The Microwave With Feature Creep

Hi, My microwave was broken. So: I need a new one. However, I have a little quirk when it comes to buying anything that’s not perishable. I want to avoid making a bad purchase. I’d rather spend more money once than have to buy a new one in two years. Here, I have to be careful not to fall down a rabbit hole. I can spend hours reading reviews.

What Sound Does Your Microwave?

Hi, Do you know the feeling? You turn on a device that you use over and over again. For years. You recognize the sound it makes. The rhythmic “whoosh whoosh whoosh”, when you start the dishwasher.

But what does this have to do with the question from the beginning? An application goes beyond this.

The Fourth Ideal: Psychological Safety

Hi, Last week, emotions were running high. One of my clients achieved something extraordinary. They have successfully operated a product for 10 years. Highly profitable. But the project was not started by trained developers. It began as a side product. The initial developers were career changers. Highly interested, motivated, engaged, and experts in their domain. And they accomplished something that fails in 9 out of 10 cases. Their product is actively used.
