Discuss APICS CPIM-Part-2 Exam Topic 1 Question 15

Which of the following observations in a manufacturing plant best illustrates the poka-yoke technique of process design?

AThe number of types of fasteners is reduced from 25 to 5.

BCustomized containers hold mixed sets of parts.

CAn andon is installed.

DA part attribute defines correct orientation.

Suggested Answer: D

The poka-yoke technique of process design is a method for preventing or detecting errors and defects in the manufacturing process.Poka-yoke means ''mistake-proofing'' in Japanese, and it aims to eliminate human errors by creating systems that either make it impossible for a mistake to occur or make the mistake immediately obvious once it has occurred1.One way to implement poka-yoke is to use part attributes, which are physical features of a part that ensure it can only be assembled or used in the correct way2. For example, a part attribute can define the correct orientation of a part, such as a notch, a hole, a shape, or a color, so that it can only fit into the matching component. This prevents the operator from inserting the part incorrectly or using the wrong part.

The other options do not illustrate the poka-yoke technique of process design.Reducing the number of types of fasteners is an example of standardization, which is a method for simplifying and streamlining the production process by minimizing variation and complexity3.Customized containers that hold mixed sets of parts are an example of kitting, which is a method for organizing and delivering parts or materials to the point of use or consumption in the production process4.An andon is a visual or audible signal that indicates the status of a machine or process, such as normal, abnormal, or emergency5. An andon can be used to alert operators or supervisors of problems or issues, but it does not prevent or detect errors by itself.

Customized containers can lead to confusion, not clarity!

Wait, how does a part attribute help prevent mistakes?

An andon is cool, but not really poka-yoke.

I think the correct orientation part is a better example.

Bernadine 11 months ago

Reducing fasteners sounds efficient!

I’m confused because B talks about customized containers, which could help, but I don’t know if that’s really poka-yoke. I’m leaning towards D too.

Filiberto 12 months ago

I feel like I’ve seen a question like this before, and it was about making things easier to assemble. D seems to fit that idea best.

Amina 12 months ago

I'm not entirely sure, but I remember something about poka-yoke being about error-proofing. Maybe A is relevant since reducing fasteners could simplify the process?

I think the answer might be D because it mentions correct orientation, which sounds like a way to prevent errors.

I'm a little confused by the choices here. They all seem to describe some kind of manufacturing improvement, but I'm not sure which one specifically relates to poka-yoke. I'll need to think carefully about the definition of poka-yoke and how it differs from other process improvement methods.

Option D looks promising to me. Designing a part attribute that defines the correct orientation seems like a classic poka-yoke technique, as it would prevent the part from being installed incorrectly. I'll focus on understanding that option in more detail.

Hmm, I'm a bit unsure about this one. The poka-yoke concept is new to me, and I'm not entirely sure how to recognize it in the given observations. I'll need to review my notes and try to understand the core principles of poka-yoke before attempting to answer.

Filiberto 1 year ago

This question seems straightforward. I think the key is to identify the poka-yoke technique, which is a process design approach to prevent errors. The options describe different manufacturing observations, so I'll need to analyze each one to determine which one best illustrates poka-yoke.

Okay, I think I've got a handle on this. Creating a template sounds like it could be a useful way to streamline the process of importing and transforming data in the future.

Creating a cluster policy could be a good way to optimize the cluster settings, but I'll need to research that more.

I'm pretty confident that the face recognition at 70 meters is the spec that would need to change. That's an extremely long distance for accurate facial recognition.

Exactly, option D directly ties to mistake-proofing in the design itself, not just reacting to errors.

Verda 2 years ago

Andon is more about immediate response to issues. Poka-yoke should prevent errors from occurring at all.

Nelida 2 years ago

True, but what about option C? Installing an andon also prevents errors by alerting operators.

Jean 2 years ago

Option D makes sense. If a part attribute defines the correct orientation, it minimizes errors.

Bernardine 2 years ago

Yeah, poka-yoke is all about preventing mistakes. I'm leaning towards option D.

Brinda 2 years ago

I think the question is quite interesting. It's about error-proofing in manufacturing, right?
