Let’s first have a look at the global purchasing procedure for led high bay enterprise: document preparation (5 weeks), from sending out LED Lights purchasing information to making decision (8 weeks), from making decision to sending a quotation (2 weeks), from sending a quotation to choosing from bidders (6 weeks), from choosing from bidders to make official purchase (14 weeks), implement purchase (12 weeks), 47 weeks in total. As we can see, this is a standard procedure of centralized bidding purchasing. There is nothing wrong with the process itself, but in this case it was used in global purchasing. Too many departments and organizations are involved which resulted in long process and relatively low purchasing efficiency for LED Lighting company.We can often encounter this in LED lights enterprises: it may take even 2 to 3 years to develop a new lamp supplier. If the new supplier can be found in time, 500,000 dollars can be saved for the company. Two years later one million more dollars will be spent on purchasing, which will be a huge loss.
