One of the main uses for Mapit is in helping with rapid decision making.  This could be when the user is operating out of their usual experience.  For example night desk staff answering the phone at a hospital, new or temporary staff in a new role.  Or for the case where an expert has captured their knowledge and experience into a sequence of steps – such as Dr Brendan Reilly at  Cook County Hospital Chicago who used experience and analysis to produce a simple 4 step decision tree for identifying true heart attack patients - see http://ebm.bmj.com/cgi/reprint/10/6/189.pdf .

If you have a decision process mapped out as a diagram such as

• for helping counter the threat of Trypanosomosis in cattle - http://www.smallstock.info/tools/disease-nutrition/6358.htm

• or for whether to use green power solutions in networks - http://www.gsmworld.com/our-work/mobile_planet/green_power_for_mobile/decision_tree/index.htm

• or a Food Safety training decision tree http://servsafe.osu.edu/tree.php

then you have a reason to use Mapit.

If you have a flow chart with any branching, and you want to ensure that who ever is to use that flow chart does not get lost, then use Mapit – when you are navigating through each decision page it keeps note of each question and answer so that when you have finished it will show you how you reached your decision.  Also as a user of the decision tree only sees one question at a time they cannot necessarily jump to a more ‘favourable’ branch if they see one.
