Thanks for downloading our e-book about warehouse productivity. As the title suggests, this guide is all about warehouse efficiency, how good design principles and management can help your business run smoother and more profitably and enable you to grow and expand.

In the chapters that follow we’re going to take a look at how you can analyse your current operation and see how you are performing, before going into practical ways for you to boost performance in your warehouse and beyond. The goal of each suggestion is to make your life easier by using sound principles and technologies to save you time and money.

We’ve broken this guide into short sections to keep the information as succinct and targeted as possible. This is above all things a practical guide – it isn’t a book about logistics theory. We appreciate that, as important as warehouses are, it is best when they perform their functions effectively, and you don’t have to think about them too much.

This is the end goal of warehouse productivity management: to establish a warehouse that integrates with the rest of your business and acts as a powerful asset for achieving your company goals.

The Warehouse Productivity Guide

Chapter One: Is Your Warehouse Fit For Purpose?

With this all said and introductions made, let’s get straight down to business and talk about YOUR warehouse. Specifically, is it fit for purpose and how do you know?

When To Know It’s Time To Move.

There isn’t any arcane secret to an efficient, well-run warehouse. Whatever logistic issues you may come up against, chances are that there are a number of different solutions you could try. Some of this will depend on your budget, on your existing logistics infrastructure and the preferences of your business.

Whatever your current setup, we can work with you to help you improve efficiency. Whether you have a single warehouse or a nationwide network, there are always improvements you can make without having to start from scratch. Sometimes, of course, it is time to move or expand, and we can advise you on this as well.

So we can illustrate the principles of good warehouse design, let’s assume for the moment that you intend to move to a new warehouse. . How do you go about designing it for growth, flexibility and productivity?

Designing Your Warehouse for Growth and Flexibility

When advising clients on a new warehouse design we look at the following nine points; the same principles that we apply when advising a business on how to improve an established operation.

1) Understand Your Requirements: Begin with a firm understanding of what you want your warehouse to do. What does your business need from a warehouse? No two companies will give the same answer to this, so take a look at your product range, your throughput and the needs of your customers. This can be done in four steps.

  • Step One) Start by reviewing your SKUs, looking to trim down your stock profile to get rid of redundant lines and focusing only on what you actually need.
  • Step Two) Next, pay attention to your customer demand levels throughout the year. Average throughput and demand are frequently misleading, as most businesses experience greater or lesser demand for different products at different times of the year. This will lead to peaks and troughs in
    throughput and stockholding levels.
  • Step Three) Plan your warehouse not only for where your company is now, but where you plan to be in 5, 10, 15 years time. Make sure your new warehouse can accommodate expansion plans, new product lines and new technological innovations, without having to start all over again. Future proofing your warehouse in this way will encourage your company to innovate and expand as new opportunities arise.
  • Step Four) Plan for changes in your suppliers. Your supplier relationships, good as they are at the moment, may not always remain the same. Their business may change, products be discontinued or manufacturers go out of business. As your stockholding profile changes, so will your supply partners. With each supplier will come different lead times, order quantities, returns policies and so on. Set your warehouse up so that it is flexible enough to accommodate your stockholding profile as it changes over time.

2) Designing from the Inside-Out: Your greatest outlay when building your new warehouse will be the physical building itself, as well as any related mechanical material handling systems attached to it. Moreover, once erected, the fabric of the warehouse will be very difficult to change. When designing a new warehouse you are in a privileged position, as you have the luxury of creating the building to accommodate your processes, products and equipment, rather than simply making the best use of the space you already have. We call this designing from the inside out. Defining your requirements first, to
ensure optimum performance and then designing the warehouse envelope structure, enveloping the operational area.

The Warehouse Productivity Guide

3) Standardise your Units: Depending on your industry, you may measure your storage/transportation units in terms of pallets, ISO freight containers or totes. For almost all organisations, managing your warehouse in terms of collective unit loads makes for a more effective use of space than measurement in individual items. When designing a warehouse, standardise the units you use to match your product profile, with as few variations as possible. This ensures you can use all your warehouse space in a flexible way. You should also make sure these are compatible with the industry standards prevalent in your market. 

4) Make The Best Use Of Your Space: Physical space, not just floor area but also the cube, is the most valuable asset you have available in your warehouse, so design your area to be as cost-effective as possible. Designing from the inside-out, understand your products first when considering how to use your space. Analysis methods such as Pareto Analysis can categorise your product lines based on their storage requirements, throughput and handling needs. These can then suggest suitable space utilisation methods and stock rotation systems to make sure your storage and handling areas are well planned. Choosing the right equipment is also important. The majority of your warehouse space will be devoted to product storage and movement. You should therefore invest in versatile, appropiate equipment with a small space footprint and good productivity output.

