Every successful business is powered by legacy technology and applications which need to evolve. Vendors, Consultants and New Tech Enthusiasts all have the answer – Switch to Our Technology, Outsource, Use a New Language/Platform. Each of these options comes with major business and technical risks, and costs, and long uncertain delivery dates.
In this talk we describe an alternative lean approach to legacy evolution that focuses on high value near-term tactical business and technical innovations. We focus on legacy data rather than legacy code which has been the primary focus for traditional legacy approaches. We illustrate common patterns for identifying high return opportunities and techniques for high payback. We discuss risk mitigation and management buy in for perceived high risk approaches.
