For the 10 ideas shortlisted, go to each idea and select the attributes associated with it.
Draw a table with attributes on one axis and ideas on the idea. The table should look somewhat like this.
Select the 3 ideas which have the most attributes. In our table above, they are ideas 5 (most), 8 and 4. Selecting the idea with the most attributes gives you the best choice to further develop it. It also means that these ideas are the ones in which you have the greater interest and are frequently in your thoughts.
