** qualitative method
 
** based on open interviews (no questionnaires)
 
* Further information on this method is available, see:
 
** The book (rosenfeld media) [http://rosenfeldmedia.com/books/mental-models/ Mental Models]
 
** excerpts available for online reading [http://paperc.de/18382-mental-models-9781457102301#!/pages/1 via paperc] (German website, book in English)

====Connection to Exsiting Research====
 
* using [[User Scenarios]] as a hypothesis for audience segmentation
 
* [[GIMP UI Redesign#functionality overview|functionality overview]] will be confronted with users' perspective
 
 
 
====Course of Actions====
 
# define audience (already existing: [[User Scenarios]])
 
# recruit participants, set scope and conduct interviews
 
#* at least 4 interviews per audience segment
 
#* focus: tasks, behaviours and philosophies of users
 
#* transcribe interviews
 
# analyze results
 
#* distillation of tasks, behaviours and philosophies into patterns
 
#* create graphic of patterns in a mental model
 
#* oppose mental model vs. planned and existing functionality
 
# make use
 
#* gap analysis (planned and existing functionality vs. users' behavior, needs and tasks)
 
#* adjust user scenarios / audience segments
 
#* derive stragety for development
 
#* prioritize features (importance vs. feasability)
 
 
 
====pros and cons====
 
*(+) pros
 
** fundamental research, broad focus, high-level
 
** detailed analysis of users and their tasks
 
** research is built on existing findings
 
** verification of user scenarios / audience segments
 
** based on tasks and behavior
 
** adaptable / scalable method
 
** supports strategic vision and long-term development
 
** revision and clarification of user scenarios
 
 
 
* (-) cons
 
** fundamental research, broad focus, high-level
 
** no immediate improvements
 
** complex method
 
** not all existing findings are considered
 
 
 
===Deliverables===
 
* primer (20-40 page pdf about users, tasks, context)
 
* Mental Model Diagram
 
** one diagram per audience segment
 
** tasks organized in "Mental Spaces" of users
 
** justified audience segments based on tasks
 
** gap analysis
