Peak orders / hourOrders entering this process during a busy hour that is typical enough to plan around.

Show the math and assumptions

The score compares busy-hour product lines, products per order, batch size, sort space, and variation in order size. It ranks fit; it does not size the cart or wall.

How to read this

The yellow result is the main planning answer. Change any uncertain input to see whether the answer is stable. Treat this as a starting point for a small real-world test, not a promise.

About the score

This ranks which way of organizing the work looks most suitable. It does not predict speed or savings.

Multi-order cart

Pick several orders in one trip, with a separate tote or compartment for each order.

80/100

Pick a batch, then sort it

Pick common products together, then separate them into customer orders afterward.

52/100

Zones feeding a put wall

Workers pick only their assigned areas; a wall or rack brings each order together.

48/100

Count the later work too. Less walking can still be a poor trade if items wait at sorting, must be sent through again, or require extra labor to keep orders organized.

What to check nextBuild a quick tape-and-cardboard version and test it with real order sizes and common problem cases before buying permanent equipment.

After the calculation

Test the answer on a small piece of real work.

Measure today’s result first. Write down what success means, what can go wrong, and how workers will continue if the new method fails.
