Obsolescence can damage all three parts of the triple bottom line (TBL): people, planet and profit. Although it may increase short-term sales, frequent product replacement can create social costs, environmental damage and long-term economic risks.
The Reasoning
Obsolescence occurs when a product becomes unusable, unsupported or undesirable. It may result from technological change, changing fashions, material failure or planned obsolescence, where a product is deliberately designed with a limited useful life.
Its effects must be considered across the complete TBL:
| TBL dimension | Effects of obsolescence |
|---|---|
| People (social) | Consumers may face repeated replacement costs, loss of access to repairs and frustration when compatible parts or software support are withdrawn. However, replacement products may offer improved safety, accessibility or performance. |
| Planet (environmental) | Shorter product lifespans increase raw-material extraction, manufacturing, transport, energy use and waste. Electronic products can create hazardous e-waste, particularly when components cannot be separated or recycled. |
| Profit (economic) | Manufacturers may gain short-term revenue from repeat purchases. However, poor durability can damage brand reputation, reduce customer loyalty and create costs associated with warranties, regulation, take-back schemes or scarce materials. Repairable and upgradeable products can instead generate service-based revenue. |
A responsible designer should apply life cycle thinking, considering impacts from raw-material extraction to disposal. Strategies such as modular construction, standardized components, software support, repair services and design for disassembly can extend product life and reduce negative TBL impacts.
A common misconception is that obsolescence always benefits profit. It may raise sales temporarily, but the economic dimension includes long-term business resilience, not merely immediate revenue.
Exam Technique
For an IB Design Technology response, identify the type or cause of obsolescence, then explain one linked consequence for each TBL dimension. For an evaluate question, balance short-term commercial benefits against long-term social, environmental and economic costs, finishing with a justified judgment about the designer's responsibility.
