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
During the system testing phase a tester from your test team observes a failure in the system under test and he/she decides to create an incident report. The incident report is currently in a “new” state, indicating it needs to be investigated.
Which THREE of the following information items can’t yet be present in the incident report?
Number of correct responses: 3

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
Which of the following answers represents an invalid sequence of states that can’t lead the bug report to the “Closed” state?

Test Management
You are performing a quality risk analysis for a CSCI (Computer Software Configuration Item) used to implement a CBIT (Continuous Built-In Test) module of a safety-critical system.
During the quality risk analysis you are trying to identify the ways in which failures of the CBIT module can occur, for each of them trying to determine the potential causes and likely effects, and the risk level (calculated as the product of three factors: severity, occurrence and detection).
Which of the following risk analysis techniques are you working with?

Test Management
Based on the historical data of 5 past and similar projects, you have calculated these average numbers of defects detected in system testing:
- for each 10000 LOC (lines of code), 200 defects
- for each person-month of development team effort, 49 defects
You want to use this information to perform estimation for a new project.
The project manager tells you that he/she has estimated 20000 new LOC for this new project.
Four developers work for four months on this project before system testing.
During system testing, 797 defects are discovered.
Assume that the system test of this new project is using the same amount of work as spent in the past projects.
Based on this information only, which of the following statement is certainly true about this project?

You can count on well-written requirements, but you can’t count on an adequate contribution of the stakeholders to the quality risk analysis. You have to mitigate the insufficient contribution of the stakeholders because the risk-based testing approach shall minimize the product risks. Your test team has one expert tester in security testing.
Which of the following test activities would you expect to be the less important in this context?

Test Management
Assume you are currently working on a project developing a system where functional requirements are very well specified. Unfortunately non-functional requirements do almost not exist.
You are the Test Manager. You have to choose a technique for test selection that allows testing of non-functional characteristics, especially reliability.
Which of the following techniques for test selection do you expect being most useful in this scenario?
Number of correct responses: 1

What is the basic concept of this license? [1]
Your Project Manager has challenged you to come up with a process improvement strategy using the IDEAL model.
Which step within the process defines the success criteria? [2]
