Enterprise
based Inventory Management
in the Steel Service Center Industry
White Paper
Author: Doug Baldwin
Integrated Steel Management Inc. © November 2002
Overview:
The
Steel Service Center Industry continues to face the challenges
of operating in a highly competitive marketplace, where profitability
has been significantly affected by increased customer demands
for value-added services, volatile steel pricing, just-in-time
production programs and reduced margins. Service Centers that
have either survived the industry meltdown of the early ‘80’s,
or have started operations since that time, are acutely aware
that the times of fat margins and a cavalier approach to quality,
and inventory management are long gone. The challenge today, is
to effectively manage and control the procurement, sale, processing,
and logistics of the inventory cycle, while accurately trackoing
the costs associated with inventory transactions and maintaining
the integrity of material traceability. It is these business elements
that are the major contributing factors to the success of any
Service Center.
This White
Paper looks at the problems facing Service Center’s that
are currently using “legacy” inventory management
systems that were developed in the 80’s or Service Centers
that are just now, discovering the inadequacies of their existing
IT systems. The White Paper provides an insight into how the Steel
Service Center Management (SSCM) Enterprise System addresses these
challenges by utilizing a common sense approach and leading edge
technology to provide the toolset to allow management, sales and
production staff to effectively track and manage inventory through
out the inventory cycle.
Inventory Control
– the Pitfalls:
The most
common cause of business failures in the Steel Service Center
Industry is poorly managed inventory. High inventory levels, aged
stock, ill-advised purchases, poor material resource planning
– can all contribute to a rapid fall into the abyss of business
failure or staggering profit losses. How often has senior management
watched inventory levels creep upward in an unabated march to
the inevitable profit swallowing write down? How many Service
Center’s have been the recipient of a huge surprise at year
end when physical inventory counts reveal a huge disparity to
booked value, or finding material you thought was located at an
outside warehouse has gone astray?
The most common cause of these surprises is the inability of many
information systems to provide management with the ability to
effectively plan procurement, accurately track inventory movement,
trace parent and produced inventory to the source, and allocate
real costs to inventory items.
Material
Resource Planning and Procurement
Many business
solutions that are currently in use by the Service Center industry
do not provide the depth of reporting or application tools to
effectively determine and manage inventory requirements. Then
there is the over-kill system that relies so heavily on automated
triggers, that they are often discarded because the maintenance
required to address the anomalies is not worth the effort expended
to correct the data. This usually results in Purchasing personnel
being fully dependent on Sales personnel to advise them what inventory
is required and when. A system that cannot effectively provide
the means to requisition material based on customer inventory
requirements often results in material and delivery shortfalls
and/or high inventory levels. The inability to effectively track
the associated carrying costs for inventory levels beyond requirements
then becomes a hidden cost that can be a huge burden on the profitability
of the company.
Many
systems do not have the ability to provide management with the
information they require to consolidate on-hand, on-order, in-process
and produced material into a meaningful format that allows effective
management of procurement and expediting.
Inventory
Logistics
In today’s
frantic just-in-time environment, Services Centers are faced with
the management problem of tracking inventory movement from vendor
warehouse, internal or external storage locations, outside processor
warehouses, customer warehouses etc. The ease with which a coil
can be lost or duplicated right in your own warehouse by an input
error or omission is a common problem for Service Centers utilizing
older legacy systems with little integration integrity or data
validations. How many times has a production order been returned
because the material selected for processing cannot be physically
located? How many times has a carrier returned to the production
facility from a vendor or storage location, because the material
cannot be located? In most instances this material remains unavailable
for processing or sale until located, usually during an inventory
count.
Traceability
The ability
to trace inventory back to the vendor source has become a nightmare
for many companies that do not have the ability in their system
to capture and track source material information through out the
life cycle of the material. Many systems provide a tracing mechanism
in their application that is time consuming and frustrating particularly
for Quality personnel attempting to pull together the information
for a Nonconformance Report or Vendor Claim. The inability to
adequately trace material to the source can result in rejected
vendor claims, material certification errors and lost revenue.
