Productivity measurement is complicated by __________.

Productivity measurement can be complicated by the lack of precise units of measurement. This is because productivity typically involves quantifying outputs relative to inputs, and without clear and consistent metrics, it becomes difficult to assess efficiency accurately. For example, if outputs are measured in different ways across various departments or sectors, it can lead to inconsistent evaluations of productivity. This lack of standardization makes it challenging to make meaningful comparisons or improvements, as varying definitions of what constitutes an output or input can obscure true performance levels.

The other factors mentioned do play roles in productivity, but they do not impact measurement in the same fundamental way as the lack of precise units. For instance, while the high cost of technology may influence the decision to adopt certain tools for measuring productivity, it does not directly complicate the measurement itself. Similarly, overemphasis on output quality and the number of employees can affect productivity outcomes and perceptions, but they do not inherently create complications in the measurement framework itself.
