Agile Modernization Framework for Decision Making in Legacy Environments
Agile Modernization Framework for Decision Making in Legacy Environments
ABSTRACT
Development of enhancements in a legacy environment poses a major application development challenge to many finance and insurance companies. Investment in modernizing architectures does not always immediately realize operational and customer-perceivable value mandated of agile environments. And top-down service portfolio management does not consider architecture impact on decision making to make the priorities and investment realistic. To address these challenges we provide the Agile Modernization Framework (AMF) for systematic decision-making that includes bottom-up architectural and infrastructure information along with top-down and strategic customer and operational needs to make business decisions. We show how this unique hybrid prescriptive framework 1) guides the decision making of legacy-related application features, 2) aligns and constrains implementation in the context of an agile business environment and strategy, and 3) applies to realistic examples where services are often based on shared components and numerous services are involved in complex interrelationships.
