meta - Overview of various Prototyping methods.

I have been very intensively involved with all the lean methods and books about product development. I wanted to know everything and design the ultimate prototype process. Unfortunately this was not possible. However, it was possible to arrange and categorize all methods and tools in this area on a meta-view.

thesis - Software as a Service to formulate hypotheses and define experiments.

I am currently working on a software service to formulate refutable business hypotheses and to validate them automatically by means of experiments. Currently the product is still under development, updates are regularly available in the newsletter.

The underling Philosophy & Manifesto

Good software is always used but never finished.

The goal is to always build the next v01. In software and in life. Zen philosophy puts it like: Nothing exists in its present form or color except in this moment. A beginners mind is free of any possessions, as it knows that all is in a state of fluid change.
