This is a way for businesses to reduce the risk of introducing change. Many of us would have seen a bottleneck reduction project proceed only to find that the project benefits are reduced because another bottleneck arises. Not only is the capital payback extended, but it is often difficult to regain credibility with the work force. Effective modelling and simulation will reduce the chances of these problems occurring and increase the certainty that proposed changes will deliver the anticipated benefits.

There are also many occasions when it is desirable to reduce costs to maintain competitiveness but a reduction in service levels is not acceptable. Modelling and simulation offer the opportunity to try changes out on your computer rather than your customers!

To achieve maximum value a model needs to be easily understood and a modelling package needs to be easy to use. The simple set of symbols and the hierarchical nature of the IDEF0 methodology requires minimal training.
