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

3rd User Community Workshop in 2013

Report from 1st 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 community’s 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 <role> I want <something> so that <benefit>”

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

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

2nd Workshop

• We show an intermediate snapshot of the TELEIOS system

• Components are still under development

• No formal evaluation of the functionalities is foreseen at this point in time

• We solicit your feedback through:

• Interactive demonstrations and discussions

• Feedback questionnaire:

• Consists of a set of generic questions concerning your interests and expertise followed by specific questions for each individual session

• Time is allocated at the end of each session for filling out the questionnaires

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
