Every year, at about the same time, orders go up. The warehouse knows it, sales knows it, the office knows it. Still, when the first heavy week arrives, the team falls behind, extra hours are added and errors rise along with them.

Two weeks later someone says it was a surprise. It rarely is. More often, what was missing was a plan made in advance.

This happens in warehouses, in sales, in customer support and in any place where demand moves with the season. The details differ, but the pattern is the same: capacity was set for a normal day and adjusted only when the busy day was already there.

Count the peak from past years

Before you plan, look at what happened last time. Take the busiest days of last year and write down three numbers: how many orders came in, how many were finished by the end of the day, and how many working hours were used.

Then ask how much more it was and when the increase began. If you do not have last year's numbers, start recording today. A simple table with the date, the number of orders and the number of people present is enough for next year.

The count does not have to be exact. It has to be written down, so the team does not rebuild it from memory under pressure.

Find the first limit

A system rarely fills up everywhere at once. Usually one place reaches its limit before the others: the packing table, the loading door, one person who approves prices, one phone line.

The useful question is not how many people you need in total. It is where the system fills first.

Look at last year's busy day and ask the team where work piled up and where people waited. An extra hour somewhere else does not raise capacity, because the orders still wait at the same table. Add people, equipment or hours where the limit is, then check where it moves next.

A peak is rarely a surprise. Usually it is a plan that was not made in advance.

Rehearse before the big day

A plan on paper is not a tested plan. Two weeks before the peak, do three things.

  • Train temporary staff before the load starts. A person who learns on the busiest day is slow, and so are the people teaching them.
  • Decide what is paused. Work that can wait, such as a full stock count, internal meetings or process changes, is written down and visibly postponed.
  • Name an owner for the peak. One person decides when the team is split, when extra people are called in and when other work stops. Without an owner, every decision goes to whoever is nearest.

A rehearsal day at about 80 % of the expected load shows a lot: where equipment is missing, where an instruction is unclear, where nobody knows who decides. It is cheaper to find this on the Monday before the peak than on the Thursday inside it.

The Area Manager planet has a weekly routine where you can record what was lost and what changes. A Pareto analysis after the peak helps you rank the causes from largest to smallest.

When the peak is over, write three lines: what filled first, what was ready late and what changes next year. Those three lines make next year’s peak easier than this one.
