TRRs

TRR is an acronym used across multiple disciplines to denote different concepts, and there is no single universally accepted definition. The intended meaning typically becomes clear from the context in which it appears.

In medicine, Targeted Radiopharmaceutical Therapy is a class of treatments that delivers radioactive compounds to cancer cells via targeting molecules. This approach aims to maximize the radiation dose to tumors while limiting exposure to healthy tissue.

In environmental policy and waste management, Total Resource Recovery describes strategies designed to reclaim energy, nutrients, and materials from waste streams. The goal is to support a circular economy by extracting maximum value from resources before disposal.

In engineering, aerospace, and large-scale programs, Technology Readiness Review or Technical Readiness Review are formal evaluations of whether a technology or subsystem has matured enough to proceed to the next development phase. These reviews assess design stability, integration risk, and manufacturing readiness.

In software and systems testing, a Test Readiness Review is a checkpoint that confirms test plans, environments, and data are prepared before formal testing begins.

Because TRR has multiple usages, readers should consult domain-specific documentation to determine the precise meaning in a given context. The term’s exact interpretation can vary notably between fields such as medicine, waste management, engineering, and software testing.
