We all have been reading headlines and articles about cars that have been recalled due to certain failures, and the numbers of cars that needs to be delivered to local car shops are always quite high. A quick Google search shows articles like BMW recalls 300.000 cars , Kia recalls 500.000 cars , Fiat recalls 4.8 million cars , this list could be as long as you want it to be. Recently Tesla's model 3 were tested by Consumer Reports , a nonprofit organization providing product ratings and reviews, and they ended up not recommending this model due to issues with Tesla's stopping distance which were almost 50 meters when braking at about 100 km/h. This was far worse than any contemporary car tested by the magazine and about 2 meters longer than the stopping distance of a Ford F-150 full-sized pickup .  Tesla, instead of recalling this model, which has more than 400.000 pre-orders (at this point I was not able to find out how many were already sent out from the factory), they p...

This week I have been looking a bit into whether language(s) we speak, shape the way we think? Being raised up bi-lingual from the age of 8, where I spoke mostly Bosnian and Norwegian with a good addition of English, this is quite an interesting topic for me personally. Inspired by a talk from Lera Boroditsky from TEDWomen 2017, who had done a lot of experiments on this, here is what I found out. If you find this interesting, I encourage you to take a look at the presentation, many examples that I mention here are taken from her talk. 7000 languages, different way of thinking? There are about 7000 languages, each different from one another, in many ways, different sounds, different vocabularies, not at least different structures, to mention a few differences. Whether a language affect how we think has been debated throughout the centuries. "To have a second language is to have a second soul", stated Charlemagne, which is quite a bold statement suggesting that language is ...

So where to shift now that testers are part of reviewing the business cases, participate in creation of user stories and backlog grooming, have the ability to use monitoring in different environments, and everything in between, meaning participate in different parts of the software development and delivery life cycle? Well, I think that we could benefit a lot from trying to look at where we generate mistakes. If we sum up the development life cycle, regardless of how often you release, or whether you follow a  waterfall, agile, or devops approach, it all starts with some ideas, business cases, requirements on a higher level, before going into the process of refining the requirements, developing, testing and releasing the changes to the end-users. We previously shifted left and right trying to mitigate and correct issues that occur along the way in the process, without looking into where these mistakes originated. All of the ideas or requirements start in someones mind, with all...

Some time ago I read the book "Thinking Fast and Slow" by professor and Nobel prize winner, Daniel Kahneman, which is about the biases in our intuition, that we assume certain things automatically, in an instant, without having thought through them carefully. In many situations it is perfectly fine to act instinctively, but in others we should activate rest of the mind. In this blog post I will try to relate some of the topics that he touches upon in his book, to our field of software testing and development. My initial idea was that I would fit most of the topics into this blog post, but upon revisiting the book, I feel that there are way too many topics of interest covered in his book, and by going into all of them, this blog post would most likely result in another book, rather than a blog post. So I will only cover some of the topics. If you have not read his book, find it and set aside some time to read it. Read it fast and slow, it is truly an amazing book with a...
