What is a product-led organization?

To indie game developer and back

A few months ago we noticed a message that stood out on our internal platform. Basically, it stated: "I'm back". Naturally, it happens every now and then that employees explore their horizons but still return to What this episode covers However, the number of software engineers that turn to indie game developer and come back, is quite limited. That sparked our curiosity since for a vast group of engineers it is some kind of dream job to develop games. That must have something to do with the large number of gamers among software engineers.

Transforming your experimentation knowledge into a book

We are not only the hosts of the show but so far we also do the selection of the topics ourselves. Research what’s interesting. Find diverse subjects and guests, etc. What this episode covers And sometimes guests make it easier for us. They post on our internal platform a message…. “What is the superlative of bragging? I don't think I can go any further than telling you that I co-wrote a book. And of course, it's about experimentation Yesterday I received the first copy in my hands, and it is of course for sale at ” The book is called “Steering on results”, how to work together on the greatest ambitions. Work smarter not harder. (So far only available in Dutch but English translation is being worked on). And since this week we know that the book is on the long list of books to become Management book of the year in 2022. A Dutch award organized by one of our partners (how can I check if this is true?) This triggered us in two ways: First – what is the book about? Learning by three elements Introduction of CRAFT: Create, Refine, Align, Finalize & Transmit (CRAFT)Introduction of Objectives, Progress Metrics & Estimates (OPME’s), in we refer to this one as OKR's.3. thorough research methods Second – How is it to start writing a book?