5) Establish An Efficient Flow Process: When moving stock, plan for the quickest and most effective route between A and B. There are two main ways to do this, by using a Through Flow or U Flow layout. The choice you make depends on the layout of your stock, organised by product popularity or in sections of similar units (family groups). Your logistics process also influences it; for instance. how the stock is received, stacked, picked, packed and dispatched within the warehouse and the number of doors required. You also need to establish the most efficient means of carrying out this movement, with the idea that each handler or vehicle should travel the shortest possible distance to carry out their task. You don’t want your team to waste time and energy making inefficient journeys.

  • Short movements are best carried out by hand trucks or trailers.
  • Medium distances can be facilitated by forklifts and other power trucks
  • The most efficient way of moving stock over longer distances is some kind of
  • conveyor system or Automated Guided Vehicle (AGV)
  • Or a hybrid of the above dependent on the volume throughput
The Warehouse Productivity Guide

6) Design For Productivity: Each warehouse-using business will decide on a staffing level that suits its requirements. Some of our clients have highly automated their warehouses to minimise human involvement, while others retain large warehouse teams potentially to enable maximum flexibility. The
key here is always to maximise employee productivity, and this is something that can be quantified in advance and then measured against wage rate to
ensure a good ROI. Identify processes where changes can be made, such as order picking, and look for means by which time can be saved and labour costs reduced. When designing a new warehouse, you can establish your space with efficient processing in mind. For instance, you can minimise the length of your picking route, introduce staff incentives and bonuses to increase productivity, or implement IT systems that automate parts of the process. Revised KPIs should always be accompanied by appropriate training and incentives to keep your staff motivated.

7) Design Your Structure: Once you’ve established clear processes, stock control procedures and optimum staffing levels, you can design the physical structure of your warehouse to accommodate them. Following the principle of designing from the inside-out, the internal structures come first e.g. the grid of structural columns and roof clearance with the required operating height. What follows are the floor loadings, loading docks and internal structures, such as mezzanine floors, lighting levels and storage units. Finally, the peripheral elements of design, which extend to administrative offices, staff facilities, battery charging, fork truck park up, valued added activities etc.

8) Reduce Access Congestion: Designate your external areas so that supply and delivery vehicles can come and go unimpeded. The usual suspects that contribute to congestion and delays are your employee’s cars, pedestrian traffic, and stored empty pallets, cages and waste. When designing a new site, plan to keep your walkways and staff car park well away from your delivery area, it’s much safer, and assign specific places for waste and empty units. Pay attention to vehicle flows on the site, one way directional and no blind side reversing onto docks. Plan your space to accommodate future expansion, so that your area doesn’t become overdeveloped and congested.

9) Futureproof Your Warehouse: No business can claim to be resistant to change. Your market, your customers, your suppliers and the profile of your workforce will change over time. When designing your warehouse, establish dynamic processes and policies that can accommodate change and are resilient to developments in your business. The physical environment of your warehouse should reflect this. Our consultants can help you take an uncertain future into account when creating a responsive warehouse solution for your business. 

10) Maximise Real Estate Value: You should also never forget that your warehouse is an important property asset, worth hundreds of thousands, if not millions of pounds in resale value. At some point, you may wish to sell your warehouse to another company or let. Your design should therefore have one eye on market value – how you can maximise the price you can demand from future owners. So the design may want to reflect institutional standards that provides flexibility for different types of users.

Chapter Two: Optimising Your Logistics: 10 Ways To Improve Performance

While the last chapter took you through the principles of good warehouse design for new facilities, this section is aimed at businesses who want to improve the performance of an existing warehouse. Fortunately, you don’t have to start from first principles every time. Here are ten ways you can optimise your logistics for a highperforming warehouse, regardless of what the economy is doing.

Managing Your Inventory

Most of your net worth as a business is tied up in the inventory you hold. There are costs associated with ownership, both in terms of maintaining your stock and in providing warehousing. Therefore, managing your inventory to reduce unnecessary holdings and ensuring you have space for the products that have demand, is a great way of improving cost effectiveness and wasting less space.

  1. Identify and dispose of stock that hasn’t been moved since the last order cycle: Lack of movement is a sign that the stock line may have become obsolete. At the very least it is a sign that demand is falling, which should be reflected in future orders.
  2. Review the frequency of orders and purchase quantity: With these stock lines, adjust your orders to reflect actual demand. In fact, this is a good principle to follow across your product range. By purchasing more frequently, but in lower volumes, you help to avoid the problems of redundancy that come with falling demand.
  3. Reduce the amount of stock you hold: Holding to the principle above will allow you to reduce your overall stock, thus requiring less space and lower warehousing costs. This reduces the danger of obsolescence and overstocking. Prioritise only your most popular products for stockpiling, purchasing other lines to reflect customer demand.
  4. Centralise your stocks: Do you have more locations than you really need? The more warehouses you operate, the higher the support and infrastructure costs you will have per SKU. For instance, maintaining stock at four warehouses will require double the level of safety stock than if you had one central location. Closing a location is not always the answer and shouldn’t be undertaken lightly, but every asset and distribution centre should demonstrably contribute value to the business. If they don’t, and distribution costs don’t outweigh the savings , then centralisation is an option you should consider.

