“Designers work iteratively to test their ideas and improve them throughout the entire development process. Making an idea tangible from an early stage through cheap mock-ups helps save resources and can minimize risk. Few advices for a solutions design prototyping here.
Prototyping can be applied to both products and services, and allows real world feedback from users that ensure better, more relevant outcomes. It can be quick and cheap and allows a solution to be iterated and improved before it is rolled out.” (UK Design Council, Design methods for developing services, 2014)
So the idea behind prototyping is making thoughts visible and concrete. Prototypes have to exclude bad concepts from the service and focus on the most promising ones.
This is a list of questions prototyping should answer:
• Does the specific solution work?
• Is the service desirable from the consumer’s perspective?
• Is the service easy to consume and deliver?
• Is the service economically and strategically viable for the service provider?
Presentation of the results sometimes also requires several tries to find the right way to highlight the main idea clear way. In the example below bubbles diagrams (by width and area) looks attractive but they are not friendly for a comparison of the values. Therefore they don’t accomplish the main task to present capacity distribution between current and target tiers.
The second bar chart prototype gives a much clear understanding of the findings.
Prototyping is User-centric,
Co-creative and Evidencing .
Prototyping is about testing. Also, it is “a vehicle for dialogue” (Kodrat, Liem, & Kusumowidagdo, 2011). It has to provoke service participants for a conversation. Sometimes people can’t start to discuss abstract ideas. A tangible prototype can trigger and direct such discussion that by turn generates more upfront activities and ideas how to solve the problem and satisfy the customer.
