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 ...
The work system life cycle model is iterative and includes both planned and unplanned change. It is fundamentally different from the frequently cited Systems Development Life Cycle (SDLC), which actually describes projects that attempt to produce software or produce changes in a work system. Current versions of the SDLC may contain iterations ...
Examples: ongoing use of outside consultants. In simple terms, this is an archetype whereby a system grows increasingly dependent on an outside intervenor to help it function. In the short-term this works, but in the long term the system is unable to function on its own due to the dependence on the intervention and eventually fails to perform.
It is also "an explicit formal inquiry carried out to help a decision maker identify a better course of action and make a better decision than they might otherwise have made." [2] The terms analysis and synthesis stems from Greek, meaning "to take apart" and "to put together", respectively.
Systems thinking is a way of making sense of the complexity of the world by looking at it in terms of wholes and relationships rather than by splitting it down into its parts.
Life cycle engineering is defined in the CIRP Encyclopedia of Production Engineering as: "the engineering activities which include the application of technological and scientific principles to manufacturing products with the goal of protecting the environment, conserving resources, encouraging economic progress, keeping in mind social concerns, and the need for sustainability, while optimizing ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Systems science, also referred to as systems research or simply systems, [1] is a transdisciplinary [2] field that is concerned with understanding simple and complex systems in nature and society, which leads to the advancements of formal, natural, social, and applied attributions throughout engineering, technology and science, itself.
