Circular economy
A circular economy (also referred to as circularity or CE) is a model of resource production and consumption in any economy that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products for as long as possible.
See Product lifetime and Circular economy
Computer-assisted web interviewing
Computer-assisted web interviewing (CAWI) is an Internet surveying technique in which the interviewee follows a script provided in a website.
See Product lifetime and Computer-assisted web interviewing
Design life
The design life of a component or product is the period of time during which the item is expected by its designers to work within its specified parameters; in other words, the life expectancy of the item. Product lifetime and design life are product design and Sustainable design.
See Product lifetime and Design life
Distribution (mathematics)
Distributions, also known as Schwartz distributions or generalized functions, are objects that generalize the classical notion of functions in mathematical analysis.
See Product lifetime and Distribution (mathematics)
Durability
Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime.
See Product lifetime and Durability
Durable good
In economics, a durable good or a hard good or consumer durable is a good that does not quickly wear out or, more specifically, one that yields utility over time rather than being completely consumed in one use.
See Product lifetime and Durable good
Embedded emissions
One way of attributing greenhouse gas (GHG) emissions is to measure the embedded emissions of goods that are being consumed (also referred to as "embodied emissions", "embodied carbon emissions", or "embodied carbon").
See Product lifetime and Embedded emissions
Embodied energy
Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy were incorporated or 'embodied' in the product itself.
See Product lifetime and Embodied energy
Focus group
A focus group is a group interview involving a small number (sometimes up to ten) of demographically predefined participants.
See Product lifetime and Focus group
Interview
An interview is a structured conversation where one participant asks questions, and the other provides answers.
See Product lifetime and Interview
Life cycle thinking
Life cycle thinking is an approach that emphasizes the assessment and minimization of environmental impacts at all stages of a product's life. Product lifetime and life cycle thinking are Sustainable design.
See Product lifetime and Life cycle thinking
Likert scale
A Likert scale is a psychometric scale named after its inventor, American social psychologist Rensis Likert, which is commonly used in research questionnaires.
See Product lifetime and Likert scale
Maintainability
Maintainability is the ease of maintaining or providing maintenance for a functioning product or service.
See Product lifetime and Maintainability
Memory
Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed.
See Product lifetime and Memory
Planned obsolescence
In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is the concept of policies planning or designing a product with an artificially limited useful life or a purposely frail design, so that it becomes obsolete after a certain predetermined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as unfashionable.
See Product lifetime and Planned obsolescence
Probability
Probability is the branch of mathematics concerning events and numerical descriptions of how likely they are to occur.
See Product lifetime and Probability
Product design
Product design is the process of creating new products for sale businesses to its customers.
See Product lifetime and Product design
Product stewardship
Product stewardship is an approach to managing the environmental impacts of different products and materials and at different stages in their production, use and disposal.
See Product lifetime and Product stewardship
Repairability
Repairability is a measure of the degree to and ease with which a product can be repaired and maintained, usually by end consumers.
See Product lifetime and Repairability
Service life
A product's service life is its period of use in service.
See Product lifetime and Service life
Statistics
Statistics (from German: Statistik, "description of a state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
See Product lifetime and Statistics
Sustainable development
Sustainable development is an approach to growth and human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. Product lifetime and Sustainable development are Sustainable design.
See Product lifetime and Sustainable development
Sustainable products
Sustainable products are products who are either sustainability sourced, manufactured or processed that provide environmental, social and economic benefits while protecting public health and environment over their whole life cycle, from the extraction of raw materials until the final disposal. Product lifetime and Sustainable products are Sustainable design.
See Product lifetime and Sustainable products
Throw-away society
The throw-away society is a generalised description of human social concept strongly influenced by consumerism, whereby the society tends to use items once only, from disposable packaging, and consumer products are not designed for reuse or lifetime use.
See Product lifetime and Throw-away society
Waste minimisation
Waste minimisation is a set of processes and practices intended to reduce the amount of waste produced. Product lifetime and waste minimisation are Sustainable development.
See Product lifetime and Waste minimisation
Whole-life cost
Whole-life cost is the total cost of ownership over the life of an asset.
See Product lifetime and Whole-life cost
