The indicators of a good UDE in individual work:

• Is the statement of the entity real to the person proposing it?
• Is it negative in the mind of the "proposer"?
• Is it within the proposer’s area of responsibility?
• Is it considered to be of importance to remove it?
• Does it exist?

When working as part of a group, ask also:

Is it negative in the mind of the group?

Ensure that the UDE is verbalised as a full sentence.
