4 Involving the TELEIOS User Community Capturing the requirements of the TELEIOS user community 1st User Community Workshop: User Requirements Analysis: Continuous testing and evaluation of TELEIOS infrastructure by the community 2nd User Community Workshop: Informal but structured feedback: Interactive demonstrations, Discussions and Questionnaires 3rd User Community Workshop: User evaluation of final system Keep the interested stakeholders informed about the evolution of the project and provide a platform to contribute Project Newsletter + Video User Community Workshops Various dissemination activities (publications, presentations, …)

5 Goals of this Workshop To inform you on the evolution and status of TELEIOS Ensuring community support Providing you a platform to express your expectations towards the project To demonstrate the implemented system components and receive your feedback on their usability To demonstrate and to discuss the effectiveness and applicability of innovative methods for improving the access to EO data To collect suggestions and requirements for the system evaluation that will be performed by the end of the project 3 rd User Community Workshop in 2013

6 Report from 1 st Workshop 13 October 2010, hosted by ESA in Frascati Around 30 participants Focus on: presenting the vision of TELEIOS to the international Earth Observation community capturing the EO communitys requirements for the TELEIOS infrastructure to be developed With a methodology based on user stories a set of high-level requirements was successfully captured in the brainstorming sessions In the aftermath of the workshop, these high-level requirements were prioritized and categorized by the TELEIOS use cases leaders NOA and DLR. They serve as a basis for the ongoing use case developments.

User Stories User stories is characterised through the following elements: Short natural language sentences describing desired functionality of a system User stories help in ensuring a common understanding between the different stakeholder groups (developers, end users). They could also be seen as a script for a demonstrator to be developed later on. A user story is a short sentence and might follow the pattern As a I want so that

8 User Stories – Examples (1) As an end user of EO data products, I want to query the products based on their semantic content and on the geographical extent using a single query in order to increase precision and recall in the EO image discovery process and to reduce manual effort (2) As an expert user (EO Scientist / Scientific User, Service Provider), I want to be able to trigger a computation that updates the threshold values based on the information on validated hotspots I have input before (3)As an EO expert, I want to have full transparency of all features of a software I use for Image Information Mining in order to be able to assess the suitability of the generated EO product for my needs

User Stories – Statistics (I) NOA Use Case DLR Use Case Total: 38 User Stories 9

User Stories – Statistics (II) 10

11 Post-Workshop Activities (I)

12 Post-Workshop Activities (II) From User Stories to Use Cases 1.Transfer User Stories into Use Cases Identify user stories that cover functional requirements on the system Group the user stories and identify related user stories and the nature of the relationship such as generalization, specialization. Identify user stories that can be transferred to whole use cases and those that correspond to parts of use cases. Use Cases follows a formal structure (template) and cover details such as preconditions, steps in a success scenario or processed data

21 Introductory Round Some topics that we are interested in: – Please describe your daily work with EO data. Which user role describes your work with EO data best (scientific user, end user, software developer for EO software…) – From the things that you heard before about TELEIOS: – What are your generic expectations towards the project? – How do you expect to benefit in your daily work from the TELEIOS software? – What would you consider the most exciting development? – Is there any important related problem that the TELEIOS project is not addressing? – Which tools are you using for your work with EO data? – Which workshop sessions are of most interest for you? There is time allocated in the afternoon for short use case presentations
