What do you see as the future innovations and technologies for the procurement sector?

Market Dojo will be attending the eWorld event in London on the 27th of September. The event demonstrates the latest innovations and technologies in procurement, but I wanted to know what you think will be the next leading innovation or technology in the procurement and supply-chain sector? eSourcing Software? eMarketplaces? Procurement training programs? Total cloud-based procurement programs? Artificial intelligence? Big data analysis?
