Logistics

Moving things from where they are to where they are needed, on time and intact, at a cost that makes sense.

The idea

How it works

Variability in lead time causes more damage than length. A reliable three-week delivery can be planned around; an unpredictable one-to-three-week delivery forces inventory to be held against the worst case.

Network design determines most logistics cost before any individual shipment is booked. Where things are stored, in how many places, and how far from demand sets the range within which day-to-day decisions operate.

Working with it

In practice

  1. 01

    Measure lead time variability, not just the average

    The spread is what inventory has to absorb.

  2. 02

    Match mode to the promise

    Air freight for a next-day promise, sea for a stocked one. Mismatch shows up as cost or as broken promises.

  3. 03

    Review network design periodically

    It sets the cost floor and is usually inherited rather than chosen.

  4. 04

    Track the last mile separately

    It is disproportionately expensive and it is the part the customer experiences.

The components of logistics

A component is something that exists afterwards which did not exist before — a deliverable or a mechanism, not an intention.

  1. The network

    Where things are stored and moved, and how far that is from demand.

  2. The lead time record

    Actual times with their spread, not just the quoted average.

    Learn
  3. The cost per movement

    What it costs to move a unit, by mode and leg.

    Learn

Unpredictable lead time costs more than long lead time, because inventory has to cover the worst case.
