Abstract

Change planning represents a key element for the operation and management of Information Technology infrastructures and services. Its scope ranges from the high level design of a change request to the generation, either manually or automatically, of detailed plans that, if executed, will perform the requested changes (e.g. , modification of network device settings and deployment of new services). A fundamental problem is that, although correct, such detailed plans may not be necessarily aligned with the requirements defined in the business level (e.g. , minimization of the downtime of a given service). To overcome this problem, in this paper we propose a solution for the alignment of change plans with business objectives/constraints. The solution is analyzed experimentally through a prototypical implementation of a decision support system called ChangeAdvisor , which helps operators to understand the trade-offs between alternative change designs.
