Make Better Decisions This Year

Last christmas I wrote a couple of articles for Bekks advent calendar. This is an English translation for my Norwegian 🇳🇴 post titled Prøv OST før jul, enjoy!

“Would you like to write an article to be published on Christmas Eve, Runar?” “Yes!”, I said. “Future-Runar can handle anything.” But was that a good decision? Read on and judge for yourself. Anyway, use the method I talk about below and make better decisions than past-Runar did.

As humans, we make decisions and choices all the time. Most choices are simple, and a select few are actually important.

For the simple ones, we have quick techniques like subconscious, gut feeling, and mental shortcuts, mixed with a bit of good old “I don’t care how it turns out” and luck. Such choices can be made quickly, usually turn out just fine, and life goes on. Fortunately.

The distinction between important and unimportant choices is primarily that we actually care about the outcome, and the consequences are significant or hard to reverse. For these important decisions, we want an effect, but the path there can be complex and unclear.

So what is a good decision-making process for important choices?

Introducing the decision ladder! Or actually, a great book written by Jan-Ole Hesselberg and Reidunnn Lognvik Reinholdt called “Better Decisions”. In the book, they describe just such a method for making better decisions. It doesn’t have to take a long time, but it contains elements that are useful to include in the process to ensure that the decision is based on what you know, not what you think.

The rest of the article explains the method, and I start with a picture of the ladder (as a repetition for new readers):

How to Deal with AI as a Product Team

In my article, How to Deal with AI as a Product Team, I explore the dynamic role of generative AI within product teams. I discuss how AI, like Large Language Models, can boost creativity and streamline tasks such as design and data analysis, while also highlighting the need to navigate challenges like data privacy and ethical considerations.

I emphasize a strategic approach for product development teams, stressing the importance of understanding user needs and integrating AI in a way that enriches the user experience. This article is a deep dive into finding that sweet spot where human creativity meets AI efficiency in product development. For a comprehensive understanding of how to skillfully integrate AI into product teams, read the full article here.

Cross-platform SwiftUI - challenges and solutions

Today’s article delves into the world of cross-platform development utilizing SwiftUI.

In this context, cross-platform refers to the ability to deploy a single app across multiple Apple platforms, leveraging a shared codebase written in SwiftUI. This approach, while efficient, presents unique challenges. The article aims to offer effective solutions, focusing on critical areas such as:

  • Layout and User Interface Adaptation: The key challenge in cross-platform development is achieving a UI that excels on all devices, for which SwiftUI’s ResponsiveView is essential; it dynamically adapts content to different environments, such as device types or screen sizes, using layout changes and environmental properties like size classes for a more responsive design.

  • Platform-Specific Features and Capabilities: Apple platforms, each with unique features and APIs, require tailored coding approaches in SwiftUI, like conditional compilation and the use of extensions and typealiases, to streamline cross-platform functionality and maintain focus on the app’s business logic.

  • Performance Optimization: Remember that the watch is a tiny supercomputer on your wrist, not a gargantuan supercomputer.

  • Working with Previews: SwiftUI’s preview feature significantly aids in cross-platform development by allowing developers to view real-time UI changes and validate how their app appears on various devices, using PreviewProvider and .previewDevice() to simultaneously preview the app on different platforms like iPhones and iPads.

What Does a Team Leader Actually Do?

Christmas is upon us, and, as per tradition, I’ve written a couple of articles for Bekks advent calendar. This is an English translation for my Norwegian 🇳🇴 post titled Hva gjør egentlig en teamleder?, enjoy!


Organizations, the team members, and roles vary greatly from place to place. Does the team have a tech lead? A product manager? Is the organization well-versed in digital product development? The answers to these and many more questions define the role of a team leader.

Additionally, the part of the role that happens outside the team isn’t always visible to those left behind when the team leader rushes off to meetings outside the team’s safe confines.

So, one fine day in Trondheim, at our team leader forum, we sat down and discussed what we see in this role. We had various perspectives, and the details varied, but the essence we came to is this:
