Insufficient market transparency
Supply and demand overview is restricted to participants network
Protective behaviour strengthens missing transparency and inhibits the network growth
Missing and low quality documenation hinders a smoth transaction
Objective performance and reliability indicators are missing (only brand awareness and personal experience)
Most showstoppers appear only after initial effort was made (wasted time)
Placeholders and incorrect stock availability reduces the business satisfaction
Distributed procurement process
Many roles involved
Low connectivity & lack of interfaces
