The Full form of TAT is Turnaround Time. TAT is the time interval taken for a process from its initiation to its completion. In simple words, it is the time taken to complete a specified process or fulfil a request. For example, the time taken by a shopkeeper for a replacement or repair of a component or equipment. This acronym can be used in various tasks and in multiple situations, as task completion is part of everyone’s life.

Furthermore, it is also considered as a type of performance metric by the companies as they can check, monitor and evaluate the duration from the point a customer has placed an order to its completion and delivery on a monthly basis. The companies nowadays keep on putting efforts to reduce the TAT (Turnaround Time) in order to increase efficiency and customer satisfaction. Metrics based on TAT can be generated for an activity or a task in which the start time and end time can be measured.
