Warehouse Management,

Why Are KPIs Important in Warehousing & Fulfillment?

Warehouse business is a back-end operations business. You don’t control sales, only deliveries. The efficiency of the operations is the key to extracting maximum profits from a warehouse. So you need to know that you are getting maximum return on your investment in this business, just like any other business. But since most of it is a fixed model, B2B business with caveats of B2C (retail deliveries), you need to understand and measure the nitty gritty of the warehouse operations and fine tune them. That’s where the KPI or Key Performance Indicators come in.

A right det of KPIs tells you the detailed performance of your warehouse. Couple it with past indicators, your forecast of business growth and you can figure out where you are heading in future. For example if you are already at maximum space utilization, you cannot expand. A client whose business is growing very fast will need more space. If you can not offer him more space, he will go to someone who has more space. That will reduce you space utilization and also your revenue. Not to mention, you now need to get your sales to run and find a client who can utilize the now freed up space. So while on the face of it a full utilization of warehouse space sounds good, it is not good for a growing business. That is why, it is not only important to have the right KPI, but you also needs to set the right standards for those KPIs. Standards should be the ones that work for you. (Is 80% space utilization good for you, or you prefer 95%?)

Similarly, KPI also help you in benchmarking. benchmarking tells you how good you are doing as compared to others in the same industry. If your KPI is below the industry standard, that means you are not utilizing your warehouse to the best possible extent. You might be making money, but lower KPI means that you are leaving money on the table. You could get more profits by improving those KPIs. On the other hand if you are beating industry KPI but still not making money, something else is wrong somewhere. A well designed set of KPI itself would direct you to where to look. If you are beating the KPI and making money, it looks like a good sign. But it can also mean you are stretching yourself. If you are extracting higher productivity from your machines and spending less on maintenance, you might have to bear a high depreciation and replace the machines faster. If your order cycle time is very less, you might not have any contingency built into the process. That is risky.

Whether you want to stay with the industry benchmarks or set your own benchmark standards, is entirely up to you. While industry benchmarks are there for a good reason, (most of the industry works at those levels) you don’t have to be bound by them. Your KPIs will vary depending on your niche value proposition and your operating model. For example if you specialize in handling delicate products that need more space for storage, your floor utilization will be lower. Also, the KPIs for 2PL warehouse will be very different from the KPIs for 3PL warehouse.

The Supply Chain Operational Reference Model (the SCOR Model), created by Supply Chain Council, provides for over 200 KPIs for monitoring the overall performance of a supply chain. These are broken into various levels to get more granular picture of the business. Some of these could be used for measuring performance of a warehouse as well. Research them to identify which one are suitable for you. Now that we understand what KPIs means and why we should measure them, let’s look at some of the key KPIs for warehousing business.

The main KPIs for a warehouse should focus on Receiving, put away, storage, pick and pack and shipping.

Inventory Accuracy: What is the accuracy of the workers when preparing the product (or order). It is measured by taking the headcount of the items in the stock and comparing it with what’s recorded in the books. This one has direct impact on your working capital and order fulfilment capacity.

Perfect Order Rate: This measures the number of orders shipped to the customer without any incident. The incident could be damaged goods, inaccurate orders, late shipment etc. Needless to say, this one tells you how well is your warehouse operating where it matters the most, the final fulfilment of order, shipped out of the warehouse.

Productivity: This measure tells how many orders are ready to be picked up by the shipper, per hour. Depending on your warehouse business model, it could the number of orders per hour, or total line items per house or it could be the total dollar value of the orders per hour.

Equipment utilization: This one tells about how well your equipment is being utilized. Underutilization of the equipment means you should stretch it more and achieve more. Overutilization mean higher maintenance and replacement costs. Idle equipment depreciates without giving any return. Over utilized equipment can lead to breakdowns and stop the whole chain, leading to higher losses. Your equipment must be running at the optimum rated utilization to extract maximum value from it.

Cycle time: This KPI measures the total time taken since the material came in as inventory and was picked up by the shipper for delivery, as a part of the order. The shorter the cycle time, the lesser the money tied up in working capital. An end to end cycle time would include the transit and transportation time taken by the shippers for the final delivery to the customer’s premises.

Average cost per order: This KPI measures how much are you spending in running the warehouse. It is calculated as total orders fulfilled divided by the total cost incurred for the warehousing operations. The costs include the manpower costs, cost of rejects and returns absorbed by warehouse, cost of damaged products that are absorbed by warehouse, variable costs for running the warehouse (utilities, taxes, rents, insurance,), equipment cost (consumables and depreciation for large equipment) and all other costs. This should be always be as low as possible, as it eats straight into your profits.

There are many other KPI that you can measure to understand the efficiency of your warehouse operations. The finer the KPI, the deeper the control it can provide. However, at a bare minimum, you must keep an eye out for the top line (revenue), the bottom line (profits) and ROI (return on Investment).
