Description Long

“Quick and Dirty Prototyping” can be carried out within a short time frame (around 15 minutes). This method enables the rapid visualisation of an idea or concept, helping to clarify its function and identify potential limitations.

The main “Imagery Modelling” phase takes between 30 and 60 minutes and involves creating a tangible model that brings abstract ideas to life. The focus is on expression, the creative process, and subsequent reflection in order to communicate goals and values more clearly.

If additional time is available, the “High-Speed Design Process” can be used. It consists of five phases: Exploration: Current practices are analysed through user interviews to gain a clearer understanding of the target group’s workflows. Visioning: Goals and obstacles related to the use of the new product are identified. Hypothesis Generation: A guiding question is developed to form a vision for an improved product. Testing: Five solution ideas are sketched, presented, and refined based on user feedback. Communication: A prototype is developed, tested, and evaluated by the target group to support further improvements.

Preparation

• Provide creative materials and workspace
• Clarify the method’s purpose and process

Execution

Within a short time frame, “Quick and Dirty Prototyping” can be carried out. In this process, an idea or concept is presented in a way that others can understand and grasp its intended function. It is a rough version of the idea, allowing those involved to recognise its limitations. The activity is carried out under time pressure, typically within around 15 minutes.

In the actual “Imagery Modelling” phase, a tangible model on a chosen topic is created within 30 to 60 minutes. This process brings to light implicit assumptions and perceptions about abstract concepts. The focus is not on what can be “recognised” in the models, but on what they express. The creation process, personal positioning, and critical reflection are key elements. Through modelling, a visual representation emerges that helps communicate goals and values more clearly.

If more time is available, the “High-Speed Design Process” can be applied. Here too, the idea is modelled using simple materials. However, the interests and needs of the target groups are explicitly included – for example through interviews or focus groups, which require more time. The process is structured in five phases:

1. Exploration: How is the existing practice carried out, which the newly designed product aims to improve? Activities of the target group are reconstructed through user interviews.
2. Visioning: The goals and motivations associated with using the new product are summarised. What supports the target group in using it – and what stands in the way?
3. Hypothesis Generation: Based on the vision, a guiding question is formulated to inform the development of an improved product.
4. Testing: Five possible solution approaches are sketched and presented to users. Their feedback is collected and used to refine the ideas.
5. Explaining and Communicating: One option is selected for prototyping. The prototype is then created and evaluated by the participants. What works well? What needs improvement?