Cost
Allocation
In the
past, standard costing for added value inventory costs associated
with processing, freight, outside processing, storage, scrap etc.
have been at the best, estimates. The dartboard approach to calculating
these costs and applying them to material often results in margin
anomalies that often times cannot even be analyzed. How can management
be sure that all costs have been recorded and more importantly,
are these costs accurate? For many Service Centers this requires
exhausting detailed analysis and painstaking inventory maintenance
at every step of the inventory cycle.
Freight
costs are a prime example. Many companies utilize systems that
automatically apply a freight rate based on the carrier vendor’s
quoted rate per hundredweight to or from a destination. As material
is moved, this rate is applied by the system to the cost component
of the individual shipment based on the destination and weight
of the inventory. While this provides an accurate rate based on
the quoted price, it does not factor the true cost of the shipment,
when a load contains multiple drops at different destinations,
fuel surcharges, drop charges etc. Most carriers charge a minimum
load charge to the farthest destination. For a full load that
has one drop 200 miles away and several drops at 50 mile and 100-mile
destinations – the carrier will submit a bill for a full
load based on the farthest destination. Based on the destination
rates applied by the system, the two shipments made to the drops
along the way, would not reflect the actual freight costs incurred,
based on the carrier’s billing. This variance would not
be reflected in the freight cost allocated to the material and
the margin analysis on the shipment is affected. If the system
has no ability to match freight costs to the carrier’s invoice,
this additional cost is likely to be charged to the booked value
of the inventory, ultimately causing a shortfall in the cost of
goods sold for these sales.
Processing
costs are difficult to estimate accurately and once again Service
Centers are faced with the standard cost base pitfall that may
or may not hit the target for true allocation of production costs.
Did the production work order capture the downtime associated
with pulling a coil that was off gauge? Was additional scrap incurred
for those laps that needed to be removed for surface imperfections?
What was the actual time it took to process material applied to
a production work order. Is my estimated scrap calculation anywhere
close to my actual?
How can
storage and carrying costs be accurately calculated and added
to inventory? What happens if they change?
Inventory Management
- The Common Sense Solution
Steel
Service Centers require a management information system that provides
a cost effective business solution to applying modern inventory
management methods utilizing a common sense approach.
Significant
design consideration was expended by the developers of SSCM to
approach the Inventory Management requirements of a modern Steel
Service Center. The design of the system is very much centered
around Inventory Management and is the result of many years of
first hand knowledge and analysis of the problems associated with
the inability to capture or retrieve data that is vital to the
effective control and management of Inventory. This shortcoming
is inherent in many enterprise systems and packaged software solutions.
Management
and users need to have the ability to utilize a system that can
provide the application tools required to accurately capture,
track and analyze all aspects of the inventory cycle associated
with their operation. The system needs to fully integrate all
applications to seamlessly validate and update inventory related
data in real-time and provide the means to review and analyze
inventory related transactions effortlessly. The costs associated
with inventory transactions need to be automatically allocated
by the system in a manner that is accurate and can be validated,
so that variances can be identified and required corrections can
be easily reallocated.
Users
require a system that can give them one stop access to selected
inventory records, with out having to open and close screens displays,
or remember key record id’s to access related data, stored
in other applications. The system should provide screen access
to all Sales, Production, Purchasing, Logistics, Quality and Invoicing
data pertinent to the selected inventory record.
SSCM provides
all of these tools in a unique and innovative set of applications
that gives the Service Center complete control of Inventory Management.
Steel Service
Center Manager (SSCM) = Sensible Inventory Management
SSCM is the culmination of over 25 years of analytical research
and hands–on experience gathered in the Metals Service Center
Industry in North America.
The SSCM business solution combines leading-edge system architecture
and MicroSoft based application components to provide the Metals
Industry with an information system that is easy to use, highly
scaleable and extremely flexible.
The system
has been designed around the basic premise that Inventory Management
is the key to profitability.
The following
commentary details how SSCM provides a common sense business solution
to Inventory Management.
Material
Procurement, and Material Resource Planning
SSCM’s
purchasing application integrates Material Resource Planning,
Material Requisitions, Request for Quotations and Material Purchase
Orders into a blended management tool that allows management to
effectively manage material procurement and expediting.