Improving Your Warehouse Infrastructure

Reducing and centralising your stockpile opens the door to improving your warehouse infrastructure by streamlining your inventory, administrative, security and management processes.

  1. Invest in modern storage and handling systems: Smart investment in modern handling, storage and security systems can drastically improve the cost effectiveness of your operation, as well as reducing staffing costs. As we will examine again in the next chapter, a technology-augmented warehouse is
    far more efficient than one that depends on human labour alone.
  2. Review your operational procedures: A comprehensive review of your warehouse structure, compared against your actual stock requirements, sets you up to review your operational procedures. The savings you can make here are very useful; including significant reductions in management costs, wasted space and surplus workforce. At the end of this review process, you may also find you have surplus assets, meaning you may be able to unlock additional income through letting out unused warehouses, or space within an individual warehouse.
    The Warehouse Productivity Guide
  3. Outsource some of your warehousing or transport functions: You can potentially save a lot of money by outsourcing some of your warehousing
    and logistics functions to a third party. Our consultants can advise you on choosing the right 3PL partner for your business, including creating a
    watertight service contract.

Improve Your Logistics And Cut Transport Costs

Looking at the big picture, you will see there is a trade-off between savings in one department, versus increased costs in another. For instance, reducing the
number of warehouses will yield savings in terms of storage and handling, but will increase transport costs, whereas having a wider storage network will cost more in warehousing but will reduce transport expenses.

  1. Find the optimum number of warehouses: How do you strike the right balance? This is where it is handy to get advice from logistics specialists. Businesses, such as ours, use computer modelling to find the optimum logistics network for your company. We can also accurately model the economic impact of closing one or more locations, if you are considering rationalising your warehouse locations.
  2. Optimise your transport planning process: The same planning software can help you mould your transport network to boost its performance. This enables you to make the best use of your available fleet, planning the most economic routes and setting up efficient delivery schedules. Custom
    designed software can computerise logistics route planning, to make the process far less labour-intensive and enable you to review transport strategy on a weekly, or even daily basis.
  3. Improve the performance of your logistics fleet: At the same time as software modelling can help your route planning process perform better, technology can also help you get more out of your fleet while it is on the road. Telematics are monitoring systems installed in your lorries that
    monitor metrics such as fuel use, driving practices and maintenance issues. They enable you to train your team to encourage sustainable driving practices that reduce fuel consumption, and are kinder to both environment and engine. Telematics also alert you to potential maintenance issues, allowing you to set up a schedule of preventative servicing.

Chapter Three: Better Warehouse Management - Software to Save You Time & Money

We delved into the world of planning software in the last section with our discussion of logistics route management. The good news is you can also use
software applications to help you manage your warehouse more effectively, saving money across a number of processes.


This chapter will review the benefits of investing in a Warehouse Management System (WMS) for your business:

The benefits of a Warehouse Management System (WMS)

  • Reduced Labour Costs: The company payroll is usually a business’s largest on-going cost, and the bad news for warehouse owners is that logistics is traditionally extremely labour-intensive. The busier your warehouse, the more staff you’ll need on site (often in shifts) to handle the throughput. A WMS can help reduce overall staff costs by forecasting peaks and troughs in demand. This means you can accurately assign the right number of staff to
    handle your operation at any given time, while boosting productivity and reducing overstaffing. Planning for your natural demand cycles also means you won’t find yourself understaffed, saving you the expense of having to hire additional temporary staff to handle busy periods
  • Reduced outlay on equipment: A reduced and more targeted staff require proportionally less equipment to carry out their role. This is another big advantage of implementing a WMS. A reduced equipment pool requires less maintenance and fewer outlays on new capital purchases.
    The Warehouse Productivity Guide
  • Accurate Inventory Management: A WMS allows for laser sharp inventory management, establishing levels of product to meet customer demand. You can therefore avoid the dual problems of overstocking on one hand, and forcing customers to endure long lead times while you order products on demand, on the other. Accurate inventory management means always having in-demand stock available when you need it, meaning you can minimise overall stock levels, reduce space and cut equipment and staff costs
  • Make full use of your facilities: WMS platforms are designed to help businesses facilitate and manage growth. A key part of growth for a retail or warehousing business is adapting their warehouse and logistics network to cope with growing volumes of inventory. A full and on-going analysis of your available space through the WMS lets you improve your stock rotation processes, use your facilities more effectively and decrease your overall space requirements.
  • Real-time reporting: A well-configured WMS gives you access to real-time reports across a range of crucial metrics. The importance of this monitoring and reporting facility could hardly be overemphasised. Productivity reports allow you to improve your processes and operation over time and give you sound advice when making investment decisions. Furthermore, WMS reports predict stock control issues, meaning that inventory can
    be back ordered, or additional stock purchased in response to a spike in demand. The hidden hand of a WMS removes all the uncertainty from warehouse management, allowing for steady increases in quality, control and levels of efficiency.

