Planning call coverage for a seasonal spike

*October 22, 2026*

Seasonal call spikes are predictable in shape and surprising in size. A coverage plan built from last year's arrivals, answer times, and abandonment gives the team a starting point instead of a scramble.

Build the hour-by-hour baseline

Export last year's call arrivals by hour and day for the same season. Exclude holidays that will not repeat. Note the weeks that were affected by an outage or a promotion.

Plot the arrivals and the average handle time. The product gives the workload, not just the call count.

Add the known changes

List what is different this year: a new product, a price change, a marketing campaign, a location closure. Adjust the baseline for each, and mark the adjustment as an assumption rather than a fact.

Set the service target before the schedule

Decide the answer-time target and the acceptable abandonment rate for the season. Then test whether the proposed shifts can meet them at the peak hours.

If the target cannot be met with the available staff, the decision is to change the target, change the hours, or add capacity. Pretending the schedule will hold is not a plan.

Plan the flex capacity

Identify the people who can take extra shifts, the cross-trained staff from other teams, and the approved overflow arrangement. Record the trigger, the contact, and the cost.

Review weekly during the season

Compare actual arrivals and answer times with the plan. Update the forecast for the following week rather than defending the original number.

Close with the lessons

After the season, record what the forecast missed and which trigger worked. The next plan starts from that record, not from a blank spreadsheet.
