In the context of postal operations, what does 'productivity' primarily refer to?

In postal operations, 'productivity' primarily refers to work efficiency, which encompasses how effectively resources are utilized to achieve desired outputs. This concept involves a balance between the amount of work performed and the time or resources expended. When a postal operation is efficient, it can handle more mail volume with the same or fewer resources, leading to enhanced overall productivity.

Work quality, while important, does not directly measure productivity; it’s more about the standards of output rather than the efficiency of the process. Time use is a factor in how efficiency is calculated, but it does not fully capture the broader concept of productivity, which includes not just the time taken, but also how well tasks are completed in relation to the resources used. Cost reduction can lead to improved productivity, but it's more a consequence of efficient practices rather than a direct measure of productivity itself. Thus, work efficiency is the most aligned description of what productivity entails in the context of postal operations.
