Mind mapping
• Mind mapping is the process of generating ideas and
developing concepts when the underlying relationships are
unclear

Procedure
• Identify the focus word or question
• Free associate outward from the focus
• Reorganize as needed
• Annotate

Criteria for successful use
• The designer must possess, or have access to people with,
strong domain knowledge
• Relies on early insight into the design problem, and what
dimensions might matter
• One should not dismiss ideas (generate first, consolidate
later)
• Collaborate

Strengths and weaknesses
Strengths
Weaknesses
• Can be used for many different
purposes
• Fluid representation suitable for
tool use
• Builds common understanding
and language
• Encourages idea generation
• Can uncover ‘hidden’
relationships
• Lightweight
• May become too disconnected
from reality
• May become too unwieldy in size
and complexity
• Generation of ideas is restricted
by the hierarchical form of
representation
• Requires a well-trained
moderator

Design studio 3
• Venture capitalist V has come to UC Irvine, seeking to upstage
the online note taking world
• The venture capitalist knows that, rather than through her
proposing the kind of app she wants, she is better served by
running this as a competition and getting a broad range of
ideas from which she then can choose
• V is particularly interested in forward thinking apps; apps that
will really make a difference 2-5 years from now

Design studio 3
• Your team is tasked with designing a novel note taking,
sharing, and organizing app that explicitly aims to upstage
existing apps in this space

Today
• Use the mind mapping design method through the use of
silent sticky notes

Design studio 3 continued
• Hand in a document, at the beginning of class, December 3,
containing your final design for the new note taking
application
• Team assignment
• Bring one copy
