Quality Control Processes: PPAP vs. PSW vs. ISIR

Quality Control Processes

Quality Control processes play a critical role in production today. There are several different types of Quality Control in the production process. In this blog post, we are going to take a look at three of the main ones.

Why are Quality Control Processes Important?

Quality Control (QC) is critical for any business, as it ensures that your company delivers a product that meets or exceeds customer expectations. It forms the basis of an efficient company that reduces waste and operates at high productivity levels.

What Quality Control Processes are There and What Do They Do?

There are many different Quality Control processes, which we will discuss in more detail below. However, it is important that you use a procedure or a set of procedures to implement QC at your business.

You must define a set of quality criteria to measure your product against. So, what are some of the different ways that you can go about doing this?

PPAP Quality Control

The first type of Quality Control we are going to take a look at is PPAP, which stands for Production Part Approval Process. This is an effective tool in terms of establishing confidence in suppliers of components and their production processes.

It defines the approval process for revised or new parts and parts that have been created using significantly revised or new production methods.

The process of PPAP consists of 18 elements that may be needed for production-level parts to be approved. PPAP is a beneficial approach when it comes to verifying that the supplier understands all of the requirements and specifications in terms of customer engineering design. 

PSW Quality Control

Next, we have PSW Quality Control, which relates to the former because it is the cover sheet for PPAP. PSW stands for Part Submission Warrant. It is essentially used, to sum up, the entire PPAP package, providing critical data about the approval.

According to the PPAP manual from AIAG, which is widely used today, it is the 18th (and final) point of PPAP. Some of the information that will be collected on the form includes the declaration of the production rate, reason for submission, weight of the part, date of the submission, drawing number, and more.

ISIR Quality Control

Finally, IRIS stands for Initial Sample Inspection Report, and this is a critical element of the sampling process. It is important because it documents the test results at the initial sample stage. Before a product goes into series production, it needs to be created via a series production process under realistic conditions and then submitted to the consumer for review. This initial batch of products is called the initial sample. The ISIR can then be used by the supplier to provide evidence that the products delivered meet the customer quality requirements. 

To conclude, Quality Control is critical for all businesses involved in construction today. You need to give considerable thought to the process of Quality Control to ensure that it is implemented effectively.
