Langerhans' cell histiocytosis can manifest as three distinct clinicopathologic entities: acute disseminated Langerhans' histiocytosis (previously known as Letterer-Siwe disease), unifocal Langerhans' cell histiocytosis (previously known as eosinophilic granuloma).
average handle time (AHT) Average handle time (AHT) is a call center metric for the average duration of one transaction, typically measured from the customer's initiation of the call and including any hold time, talk time and related tasks that follow the transaction. AHT is a prime factor when deciding call center staffing levels.
Occupancy can be a good metric to use in judging whether agents are working too hard or too easy. In my view, occupancy is an outcome of the staffing, call demand, average handle time and service level goal. In general, as service level increases (goes up), occupancy will decrease (go down) for a given call demand.
