Understanding the Mismatch Ratio (MMR)

Nothing lasts forever. You know it, I know it, designers and manufacturers know it... and often intend it. Single-use items, packaging and containers, casing for consumer electronics, all of these are intended for use over a limited and specific amount of time. So, why then are these products built from materials that far outlast that timespan? The temporal component of design is rarely considered, and if it is, engineers and designers use materials that last for centuries "just to be safe." But, taking stock of the results of these design choices, it becomes strikingly clear that we need a new conceptual framework.

The Mismatch Ratio (MMR) is that framework.
