Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".

Life-cycle assessment (LCA or life cycle analysis) is a technique used to assess potential environmental impacts of a product at different stages of its life. This technique takes a "cradle-to-grave" or a "cradle-to-cradle" approach and looks at environmental impacts that occur throughout the lifetime of a product from raw material extraction, manufacturing and processing, distribution, use ...
A generic lifecycle of products. In industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from its inception through the engineering, design, and manufacture, as well as the service and disposal of manufactured products.
For example, if a machine is planned to run 100 hours a week, but in reality runs only 50, then the availability is 50%. [3] Performance – compares the ideal output and the actual output. For example, if a certain process is planned to take 10 minutes, but actually takes 20, then the productivity is 50%. [3]
Combining such data sets can enable accounting for long chains (for example, building an automobile requires energy, but producing energy requires vehicles, and building those vehicles requires energy, etc.), which somewhat alleviates the scoping problem of traditional life-cycle assessments. EIO-LCA analysis traces out the various economic ...
A company's place on the matrix depends on two dimensions – the process structure/process lifecycle and the product structure/product lifecycles. [2] The process structure/process lifecycle is composed of the process choice (job shop, batch, assembly line, and continuous flow) and the process structure (jumbled flow, disconnected line flow, connected line flow and continuous flow).

, "The purpose of the customer life cycle is to define and communicate the stages through which a customer progresses when considering, purchasing and using products, and the associated business processes a company uses to move the customer through the customer life cycle." [2]