MRP’s
are created to record each customer’s weekly inventory requirements
utilizing company specific minimum and maximum target weeks to
calculate the inventory levels required to satisfy the customer’s
needs. ( Figure 1)
Figure
1 - Material Resource Planning – Header/Customer Product
Display
Parent material attributes of type, gauge, grade, width, ASTM
etc. are entered for each MRP. The MRP is then completed by entering
the specific customer product id or ids and along with the corresponding
weekly requirements for each item. MRP’s are unique records
and are customer specific. This allows the system to retrieve
and display current inventory levels and variance details for
both master coils, in process material and finished cut stock.
At a glance
the user can see on-hand, on-order and variance summary totals
for master stock and cut stock. (Figure 2)
Figure
2 - Material Resource Planning – Material on Order Display
A mouse click
provides drill downs to purchase order information and material
requisitions associated with the MRP record. (Figure 3) The user
can then use this information to monitor and manage inventory
requirements.
MRP reporting
allows the sales and purchasing department to review, analyze
and maintain inventory levels.
Figure

Display
A summary
of Stock Requirements allows the user to review at a glance,
inventory levels for on hand stock both master coil and cut stock
as well as on order inventory. (Figure 4)
Figure
4 - Material Resource Planning – Stock Requirements Display
SSCM enforces the creation of material requisitions for material
that is to be allocated for a specific customer. Purchase order
line items utilize the requisition to allocate and reserve material
on order to specific customers and this is passed to the inventory
when received.
The purchasing
application also allows the purchasing department to create Requests
for Quotations to monitor and manage vendor quotations and review
pricing and delivery responses from the vendor.
While
many systems currently available, have incorporated features to
automate the purchasing by automatically creating orders based
on pre-determined criteria, our research has revealed this feature
requires constant maintenance and actually increases the margin
for error.
SSCM enables
the effective control of procurement by providing the user with
a sensible approach to reviewing and maintaining inventory levels
that are optimum for customer satisfaction, production planning
and reduction of aged inventory and the carrying costs.
Inventory
Logistics
Material
movement is tracked efficiently through SSCM’s logistic
system. The application allows the user to easily create shipping
orders to handle virtually all movement of inventory. This includes
material shipments to and from vendors or processors, movements
of inventory from branch warehouses or third party locations,
and customer product shipments and returns. The system’s
table driven logic uses destination codes to identify locations
and allows the system to calculate, and store a variety of freight
related costs that are vendor specific. Vendor freight rates for
minimum loads, fuel surcharge, drop charges, waiting charges etc,
are easily entered for each vendor. The creation of shipping orders
to track inventory movement allows companies to apply shipments
to a load and assign the load to a carrier. Inventory records
are updated to reflect the new location code for all items that
are shipped. This feature allows complete control of inventory
at a variety of locations.
Once dispatched
freight calculations are applied to the shipping orders based
on the costing rules that apply to the carrier. The resultant
costs are then prorated back to the cost components of the inventory
items to ensure that the real costs are captured and distributed.
The system allows freight recalculations and user overrides where
a flat one time rate is used for the load.
SSCM’s
invoice matching component provides a dynamic method to easily
match the carrier invoice to the shipment and compare the costs
allocated by SSCM to the actual costs contained on the billing.
Variances are immediately displayed and the user can easily investigate
the cause prior to posting. Variances can be booked or reallocated
to the shipment.
This costing
method ensures that all freight costs are accurately recorded
in the inventory system.
Inventory
Traceability
The Inventory Management component of the SSCM system is the nerve
center for inventory control. All inventory transactions are captured
and stored uniquely for each inventory item created in the system.
(Figure 5) All finished products, returns to stock, and balance
of material returns, retain full traceability to the original
master material no matter how many subsequent processes the finished
product may endure before shipment. Master inventory records that
identify heat numbers, mill ID numbers, vendor id etc. are passed
to the finished product consistently and without error. This guarantees
the integrity of all finished products back to the source material.
Figure 5 - Tag Inventory – Material Information Display
The tag
inventory module allows the user to view and browse a complete
history of the life cycle of the master coil through processing
to shipment. (Figure 6) Once again drill down features allow the
user to view pertinent documents such as sales order, work order,
receiving report, heat chemistry and physicals, shipment information,
produced cuts, quality info etc. – all with the click of
a mouse from a single display.
