Quality 10 soal (Chapter 8)

Quality is:

• Meeting and exceeding the customer’s expectations

• Adding extra to make the customer happy

• The degree to which the project meets requirement

• Conformance to management’s objectives

Cost of quality includes all costs incurred over the lifetime of the product by investing in the prevention of nonconformance to requirements, appraising the product or service for conformance to requirements, and failing to meet requirements. Which is NOT an example of the cost of non-conformance?

• Rework

• Scrap

• Liabilities

• Destructive testing loss

Rachel have joined an ongoing project. This project is in trouble, so Rachel identifies the issues which have the highest effect on the project, and now she is analyzing the reason for these issues.

Which tool is Rachel using now?

• Fishbone diagram

• Pareto diagram

• Scatter diagram

• Tornado diagram

During the review of a control chart, you observe that the limit for one deliverable is below the lower control limit but above the specification limit.

What will your next step be?

• As it is within the specification limits, no action will be taken

• You will take corrective action

• You will replace the product

• You will adjust the control limits

Quality and grade are not the same. A fundamental distinction is that:

• Quality as a delivered performance or result is the degree to which a set of inherent characteristics fulfills requirements; grade as a design intent is a category assigned to deliverables having the same functional use but different technical characteristics.

• A quality level that fails to meet quality requirements may not be a problem; a low grade of quality is always a problem.

• Delivering the required levels of quality is not included in the responsibilities of the project manager and the project team.

• Delivering the required levels of grade is not included in the responsibilities of the project manager and the project team.

In relation to control charts, what are the upper and lower specification limits based on?

• The requirements, reflecting the maximum and minimum values allowed.

• The control limits.

• The specifications, reflecting the maximum and minimum values allowed.

• The requirements and control limits.

An automotive designer uses a certain technique to determine which combination of suspension and tires will produce the most desirable ride characteristics at a reasonable cost. To do this, the designer employs a statistical framework and systematically changes all the important parameters instead of changing the factors one at a time. This method is known as:

• Design of experiments

• Nominal group technique

• Statistical sampling

• Cost of quality

Rinaldi has been working in a manufacturing project as a project manager. This project is intended to produce high-quality microprocessor to use in computers. Since microprocessor are produced from silicon wafers, he contracted a company to provide silicon wafers to the project on an ongoing basis. For unknown reasons, the contractor provided low-quality wafers to the project, compromising the electrical performance of the microprocessor. Overwhelmed by complaints from the computer division, Rinaldi is now obligated to correct the manufacturing defects to avoid future liabilities. In this scenario, the costs incurred to Rinaldi are:

• External failure costs of Cost of nonconformance

• Prevention costs of Cost of conformance

• Internal failure costs of Cost of conformance

• Appraisal costs of Cost of nonconformance

A project was randomly selected for a quality audit, and the external auditor found various issues and nonconformance. The project manager lodged a complaint with the quality department that this was improper procedure, and he should have received notice since an external auditor was involved. What is your view?

• The project manager has no case. Quality audits may be random and performed by internal or external auditors

• The project manager is correct. Quality audits need to be scheduled when an external auditor is involved so that the project manager has time to prepare for them

• The project manager is correct. The project team must perform all quality audits

• The project manager has no case. Quality audits are always carried out by external auditor

You have undertaken a project under contract, where you are supposed to create an anti-virus software product for a customer in ten months. You follow the software development life-cycle which includes analysis, high-level design, coding, testing, and rollout, with a deliverable at the end of each phase. Your customer has defined the scope very well and said that he is going to review your product after ten months. What you should do next?

• Ensure that the customer should verify the deliverable at the end of each phase

• Ask your senior management to review the deliverable at the end of each phase to ensure that the deliverables satisfy customer requirement

• Complete the product as per specifications and provide the completed product to the customer as requested

• Provide project deliverables to the customer at the end of each phase, and wait customer to review them after ten months
