I want to add few more characteristics to the list:

1. Consistent: doesn't contradict other requirements.

2. Unambigous: Each requirement must have one and only one interpretation.

3. Verifiable: Stated requirement is not vague or general but is quantified in a manner that can be verified by one of the following 4 alternative methods:
a) Inspection
b) Demonstration
c) Analysis
d) Test

-complete. Is anything missing or forgot?
-Accurate. Is the proposed solution is correct?Does it properly define the goal?

-precise, unambiguous, and clear. Is the description exact and not vague? Is it easy to read and understand?
-Consistent.Is the description of the feature written so that it doesn't conflict with itself or other itemsin the spec.
-Relevant. Is it extra information that should be left out? Is the feature traceable to an original customer need?
-Feasible. Can the featurebe implemented with the available personnel, tools,and resourceswithin the specified budget and schedule?
-testable. Can the feature be tested? Is enough infomation provided that a tester could create tests?

A Good Requirement should be

1. Unambiguous- Are the definitions and descriptions of the required capabilities precise?
2. Complete - Are there any gaps or omissions?
3. Consisent - Free from Internal and external contradictions?
4. Implementable - Can the requirements be realized in practice?
5. Testable - Can the requirements be tested effectively?
