WebYou've already calculated the start and end times to calculate the wait times, so use that to obtain the turnaround time. For example, A arrives at time 0. The processor is free, so it starts at time 0 and ends at time 6. Then the processor runs B, which had to wait for 5 units, and finishes at time 8, for a turnaround time of 7. WebHere’s a simple average response time formula that you could use: Average response time = (Total time taken to respond to requests during a specific period) / (Total number of responses sent during that period) Since you would calculate response time for every response that your team sends, not just for every ticket, you would need to ...
