Tips to Make the Best from Insight Tree

Try the following:

Use Insight Tree with a data projector in a team meeting when it comes to joint decision making. You will find that it is often much easier to come to a solution to which everybody can agree.
Insight Tree used in a workshop is also a good way to avoid the Abilene Paradox, a situation in which a group makes a decision which no group member really wants, but each member wants to respect unspoken (and actually not existent) wishes of the other workshop participants.
Use external links to an Excel workbook if some of the monetary data should be visible for another person and some not. Remove the Excel source file and the other person will not have access to details laid down in them but will still be able to see the numbers in Insight Tree.
