  1. 1. 06/07/2009
  2. 2. Use scenarios: target user and their needs <ul><li>Goal </li></ul><ul><li>Develop a system (Share.TEC) that responds suitably to end-user requirements </li></ul><ul><li>How </li></ul><ul><li>Identify the actual needs of the users </li></ul><ul><li>Define the user-level services </li></ul><ul><li>Give information to help developing a mock-up </li></ul>CENEC Use scenarios: target users and their needs 06/07/2009
  3. 3. Use scenarios: target user and their needs <ul><li>Identify the actual needs of the users </li></ul><ul><li>Who are the users of the system? </li></ul><ul><li>Teacher educator & student teacher (pre- and in-service teachers) </li></ul><ul><li>Educational publisher </li></ul><ul><li>Educational content provider </li></ul>CENEC Use scenarios: target users and their needs 06/07/2009
  4. 4. Use scenarios: target user and their needs <ul><li>Identify the actual needs of the users </li></ul><ul><li>Which are the needs of our users? (1) </li></ul><ul><li>Teacher educator & student teacher </li></ul><ul><ul><li>Seek content that supports self-directed learning and training activities </li></ul></ul><ul><ul><li>Share educational and professional practices and resources with their peers. </li></ul></ul>CENEC Use scenarios: target users and their needs 06/07/2009
  5. 5. Use scenarios: target user and their needs <ul><li>Identify the actual needs of the users </li></ul><ul><li>Which are the needs of our users? (2) </li></ul><ul><li>Educational publisher </li></ul><ul><ul><li>Access to a wide market for digital content </li></ul></ul><ul><ul><li>Access to a federated system capable of reaching users across Europe t </li></ul></ul><ul><ul><li>Monitor trends at European level and identify emerging user needs </li></ul></ul>CENEC Use scenarios: target users and their needs 06/07/2009
  6. 6. Use scenarios: target user and their needs <ul><li>Identify the actual needs of the users </li></ul><ul><li>Which are the needs of our users? (3) </li></ul><ul><li>Educational content provider </li></ul><ul><ul><li>Access to a wide user community capable to providing rapids feedback for content development </li></ul></ul><ul><ul><li>Test their potential </li></ul></ul><ul><ul><li>Monitor trends at European level and identify emerging user needs </li></ul></ul>CENEC Use scenarios: target users and their needs 06/07/2009
  7. 7. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Scenarios and use cases (1) </li></ul><ul><li>Development of detailed and comprehensive use cases can be a suitable approach for defining user-level services </li></ul><ul><li>Use cases are useful not only in the system development but also as communication point with the end users and the varios stakeholders related to the project </li></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  8. 8. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Scenarios and use cases (2) </li></ul><ul><li>Use cases are a formal definition of system processes </li></ul><ul><ul><li>A scenario describe a sequence of user actions in general terms </li></ul></ul><ul><ul><li>A use case derives from a scenario and describes a specific system function related to a specific task </li></ul></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  9. 9. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Which are the main scenarios of our system? </li></ul><ul><li>Registration and authentication </li></ul><ul><li>Looking for digital content </li></ul><ul><li>Sharing experience about content reuse </li></ul><ul><li>Searching for users </li></ul><ul><li>Adding a digital content description to Share.TEC </li></ul><ul><li>View digital content </li></ul><ul><li>Publishing commercial contents in the Share.TEC federated system </li></ul><ul><li>Testing new digital contents in the Share.TEC system </li></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  10. 10. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Scenarios in details (an example) </li></ul><ul><li>Looking for digital content ( The user is searching for content ) </li></ul><ul><li>Use cases: </li></ul><ul><ul><li>Search using basic options </li></ul></ul><ul><ul><li>Search using advanced options </li></ul></ul><ul><ul><li>Search using personalized options </li></ul></ul><ul><ul><li>Filter using advanced options </li></ul></ul><ul><ul><li>Filter using personalized options </li></ul></ul><ul><ul><li>Browsing according to the ontology Set automatic notification system </li></ul></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  11. 11. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Validation process </li></ul><ul><li>Since use cases define services that will be included in the platform prototype, it is necessary that use cases: </li></ul><ul><ul><ul><li>explicit all the services of the platform; </li></ul></ul></ul><ul><ul><ul><li>are not overlapping; </li></ul></ul></ul><ul><ul><ul><li>describe services that are really useful </li></ul></ul></ul><ul><li>Therefore, a validation process that involes the partners of the project as well as external experts and end users it’s very important. </li></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  12. 12. Use scenarios: target user and their needs <ul><li>Define the user-level services </li></ul><ul><li>Life cycle of use cases </li></ul><ul><li>The use cases definition is a work in progress that depends on the system assessment and evaluation </li></ul><ul><li>The interactions with others partners and with the target users is very important ( questionnaire TE) </li></ul><ul><li>Based on internal and external feedback use cases will be countinuously, as a consequence also the system prototype will be refined. </li></ul>Use scenarios: target users and their needs CENEC 06/07/2009
  13. 13. Use scenarios: target user and their needs <ul><li>Define the user-level services: the road ahead </li></ul><ul><li>Following the feedback gathered during last months by the experts and by the end users, Scenarios will be integrated with the introductions of some Use Cases dedicated to the multicultural aspect of the project. </li></ul>Use scenarios: target users and their needs CENEC 06/07/2009
