Which scope model is best?

Wysocki focuses on the "Scope Triangle", some sources present four criteria:

• Time
• Cost
• Resources
• Quality

Consider this viewpoint vs. the "Good/Cheap/Fast" perspective:

• Which model do you prefer, and why?
• Is there really any practical difference between the models? If so, what is the difference?
• Are there any additional criteria that you think should be added to produce a more effective model?
