Advice You - Inventory Reduction - A How To Guide
INTRODUCTION
INVENTORY is the largest single asset on the balance sheet of many manufacturers and distributors. It is usually the most expensive asset to own and maintain as well, with estimates of carrying costs typically running 25-30 cents or more on the dollar annually. Therefore, any useful suggestions to optimize INVENTORY investment and associated expenses would be most valuable.
The paper addresses how to manage INVENTORY investment to optimum levels, which means a reduction or major redistribution of it in most companies. Optimal INVENTORY levels come down as management makes the operation more efficient by improving processes, reducing lead-time, managing supply and demand better.
One can’t “attack” INVENTORY effectively, but only its underlying causes, which will be discussed. Most INVENTORY “problems” are merely a reflection of management, design, process or operational problems. Current literature on Just-in-Time and World-Class Manufacturing addresses how inventory reduction is a by-product of doing things right the first time.

INVENTORY is a major capital investment affecting cash flow and profitability. Inventory comprising one-third to one-half of companies’ total assets isn’t unusual. There are significant expenses associated with possessing it. INVENTORY reductions can do more to improve ROA (Return On Assets) in most companies than most other factors. For instance, a 50% reduction in
INVENTORY will typically account for a 10-25% improvement in ROA! Certain industries, such as aerospace and defense, widely believe that INVENTORY is a non-issue, because they receive “progress payments” from customers or because they “write-off” job-end variances and leftover “residual” inventories. The facts are that these companies need to watch inventories even more closely but first they need to be made aware that there are INVENTORIES to watch.
Excess inventories subject the manufacturer to additional liabilities for things such as obsolescence, rework, storage charges, etc. Most of these ultimately end up “written off” and are applied to “overhead”, but this eventually raises the overhead rate, which increases costs of doing business, wh

Carrying Costs
Let’s look at what goes into INVENTORY “cost of ownership”, frequently called the “carrying cost” and expressed in terms of percent cost of INVENTORY valuation per year of ownership. For example, a 25% carrying cost would indicate that it costs about $.25 to own each $1.00 of INVENTORY each year. These costs consist of:
• Cost of money – The cost of capital to the company or, in some cases the “opportunity cost” or return that could be earned on the money by applying it productively elsewhere. The cost of money has ranged anywhere from 6% to 18% in the last 25 years. Obviously, cost of money has a very significant impact on investment strategy.
• Obsolescence – The risk of INVENTORY never being used, or needing rework to make it usable, needs to be factored into the cost of owning INVENTORY. In theory (and practice), the larger the INVENTORY is, and the longer it is held, the more likely engineering changes, customer preferences and technological changes will render that INVENTORY unusable.
• Shrinkage – A portion of INVENTORY becomes unavailable

to the owner due to loss, damage, theft or spoilage. The longer INVENTORY is there and the more there is, the more likely this is to happen. Steps to prevent it only raise carrying costs in other areas, such as security, air conditioning, better control systems, recruiting policies, etc.
• Quality Factors – Allowances for yield, attrition, scrap and rework. This is really more of a function of the process than the amount of INVENTORY invested and is more related to throughput, but is usually expressed as part of the aggregate INVENTORY carrying cost.
• Technological or Price Obsolescence – Prices don’t always go up. In fact, in industries such as electronics, prices often plummet due to constantly improving designs, product and process technology improvements. Therefore, it is desirable to minimize inventories in high-risk areas.
• Taxes – There are two dimensions to this: 1) In some areas, a tax is levied on inventories, so the more INVENTORY, the more tax is paid. 2) INVENTORY is regarded as an asset by most accounting and tax rules.

• Insurance – The cost of carrying insurance on INVENTORY needs to be considered, as well as insuring the space, equipment, people and other resources needed to control it.
• Space – Costly storage space sometimes occupies 25-30% of the total facility, when one considers raw material warehouses, stockrooms, work-in-process storage, receiving, shipping, outside warehouses, MRB and residual storage areas. INVENTORY reduction campaigns frequently help companies avoid the need to move to large facilities, or permit them to shut down or cut back existing facilities.
• Manpower – All of this INVENTORY needs people to order, receive inspect, record, move, count, store, retrieve, post it to the ledger, etc. People are the largest or second largest expense (behind material) for most manufacturers.
• Record Keeping Systems – Software, procedures, equipment and paper must be used to stay on top of INVENTORY.
• Material Handling/Storage Equipment – Conveyors, fork lifts, bar code readers, scales, AS/RS, trucks, carts, bins, racks, shelves must all be purchased, leased, maintained and cared for.

Reconciliations – Must be conducted to ensure that inventories are properly accounted for and maintained.

