Signs of a failing project

An abbreviated version of the list from Bob Lewis's excellent column, Keep the Joint Running:

Goals The goals no longer make business sense
Scope The scope keeps expanding
Plan Tasks are "stuck" at 80%; tasks take over a month; or no task planning at all!
Optimism Project manager "hopes" everything is going well
No demo Can't produce a working demo by the appropriate point in the project
Testing Continuous testing and bug lists aren't shrinking
Team The team members want the project killed

What to do based on how many symptoms are noted:

1 or 2 Fix the problems
3 or 4 Conduct an external review
5 or more Kill the project
