Repairability
Repairability is the degree to which a product can be restored to working condition after a fault or degradation. It reflects design and service factors such as access to components, removable fasteners, diagnostic information, tools, spare-part availability, software support, repair time, cost, safety, and required skill.
In simple terms
In a circular economy, repairability can enable reuse and waste prevention, but a repairable product is not merely one that can theoretically be opened. Practical assessment considers whether failures can be diagnosed, parts can be reached without damage, replacement parts and instructions are available, and repair can be completed safely at a reasonable effort. Scores depend on the method and product category, so results from different schemes may not be directly comparable. Durability and reliability remain separate characteristics.
Why it matters
Repairability can extend product life, delay replacement, and prevent waste while preserving much of the value embedded in manufacturing. It also affects who can maintain a product and at what cost. Clear criteria help designers improve weak points and help purchasers compare products without relying on vague claims that something is repair-friendly.
Example
Two laptops have similar performance, but one uses replaceable batteries, accessible screws, modular storage, published diagnostics, and spare parts available for several years. A defined scoring method can evaluate those features. The score should state its criteria and should not be presented as a complete lifecycle assessment of either laptop.
How it differs
Reuse
Repairability describes how feasible it is to restore a product; reuse describes another use cycle of a product or component. Repair can enable reuse, but an item may be reused without repair.
