From Pyramid to Pancake is the symbolic name I came up with for the change that society in general and organisations are becoming flatter structures. Push and pull for this change is the way we are enabled by technologies like social media and SaaS/Cloud.
Below you will find a (long) presentation with some ideas on this.
Below you will find a link to a mind-map that sort of collects my ideas to do my research. This is a work in progress and new information will be added regularly.
You can find this mindmap here (this is a fixed version readable from the web).
