Time to scrap your legacy I.T. systems. But how exactly should you go about it? Old and outdated applications lie at the heart of many global supply chains. There's a pressing need to bring them up to date, but companies risk undermining their operations if they attempt a wholesale change. How, then, should they make the decision about which systems to tackle first? What are the criteria for deciding whether a given application has outlived its usefulness? And what's the role of the cloud in future I.T. deployments for supply-chain management? On this episode, we get answers from Dominick Paul, national vice president of strategic solutions for Sungard Availability Services. He discusses what supply-chain managers should consider before updating their legacy applications, and why it's important to proceed with caution.