WHAT AFFECTS INVENTORY?
One must “know thine enemy” to successfully deal with it. Now that we’ve discussed the significance of INVENTORY, let’s determine why it exists and what makes it go up or down.
INVENTORY is not always evil. It usually exists for a reason, however a reason is not always true justification. INVENTORY is frequently kept as a buffer and masks other problems.
Major Reasons for Inventory
• Net Demand – Demand derived directly from customer requirements or internal demand.
• Pipeline – INVENTORY needed to sustain the process over its cumulative lead-time through all operations and holding points. Also included in the pipeline are paperwork operations, such as billing, which

• Quality – Yield, attrition, scrap, rework allowances impacting amount of inventory and time inventory is in process.
• Lot Size – Lot size considerations include vendor minimum order quantities, raw material and manufacturing lot sizes due to setup and other nonrecurring, lot-related cost considerations and run time impact considerations.
• Supply Buffer – Extra INVENTORY carried as a hedge against unreliability of vendor or factory schedules, inaccurate records, unpredictable quality or other fluctuations tending to reduce reliability of providing materials on demand.
• Demand Buffer – Extra INVENTORY planned due to uncertainty of the true requirement need date or quantity, which may vary due to poor forecasts, transportation problems, or various contingencies.

• Product Design – A product design that minimizes the number of parts, picks easily obtainable materials and components, lends itself to manufacturing with the simplest possible facilities and equipment will minimize INVENTORY costs over the long pull.
• Materials Supply – Specifying quality materials, well suited to the process and application, with easy availability, low prices, reliability of supply and short response time are all big advantages that can facilitate INVENTORY reduction. Having the best sources for key materials or changing existing arrangements can do a lot to help minimize inventories.
• Processes – Good, reliable processes will help reduce INVENTORY, because they will help reduce scrap, rework and attrition, and also provide a more reliable flow of supply, which will help reduce buffer stocks, safety stocks, safety lead time INVENTORY and eliminate much accumulation of INVENTORY on the production floor.

rly. Widely scattered plants, multi-story buildings with inadequate material flow capabilities and processes distributed over many different departments, all increase the amount of part travel, possibility of loss, delays and need for manpower and extra equipment to support the process.
• Service Objectives – The required response time and reliability of service to customers has a big impact on INVENTORY costs. For instance, if industry standards allow making to customer specifications from scratch, there may be less need to maintain finished goods inventories. If customers or distributors carry stock, that reduces pressure upon the supplier to maintain inventories and reduce them quickly.
• Planning/Control Systems – Systems employed to manage supply and demand and control the production process have a large effect on INVENTORY.
The systems we refer to are:

- Production Planning
- Master Production Scheduling
- Capacity Requirements Planning

Cost
• Material Costs – Material cost increases (obviously) raise INVENTORY. Lowest unit cost does not necessarily mean lowest cost of doing business, or even lowest cost of material, for that matter. These can be deceptive, because as material costs go up, turns do not decrease, because they are being measured on a new and higher base.
• Overhead – Burden rates of 300%, 500% or more are not uncommon. Having a high overhead rate is not ”bad”, only total costs that are too high are “bad”. Your overhead rate is a reflection of cost distribution and accounting techniques as well. However, if overhead is going up without attendant drops in other areas and if other industry competitors are doing better, then it’s “bad.”

• Labor Content – Reduction of direct labor has been one of the few bright spots in American productivity improvements over the years. The area to look at is labor variances, due to down time, quality problems, material shortages, etc., and in indirect labor. In short, reduce the overhead due to other factors increasing labor.
The preceding sections should give you a better idea of the significance of INVENTORY, and what affects it. If you have been reading carefully, you have already seen opportunities for reduction, since knowing the question is frequently half of the answer.

• Don’t bring it in. An ounce of prevention is worth a pound of cure. Don’t order what you don’t need. For existing commitments, cancel or reschedule where practical.
• If you already have it, ship it. Work on eliminating constraints to getting product shipped. Sell excess inventory at full price/cost, if possible.
• Try to rework or substitute. Attempt to rework, retest inventory, try to substitute it in place of parts that have been specified.
• Salvage it for cash at a reduced rate
• Dump it. If all else fails and it’s really not needed, throw it away, because the tax write-off and lower holding costs alone will make it worthwhile.

This is one of the first things that “turnaround artists” always do to rescue a foundering company. Insist on getting justification for all new INVENTORY expenditures – especially “A” items (most expensive ones). Sign all major approvals and checks yourself. This has an amazing and rapid effect on INVENTORY and has been practiced first-hand by the author and customers.
Use this process to force those responsible to justify what they are doing and why and to think through these policies and their enforcement in a new light – that of investment management.

