Because it is not so easy to juxtapose these frameworks, Jack decides to ask a few experts.
By talking to others, Jack discovers that S3 has a softer start. You can practice S3 by applying a few ‘patterns’. That appeals to Jack, since everyone in the company has to learn this. That way, they can move forward with very small steps.
With S3 you also only use what you find useful and you are free to adjust that if you think you can arrange it better. For example, if you want to delegate decision-making to roles in circles, you can apply that pattern. With S3 the starting point is that people have no objections. It is more about consent than agreement. In other words: decision-making based on consent.
Although a few names keep popping up as embodiments of the ideas of S3, nobody claims to have all rights over it.
