摘要
Embodiments assess risk posed by changing a computer system present within a landscape of other computer systems. Agents provide a central assessment engine with data relevant to considerations such as system criticality, correlation between related systems, and dependence between different systems. The criticality parameter reflects an importance of a system and a corresponding change risk impact. System correlation is measured to allow comparison between systems, and a risk of failure of a change to the systems. Dependencies between systems are measured to define a set of systems to be changed in a coordinated manner. Change statistics collected in a database, may allow correlating systems across various customers, improving accuracy of risk prediction. Embodiments may facilitate iterative planning, where a different dependency permits the definition of smaller sets of systems offering lower risk of failure upon change implementation. Embodiments may allow correlation measurement between systems and a copy created for testing.
