IT Industrialisation as Enabler of Global Delivery

This paper presents a concept to utilise different delivery types for the maintenance and evolution of legacy software systems. Based on a so called delivery model cube, three different dimensions are explained that have to be considered for legacy systems in terms of global delivery. The different delivery types come with different preconditions that have to be met before the respective delivery model can be deployed successfully. The prerequisites are classified according to basic concepts within the area of industrialization. We show how the classification can be used to determine appropriate measures for legacy systems when considering global delivery. This is done by localising the envisioned delivery setup within the delivery model cube and automatically identifying necessary preconditions from the corresponding industrialization maturity.
