Design Strategy for Mobile Handsets

April 9, 2011

Once a business strategy has been agreed, either you need an experience strategy to guide the detailed design of products, or you need at least some design principles to work from.

This is an extract (92Kb .pdf) from a paper I wrote to define the high-level design principles and overall UX strategy for our mobile handset products. Intended to be read by both the UX and Product teams, it forms a discussion document as well as a way of judging specific ideas that we may have in the future.

All  these  factors  are multiplied  when  correlated  with  the  past—that  is,  when  the  software  makes  use of  history. We  have  two  main ways  available  to  realise  this:  the  customer's  own  history,  and  the history  of  customers  who  are  not  her.  The  latter  technique  ("collaborative  filtering")  is  something  we should  always  consider,  but  as  the  customer  uses  the  application,  she  drops  many  clues  for  us.
