First Samples, or OTS (Off Tool Sample) must be evaluated comprehensively, and separate check sheets/reporting formats must be used to evaluate different attributes for the product. Each and every quality has its own specific standards showing the tool used for examination and the other testing conditions as well.

The assessment items, in general, should include the following attributes, although it relies on the nature of the product to choose what attributes should be tested or not, for instance, plastic or resin based parts cannot be tested for welding performance. So, it's important to choose appropriate assessment items for supply products.

1. Appearance: For exterior body parts particularly; paint, colour, rust or decomposition and texture checking etc.

2. Dimensions: Distances, Pitches, and measurements such as diameters, radii, surface profiles, Angles. Clearances and Level ness etc.

3. Material: Basic material characteristics, tensile strength, flexural strength, yield strength, exterior treatment tests, chemical and physical properties etc.

4. Performance: strength tests and practical analysis of functional parts like engine, switches, air-conditioners, steering assemblage and exhaust assembly etc.

5. Fitment: (for Assembly products) Fitment with the mating components, fitment scrutiny on assembly lines to check whether it's easy for an operative to install part under the model work instructions. Fitment on checking fixtures as well must be evaluated.

6. Workability: Workability investigation of the product. Operational performance after fitment.

7. Checking Fixture Evaluation: Checking fixtures and measurements also need to be evaluated and assessed against specific standards.

8. Product Nomenclature: As discussed above, a car comprises of hundreds of components, look similar to each other, but are quite different. So it's vital to make sure that the component identification is feasible for the fast paced manufacturing. Product accessories such as nuts, bolts and wires etc. should also be checked against the specifications.

It is significant to first establish a grade system of the parts assigned to suppliers, and in fact for all products. This ranking must be based on the nature of their function, nature of manufacturing procedure, cost of production and criticality of their performance. Product assessment, and in some cases, Supplier Selection criterion should be established on the grounds of these ranking and obviously , the quality assurance standards should be more stringent for the high ranking products and could be a bit lenient for the lower grading non functional products (Hahn et al, 1990, 2-7).

The assessment items described above, should be put up under practice in a sequential manner, step by step assessment, this means if some product fails to satisfy the dimensional and material assessment standards then it shouldn't be evaluated for Perf本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
