Product Lifecycle Management (PLM) enables both engineers and non-engineers, across all levels of an organization's value chain to navigate and manage product information at all stages in the product lifecycle. It covers the complete continuum from determining requirements, developing a concept, building a prototype, creating a design, and engineering - to procurement, manufacturing, assembling, packaging, distribution, maintenance, and obsolescence. It allows organizations to maximize their existing investment in assets, resources, and knowledge across that continuum.
