Definition
The Process of Becoming Outdated
Obsolescence describes the process by which something becomes antiquated, out of date, old-fashioned, no longer in general use, no longer useful, or superseded by innovation. In a biological context, it refers to a state of being imperfect or rudimentary compared to corresponding parts in other organisms.[1][2]
Formal Standard Definition
The international standard IEC 62402:2019, titled "Obsolescence Management," defines obsolescence as "the transition from available to unavailable from the manufacturer in accordance with the original specification."[3]
The Role of Replacement
Obsolescence frequently occurs when a replacement emerges that offers superior advantages over the disadvantages associated with maintaining or repairing the original item. The term "obsolete" also denotes something already disused, discarded, or antiquated, typically following a gradual decline in popularity.[4]
Consequences and Impacts
Accelerated Technological Change
Rapid advancements in technology lead to the swift development and market introduction of new components. This dramatically alters production methods and the availability of components. Consequently, product life cycles often become misaligned with the life cycles of essential components, a phenomenon known as obsolescenceโthe status of a part when it is no longer offered by its original manufacturer.[5]
Industry-Wide Challenges
This issue is particularly pronounced in the electronics sector, where the procurement timelines for microelectronic parts are frequently shorter than the manufacturing and support durations for the products utilizing them. However, obsolescence extends beyond electronics to encompass materials, textiles, mechanical parts, software, specifications, standards, processes, and even human skills. Proactive obsolescence management is crucial to mitigate significant costs.[5]
Beyond Electronics
While electronics are highly susceptible, obsolescence affects numerous domains. For instance, the transition from vacuum tubes to transistors in consumer electronics, though largely complete, saw tubes persist in high-power transmitters due to transistor limitations at the time. Furthermore, the discontinuation of manufacturing technologies or the business failure of component suppliers can render even simple integrated circuits obsolete, often making redevelopment economically unviable due to superseded functionality and cost-effectiveness.[4] Changes in complementary products can also render items functionally obsolete, such as the advent of automobiles making buggy whips obsolete.[4]
Types of Obsolescence
Technical Obsolescence
This occurs when a new product or technology supersedes an older one, making the new option preferable. Historical examples include bronze replacing flint for tools, DVDs replacing videocassettes, and telephones replacing telegraphs. Rapid advancements, such as in central processing units (CPUs), frequently render older models obsolete. The swift obsolescence of data formats and supporting infrastructure can also lead to critical information loss, a phenomenon known as digital obsolescence.[4]
Functional Obsolescence
Items become functionally obsolete when they can no longer adequately perform their intended purpose. For example, while an Avro Lancaster bomber could theoretically be adapted for modern munitions, its vulnerability to contemporary air defenses would render it essentially useless in most scenarios. Manufacturers and repair services often cease support for obsolete products due to declining user bases and profitability, leading to scarcity of parts and increased maintenance costs, ultimately making continued operation prohibitively expensive.[4]
Architectural Obsolescence
First applied to the built environment around 1910, this refers to the loss of value in buildings due to factors like changing functions, tastes, or competition from newer structures. For instance, hotels might experience obsolescence faster than banks due to their more dynamic functional requirements and evolving aesthetic preferences. Estimates of average architectural lifespans attempt to quantify this impending obsolescence.[6][7]
Planned Obsolescence
Marketers may deliberately incorporate obsolescence into product strategies to stimulate long-term sales. This involves designing products with a predetermined lifespan, encouraging consumers to replace them within a specific timeframe, such as an appliance designed to fail within five years.[4]
Inventory Obsolescence
This occurs when retailers or vendors hold stock that fails to sell as anticipated, leading to products becoming obsolete on their shelves. Excessive inventory levels or overestimation of demand can negatively impact an organization's cash flow. Regular stock assessments are vital to identify slow-moving or unsellable items.[8]
Style Obsolescence
A product becomes obsolete in terms of style when it is no longer desirable due to shifting fashion trends, even if it remains functional. Flared leg jeans, for example, may become stylistically obsolete as fashion trends move towards different cuts. However, style obsolescence can be cyclical, with previously obsolete styles potentially regaining popularity over time, as seen with "acid-wash" jeans.[4]
Obsolescence Management
Mitigating Obsolescence Effects
Obsolescence management, also known as "Diminishing Manufacturing Sources and Material Shortages" (DMSMS), involves activities undertaken to counteract the effects of obsolescence. Key strategies include conducting last-time buys (LTBs) and lifetime buys (LTBs), where large quantities of components are purchased to cover the expected product life. Continuous obsolescence monitoring is also essential to anticipate and address potential issues proactively.[5]
