from a coupling perspective. Hexagonal Architecture is about decoupling domain logic from frameworks and the outside world - but what does decoupling actually mean?

How does the human stay in the loop, while developing on their phone?

02 February 2026

Working with LLMs to create prototype webapps from my phone can be very satisfying. There are limitations, though. Having only a tiny terminal window with a coding agent can feel like painting my living room through the letterbox. Code scrolls by quickly, and I look at a few lines at a time, which makes me lose sight of the whole. So after some prototyping, I have to find time and space to sit with a microprint, to see the forest and the trees.

New partner - Sensus

28 January 2026

“You deserve to understand your software!” This is what came out as tag line for Sensus’ Architecture Review service. After Stephan Eggermont’s The state of LLM Agentic Flows went viral on LinkedIn, it was high time to describe the kind of thing they do for clients in more detail.

On coupling and cohesion

23 January 2026

Coupling and cohesion are old ideas, but they are still relevant today - vintage concepts that have aged well. Recent posts by Martin Dilger and Eberhard Wolff triggered us to reflect on these concepts and explore a bit based on things we have seen in practice.
