Managing uncertainty and complexity in IT based business transformation presents new requirements engineering (RE) challenges where requirements are not known up-front and business outcomes have to be delivered over time in dynamic alignment with market developments. Responding to these challenges necessitates new RE techniques that go beyond the traditional goals of completeness, correctness and consistency and focuses instead on business needs and IT alignment. Using the case of a major IT based business transformation in a large retail bank, this paper outlines new approaches being applied in practice and identifies areas for further RE research.

Modern technologies enable users accessing services using multiple channels. In the service design phase, this poses additional requirements for high software adaptivity along different technical requirements and different user expectations. During execution, services are usually dynamically selected; this service selection phase requires the identification of the most suitable service along the context that characterizes the users in the time instant in which they send the service request. This paper focuses on the selection phase and it aims at providing a framework to define and manage the context in a general environment characterized by adaptivity and multichannel access. An example to demonstrate the suitability and feasibility of the framework is provided referring to the MAIS (Multichannel Adaptive Information Systems) architecture and considering services related to the tourism domain. The MAIS architecture aims at providing automatically and efficiently services with the appropriate features by choosing among many provider offerings.
