Obsolescence

Last updated

Obsolescence is the process of becoming antiquated, out of date, old-fashioned, no longer in general use, or no longer useful, or the condition of being in such a state. When used in a biological sense, it means imperfect or rudimentary when compared with the corresponding part of other organisms. [1] [2] The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification". [3]

Contents

Obsolescence frequently occurs because a replacement has become available that has, in sum, more advantages compared to the disadvantages incurred by maintaining or repairing the original. Obsolete also refers to something that is already disused or discarded, or antiquated. [4] Typically, obsolescence is preceded by a gradual decline in popularity.

Consequences

Driven by rapid technological changes, new components are developed and launched on the market with increasing speed. The result is a dramatic change in production methods of all components and their market availability. A growing industry sector is facing issues where life cycles of products no longer fit together with life cycles of required components. This issue is known as obsolescence, the status given to a part when it is no longer available from its original manufacturer. The problem of obsolescence is most prevalent for electronics technology, wherein the procurement lifetimes for microelectronic parts are often significantly shorter than the manufacturing and support life cycles for the products that use the parts. However, obsolescence extends beyond electronic components to other items, such as materials, textiles, and mechanical parts. In addition, obsolescence has been shown to appear for software, specifications, standards, processes, and soft resources, such as human skills. It is highly important to implement and operate an active management of obsolescence to mitigate and avoid extreme costs. [5]

Types

Technical obsolescence

Technical obsolescence usually occurs when a new product or technology supersedes the old one, and it is preferred to use the new technology instead. Historical examples of new technologies superseding old ones include bronze replacing flint in hand-tools, DVDs replacing videocassettes, and the telephone replacing the telegraph. On a smaller scale, a particular product may become obsolete when a newer version replaces it. Many products in the computer industry become obsolete in this manner. For example, central processing units (CPUs) frequently become obsolete in favor of newer, faster units. Singularly, rapid obsolescence of data formats along with their supporting hardware and software can lead to loss of critical information, a process known as digital obsolescence.

In many cases, a new technology does not totally replace the old technology because the old technology is still useful in certain applications. For example, transistors replaced vacuum tubes in TV and radio receivers in the 1960s, but vacuum tubes were still used for powerful transmitters because transistors for these power levels were not available. Even today, one has to use multiple transistors for a purpose that used to require just one tube. [ citation needed ]

Products may also become obsolete when supporting technologies are no longer available to produce or even repair a product. For example, many integrated circuits, including CPUs, memory and even some relatively simple logic chips may no longer be produced because the technology has been superseded, their original developer has gone out of business or a competitor has bought them out and effectively killed off their products to remove competition. It is rarely worth redeveloping a product to get around these issues since its overall functionality and price/performance ratio has usually been superseded by that time as well.

Some products become technologically obsolete due to changes in complementary products which results in the function of the first product being made unnecessary. For example, buggy whips became obsolete when people started to travel in cars rather than in horse-drawn buggies.

Functional obsolescence

Items become functionally obsolete when they can no longer adequately perform the function for which they were created. For example, while one could theoretically adapt an Avro Lancaster to deploy modern JDAM bombs, the situations in which it could actually succeed at doing so against modern air defenses would be so few that it would be essentially useless.

Manufacturers and repair companies will typically cease support for products once they become obsolete as keeping production lines in place and parts in storage for a shrinking user base becomes unprofitable. This causes scarcity of spare parts and skilled technicians for repairs and thus escalates maintenance costs for obsolete products. This ultimately leads to prohibitive expense in keeping old technology functioning.

Architectural obsolescence

The term "obsolescence" was first applied to the built environment in 1910 in an attempt to explain American skyscrapers' sudden loss of value. [6] New York engineer Reginald P. Bolton attributed this phenomenon to "something new and better out-competing the old" and calculated the average architectural lifespan of varying building types in order to formulate a rough estimate for their impending obsolescence. [6] For example, he suggested that hotels' obsolescence will occur faster than banks due to their ever-changing functions and tastes. [7]

Planned obsolescence

Sometimes marketers deliberately introduce obsolescence into their product strategy, with the objective of generating long-term sales volume by reducing the time between repeat purchases. One example might be producing an appliance which is deliberately designed to wear out within five years of its purchase, pushing consumers to replace it within five years.

Inventory obsolescence

Inventory obsolescence occurs when retailers and other vendors hold stocks for anticipated future sales which turn out to be too slow to materialise. Holding excessive levels of stock or over-predicting potential demand increase the risks of products becoming obsolete and have a detrimental effect on the organisation's cash flow. Companies may address this problem alongside a periodic stock count by assessing which of their stock items are slow-moving or not selling at all. [8]

Style obsolescence

When a product is no longer desirable because it has gone out of the popular fashion, its style is obsolete. One example is flared leg jeans; although this article of clothing may still be perfectly functional, it is no longer desirable because style trends have moved away from the flared leg cut.

Because of the "fashion cycle", stylistically obsolete products may eventually regain popularity and cease to be obsolete. An example is "acid-wash" jeans, which were popular in the 1980s, became stylistically obsolete in the mid to late 1990s, and returned to popularity in the 2000s.

