Datasheet 0021 - Optimus Forecasting and Inventory Management
“Our raw materials inventory dropped by £1.1million
in
18 months. We reduced inventory cover from 12 weeks to 7.5 weeks with
no fall-off in production”
Invensys Group, UK
“We reduced inventory by 11 per cent and boosted
availability from 87 per cent to 96 per cent in the automotive glass after-sales
market – all within 12 months”
Shatterprufe, South Africa
“Our product range doubled from 7,500 to 15,000
items over two years with no increase in inventory investment”
Hella Ltd, UK

Take the guesswork out of managing inventory and save
money
Inventory is not an asset, but a liability. It is working
capital – and it is a risk. Every company needs to reduce the risk,
take the guesswork out of managing inventory and increase productivity,
releasing working capital in the process.
Our methodology – Optimus – provides the strategic
input that links the service objectives of a business to the processes
and decisions involved in stock replenishment for each of its line items.
Not
just a product – an inventory methodology
Optimus is a combination of advanced strategic modelling
software and a practical hands-on focus on people and processes.
World-class modelling tools identify and quantify the
causes of inventory at each node in the supply chain, improve demand forecasting
and set appropriate stockholding targets. The system identifies the key
issues requiring attention to yield the greatest results in
- Supplier Management
- Expediting
- Order replenishment
- Demand forecasting
- Safety stock levels
- Order pipeline monitoring
- Excess stock management
The Optimus methodology has a dramatic impact on return
on investment by achieving large reductions in inventory while increasing
sales and market share through higher availability.
The value of availability
For sales, in an increasingly competitive environment,
where product differentiation and brand loyalty are on the wane, product
availability plays a critical role in securing new business and customer
retention. For services, the customer’s absolute measure is availability
– if it is not there when they need it, you have failed.
We have developed methodologies and decision-support tools to meet these
needs – to create and sustain inventory optimisation throughout
the supply chain – driven by the compulsion to maximise customer
satisfaction.
Optimus utilises breakthrough technology that quantifies
the value of availability and conversely, the cost of stock-outs. Stock
turn and availability targets can be set stock turn and availability targets
can be set to maximise customer service and maximise return on investment.
The Optimus core process
To optimise the inventory chain, companies must manage
and reduce risk at each node. This requires a structured methodology,
improved forecasting and supply management and the use of advanced modelling
tools.
- Risk Sources. Uncertainty, both upstream (supply
reliability) and downstream (forecast accuracy), is the major driver
of risk and the major cause of inventory
- Risk Multipliers. The stock replenishment cycle,
review periods and lead time all act as risk multipliers, leading to
higher levels of inventory
- The Management Process. Only by reducing uncertainty
at the source, and manipulating the risk multipliers, can companies
reduce risk and reduce the amount of safety stock needed for each line
item.
- Strategic Plans. It is vital to integrate marketing
objectives and target availability levels into overall investment strategies
and ensure that these are represented in every recommended order.
- Inventory Models. Only by modelling the inventory
investment required to support different availability level targets
in what-if scenarios, can appropriate and achievable inventory investment
targets be set.

Key Optimus components
- Forecasting, using a ‘tournament’ forecast
method which runs algorithms and optimises parameters;
- Policy setting, for hierarchical categories, optimising
service and inventory levels;
- Supplier and lead time evaluation, monitoring and
reviewing performance and risk contribution;
- Distribution Requirements Planning. The Optimus
model is based on actual requirements over multiple distribution outlets
as well as historical performance;
- Reporting using a management cockpit and specific
reports;
- Intelligence, continually monitoring and comparing
inventory transactions against policy;
- Key Performance Indicators clearly showing any action
required to maintain optimum inventory levels against business objectives.
Implementing Optimus – Shared Risk
Optimus is designed to operate in conjunction with any
ERP inventory control module which records stock balances, stock movement
transactions and item level inventory policies including TROPOS, SAP,
Oracle, Baan, BPCS, Sage(Tetra) etc. The data is extracted from the host
ERP system into Optimus, which runs in a two tier client/server architecture,
typically a Windows NT or Unix system. Data integration is achieved through
simple ASCII file transfer.
Once the interfaces with the host system have been set
up, the key to sustainable improvements in inventory management is the
identification of the root cause of inventory, modelling the improvement
options, and monitoring the effect of the recommendations.
SSI will install the Optimus software tools and provide
a ROI assessment on the client’s data from a shared risk assignment,
typically lasting twenty days. The decision to proceed can then be made
on the basis of improvements identified and evaluated, giving a visible
cost justification. Optimus can be implemented through conventional software
license and knowledge transfer, managed services with no software investment,
or on a risk-reward basis against agreed targets.
