Overall, there is a strong sense ofteam. The manager suggests that the project manager does not have enough time to hold meetings about quality when the schedule is so compressed. Which ofthe following best describes why the manager is wrong?

• Improved quality leads to increased productivity, decreased cost effectiveness, and increased cost risk.

• Improved quality leads to increased productivity, increased cost effectiveness, and increased cost risk.

• Improved quality leads to increased productivity, decreased cost effectiveness, and decreased cost risk.

Qp.ality is:

• Meeting and exceeding the customer's expectations

• Adding extras to make the customer happy

• The degree to which the project meets requirements

All the following are tools and techniques of Control Quality except:

• Inspection

• Cost of quality

• Histogram

• Cause-and-effect diagram

Aproject manager is experiencing a great deal offrustration because a lot ofrework has been required. It seems as though the team has significant differences of opinion related to interpretation of the requirements. The project manager is trying to determine what changes need to be made to meet the quahty requirements and reduce future rework. He seeks the advice ofhis manager, who asks ifhe has

created a histogram. Histograms help the project manager:

• Focus on the most critical issues to improve quality.

• Focus on stimulating thin.king.

• Analyze the cause ofa quality problem.

• Determine if a process is out ofcontrol.

A control chart helps the project manager:

• Focus on the most critical issues to improve quality

• Focus on stimulating thinking.

• Analyze the cause ofa quality problem

• Determine if a process is functioning within established metrics

produce a new tool that will be used in restaurant kitchens. The project team has included random sampling of these tools in their quality plan. Although cost is a key factor, the product must also meet high quality standards. All the following are examples ofthe cost ofnonconformance except:

• Rework

• Quality training

• Scrap

• Warranty costs

When managing a change-driven project, how do you ideally want any coding errors to be identified and corrected?

• 1he QA team finds the errors during alpha testing

• 1he developers find the errors in automated unit testing

• 1he customer finds the errors when reviewing the product increment.

• 1he users find the errors on the first day ofrelease.
