A large retail organization has taken on a new project to update their enterprise resource planning software so that they can manage their supply chain on a national level. They want to implement a system that will allow them to track every item through the supply chain. The project sponsor wants to avoid having significant user overhead as the supply chain handles millions of transactions between their warehouses, vendors, and stores daily. To meet the needs the organization is willing to invest significant human resources and capital into the project. The new system must allow for each item in the supply chain to be tracked and audited at any time. It must also allow for vendors to conduct lookups of their supplies to verify their own sales numbers and ensure that they can meet supply demands for the retailer. What technical solution would best meet these requirements? Answers A. Use a distributed ledger and blockchain to record changes within the supply chain B. Use an off the shelf solution from a major vendor C. Install a large database server and record database transactions D. Use the current ERP system and develop changes to it using the Agile methodology
