CSQE Exam Questions & Answers

Earned Value Management (EVM) includes several key metrics, one of which is the budgeted cost of work performed (BCWP). Here's a detailed explanation:

Earned Value (EV): Represents the value of work actually performed in terms of the budget assigned for that work.

Planned Value (PV): The budgeted cost for the work planned/scheduled.

Actual Cost (AC): The actual cost incurred for the work performed.

Performance Measurement: BCWP is crucial for comparing planned work with actual progress and costs, helping in performance measurement and project forecasting.

The phrase '80% coverage' in testing typically refers to the percentage of statements in the program that have been executed at least once during testing. This is known as statement coverage or code coverage. It is a measure of how much of the code has been exercised by the test suite and is used to assess the thoroughness of the testing efforts. It does not necessarily mean that 80% of the software is error-free, that 80% of planned test cases have been completed, or that 80% of predicted errors have been uncovered, although higher coverage often correlates with better defect detection.

A successful internal audit depends significantly on obtaining management's cooperation and support. This ensures that the audit findings and recommendations are taken seriously and that there is a commitment to implementing necessary changes. Reporting deficiencies, completing checklist items, and recommending corrective actions are important, but without management support, these actions may not lead to effective improvements. Reference: 'The Internal Auditing Handbook' by K.H. Spencer Pickett.

The class intervals 11.5-13.5, 13.5-15.5, 15.5-17.5, and 17.5-19.5 are appropriate for representing the given data set in a histogram. These intervals cover the entire range of the data, ensuring each data point falls within a specific interval, and they are consistent in width, which is crucial for accurate histogram representation.

For safety-critical software, it is crucial to specify how the system should react to accidents or hazardous conditions to mitigate risks and ensure safety. This type of requirement directly addresses safety concerns by defining specific actions that the system must take in response to potential safety issues.
