What are the factors to be considered before resolving a proposed change in project?

Project team should consider the following factors when it decides how to resolve a proposed change:

What is the expected benefit of the change?
How would the change affect the project's cost?
How would the change affect the project's schedule?
How would the change affect the software's quality?
How would the change affect the project's resource allocation?
Would it add work to people already on the project's critical path?
Can the change be deferred to a later stage of the project or a later version of the software?
Is the project at a point when making the change would risk destabilizing the software?
