Representations

tool description

The affinity diagram is a creative process used for gathering and organizing large amounts of datas, ideas and insights by evidencing their natural correlations. It starts with a statement of the problem or the goal.
During the first session each participant should think of ideas and write them on small pieces of paper (cards or stickers). Then those cards would become the physical instrument to work on their contents, find the correlations and identify the significant groups of sense.
The result is a sort of verbal and visual representation describing the first exploration of design solutions.

SERVICE DESIGN FOR AIRPORT SECURITY

Jamin Hegeman, Kipum Lee, Kata Tennant (Carnagie Mellon University)

This project dealt with the ideation of a service that will foster flow at the Transportation Security Administration (TSA) security screening stations at the airport.
As first step the team decided to observe what happens at the Pittsburgh International Airport; after the observation, the findings were switched into notes on post-it and diagrammed according to their affinities. This allowed the team to determine the three main design principles: communicate to passengers, feel in control and say goodbye.
