Tools & more

explore and try out

Change Punk thinking tools help you approach organizational change with “radical honesty” – especially when you’re under pressure, resources are scarce, and quick results are required. Here are three of our favorites.

Tool for better decision-making

Decision Canvas

What exactly is important, i.e., what needs to be decided and why - and what doesn't? This one-pager with its ten questions helps define objectives so that everyone understands and actively supports them.
Tool for clear roles

Decision Hats

Who should, can, and wants to decide... who else needs to be involved... and how? These playing cards help clarify roles in decision matters and avoid misunderstandings and conflicts.
Tool for effective implementation

Project Canvas

The 42 questions help to understand new initiatives in a structured way, so everyone knows what's important, why it matters, and how to get things moving together. It brings you on the same page, heading in the right direction.
Talk to us to learn more about our tools. All tools come from our own research center 'Over the Fence.' Karen founded this together with Prof. Dr. Frank Habermann in 2013 to revolutionize change and management.

We've also written articles and books. Highly praised, fiercely competent, but colorful! Here are our bestsellers.
