If i take 5000 calls at 78% service level, how many calls would I need to take at 100% to equal an overall service level of 80%

To find out how many calls you would need to take at 100% service level to achieve an overall service level of 80%, we can use a formula that relates the number of calls to the service level.

Here's the formula:
(Number of calls at a given service level) / (Total number of calls) = (Service level at that given number of calls)

Let's solve the problem step by step:

Step 1: Calculate the total number of calls you have taken at 78% service level.
Total number of calls = 5000

Step 2: Calculate the service level achieved with the current number of calls.
Service level at 5000 calls = 78%

Step 3: Calculate the desired overall service level (80%) as a decimal.
Desired service level = 80% = 0.8

Step 4: Use the formula to find the number of calls needed at 100% service level.
(Number of calls at 100% service level) / (Total number of calls) = (Desired service level)
(Number of calls at 100% service level) / 5000 = 0.8

Step 5: Solve for the number of calls at 100% service level.
(Number of calls at 100% service level) = 5000 * 0.8
(Number of calls at 100% service level) = 4000

Therefore, you would need to take 4000 calls at 100% service level to achieve an overall service level of 80%.
