TRR can refer to several different things, depending on the context. Here are some possible meanings:

• Treatment, Repairs, and Replacements: In the context of home buying, TRR refers to a phase of the process where the buyer and seller negotiate which repairs or replacements will be made to the property before closing.

• Test Readiness Review: A TRR is a formal review process that assesses whether a system is ready to enter the testing phase. It verifies that the test procedures are complete and compliant with test plans and descriptions, and that required test resources have been properly identified and coordinated to support planned tests. A TRR is normally conducted before each major test configuration item, including hardware and software, and assures management that a system has undergone a thorough test process and is ready for turnover to the next test phase.

• Other meanings: TRR can also stand for other things, such as "Time to Reliably Replenish," "Toilet Ring Remover," "Training Requirements Report," or "Temporary Residence Records". However, these meanings are less common and may not be relevant to the context in which the term is being used.