Obsolescence management

Obsolescence management, also referred to as "Diminishing Manufacturing Sources and Material Shortages" (DMSMS), is defined as to the activities that are undertaken to mitigate the effects of obsolescence. Activities can include last-time buys, lifetime buys, and obsolescence monitoring.

Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function and the amplifying function, as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).

In several fields, especially computing, deprecation is the discouragement of use of some terminology, feature, design, or practice, typically because it has been superseded or is no longer considered efficient or safe, without completely removing it or prohibiting its use. Typically, deprecated materials are not completely removed to ensure legacy compatibility or back up practice in case new methods are not functional in an odd scenario.

<span class="mw-page-title-main">Design life</span> Time the creator plans a product to last

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. It is not always the actual length of time between placement into service of a single item and that item's onset of wearout.

In economics and industrial design, planned obsolescence is a policy of planning or designing a product with an artificially limited useful life or a purposely frail design, so that it becomes obsolete after a certain pre-determined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as unfashionable. The rationale behind this strategy is to generate long-term sales volume by reducing the time between repeat purchases. It is the deliberate shortening of the lifespan of a product to force people to purchase functional replacements.

<span class="mw-page-title-main">Interchangeable parts</span> Components that are identical for practical purposes

Interchangeable parts are parts that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as filing. This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair.

<span class="mw-page-title-main">Digital obsolescence</span> Data loss as the format goes into disuse

Digital obsolescence is the risk of data loss because of inabilities to access digital assets, due to the hardware or software required for information retrieval being repeatedly replaced by newer devices and systems, resulting in increasingly incompatible formats. While the threat of an eventual "digital dark age" was initially met with little concern until the 1990s, modern digital preservation efforts in the information and archival fields have implemented protocols and strategies such as data migration and technical audits, while the salvage and emulation of antiquated hardware and software address digital obsolescence to limit the potential damage to long-term information access.

<span class="mw-page-title-main">DIY audio</span>

DIY Audio, do it yourself audio. Rather than buying a piece of possibly expensive audio equipment, such as a high-end audio amplifier or speaker, the person practicing DIY Audio will make it themselves. Alternatively, a DIYer may take an existing manufactured item of vintage era and update or modify it. The benefits of doing so include the satisfaction of creating something enjoyable, the possibility that the equipment made or updated is of higher quality than commercially available products and the pleasure of creating a custom-made device for which no exact equivalent is marketed. Other motivations for DIY audio can include getting audio components at a lower cost, the entertainment of using the item, and being able to ensure quality of workmanship.

<span class="mw-page-title-main">Electronic waste recycling</span> Form of recycling

Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used. Like other waste streams, reuse, donation, and repair are common sustainable ways to dispose of IT waste.

Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time.

<span class="mw-page-title-main">Future-proof</span> Planning and building for time to come

Future-proofing is the process of anticipating the future and developing methods of minimizing the effects of shocks and stresses of future events. Future-proofing is used in industries such as electronics, medical industry, industrial design, and more recently, in design for climate change. The principles of future-proofing are extracted from other industries and codified as a system for approaching an intervention in an historic building.

Remanufacturing is "the rebuilding of a product to specifications of the original manufactured product using a combination of reused, repaired and new parts". It requires the repair or replacement of worn out or obsolete components and modules. Parts subject to degradation affecting the performance or the expected life of the whole are replaced. Remanufacturing is a form of a product recovery process that differs from other recovery processes in its completeness: a remanufactured machine should match the same customer expectation as new machines.

<span class="mw-page-title-main">Retrofitting</span> Addition of new technology or features to older systems

Retrofitting is the addition of new technology or features to older systems. Retrofits can happen for a number of reasons, for example with big capital expenditures like naval vessels, military equipment or manufacturing plants, businesses or governments may retrofit in order to reduce the need to replace a system entirely. Other retrofits may be due to changing codes or requirements, such as seismic retrofit which are designed strengthening older buildings in order to make them earthquake resistant.

A computer liquidator buys computer technology and related equipment that is no longer required by one company, and resells ("flips") it to another company. Computer liquidators are agents that act in the computer recycling, or electronic recycling, business.

Diminishing manufacturing sources and material shortages (DMSMS) or diminishing manufacturing sources (DMS) is defined as: "The loss or impending loss of manufacturers of items or suppliers of items or raw materials." DMSMS and obsolescence are terms that are often used interchangeably. However, obsolescence refers to a lack of availability due to statutory or process changes and new designs, whereas DMSMS is a lack of sources or materials.

<span class="mw-page-title-main">Computer hardware</span> Physical components of a computer

Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

A spare part, spare, service part, repair part, or replacement part, is an interchangeable part that is kept in an inventory and used for the repair or refurbishment of defective equipment/units. Spare parts are an important feature of logistics engineering and supply chain management, often comprising dedicated spare parts management systems.

Cannibalization of machine parts, in the maintenance of mechanical or electronic systems with interchangeable parts, refers to the practice of removing parts or subsystems necessary for repair from another similar device, rather than from inventory, usually when resources become limited. The source system is usually crippled as a result, perhaps only temporarily, in order to allow the recipient device to function properly again.
