1. Good tests are the best documentation

    Reading time: 4 minutes

    Why do you test? Is is because you want to prevent errors on a deployment affecting the visitor? Is it because you simply want to know that the software does what it needs to do? Or maybe you want to get to know the software a bit better?

    Hopefully, in this day and age, your main software tests are automated. Running before a commit, running in the deployment pipeline and running on a testing environment. Repetitive jobs need automation and testing fits that mantra very well. This article is relevant for automated testing, although for certain topics you could use a manual testing perspective as well. If you like.

    So. You’re a small, medium sized or even large scale company. IT is an integral part of your business, whether it is a small scale application or an enterprise grade platform. Let me repeat that for you: IT is an integral part of business. You know this, because you’ve been doing IT for a long time, right? But. Are you doing it right?

    Yes, you tick the SEO boxes and yes, off course you’re in the cloud (whatever the heck that is). You have backups 🤞. Nice! You even have a couple of scrum teams working together on your product. Extra nice!

    I am working for Jumbo Supermarkten, which is a large grocery chain in the Netherlands. This family owned business started to venture into e-commerce at about 10 years ago with a very small team of developers. Currently, we've grown into an IT department that consists of over 450 developers working on all digital solutions. We've made some changes over time on how we manage our software. I gave a talk together with my colleague on this topic, so let's share the write up here.

    So, if we rewind the clock the the founding of the Jumbo Tech Campus (JTC), where in the beginning the main purpose was to get started with e-commerce. What happened was that the team at the time did the thing that is most obvious with limited resources and a generic goal: they grabbed an off the shelf solution and started to implement it. This meant connecting to the existing brick and mortar stores, the delivery and storage APIs and whatnot.

  4. Broken windows

    In software engineering, we can apply a lot of the psychology findings to their digital counter part. If we consider the broken window theory, it doesn't apply to the operating system, but to the state of code.

    Let's go back to the source. From an article originating from 1982 ("Broken Windows") in The Atlantic by James Wilson and George Kelling.
