Extensive Tests in All Product Phases

The Design Verification Plan and Report is a summary of important information regarding quality management. It informs about the quality of different processes up to the final products. The DVP&R is complex and, depending on the industry, even mandatory.

Information on and Guidelines for the Design Verification Plan and Report

Design verification is one of the most important elements in all product developments. It contributes significantly to ensuring that the finished product is identical to the developed product. If it is not done, it is possible to produce products that are completely different from the prototypes or the designed products. As soon as the preparations are completed, the development of suitable verification procedures follows. It is also recommended to develop procedures for simple verification activities. This ensures higher accuracy and quality in the final result. In addition, multiple tests can also be carried out in the same way. To what extent a procedure is developed / executed depends on the degree of difficulty of the activities. Small to very large documents are possible. Therefore, the formats must be adapted in each case. Only the relevant points for verification measures should be included.

The verification time can be significantly reduced if all more or less similar tests are performed directly one after the other. In addition, shorter activities can be planned if longer tests are performed that do not require stringent monitoring. The order in which all activities are carried out must also be considered. If tests are destructive, it is advisable to execute the chronology between minimum and maximum destructive. In this way, the number of necessary tests can be limited. It can be advantageous to commit to verification activities, because then the test results are available for all further tests.

There are different guidelines for different industries when it comes to the Design Verification Plan and Report. They are related to the FMEA analysis. This so-called Failure Mode and Effects Analysis is used to investigate problems that can occur in the course of system malfunctions. This is often the first step in a system reliability study. In this course, the largest possible number of subsystems, assemblies and elements is tested. From this, the causes and consequences of errors can be identified. For all elements, these causes and consequences can be stored in an FMEA worksheet in relation to the rest of the system. The minimum requirements for DVP&R can be found in EN ISO 9001.

Applications for DVP and R

While the cost of using DVP&R may seem high at first, it can become much more expensive if a company does not use the Design Verification Plan and Report. Among other things, this can damage a company's reputation if the final product does not meet the expectations that were placed on it. There are many steps in the design process where testing should take place, from conceptual design to the finished product. The methods and types of testing may differ, but the guidelines apply to all.

Especially in the automotive industry, processes relating to the Design Verification Plan and Report have been used time and again. Meanwhile, however, DVP&R is used in almost all other manufacturing areas, including the chemical, electrical, mechanical and pharmaceutical industries. This is due to the fact that DVP and R can significantly reduce failure modes, but significantly increase product reliability.

For example, Design Verification Plan and Report or DVP&R software is used in production, detailed design and pre-production, specification development, or concept development through to design detailing. Additional tools that can be used together with the DVP&R software are configuration and requirements management.

The use of DVP&R or a DVP&R Software

The Design Verification Plan and Report can be used to correct defects. In addition, DVP&R allows you to perform repeat tests before obligations for production readiness and stock keeping arise. Proof testing is also part of DVP and R when prototypes are involved. Rather than testing for specifications, tests are developed to check for possible product failure. In this way, products are tested for their purpose to enable performance to be improved beyond that. Through these tests, possible faults can be detected. This information is helpful in that it can reveal warranty issues and the resulting costs.

Acceptance testing can be seen as a kind of non-destructive test used in the production units. Depending on the failure frequency, the product units and the inspection costs, tests can be carried out on the first products or adapted random samples can be taken. It is also possible to test all units.

Thus, different methods can be used in the DVP and R. Some methods in Design Verification Plan and Report can be performed quickly and inexpensively. These include inspection, for example. Others, however, are complex and cost-intensive. Among these DVP&R measures are functional tests. A characteristic of the Design Verification Plan and Report is that the analysis is often used in the development of products. It can be used to substantiate arguments relating to a long life cycle.

Advantages of the DVP&R application

Many companies know how important it is to test and verify their products and put them in the same place as the original design. Members and managers of design and quality departments therefore need to know how design verification should be performed and how the Design Verification Plan and Report should be created. High-quality software is a good way for employees to acquire the necessary knowledge. In this way they develop the important skills to be able to initiate DVP&R for new products.

With a DVP&R software different areas can be handled. This includes the creation of concepts in detail, their development and specialization, but also the planning of the execution with pre-productions and the final production.

In the Design Verification Plan and Report all important information is listed, which is important on the basis of the quality management. It also provides information about the quality of the processes and the resulting end products. This is a complex process that, depending on the industry, may become mandatory. A DVP&R software has a supporting effect.

Using a clever software in this area, supports the product development process significantly and receives all important information regarding the DVP&R.
