Product Lifecycle Management (PLM) is the art of managing the entire lifecycle of a product from its conception to disposal.
PLM software give companies a view on every aspect of their product development process. The definition is clear, but is the sense clear as well? The fact is, there is no PLM-software uniquely identifiable as such.
PLM is about the integration of different software: CAD to draw a product, CAE to test it, CAM to make it, PDM to manage product data and DM to plan the production.
