QCI LEAN QUESTIONS AND ANSWER

What is the correct sequence of doing Kaizen in a manufacturing plant where Kabir is the team leader?

• Manual then machine then process

• Machine then process

• Manual and then machine

• Process then machine then manual

Answer explanation

The correct sequence in Kaizen starts with 'Manual' to identify issues, followed by 'Machine' to implement solutions, and finally 'Process' to ensure continuous improvement. Thus, 'Manual then machine then process' is the right choice.

One of the main purposes of Taguchi's approach was

• To reduce the impact due to input variation

• Improve quality in production

• Improve product functions

• Better quality control

Answer explanation

Taguchi's approach focuses on reducing the impact of input variation on product quality. By minimizing variability, it enhances overall performance and reliability, making 'To reduce the impact due to input variation' the correct choice.

Siya learned about Taguchi's method in her statistics class, which was a name given to an application of

• Design of experiments

• Process Quality control

• Setting specification limits

• Corrective action method

Answer explanation

Taguchi's method focuses on optimizing processes through the design of experiments, allowing for systematic testing and improvement of quality. Thus, the correct answer is 'Design of experiments'.

In the Quality Engineering approach, Nikita focused on developing

• Stable process

• Robust production technology

• Select better manufacturing technology

• Reduce rejections

Answer explanation

In the Quality Engineering approach, the emphasis is on creating robust production technology to ensure consistent quality and efficiency in manufacturing processes, making it the correct choice.

When the rate of throughput goes up within the existing operating expense at Vanya's bakery, we call this

• Efficiency

• Productivity

• Labour productivity

• Gross margin increase

Answer explanation

When throughput increases without raising operating expenses, it indicates better use of resources, which is defined as productivity. Therefore, the correct answer is 'Productivity'.

Saisha is working on a project and wants to improve her productivity. She believes that productivity is something that

• Takes you faster towards your goal

• Increases your output

• Increases efficiency

• Increases Quality

Answer explanation

Productivity is about achieving goals efficiently. The correct choice, 'Takes you faster towards your goal', emphasizes that productivity accelerates progress, making it a key aspect of effective work.

Rahul believes that productivity measures should drive the increase of

• Throughput

• Output

• Reduces cost

• Batch size

Answer explanation

Throughput measures the rate at which products are produced. Increasing productivity should focus on enhancing throughput to maximize efficiency and output, making it the correct choice.

Aanya is analyzing the productivity of her bakery. She wants to determine the most appropriate formula for productivity. What should she use?

• Throughput/Operating expenses

• Sales/ No of workers

• Sales/Operating expenses

• Inventory turns

Answer explanation

The formula for productivity is best represented by Throughput/Operating expenses, as it measures the efficiency of production relative to costs, highlighting how effectively resources are utilized.

What is one of the key aspects of TPS?

• It is easy to implement

• Requires very little management intervention

• Can be used in any production environment

• It improves production very quickly

Answer explanation

One key aspect of TPS is that it requires very little management intervention, allowing teams to operate more autonomously and efficiently, which is essential for its success in lean production environments.

Why do Ishaan and Kiara practice lean principles in their manufacturing project?

• To increase flow

• To improve efficiency

• To increase quality

• To improve production quantities

Answer explanation

We practice lean principles primarily to increase flow, which enhances the overall efficiency of processes. While improving efficiency, quality, and production quantities are important, the main focus of lean is to streamline flow.
