A labor management system, usually shortened to LMS in warehousing, is software that measures the work each person does against a standard for that work and reports the difference. A WMS knows that an order was picked; an LMS knows how long it should have taken, how long it did take and therefore how the picker, the shift and the building performed. The phrase labor management system lms is the warehouse product, distinct from the learning management systems that share the acronym, and lms warehouse is the same thing searched from the other end. This page explains what is a labor management system in that sense, what it needs from the WMS to work and what a small operator can measure with a worksheet before paying for the software.
What a labor management system (LMS) measures
Every task the WMS records, a pick, a putaway, a receipt, a count, has a start and an end in the scan log. An LMS labor management system reads those timestamps, attributes each task to the person who scanned it and compares the time taken with an engineered or historical standard for that task. From that it produces performance per person, per shift and per client, utilization, the share of paid time spent on measured work, and the cost of each activity at the loaded rate. The standard is the whole thing: an LMS with a wrong standard measures precisely the wrong number.
What LMS warehouse software adds to a WMS, and needs from one
The WMS/LMS split is simple: the WMS supplies the scan log and the tasks; the LMS adds the standards, the comparison and the reporting. Without scans at each step there is nothing to measure, so LMS warehouse systems presume a barcode WMS already in place and working. What it adds is the ability to staff a shift from a standard, to see which client's work runs slow and why, and to pay or coach against measured performance rather than impression. A small operator gets most of that from a spreadsheet and a weekly habit; the software earns its price when the building has more people than one supervisor can watch.
The standard you can set today, without an LMS labor management system
The free labor standard worksheet on this site does the arithmetic an LMS automates: from the lines picked and the labor hours worked on a client's account it reads lines per hour, and from a standard, a shift length and a utilization it reads how many pickers a day's orders need and what happens if the standard is missed by a tenth. That is the labor management layer of a WMS, worked from the operator's own figures with no vendor named and no industry rate assumed. Pickpathly Pro keeps the standard against the client with its history, so a change in the standard is a dated decision rather than a drift.
Questions people ask about what is a labor management system
What is LMS in a warehouse?
A labor management system: software that reads the WMS scan log, measures each person's work against a standard for that task and reports the difference. It is not the learning management system that shares the acronym.
What is the difference between an LMS and a WMS?
The WMS records what was done and where the stock is. The LMS reads the WMS scan log, compares each task with a standard and reports performance, utilization and labor cost. One is the record; the other is the measurement of the people making it.
Is a labor management system the same as a learning management system?
No. Both are called LMS. In warehousing, LMS means labor management, the measurement of work against standards. A learning management system delivers training courses and is a different product.
Does a small warehouse need an LMS?
Not on day one. A barcode WMS plus a measured standard per client and a weekly worksheet gives a small operator the staffing and cost figures. The software earns its price when there are more people than a supervisor can watch.
