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.
Application: AHT is the total average amount of time a CSR spends talking and in post call work in relation to a call. Comprised of ATT and ACW. Tips about using average handle time as a call center metric: AHT is a metric which can be monitored or measured at a CSR, center or enterprise level. Similar to ATT, AHT can be easily manipulated so caution is given to how this metric is monitored or measured.
