Product Design for Development

The characteristics (features, capabilities, properties) were identified in the context of the requirement development. Technical elements can now be developed through standard parts (screws, nuts, plugs etc.) or mechanical parts, intended for the application. In any case, it is important to secure identified important characteristics 

However, if the tightening torque for the screw is identified as an important characteristic, the choice of tools or the monitoring of the work with the tool may become a safety activity. The production (for example the development of the link through screwing in the screw) needs to be monitored primarily to show that the requirements are developable (often for the first prototypes) and also correctly implemented. Special characteristics are often determined for safety relevant characteristics of the top products. Those are often tested in the serial production for each individual product and the test results are filed in data archives. 

Traditionally we will find four sample phases in the classical development of the automobile industry. The following aims are considered for mechanical parts for these samples  

Generally development processes are also described in phases, which are oriented on historical sample phases. 

The A-sample (concept phase) is often already considered in very early phases of the development and shall be provided along with the offer of the supplier.
