State the product design specification considering output shaft design factor
The product design specification (PDS) is the essential definition of what the product is required to provide.
The PDS is a statement of what the customer wants the product to achieve. In some cases the customer is external and in some cases (e.g. product range extensions for own-brand products) the customer is internal. In every case, a PDS must be prepared to act as a reference for the objectives of the design.
This is initially a statement by the customer of the design intent but it should be expanded by the design and development function to give all the technical detail and limits that are realistically achievable.