Figure
6 – Material History Display (Cut Tag Selected)
In addition, the SSCM system has robust audit tracking capability
for all major application components including tag inventory.
Audit trails are captured for all transactions and/or user edits
and can be viewed on screen. The audit record contains the component
that was added or changed, the value before the change
and the new value, identified by the user name and date/time the
record was updated. (Figure 7)
Figure
7 - Tag Audit Display (Audit Detail Selected)
SSCM gives
the user a powerful tool to review and manage inventory records
from an easy to use display that provides a detailed history of
every item received into the system and single mouse click access
to related records in other applications.
Cost Allocation
and Margin Analysis
SSCM ensures
that all cost components associated with inventory are captured
and maintained through the inventory life cycle. From creation
date to shipment date costs are recorded and validated for all
processes. Exception and variance reporting is captured through
SSCM’s innovative A/P invoice matching feature that provides
the user to match vendor invoices to verify inventory cost components
for material purchases, freight in and out, fuel surcharges, drop
charges, outside processing costs, storage costs etc. Virtually
any vendor related added value cost component is uniquely identified
and verified to the recorded inventory cost.
Internal
production costs are handled efficiently and utilize activity
based costing and/or standard based costing. SSCM suggests that
both methods be used to compare anomalies between standard based
estimates and real time costing.
SSCM’s
Production Processing component handles scrap and processing cost
calculation and allocation. When a work order is created and the
setup details are entered scrap weights and percentages are dynamically
estimated. Each setup can have one or more setup line items. The
estimated weight of each piece to be generated is dynamically
calculated based on the average source tag weight and dependant
on the type of process. For example a slitting process would determine
the pounds per inch of width (PIW) and multiply that value times
the width of the finished cut divided by the number of Outside
Diameter (OD) reduction cuts to determine the estimated weight
of each cut. The difference between the sum of the estimated finished
cuts to be produced from each source tag, subtracted from the
average source tag weight is the estimated scrap weight. The system
allows a pre-set scrap rate to be set that will generate a warning
or critical error if the estimated scrap exceeds the pre-set limit.
This feature alerts the user to set-up errors and provides a management
tool to suspend production for orders that are exceed scrap guidelines.
The pre-production work order displays the estimated scrap weight
and percentage values, so that these values can be quickly checked
prior to production. Once the work order has been completed and
all the finished cuts have been weighed the actual scrap weights
and the associated costs are calculated and allocated to each
of the finished cuts. These include costs carried forward from
the master coil and calculated processing costs along with the
allocated scrap costs for the process.
The SSCM
system supports margin analysis calculations throughout the ordering
life cycle. Estimated margins are automatically calculated at
the customer product level, based on entered cost elements such
as material, freight in, freight out, pickling, processing, scrap
etc. to determine the total estimated costs associated with each
product and the selling price assigned for each product. These
estimates can be edited at the sales order level without affecting
the integrity of the cost and pricing components stored in the
customer product table. This feature allows sales personnel to
change the estimated cost of material, for example, in the event
that a higher cost inventory item was substituted due to a no
stock situation. If the sales order is for a ship from stock item
the exact costs are copied from the inventory item selected. All
these values can be expressed in various units of measure and
in several different currencies.
The system
provides a further estimated margin analysis when sales orders
are assigned to a production work order. This analysis calculates
the total estimated margin using the actual costs of material
to be processed, the estimated production costs, estimated scrap
and compares this to the estimated sales order margin analysis
to determine the variance. Final margin analysis is performed
after invoicing to reveal the actual margin vs the estimated margin
for each invoice generated.
These
features allow management to review and analyze estimated margins
from point of sale through production and compare these estimates
to actual margin calculations after shipment and billing.
Cost and
margin analysis are key components of Inventory Management and
SSCM provides a full-featured application that allows management
to apply strategies to reduce costs and improve profitability.

Service Center Management enterprise system represents the new
wave in business solutions geared directly to the Metal Service
Center Industry. This business application presents a new and
innovative approach to managing the complexities of today’s
modern service center. The design aspect of this business solution
combines flexibility and scalability, wrapped up in a fully functional
set of applications that supports a powerful Inventory Management
toolset. Service Centers that have taken a forward looking approach
