Critics of the ICE

ICE is sometimes criticized as being too subjective. The arguments are:

• if multiple people score an idea to test, they would all score it differently.
• the same idea might be scored differently by the same person at different times. This difference would then affect the final prioritization list.
• team members who wanted their tests prioritized could simply manipulate scores to get tests approved (though let’s face it, if you’re worried about this, you have bigger problems than the wrong tests being run).
