Abstract: In an embodiment, a method comprises: retrieving, without direct observation, one or more activity measures recorded within a particular time period and associated with activities performed by a group of analyzers in a specimen analysis laboratory; transforming the activity measures into a count of activities performed by the group of analyzers within the particular time period; determining whether the count of activities for the group of analyzers is less than a peak value for the group of analyzers; in response to determining that the count of activities for the group of analyzers is less than a peak value: determining a spare capacity value for the group of analyzers for the particular time period as a difference between the peak value and the count of activities for the group of analyzers; causing generating a first display of the spare capacity value for the group of analyzers on a computer display unit.
