The physical activity level (PAL) is a way to express a person's daily physical activity as a number and is used to estimate their total energy expenditure. [1] In combination with the basal metabolic rate , it can be used to compute the amount of food energy a person needs to consume to maintain a particular lifestyle.
These levels include low, moderate, and vigorous and are measured by the metabolic equivalent of task (aka metabolic equivalent or METs). The effects of exercise are different at each intensity level (i.e. training effect). Recommendations to lead a healthy lifestyle vary for individuals based on age, weight, and existing activity levels.
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
[12] [13] The top level categories are the following: Expert estimation: The quantification step, i.e., the step where the estimate is produced based on judgmental processes. [14] Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data.
A balanced scorecard is a strategy performance management tool – a well-structured report used to keep track of the execution of activities by staff and to monitor the consequences arising from these actions.
An activity can have four elements: input, output, control, and mechanism. [citation needed] At a minimum, activity is required to have at least an input and an output. Something goes into the activity as an input; the activity transforms the input by changing its state, and the activity produces an output.

A skilled operator knows how to measure work, understands the impacts of variability, and knows to stop production for corrective actions when quality falls below specified limits. Accurately measuring this metric with OLE can pinpoint performance improvement opportunities down to the individual level.
