1. What is quality?

Activities focused on providing confidence that quality requirements will be fulfilled.

The degree to which a component or system satisfies the stated and implied needs of its various stakeholders.

The degree to which a component or system protects information and data so that persons or other components or systems have the degree of access appropriate to their types and levels of authorization.

The total costs incurred on quality activities and issues and often split into prevention costs, appraisal costs, internal failure costs and external failure costs.

24. A batch application has been in production unchanged for over two years. It runs overnight once a month to produce statements that will be e-mailed to customers. For each customer, the application goes through every account and lists every transaction on that account in the last month. It uses a nested-loop structure to process customers (outer loop), each customer's accounts (middle loop), and each account's transactions (inner loop). One night, the batch application terminates prematurely, failing to e-mail statements to some customers, when it encounters a customer with one account for which no transactions occurred in the last month. This is a very unusual situation and has not occurred in the years since this application was placed in production. While fixing the defect, a programmer asks you to recommend test techniques that are effective against this kind of defect.

34. You are working as a project manager on an in-house banking software project. To prevent rework and excessive find/fix/retest cycles, the following process has been put in place for resolving a defect once it is found in the test lab:

1. The assigned developer finds and fixes the defect, then creates an experimental build

2. A peer developer reviews, unit tests, and confirmation tests the defect fix on his/her desktop

3. A tester- usually the one who found the defect- confirmation tests the defect fix in the development environment

4. Once a day, a new release with all confirmed defect fixes included, is installed in the test environment

5. The same tester from step 3 confirmation tests the defect fix in the test environment

Nevertheless, a large number of defects which the testers confined as fixed in the development environment (in step 3) are somehow failing confirmation testing in the test environment with the resulting rework and cycle time outcomes.

You have the highest confidence in your testers, and have ruled out mistakes or omissions in step 3. Which of the following is the MOST likely part of the process to check next?

The activity of developers, who may not be adequately testing in step 2

The activity of testers, who may be confused about what to test in step 5

The activity of developers, who may not be fixing defects properly in step I
