The document discusses challenges with user-centered design (UCD) for large, collaborative infrastructure projects like SPICE. It summarizes the SPICE project goals of creating an extendable architecture to support new service creation across networks. Focus groups provided feedback on initial SPICE scenarios, identifying benefits but also privacy, profiling and organizational concerns. Recommendations focused on addressing these issues in revised scenarios and requirements. The document concludes by noting UCD for infrastructures requires an iterative, collaborative approach where methodology is a flexible conversation.

6. SPICE scenarios The touristsâ potential interest in particular activities or items is inferred from their behaviour and is followed by a service push. So when they stop around for a couple of hours at a nice village in the countryside the system advances a proposal suitable to the moment of the day (âdo you want suggestions for a light meal nearby?â). Depending on the userâs reply, additional audio/visual information is provided to get them on the suggested spot. Once they have enjoyed the break, they go back to their car ⊠A multidisciplinary team of managerial, marketing and technical people associated with the promoting organization of âSunrise Inc.â and its technology partners meet to evaluate all the possibilities offered by the SPICE PF components repository. Some services will be created by simply reusing existing elements (e.g. basic components, composite components), while others will be realized as an investment from the involved third parties. Ad hoc contractual and operational models are provided âŠ.

13. Enhanced scenarios it is impossible that the service makes use of usersâ sensitive information in a malicious way since the local SPICE Operator guarantees that userâs personal data (e.g. name, address, mail, telephoneâŠ) are never matched with his context information (e.g. position, mood, availability). Before the service can use sensitive information, the userâs consent must always be given.
