QWAN - Quality Without a Name

Our Services

Consultancy and 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!

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

-A course participant

“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.

Logical vs Deployment Architecture

13 October 2020

When we visit clients and discuss the architecture of their software systems, we often notice that people conflate different concerns under the term ‘architecture’. They tend to mix logical concerns with deployment concerns. Examples of logical concerns would be domain logic, domain dynamics, and how these are connected. Deployment concerns can be for instance REST APIs, components, microservices, and lambdas. The recent ‘cloud native’ movement has made this even worse, especially with serverless infrastructure concepts.

Test Data Builders

09 October 2020

Imagine you grow a suite of automated tests that serve you well, but you are struggling to read through them. Quite a bit of repetition and boilerplate that obfuscates what is going on in individual tests. Builder is a pattern that lets our tests reveal their intent more succinctly, at the cost of making a small investment in creating a builder for our domain concept under test.

Test driving a command line interface in Python

07 October 2020

Testing a command line interface (CLI) should be just like testing a REST interface. A CLI is an adapter concern that we can test drive, separate from the business logic. In this post I’ll show an approach to test drive the command line interface of an application in Python.

Dimensional Planning - a story

30 September 2020

In this post, we will explain how Dimensional Planning can work by sharing a story of how we applied it in a project and how it helped us to steer the project towards delivering its desired outcomes in time.
