What is this tool and what is its purpose and benefit?


Concept visualisation helps to translate an idea into a visual form as a concept for presentation and communication, making it quick and easy to understand. It is based on a narration that explains and justifies the concept and its details. Therefore, text can be used to support the visualisation.

Steps how to use this tool in practice

The same steps apply when working individually, in pairs or in a group.


Take the idea or ideas that you want to combine into a concept and think about the justification and idea behind the concept, what is the identified problem, the causes for the problem and the solution you propose.


Write down the key features and details of your concept including those that make the essence of your idea.


Visualise the concept.


Present your story to the target audience you have identified.


Evaluate their feedback and check if there are any changes that need to be introduced to your concept.
