Planned obsolescence is the deliberate design of a product so that it becomes unusable, outdated, unfashionable, or difficult to repair after a predetermined period. Its purpose is usually to encourage consumers to replace the product, increasing repeat sales.
Within C1.1 Responsibility of the designer, planned obsolescence raises ethical questions because designers must consider the interests of users, manufacturers, society, and the environment. Decisions about materials, components, software support, repairability, and product styling can all influence a product's useful life.
| Form of planned obsolescence | How it encourages replacement |
|---|---|
| Technical obsolescence | Components are designed with a limited lifespan or cannot be repaired economically. For example, a sealed battery may make an otherwise functional device unusable. |
| Technological obsolescence | New systems, software, or accessories become incompatible with an older product, reducing its functionality. |
| Style obsolescence | Changes in fashion, colour, or form make a functional product appear undesirable or outdated. |
| Systemic obsolescence | A product becomes unusable because related infrastructure, replacement parts, or software support are withdrawn. |
Planned obsolescence can benefit manufacturers through predictable demand and can accelerate the adoption of improved technologies. However, it may increase resource extraction, energy use, electronic waste, and consumer costs. It can therefore conflict with sustainable design, which promotes durability, maintenance, repair, upgrading, reuse, and responsible end-of-life management.
A common misconception is that every product failure proves planned obsolescence. Failure may instead result from poor quality control, misuse, material fatigue, or an unavoidable design compromise. The key distinction is intent: planned obsolescence involves deliberate decisions that shorten or restrict useful product life.
In an IB response, define the term, explain a specific design decision, and evaluate effects on several stakeholders. Avoid giving only an example; connect it explicitly to the designer's ethical and environmental responsibilities.
