A call center has 100 agents working an 8 hour shift. On average each agent handles 20 calls per hour. Calculate the design capacity of the call center in terms of call per day?

First, calculate the total number of calls handled by one agent in an 8-hour shift:
20 calls/hour * 8 hours = 160 calls/agent

Then, calculate the total number of calls handled by all 100 agents in an 8-hour shift:
160 calls/agent * 100 agents = 16,000 calls

Finally, calculate the total number of calls handled by the call center in a day (assuming a 24-hour operation):
16,000 calls/shift * 3 shifts/day = 48,000 calls/day

Therefore, the design capacity of the call center in terms of calls per day is 48,000 calls.
