1. Identify the functions of the parts of bearings that contribute to the need of VA study.

Case: In order to apply the methodology of value analysis in the case of manufacturing components or sub- assemblies (category that bearings fit within), it is necessary to clarify their place and role for the product they are integrated within, as well as the contribution to its utilization value. In the present case, there is need to find modalities for efficiently applying the method of value analysis to the parts of the products. Such situations appear in the case of the factories manufacturing assembling, bearings, or different sub-assemblies. Applying the value analysis method for studying a sub-assembler simple component has to be done by observing the basic principles, especially the principle of the functional approach. Therefore, it is necessary to go through the following stages:

(a) Accurately identifying the functions of the products that of the sub-assemblies or the simple compo- nents

(b) Determining the product function benefiting from the component or the sub-assembly which has to be analysed

(c) Determining the degree of importance of the product function benefiting from the component or the sub-assembly which has to be analysed

(d) Determining the degree of participation of the component or of the sub-assembly in attaining the level of the function.
