Design verification ensures that the SHOE as designed is the same as the SHOE as intended. Unfortunately, many design projects do not complete thorough design qualification resulting in products that do not meet customer expectations and require costly design modifications.

Project activities in which design verification is useful:
? Detailed Design concept of SHOE
? Specification Development
? Detailed Design through to Pre-Production
? Production of SHOE
Other tools that are useful in conjunction of SHOE with design verification:
? Requirements Management
? Configuration Management
Some important test that we have conducted for design verification of SHOE are listed below-
Development Test- Basically this test is regarding the raw materials such as lace, leather and sole of the shoe as in its quality and design. This test will not be helpful in final testing. However, this will aid the further process of shoe making.

Prototype Testing- This type of testing is done at many different levels, probably at all levels when required. It compares the produced shoe with the pre-designed samples. It is necessary to check the shoe at each stage because it will show at what point the deficiency is occurring or at what stage does the product need to be improved. Checking at every stage is necessary to get the process aligned. Also checking per unit is required because every unit of shoe is count on its quality. So, in this test both at each stage and each unit checking is required. It is closely related to the final expected output.

Proof testing- Proof testing also gets the product final ready but the only difference here is that in proof testing, the product is checked after it is produced. That means shoe is first made and then checked. It is more of a quality control check where the product is tested for the purpose of its guaranty or warranty. In shoe making company, the proof testing is done for the sole or for the fabric used such as leather, the lace used but in terms of its toughness and flexibility.

Acceptance testing- This testing is done randomly after the quality check to ensure that all the products are met with its expectations and that they also meet the warranty criteria. It is done after the final production and before putting it in the market. This testing is done in samples from random boxes of shoes to ensure that the shoes are not only made but also checked properly.
??Demonstration- Demonstrations can be conducted in actual or simulated environments. This is the simplest method as the shoe can be demonstrated with one hand. So, the test is relatively inexpensive.

??Inspection- Physical characteristics of the SHOE can be easily verified with this Inspection test. SHOE with a certain colour, a certain height or labelled in a specific manner, inspection would be used to confirm that the requirements have been met. Inspection is typically one of the less expensive verification methods.

??Analysis- With this test lifecycle of the SHOE can be determined. It is often used in the design of product. It can also be used to verify the design and is often the preferred method if
testing is not feasible or the cost of testing is prohibitive, and risk is minimal.

??Similarity- Materials or features that are similar to those of another product that has met or exceeded current specifications, an analysis to illustrate this similarity may be used to verify a requirement. If SHOE material is to be water resistant and is found true in other applications have been chosen, an analysis of similarity could be used.

??Testing- Most expensive of all the method is the testing method. depending on complexity as well as equipment and facility requirements. However, sometimes it is the only acceptable means for verifying aspects of a design.

Of the above-mentioned methods of verification and test, the method that should be adopted is the method that best suits the company in budget but considering the position of the product.

Some methods may be easy and quick and comparatively less expensive but these types of methods are best suited when the product line of the company is sound and secure.

There may be case where adoption of one or more methods is necessary in order to achieve success.

There may be a case where the combination of two or more verification test methods is required.

Combination or use of more than one method is required when the process of manufacturing is not aligned or the process is faulty.

In a shoe making company, at initials the development testing would work. In this type of company, design and outlook of the product is most important. So, this test should be done carefully. It will assist the final production design.

Prototype testing is crucial but it is not required to do frequently in a shoe making company as the production design for the shoe will not be as complex. It is okay to do it once in a while but frequently testing prototype is not suggested.

Shoe making company must conduct the proof testing regularly. It is the most important part for them as it will show whether the product will be accepted in the final market or not or are there any suggestions necessary to be implemented.

If the company is conducting proof testing properly and the production line is in line with the pre-designed sample than acceptance testing can be conducted as and when necessary and not regularly.

Of all verification methods, demonstration is considered good to be implemented as it does not require any specialised qualification. It is good to use this method when there is a party related concern of quality.

Inspection is implemented when there are any uncertainties regarding the outer look of the product.

However, most appropriate method of verifying would be analysis. Even if it’s costly and requires a lot more time than the other methods, this method provided detailed information about the shoe that of it has met the quality criteria and the production in whole has met the pre-determined protocols.

Similarity will not work in a shoe production verification method as this is completely based on the quality of the product and even though the final production has gone through similar process it is not necessary that it will have same impact. So, this is not useful.

When there is fulfilment of a larger order, only then it is reasonable to go through testing method, otherwise on process different methods will do the work. It is such because, it is expensive and time consuming. So, unless necessary, it is not advisory to go for this method.
