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?

Assume you are the Test Manager in charge of independent testing for avionics applications.
You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):
- a BOOT-X CSCI that must be certified at level B of the DO-178B standard
- a DIAG-X CSCI that must be certified at level C of the DO-178B standard
- a DRIV-X CSCI that must be certified at level A of the DO-178B standard
These are three different software modules written in C language to run on a specific hardware platform.
You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.
Since there are significant budget constraints to purchase this tool, you are evaluating an open-source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).
The source code of the tool is available.
Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.
Which of the following are the three main concerns related to that open-source tool selection?

Assume you are a Test Manager involved in system testing of a CRM application for a Pay-TV company. Currently the application is able to support a proper number of users assuring the required responsiveness. Since the business is expected to grow, you have been asked to evaluate the ability of the application to grow to support more users while maintaining the same responsiveness.
Which of the following tools would you expect to be the most useful at performing this evaluation?

You are managing the system testing for a SOA based system. The integrated system consists of several subsystems:
- A SOA middleware
- A CRM (Customer Relationship Management) system
- A BRM (Billing and Revenue Management) system
- A SMS (Subscriber Management System) system and you performed a risk analysis based on these subsystems.
At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue:
In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04.
Which of the following subsystems, based on the risk scores of the table, is most risky?

Consider the following skills assessment spreadsheet for your test team (consisting of four team members):
This spreadsheet has three sections: technical expertise, testing skills and professionalism.
The skill levels for each skill area for both the “technical expertise” and “testing skills” sections have been rated on a four-point scale:
- E (Expert): indicates that a person has expert knowledge and experience in the skill area
- B (Beginner): indicates that a person has some knowledge and experience in the skill area but he/she is not autonomous
- W (Wants to learn): indicates that a person has no knowledge or experience in the skill area but he/she wants to learn that skill
- NI (Not Interested): indicates that a person has no knowledge or experience in the skill area and he/she is not interested to learn that skill
The skill levels for each skill area of the “professionalism” section have been rated on a three point scale (H=High, M=Medium, L=Low).
Consider the following analysis of testing skills performed on four peoplE. Alex, Robert, John and Mark (all the skills have been rated on an ascending scalE. The higher the score, the better the skill):
Which of these people, based on this analysis, would you expect to be most suitable to work specifically as test designer?
