Objectives - Quality Control and Process Improvement

The main principles, purposes, and outcomes of quality control (QC) include:

• Ensuring products meet specified standards and identifying defects

• Maximizing production speed regardless of quality

• Focusing only on cost reduction without quality checks

• Ignoring customer requirements in the production process

The function and purpose of inspection in engineering and manufacturing is to:

• Ensure products meet quality and specification standards.

• Increase the speed of production regardless of quality.

• Reduce the cost of raw materials.

• Eliminate the need for skilled labor.

Process capability in the context of manufacturing is:

• A measure of a process's ability to produce output within specification limits.

• A method for increasing production speed.

• A technique for reducing labor costs.

• A tool for designing new products.

Which of the following best describes an advantage of 100% sampling compared to statistical process control (SPC)?

• It ensures every item is inspected, reducing the chance of defective products escaping detection.

• It is less time-consuming than SPC.

• It requires less labor and resources than SPC.

• It is more effective at identifying process trends than SPC.

Six Sigma is used for high volume manufacture by:

• Reducing defects and improving process consistency

• Increasing the number of product variants

• Focusing only on manual inspection

• Eliminating all automation in production

What does Quality Control (QC) implement in the manufacturing process?

• Marketing strategies

• Quality assurance inspection and testing requirements

• Financial audits

• Product design

Fill in the blank: An organisation will often begin by testing ________, pulling samples from along the manufacturing line and testing the finished product.

• raw materials

• packaging labels

• employee schedules

• shipping routes

Why is testing at various stages of the manufacturing process important?

• To increase marketing reach

• To identify where a production problem is occurring and the remedial steps required to prevent it happening in the future

• To reduce the number of employees

• To improve packaging design

The purpose of measuring manufactured parts in the context of Quality Control (QC) is to:

• ensure the parts meet specified standards and tolerances

• increase the speed of production

• reduce the cost of raw materials

• improve the appearance of the parts
