Necessity for Standardizing Electronic
Bidding Systems
If each public purchaser develops an
original electronic bidding system
individually...

When an Electronic Bidding Systemusing the core system is developed...

Many different systems arejumbled indiscriminately.

The common core is customized
for each public purchasers.

High development cost andconfusion among bidders!

Low development costand confusion amongbidders is Avoided
