Defect Management
Assume you are working on a defect management process to be used by a software organization to track the current status of the defects reports for several projects.
When a defect is found for investigation a defect report is created in “Opened” state that is the unique initial state. The defect report status has also a unique finale state that is the “Closed” state.
The following state transition diagram describes the states of this defect management process:
where only the initial (“Opened”) and final (“Closed”) states are indicated while the remaining states (V, W, X, Y, Z) have yet to be named.
Which of the following assignments would you expect to best complete the defect management process?

Defect Management
Consider a defect report and assume that a part of its lifecycle includes the following states:
New: Is the initial state
Working: Means that the developers are addressing the defect in order to produce a fix for the defect
Clarification: Means that the developers need more information from the tester to address the defect and produce a fix for the defect and the tester is working to provide this information to the developers
Verification: Means that a fix for the defect has been produced and the tester is running the adequate tests to verify whether the fix solves the defect
Closed: is the final state

Testing Process
Assume you are the Test Manager for a new software release of an e-commerce application.
The server farm consists of six servers providing different capabilities. Each capability is provided through a set of web services.
The requirements specification document contains several SLAs (Service Level Agreements) like the following:
SLA-001: 99.5 percent of all transactions shall have a response time less than five seconds under a load of up-to 5000 concurrent users
The main objective is to assure that all the SLAs specified in the requirements specification document will be met before system release. You decide to apply a risk-based testing strategy and an early risk analysis confirms that performance is high risk. You can count on a well-written requirements specification and on a model of the system behavior under various load levels produced by the system architect.
Which of the following test activities would you expect to be the less important ones to achieve the test objectives in this scenario?

Improving the Testing Process
Consider the following statements describing the importance of improving the test process:
I. Test process improvement is important because being focused only on the test process it can provide recommendations to improve the test process itself, but it can’t indicate or suggest improvement to areas of the development process
II. Test process improvement is important because it is much more effective than software process improvement to improve the quality of a software system
III. Test process improvement is important because several process improvement models (STEP, TPI Next, TMMi) have been developed over the years
IV. Test process improvement is important because every organization, regardless of the context, should always achieve the maximum level of maturity of testing described in the test improvement models such as TMMi

Reviews
You are a Test Manager working for a software organization where reviews have never been applied. After a meeting with your managers examining a business case for reviews, (including their costs, benefits, and potential issues), the management finally decides to adopt formal reviews for future projects.
