5. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 5 Mind mapping Mind mapping is the process of generating ideas and developing concepts when the underlying relationships are unclear

6. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 6 Procedure Identify the focus word or question Free associate outward from the focus Reorganize as needed Annotate

7. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 7 Example: identify the focus word or question

8. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 8 Example: free associate outward from the focus

9. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 9 Example: reorganize as needed

10. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 10 Example: annotate

11. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 11 Typical notation: mind map

12. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 12 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

13. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 13 Strengths and weaknesses Strengths 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 Weaknesses 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

15. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 15 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

16. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 16 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

17. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 17 Today Use the mind mapping design method through the use of silent sticky notes

18. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 18 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