Chapter Four: Tracking The Right Metrics

You have invested in a high-quality WMS and are keen to benefit from all its reporting functions. Which Key Performance Indicators (KPI’s) are the most useful ones to keep an eye on for businesses wanting to run an efficient operation? There are hundreds of different metrics that you can measure with a WMS, but for us these are the top five:

Five Important KPIs for Warehouse Management

1) Inventory Cost: Your warehouse inventory represents a significant cost to the business, not merely in terms of the retail value of the products, but also in capital cost, risk, insurance, servicing costs and obsolescence. Taking these considerations into account gives you the carrying cost of your inventory, which is useful to quantify.

The figure is arrived at by the formula: Inventory carrying rate X Average inventory value = Carrying Cost (This metric is useful for helping you forecast demand and stock turnover)

The Warehouse Productivity Guide

2) Inventory Turnover (Stock Turns): Measuring your inventory turnover rate allows you to assess your ordering practice. Which product lines are in greater demand than others? Are some stocks approaching obsolescence? Your WMS will allow you to keep a handle on this in real-time, adjusting your inventory to maximise turnover. As a metric, inventory turnover defines the number of times a warehouse gets through its complete inventory in a year.


The formula is: Cost of sold goods / Average Inventory Cost= Inventory Turnover


You can measure your inventory turnover figure against competitors and industry averages to gauge your comparative performance and see where improvements can be made.

3) Inventory to Sales Ratio: Your business cash flow is largely dependent on the income received from sales versus the expenses of replenishing your inventory. This is your inventory to sales ratio and why it is important. Monitoring this figure - for instance if inventory levels rise while sales figures drop – can help you predict and prevent cash flow problems. More positively, it could also help you predict a spike in demand, allowing you to make sure you have enough stock to satisfy your customers.

Here is the formula if you wanted to take a DIY approach (Your WMS will do this for you) Inventory balance /calendar month sales = Inventory to Sales Ratio

4) UPT (Units per Transaction): By monitoring your average UPT you can assess the performance of your sales team over time, as well as changing trends within your market. For some businesses this figure is fairly stable, while for others it changes quite drastically at different times of the year. Understanding this figure provides useful information for sales and marketing teams, leading to new strategies to boost sales. It can also help you plan the best use of space when rationalising your warehouses or building new premises. UPT is calculated by a simple equation:

Units sold /Number of transactions = Units per Transaction

5) Returns rate: No one likes to think about returns, but they are an essential part of any cost analysis for warehouse operations. It is therefore one of the most important KPIs you can measure. A high rate of return is always a cause for concern that warrants further investigation. A WMS will log a cause of return next to each incident, so you can see how many returns are the result of damage, wrong shipment, and late deliveries, faulty products and so on. Understanding the cause of returns empowers you to take specific action to bring down your overall returns rate. Calculate your Rate of Return by:

Returned Units / Total Units Sold

Why track KPIs?

Keeping track of these core KPIs and taking the appropriate remedial action can visibly improve warehouse performance within a short period of time. At every level of your operation, efficiencies can be made; costs reduced and customer service improved. Once you have established a well-designed and closely managed warehousing operation, monitoring performance ensures you keep on top of your game by making continual adjustments whenever they are required.

Chapter Five: Assessing Your Warehouse Performance

After reading through this guide you may be having a few thoughts, and maybe even some worries, about how your warehouse is performing. If so, that is no bad thing. Even the most efficient and well-run warehouse operations can benefit from a few changes here and there to tighten up the process. When you are ‘in the thick of things’ managing a busy warehouse operation, it is easy to develop blind spots. This happens in any line of work. For instance:

  • Are you using the most recent warehouse and logistics management processes? When was the last time your methods and procedures were reviewed?
  • Are your IT systems adequately supporting your warehouse operation?
  • Are you spending too much money maintaining an out-dated software platform?
  • Could your route planning system be more efficient?
  • How does your actual performance compare to what you could potentially achieve with your facilities?
  • How do you benchmark your performance against competitors and industry standards?
  • Is your warehouse layout making the best use of space?
