the creating the macro plan includes;

estimating an effort distribution over a set of the triggers and a set of the activities;

estimating a defect distribution over the set of the triggers and the set of the activities; and

generating a schedule of the test project based on the effort distribution and the defect distribution.

2. The method of claim 1, wherein the creating the macro plan further includes generating a cost overview of the test project based on the effort distribution and the defect distribution.

3. The method of claim 1, wherein:

the creating the macro plan further includes permitting a user to specify a constraint; and

4. The method of claim 3, wherein the constraint comprises one of total effort and maximum field defects.

5. The method of claim 1, wherein the programming instructions are further operable to:

permit a user to adjust one of the effort distribution and the defect distribution; and

re-estimate the effort distribution and the defect distribution based on the adjusting.

6. The method of claim 1, wherein the creating the micro plan includes:

creating a system under test (SUT) model based on test requirements;

receiving annotations of the SUT model from a user; and

estimating a test case distribution for the SUT model.

7. The method of claim 6, wherein the test case distribution is based on a same set of triggers and activities as the macro plan.

8. The method of claim 7, wherein the annotations are related to aspects of use cases of the SUT model.

9. The method of claim 1, wherein the reconciling includes comparing at least one of effort, a number of test cases, and estimated defects between the macro plan and the micro plan.

10. The method of claim 9, wherein the at least one of effort, number of test cases, and estimated defects are defined in terms of activities and triggers.

11. The method of claim 1, wherein the reconciling includes:

presenting the deviations between the macro plan and the micro plan to a user; and

for at least one of the deviations, receiving from the user one of a confirmation of or an adjustment at least one of the deviations, wherein the adjustment comprises at least one of;

manually changing a number of test cases in the micro plan,

annotating a use case of the micro plan, and

creating a new test case in the micro plan.

12. The method of claim 1, wherein a service provider at least one of creates, maintains, deploys and supports the computing infrastructure.

13. The method of claim 1, wherein the computing infrastructure is provided by a service provider under a subscription and/or fee agreement and/or based on advertising content to one or more third parties.

14. The method of claim 1, wherein reconciling the macro plan and the micro plan comprises:

identifying deviations between the macro plan and the micro plan based on a comparison of the triggers;

presenting a user the deviations between the macro plan and the micro plan on a graphical user interface;