Conduct basic indoctrination of people affecting INVENTORY most dramatically--planners, buyers, production management, sales, customer service– establish some temporary “edicts” and enforce them until more formal policies/procedures can be established/changed later on. Make sure you know what you are doing before you establish these. Beware of mindless “across the board reduction” edicts that could result in hurting service and profits.
Have your people perform a quick “thumbnail” INVENTORY analysis
Start with items currently on order, in process, or being planned. As Al Agosti of IQR says, “first stop the bleeding. Then take away the knife.” It always amazes me that companies will spend a fortune to analyze INVENTORY, which is already there, but ignore huge impending expenditures, which they can do something about before disaster strikes. To do this, perform a quick “ABC” analysis, identifying only the expensive (“A”) items initially. In most companies, these are only 5

Start with a calculation of what is actually needed: • Go through all the arguments of why people need more, sooner and then get people to agree on how they can avoid doing that.
• Cut new INVENTORY scheduled to come in whenever possible. • Determine right away what can be cancelled, rescheduled, returned to vendor for credit or sold for salvage. Balance the costs of doing this against the relative benefits.
• Work on getting product shipped and billed to get INVENTORY relief.
• Try to match INVENTORY input closer to ship date (reduce lead times and carrying time)

- Major bottlenecks caused by improper manning, defective or poorly maintained equipment, etc.
- Build-ahead and buffer policies
Set goals for inventory down to the level of managers and planners
Do this “rough cut,” for “A” items first-- more detailed analysis comes later. Set targets by planner, buyer, product line or any other meaningful political or production entity that will foster accountability, which you will want to later measure results against and enforce.
Go for the “easy wins” with the best payback first. Don’t fall into “paralysis by analysis.” You can do more in the first few months than you think.

Simply go out to the shop and write down only the identity (part number) and location of all storeroom and/or work-in-process and other inventories, then compare to your records. Don’t even bother to count it (that’s what takes the longest).

As soon as you have some idea of the magnitude of excess/obsolete inventory, work on getting financial and general management to “write it off”, in order to get the tax benefits, where favorable.

Inventory Analysis/Target Setting
Joe Barcy of Inventory Performance Systems calls it the “Divide and Conquer” approach. What he meant is that a company has to bring decisions and measurements down to the level of accountability and below (to the person/part/number/cost element level) and also aggregate this information up to meaningful levels for analysis by various levels of management.
First, group INVENTORY items at the part number level into categories by responsible planner and/or buyer and commodity. Do this in descending
Simply go out to the shop and write down only the identity (part number) and location of all storeroom and/or work-in-process and other inventories, then compare to your records. Don’t even bother to count it (that’s what takes the longest).
Take your “hits” for inventory early
As soon as you have some idea of the magnitude of excess/obsolete inventory, work on getting financial and general management to “write it off”, in order to get the tax benefits, where favorable.
That depletes my INVENTORY of quick fixes. Now it gets a little harder…
Inventory Analysis/Target Setting
Joe Barcy of Inventory Performance Systems calls it the “Divide and Conquer” approach.

y and representatives from various regulatory agencies are working out to design the regulatory requirements for manufacture and sale of combination products
ollar sequence, preferably by projected usage (historical usage, if that’s all you can find, but it has its disadvantages). If you don’t have the ability to do this by computer, do it by hand for the A items first – look up production plans, sales forecasts and buy cards, then extend quantities by approximate costs. Use purchase history, quotes, accounting department support, or whatever you can get. Getting it done fast and approximately is much more important than carrying it out to four decimal places. Remember: money is being wasted while you delay!
Analyze INVENTORY on the following suggested parameters:
1. ABCD classification (by annual usage value)
2. Turnover/investment performance
3. Highest dollars committed
4. Highest dollars in INVENTORY
5. Most longest period coverage planned/available
6. Items with coverage/commitments greater than policy
Once you have all this data, set targets, measure and control performance.
Data Accuracy Program
Set up a formal, ongoing program to clean up and maintain accurate records for inventory, bill-of-material, routings and planning

How to Optimize inventory Levels
If you’re expecting a neat formula here to plug in your numbers, you’re sadly mistaken. It doesn’t exist and if someone tells you it does, it probably doesn’t work. Here are a few ideas that have worked for me:
• Estimate target days coverage using the team’s best judgment for each commodity/product line. Obviously there will be some exception items.
• The “one less” approach: Try reducing inventories in doubtful areas a little bit at a time. Pull back when you get in trouble or when you spot a constraint. Continue after you have relieved the constraint(s) some.
• The lead time/cost build up chart: Construct a graph per product showing the time phased cost buildup in cost of goods sold amount. Have the team meet to see where lead times, lot sizes, attrition factors and buffers can be reduced.
• Modeling tools, Advanc

Key Points
To summarize some important points for your future reference:
• Inventory reduction is one of the cheapest ways to improve profits
• Get control of the “checkbook”!
• Use Pareto’s 80-20% principle to leverage your time and investment – choose your battles – biggest bang for the buck.
• Once of prevention = pound of cure
• Set targets – “divide and conquer”!
• Force accountability- Set up a responsible team- hold it accountable. Include in performance appraisals, incentives
• Question assumptions – eliminate waste
• Doing business right will automatically reduce excess inventory in most cases, but still needs monitoring and control.
